Q) I see that you have big range for Rubber Moulding Industry (comprising of more than 7 Models). So, what products and services can a prospective buyer expect when they come to you?

Wang Shihai: Besides customized machines, Yizumi has other 7 machine series because there are so many types of rubber products and they are different in shape and performance demand. Also, customers’ requirements vary a lot, so we recommend different machine series for customers with different products. When customers have no idea of which model fits for them, we will give detailed analysis including TCO evaluation based on customers’ needs.

Q) Do you believe that buyers should evaluate TCO (Total Cost of Ownership) while buying machinery and not just the initial price? Have you been successful in your markets to convince your buyers to evaluate the TCO of equipment?

Wang Shihai: We cannot agree more. And we have several successful cases where customers are satisfied. But we should pay attention to the following points when evaluating TCO:
1. Correct basic data;
2. Verifiable method;
3. Customer’s actual production status;
4. Ultimate benefits oriented for customers.

To make up, modify, or exaggerate the data for winning the orders will affect the final result of TCO, and it should be avoided.

Q) Could you throw some light on how do you compete technologically for your products and service offerings against the European brands? How do you keep pace with the rest of the world to meet your goal of being “No.1 in the rubber injection machine industry” by 2017? 

Wang Shihai: Normally, European brand RIM is high in both performance and price. And it is widely accepted as good machines but what Yizumi prefers is to recommend a machine that is most suitable for the customer. Yizumi adopts modular design including 5 different types of injection plasticising structure (injection volume
0.15L – 80L), 7 types of clamping structure (clamping force 25T – 1800T) in total. The injection plasticising unit in different structure and different volume and clamping unit in different structure and clamping force can form 51 machine models, among which you can have 5 different power systems with more than 30 other optional devices for choices. We offer most suitable technology, machine model and configuration according to customer’s needs. Also, customization is available in order to guarantee that customer can purchase more suitable equipment and avoid the waste of machine performance and functions.

Meanwhile, Yizumi is the first RIM manufacturer to provide globally free after-sales service within warranty. Even after warranty, Yizumi will provide life-long machine maintenance and upgrade services at a fair price.

Besides, in order to launch “low price machine” to the market, some European brands adopts mechanical parts with low quality and cut down some necessary functions. This is totally not in line with the developing trend of rubber moulding industry.

Editor’s Pick: Injection Moulding Of Rubber Product (Part 2)

Continuing with Part 1 of this article, by Dr.S.N.Chakravarty, President – Elastomer Technology Development Society and Ex-Chairman, Indian Rubber Institute (IRI).

Now, let us look  more deeply into Injection moulding process.

Types of Injection Moulding Machines

The following distinctions may be made between the machines used:

  • The toggle or hydraulic mould closing mechanism
  • The plunger or screw type plasticating and injection unit
  • The plunger screw type plastication unit may be further subdivided into those with and those without reciprocating movement.

The fully hydraulic mould clamping mechanism is preferred today.

Operation Principles: Three types of injection moulding operations can be distinguished according to the differences in tool design and process sequence:

  • The conventional
  • The injection forming and
  • The transfer-injection moulding methods

The essential advantage of screw plasticating machines is the very short cycle time which is very important for high volume production, e.g. using rotary table mould arrangements.

One of the requirements for automated rubber injection moulding is to produce a rubber compound of the highest possible uniformity, which is still quite a difficult task even today.

Other important factors depending on controlled mixing are those of optimum and uniform reheological properties, the dispersion of the ingredients  in the compounds, and computer-aided optimization of the vulcanization process, especially for thick-walled moulding. Compounds with consistent processing properties can now be produced using automatically controlled internal mixers.

Another problem is that of automatically feeding the raw material into the injection moulding machine. The strip feeding method in its original form is too imprecise and needs constant manual attention. Recently, however, the strip feeding method has been refined by using strips of precise dimensions wound on drums, allowing limited periods of automated production. Another method used is to feed the compound into the injection moulding machine in granulated form. This may prove to be the best method for fully automated production in the future.

