Silicone Injection molding services produce molded components made from silicone. Silicone rubber is a two-component, synthetic, flexible rubber-like material made from silicone elastomers that can be cured at room temperature into a solid elastomer used in molding. It is heat resistant, durable, and free of allergens or leaches able chemicals. Liquid silicone is similar to normal silicone but has different processing characteristics. It is purchased as a two-part raw material with a grease-like viscosity.
Nowadays injection molding of liquid silicon rubber is becoming increasingly important. One reason for this is the increased performance requirements of the finished articles. In addition, more and more producers of rubber parts are seeing benefits in the high level of automation and productivity.

Various ways of liquid silicone injection molding

Molding processes used by providers of silicon molding services include cast molding, compression molding, dip molding, injection molding, reaction injection molding, rotational molding, and transfer molding.
Whereas in the cast molding process, the liquid material is poured into an open mold, in compression molding a slug of silicone is pressed between 2-heated mold halves. On the other hand dip molding is a process similar to hot-dip coating, in which the finished product is the fused plastisol stripped from the dipped mold. However, in injection molding, liquid silicone is forced into a cooled mold under tremendous pressure. In the Reaction Injection Molding (RIM) process two or more reactive chemicals are mixed at high speed as they are being injected into a mold. In rotational molding hollow molds filled with silicone material are secured to pipe-like spokes that extend from a central hub. In transfer molding, the two mold halves are clamped together and silicone is forced by pressure into the mold.

Why the preferred use of silicone rubber in injection molding

Silastic silicon rubber is a sheer material and so its viscosity depends on shear rate. As the shear rate rises the product becomes lower in viscosity. It is this effect that is very favorable for the injection molding process. At the beginning of the injection process, the injection speed profile should be programmed in such a way that the volume flow is high enough for the liquid silicon rubber-not to begin to vulcanize before the cavity is filled, in order to avoid the scorch of the material. Thus liquid silicon rubber is widely used for the process of injection molding due to its following characteristics:

  1. Solventless with low and versatile viscosity.
  2. Easy mixing and pigmentation
  3. Rapid processing compared to solvent dispersion and usually allows a complete coating to be applied in a single pass
  4. Prime less adhesion to glass and some other substrates.
  5. Meter mixed plastic liquid silicon rubber can be dip-coated or fed to a crosshead for supported extrusion coating.

To sum up

Silicon rubber molding has come a long way over the past two decades. From its roots in a few specialty applications where premium physical properties counted more than the premium price, this thermoset carved out a small but solid niche in the medical and automotive fields. Now, among the proliferation of new applications, that niche has begun to burst at the seams.

Injection Molding in briefly explaining is a method that mold is gotten by cooling and solidifying the heated and melted material injected into the cavity via high pressure. The method is suitable for the mass production of parts with complex shape and is one of the important processing methods. The injection molding process can be broadly divided into the following six stages of “combining mold – injection – packing – cooling – opening mold – product removal “, and once the above process is repeated, products can be continuously produced.

Rapid injection molding

What is Rapid Injection Molding?

Rapid injection molding or rapid tooling injection molding is a popular manufacturing technique that has been idolized for years.  Rapid injection molding is similar to conventional molding, yet different enough to affect how parts are designed. This technique lets companies quickly get low-cost and dimensionally accurate prototypes as well as low-volume production parts from plastics.

Rapid injection molding falls between rapid prototyping and conventional injection molding. This technique supports prototyping, bridge tooling, and low-volume production. Additive methods such as FDM and SLA work well for testing form and fit, but often such parts are not a substitute for testing with real injection molded parts. Rapid injection molding is also fast and cost-effective enough to fix problems when initial designs are not quite right.

Rapid injection molding has increased the quality of a final product by increasing the time companies have to test designs. Some manufacturers did quite a bit of testing with rapid prototype based polyurethane castings, but because the material properties of cast materials can differ significantly from those of injected molded resins, many times testing left unsolved.