The manufacturer who has installed injection moulding equipment (or who is considering so doing) must consider four general questions:

  • What rubber to use ?
  • How to adjust machine controls ?
  • Which formulations ?
  • What end properties to expect ?

Injection moulding is specially suitable for the mass production of high quality precision components.

For a given barrel temperature, the higher the heat build-up the shorter the cure time. Alternatively, for a fixed injection temperature, the higher the heat build-up the lower the temperature at which the barrel of the machine may be set thus minimizing the danger of premature vulcanization (scorch) in the barrel.

Injection moulding process for elastomeric compound have certain specific advantages over the moulding process.

In Compression and Transfer moulding,  elastomer is pushed into the mould cavity gradually as the mould closes.  Therefore  in the process, though the elastomer gets in contact with the hot surface of the mould , it is not subjected to any pressure, which is  created when the mould is at closing face.  For vulcanization, both temperature & pressure are required.

In injection moulding, mould first closes fully and elastomer is pushed into the mould with high speed.  The cavity of the mould is very quickly filled and a pressure is developed within a very short time, thereby, triggering the process of vulcanization.

In compression moulding process or in transfer moulding process, the flow of material stops immediately when the mould is completely closed. Therefore, typical problems like generation of small gases and vapour, shrinkage of elastomer after vulcanization cannot really be rectified in the above process.

In injection moulding machine there is always a special feature which is known as Post Injection Pressure. Even when the cavity is completely filled and the process of vulcanization has started, the injection unit still continue to push in the elastomer compound for a reasonable length of time ensuring completely porosity free moulding.

Advantages of Injection Moulding

  • Allow automation to be introduced into the moulding operation.
  • Simplifies preparation of rubber: cutting, shaping and weighing of blanks eliminated.
  • Cure times reduced to one-tenth or less compared with compression moulding
  • Materials, trimming and inspection costs reduced.
  • Product quality improved: better dimensional control and more uniform physical properties.

Cure time is considered as a measure of productivity obtainable. This is the time elapsed between injection and opening the mould. For a given set of operating conditions, cure time depends on the thickness of the product.

Early work showed that barrel temperature was one of the most important factors affecting injection temperature.

As Screw speed increases, rubber in the barrel of the injection machine becomes hotter and it is possible to obtain higher injection temperatures and shorter cure times. Cure time, assessed by the hardness of the top, center and bottom of the moulding, closely follows the injection temperature and illustrates that under the prevailing back pressure and barrel temperature conditions there is an optimum screw speed.

Injection temperature increases with elevation of barrel temperature. When there is no screw delay in operation, temperatures above optimum level causes premature vulcanization of rubber in the barrel.

Screw-back pressure is the adjustable hydraulic pressure which acts to pressurize the plasticized rubber in the injection chamber during screw rotation. Injection temperature increases with screw-back pressure.

As the Nozzle orifice diameter is reduced, the injection temperature rises but, below a diameter of 2mm (0.075 in), it levels off .

With a relatively wide nozzle orifice (3.2mm; 0.125 in), an increase in the injection pressure gives a steady rise in injection temperature and a useful reduction in injection time.

Machine manufacturers advise use of 80-90 percent of the maximum available pressure to save wear and tear on the machine.

Compounding

The principles of successful compounding for injection moulding follow the normal rules. The choice of curing system determines properties such as scorch rate, cure rate, reversion resistance, modulus, strength, resilience and ageing resistance. Control of mix viscosity can be used with caution to optimize mould filling time and hence cure time. Required stiffness, strength and cost can be obtained by selection of filler at an appropriate volume loading.