What is What is Rapid Injection Mold or Proto mold?

Rapid injection mold and proto mold are two different terms that refer to the same thing. They both describe a type of mold used in rapid injection molding, which is a manufacturing process that allows companies to quickly produce small to medium-sized batches of plastic parts or products.

A rapid injection mold or proto mold is typically made from aluminum or soft steel, which can be created quickly and cost-effectively compared to traditional injection mold. These molds are designed to be used for a shorter period of time and for lower production volumes than traditional injection molding molds.

The use of rapid injection molds or proto molds in rapid injection molding allows companies to quickly produce prototypes or low-volume production runs of plastic parts or products. This process is faster and more cost-effective than traditional injection molding, which requires more time and expense to create molds.

Rapid injection molds or proto molds are a valuable tool for companies that need to quickly produce high-quality plastic parts or products for prototyping, low-volume production, or quick-turnaround projects.

Difference between Rapid plastic Injection Molding and production injection molding

The main difference between rapid plastic injection molding and production injection molding is the production volume and the lead time.

Rapid injection molding is a fast and cost-effective way to produce small to medium-sized batches of parts or products. It uses advanced software and machinery to create molds quickly and efficiently, which reduces the lead time and turnaround time. Rapid injection molding can produce parts or products in a matter of days or weeks, making it suitable for prototyping, low-volume production, and quick-turnaround projects.

Production injection molding, on the other hand, is a more established method of producing parts or products at a larger scale. It involves creating a mold and then injecting molten material into the mold to create the final product. Production injection molding is best suited for larger production runs and can produce high volumes of parts or products at a lower cost per unit. It is ideal for long-term production projects that require consistent quality and high-volume output.

Another difference between rapid tooling injection molding and production injection molding is the cost. Rapid injection molding has higher upfront costs due to the investment in advanced software and machinery. However, it can be more cost-effective for small to medium-sized production runs. Production injection molding, on the other hand, has lower upfront costs and is more cost-effective for larger production runs.

In summary, the main differences between rapid injection molding and production injection molding are the production volume, lead time, and cost. Rapid injection molding is faster, more expensive upfront, and best suited for small to medium-sized production runs, while production injection molding is slower, less expensive upfront, and best suited for larger production runs.

The technique of rapid tooling injection molding makes testing much more beneficial. It is because everyone knows that new products must pass extensive design, prototype evaluation, and functional testing before they are considered ready to distribute to markets. In this case, rapid injection molding becomes one of the best techniques for prototypes that need to undergo design changes during the developmental stage.

By rapid injection molding technique, you can make as many prototypes as possible needed to get the best products, or you can name it pilot production. It is perfect for market testing until the production plastic mold is ready, or about a three or four month wait. When production volume does not justify to make prduction plastic mold, this molding technique can supply production parts.

If you never knew the process of rapid injection molding, the following can help. The process uses aluminum molds milled on 3-axis CNCs instead of the expensive, hardened tool steel molds used with traditional methods. Molds comprise an A-side, sometimes called the cavity side and a B-side, sometimes called the core side. The A-side mounts to the fixed portion of the injection molding press.

Then, in rapid tooling injection molding, resin is injected through this section of the mold into the part cavity by way of the sprue, the path the resin takes until it reaches the runners. These guide the resin to the gate, the location where the plastic enters the part cavity. The B-side, on the other hand, mounts to the moving side of the press and includes the steel ejector pins. Before designing the mold, parts are oriented so they will remain on the B-Side when the mold opens.

The process of rapid injection molding also requires technology, such as 3D CAD with high speed CNC machining equipment to quickly manufacture injection molds. This way is efficient, as it enables the low cost creation of injection-molded prototypes and makes low volume runs of production parts affordable. It allows manufacturers to get prototypes in just few days. It is also a way company’s image since it lets you to have more preparation before launching products.