Physical properties (tensile strength, modulus, etc.) of injection moulded components can be expected to be very similar to those made by compression moulding although the modulus of injection moulded samples may be equal to  that of compression moulded samples, the tensile strength tends to be higher. There is also published evidence that injection moulded components are similar to or better than compression moulded ones in respect of elongation at break, tear strength, hardness, resilience and oven ageing resistance. There have also been claims that in some circumstances certain properties (e.g. Dynamic properties ) of injection moulded products are superior.

Particular interest attaches to the injection moulding of thick  components such as engine mounting and shock absorbers – traditional high-quality natural rubber products.  The greatest benefits of injection moulding are obtained when moulding thick sections since injection at  high temperature saves the time required to heat rubber by the relatively slow transfer of heat into a mix of poor thermal conductivity.

Compound with higher Rubber Hydrocarbon content (RHC) is preferable for injection moulding process.

Advantages and Disadvantages of Injection Moulding Process

A comparison of injection moulding with compression moulding shows the following advantages and disadvantages:

Advantages are for example:

  • Reduced preparatory labour
  • Transport and storing of the cut reforms is eliminated.
  • Considerably shorter vulcanization times because of homogeneously preheated material.
  • More homogeneous degree of vulcanisaiton of the finished part at high injection temperature.
  • No bumping.
  • Faster removal of the finished parts
  • Simplification of de-flashing
  • Lowering of the waste and scrap rate
  • Possibility of automation

These advantages are contrasted by the disadvantages of considerably higher investment costs for moulds and machinery. The injection moulding process can not also handle as high volumes as compression moulding.

Economic Efficiency

Which method is most economical for the production of moulded parts, compression moulding with low investment costs but with higher production costs or injection moulding with higher investment costs, depends to a high degree on the number of parts to be produced. Below certain limits it is advantageous to work with low investments but higher wave costs while for high volume production runs  higher investments may be preferable.

However, considering improvement in product quality leading to higher performance  and longer life made by injection moulding process, it is preferable to go for the same.

Taking into account of all factors associated with injection moulding, namely – Capital Investment, higher precision of working, higher (improved) compound cost, Qualified & experienced Technologist needed etc. would lead to a higher cost of the finished product.

Besides choice of Machine & Process one has to keep in mind that performance of a rubber product depends on many other factors which need equal attention. These are, for example, for certain metal to rubber bonded items used by Indian Railway.

  1. Application condition
  2. Environmental condition – Oxygen, Ozone, Fatigue, Displacement Amplitude etc.
  3. Compression under continuous load
  4. Geometry / design of the product – FEA Analysis results

 

Simultaneously to consider which aspects can improve product performance.  For example,

Compound Quality – Homogeneous Mixing / Mix quality (Kneader is not a suitable substitute of internal mixer)

Rheometer provides cure characteristics information but does not indicate mixing quality .

Homogeneity of the compound sheet

Lower Heat Built-up (Resilience /Hysteresis)

Ageing resistance over longer period

Summarizing, it is quite clear that only particular machine or process usage will not lead to improved product performance but combination of all related points development is essential to achieve the desired goal. Any specification should be drawn only after ascertaining the results of these studies.

Editor’s Pick: Injection Moulding Of Rubber Product (Part 1)

Here is an informative piece on injection moulding of rubber products. This article is sent to me by Dr.S.N.Chakravarty, President – Elastomer Technology Development Society and Ex-Chairman, Indian Rubber Institute (IRI).

Moulded rubber products, including rubber to metal bonded items, are manufactured by following process world-wide. Choice of process depends on different factors like Product Geometry, Type of Polymer, Volume, Cost Vs Market Price realization, Manpower & Space etc.

  1. Compression Moulding
  2. Transfer Moulding
  3. Injection Moulding

All the process are well established and widely used. Each process has certain advantages & disadvantages. To get optimum result, you all need suitably developed compound & manpower besides right machine & process.

Compound is developed to meet requirement of laid down specification including special requirement (e.g. dynamic fatigue, heat development, tear resistance, load deflection, etc.) and retention of properties on ageing for specific period at elevated temperature. The later indicates approximate idea for product performance & life. All these obviously have bearing on cost factor.

For different moulding process three major properties or compound behavior is to be considered – Compound Flow Characteristics, Mooney Viscosity and Scorch Characteristics. Each process calls for adjustment of these parameters for suitable working.

Moulding:

Primary purpose of moulding is to provide shape & size of the product. Porosity & Knit in the product are to be avoided. Porosity is caused by moisture in the compound & moulding pressure and Knit by improper compound flow.

In case of Compression moulding, preparation of Blank (shape, size, weight) plays important role to control mould flow / avoid air entrapment and excess flash.

This point is not necessary for Transfer or Injection moulding where feeding system & wastage of semi-scorched compound are more important factor.

Basics of Injection Moulding

Injection Moulding is an important processing technique for converting elastomeric materials into final products. The injection moulding machine automatically performs: raw material feeding, heating, polymer mix plasticization, and mould injection; all operations are performed under controllable conditions of temperature, time, speed, and pressure.

Some peculiar problems arising during injection moulding are associated with the drastic change in rubber compound rheological properties which occur upon vulcanization. In particular, during the filling stage, the rubber compound in the mould-filling process. This is a phenomenon that may lead to the loss of processability of the rubber compound and incomplete mould filling.

Rubber compound or thermosets go through an irreversible chemical change during the forming process. Thus, the critical issue in modeling the injection moulding process for such polymeric materials, is developing a viscosity model that can accurately describe the reheological and chemo-rheological behavior.

As Injection Moulding of Rubber compounds becomes an increasingly important moulding process, an understanding of the nature of coupling the rheological behavior with cure kinetics of rubber compounds and the process itself becomes paramount. Effective control of product quality, as well as the ability to optimize moulding conditions, will depend on a further development of such an understanding.

During Injection Moulding, the Rubber compounds are subjected to high shear rates and as a result experience a thermal history leading to chemical reaction (cross linking). It is recognized that the processibility of a rubber compound is predominantly determined by its viscosity which is balanced by tow effects: the drastic decrease in viscosity with increasing shear rate: and a significant increase in viscosity following the onset of vulcanization. Thus, different rubber compounds not only display different rheological properties, by also possess different chemo-rheological behavior.

Injection Moulding

It is seen that an increase in the inlet temperature does not significantly reduce the cycle time needed to reach a specified cure level. One cannot further raise the inlet temperature to achieve a shorter cycle time due to the possibility of curing in the barrel. Therefore, the distribution of state-of cure in the moulded rubber articles is strongly dependent upon the mould temperature and less dependent upon the inlet temperature.

It is interesting to know how the injection speeds affects the state-of-cure achieved during the same mould cycle duration. For this purpose experiments were conducted in which the injection speed was set  at a definite speed. At this injection speed the calculation shows that there is no cure during the filling stage.

A comparison is made between the predicted and measured gap-wise distribution of state-of-cure in mouldings obtained where cure occurs during filling by  lower injection speed, and where it does not occur during filling at higher injection speed. In the later case, the ultimate state-of-cure achieved in the cure stage is the overall state-of-cure achieved during entire moulding cycle.

In the case when cure occurs during filling, the overall state –of-cure for the entire moulding cycle is the state-of-cure at the end of filling plus the state-of-cure further developed during the cure. Surprisingly, both experimental and predicted gap-wise results show that a higher stat-of-cure is obtained at higher injection speed for the same moulding cycle.

This can be explained by the fact that the rubber material gets into the cavity much faster and therefore has a much longer time to cure in the cavity.

The development of the state-of-cure in the post-filling stage indicated that the mould temperature and injection speed strongly affected the evaluation of state-of-cure within the moulded parts. The effects of the inlet temperature on the state-of-cure was found to be insignificant.

With the increasing demands for high quality and productivity in injection moulding, it has become more important to keep consistently constant dimensional precision. Various properties of polymer such as melt fluidity and density are dependent highly upon temperature. Therefore the consistency in quality is primarily dominated by the temperature variations of mould wall and / or polymer in the barrel.

Fluctuations of these temperatures, however, are indispensable to some extent, due to the heat exchange among polymer, mould, machine and environment, and transient temperature change at the start-up, etc. An adaptive holding pressure control system was developed to get constants product weight by changing holding pressure adapted to the temperature variations.

In Part 2, you will look more deeply into Injection moulding process.

Rubber Machinery and Make In India

The new government of Narendra Modi has enhanced India’s image in the world economy. And a new thrust is being built-up in our manufacturing arena. The flavor of the season has been the rising roar of lion (read “Make in India” logo). Their Facebook page has garnered 2.1 million ‘Likes’ while “#EASEOFDOINGBUSINESS” is popular hash tag on Twitter, reflecting the aspirations of a billion dreams.

And why not?

We have a stable and strong pro-industry government. Global economy is picking up, and India’s core advantages continue to be strong. The government has started well, and already made few minor yet important changes to improve manufacturing sector. Their intent to address obstacles across infrastructure, labour reforms and ease of doing business along with marketing of Brand India are much awaited heartening measures.

Industry Scenario

Rubber machinery comprises of equipment used for Compounding, Mixing, Shaping, and Vulcanizing.

This industry in India manufactures mixers, mixing mills, calenders, extruders, tyre curing presses, tyre moulds, tyre building machines, bias cutters, injection moulding machine, etc.

Estimated at USD 405 million (in 2014), the total market in India is expected to grow at 20% CAGR to USD 580 million by 2016.

According to the Ministry of Heavy Industries (MHI), currently there are 19 units in the organized sector for the manufacture of rubber machinery required for tyre/tube industry. The Indian rubber machinery manufacturing industry is a net exporter. Up to 100% FDI is allowed under the automatic route. Technology collaboration is also freely allowed.

The Indian Rubber Machinery industry is mostly a cluster of SME’s that epitomises the famous “jugaad” entrepreneurial spirit. Over the years, some have grown and compete globally. I wear the name of one such home-grown brand on my chest – Bainite Machines.

Today, some leading global brands in rubber machinery have manufacturing presence in the country through JV’s, wholly owned subsidiaries or technology license arrangements.

Opportunities Galore

Industry has witnessed growth in tandem with our growing economy in the past. Domestic manufacturers have 60% share in the machinery market. Share of imports is 40%, mainly from Far East on account of low price and shorter delivery.

An accepted approach to purchase equipment today follows this thought process – customers need to look West (Europe) for advanced technological machinery if the price tag is affordable or look to China for a low-cost replica.  Another option is to import used-machinery, which is being discarded by the developed world, at an attractive price tag.

Should this approach be refined? Yes, let me explain.

Increased deployment of used-machinery will render our domestic rubber processing industry inefficient in the long run. Because, rubber processors in the developed world are replacing the older machines with new technology machines under the compulsions to reduce the carbon footprint. Old/Used machinery has high operating cost, higher energy consumption as well as loss of productivity from higher maintenance. One industry friend said this aptly “its wishful thinking to assume another enterprises’ liability (used-machinery) can be your long-term asset (productive machinery)”.

Is it then China? Wait!

Recent statistics are interesting. They reveal China is slowly loses its manufacturing edge. And the reasons are multiple. The labour there aspires to work in hi-tech factories creating workforce shortage for labour intensive machine shops. Wages are rising over 10% per year higher than Indian labour cost increase. The rising Yuan (over 7% against dollar in last three years) makes China’s exports costlier while dropping Rupee (over 26% against dollar in last three years) makes India’s imports costlier. Reports of various forex experts suggest China can afford to let the Yuan strengthen a little bit more while Rupee will remain currency competitive as along as India’s trade-deficit is under control. Also for world-wide importers, shipping costs out of Chennai or Mumbai to most ports of the world are competitive (sometimes even lower) to that from Chinese peers.

Most tire producers around the world and few rubber product manufacturers standardize their production processes across their multiple plants. They adopt one machinery manufacturer for one particular production step and develop them to their customization requirements. This is a win-win situation for both the machinery manufacturer and end user.

It’s an acknowledged fact that Indian machinery manufacturers meet 95% of domestic rubber processing industry needs on technology and product range. Our product technologies are at par with leading brands of developed world albeit offered at great cost advantage.

This is also because leading manufacturers know their fundamentals well. We understand machinery and also rubber processing.

The importance of metallurgy, selection of the right material technology, process technology and appropriate designs that bring out machine systems which are long lasting is paramount to us. And hence, we can design and manufacture customized equipment for our customers. This is definitely our niche as compared to competitors of Far-East.

So, I feel, Indian rubber machinery industry is well positioned on the technological and logistical fronts to offer customized USPs in both domestic and export markets.

Sprucing-up

Indian machinery manufacturers have undertaken capacity expansion, upgradation in technology and adoption of best manufacturing practices to compete effectively – both in the domestic and export markets.  At Bainite Machines, we had started a phase-wise replacement of conventional machines with CNC’s since 2011. We invested in latest design and simulation software to build newer machineries like TSS from scratch, introduce latest B-Turbo tangential rotors, and offer value added sophistication to our regular machineries.

The focus is shifting to automation to create customer value. Smart automation on rubber machineries improves productivity of our customers and enhances operator safety. For example, we developed fully automatic Mixing Room technology requiring only one operator and have highest levels of safety interlocks in the complete processing line. For a large rubber processor, adopting technology and automation is sustainable because the benefits include lower cost of production (cost/kg), consistence in quality, superior aesthetics and reduce defects in throughput production.

Operator-friendly, energy-efficient, machinery that are safe, meets global compliance standards and satisfies the technology appetite is the need of the hour. Bainite Machines recognizes this and design customized machinery. Our recently built Hydraulic Ram in Mixers has a Ram up and down time of less than 3 seconds which in conventional mixers used to be 7 – 8 seconds. In a mixing cycle, there are 2–3 Ram Up and Down operations and hence this 4 seconds saving in each stroke is a tremendous boost to productivity.

Our tagline “Technology That Drives Industry” encapsulates Bainite’s dreams to be a technology driver and is equally fuelled by a passion to position an Indian Machinery manufacturer as a significant force to reckon within the global rubber/tire machinery market. Similar aspirations prevail among my industry friends.

What Next – Two Way Bridge?

Indian Rubber Machinery Industry requires further investments to raise the production volumes and technology to global scale. Volumes will give price competitiveness that our customers expect from us. Government has taken few initiatives to fuel growth and support manufacturing industry.

Equally important is the Indian customers’ recognition of the fact that machinery manufacturers must invest a part of the revenue to R&D efforts. This helps them to improve consistency, improvise continuously on quality, innovation and development of new machines. More importantly, customers can expect prompt after-market (spares and service) support when the machinery manufacturing is local.

So, squeezing the domestic machinery manufacturer to unviable price levels during commercial negotiations citing Far-East competition kills all future advancement efforts. This could then become an impediment to your progress as well tomorrow. Indian Rubber Machinery Industry needs your patronage today more than ever.

We have already demonstrated our competence and quality to the world. Rubber processors across the world are regularly reposing their faith on the Indian Rubber Machinery Industry, eventually making us a net exporter. So, there is no restraint that you could think of to establish this two-way bridge for mutual benefit.

A tinge of extra patriotism to “Make in India” can lead to a sustainable partnership between domestic Rubber Processors and Indian Rubber Machinery Manufacturers for the future and boost the domestic economy further.
