Rubber & Silicone Molding - We Handle All Quantities

TEAM Rapid offers rubber injection molding, compression molding, liquid silicone rubber molding to meet your specific projects.


Rubber injection Molding

Rubber Injection Molding 


Rubber injection molding is a branch of injection molding. Rubber is the major injection molding material for this process. The commonly used rubbers include TPE, TPU, TPV, TPR etc., which can in different brand and hardness depends on your project requirements. The tooling methods of this molding is generally same as traditional injection mold tooling. The only different is the material -- rubber, which is soft plastic. The tooling structure can be simplified, and even with no ejection system. As a professional rubber injection mold maker, TEAM Rapid offer not only for the high-volume but also low-volume rubber molding. The undercuts usually release by manual insert for the low-volume rubber molding parts, this can deeply simplify the parting lines and ejection system.  The key point is on how to set the parting lines skillfully to reduce flashes on rubber molded parts.



FAQ about Rubber Injection Molding


1. Why temperature is so important for rubber molding?

Injection molding rubber is sensitive to the temperature. Generally speaking, the increased molding temperature usually reduce the condensation of plastic, which making the molten materials flow and fill the cavities easily and resulting the rubber injection molded parts in better quality surface and greater part weight. In the other hand, increasing too much mold temperature may lead to injection rubber modified and decrease tensile strength of the rubber molded parts. For injection molding, TEAM Rapid strictly follows with the material data sheet to mold the rubber parts, we know the importance of mold temperatures.


2. How to do custom rubber mold parts?

As mentioned above, rubber injection molding is one kind of injection molding. Firstly, we need to build a mold. Secondly, we process the injection molding process. The cycle of rubber injection molding is generally the same as traditional plastic injection molding, which includes mold closed, injection, cooling, plasticizing the resin, ejection, removing the gate and package etc. The general injection molding machine is OK for rubber molding, if you need better configuration, you can ask the rubber injection molding machine manufactures to help with these. For more details, or you have projects need rubber molding, please feel free to contact us.


Compression Molding 


Compression Molding Parts

It is a molding process which places a rubber/silicone(solid) onto an open, heated mold cavity, then close and compress in order to have the material fully contact all areas of the mold to form the shape of cavity. Compression molding vs injection molding? The hydraulic press compression molding is similar to injection molding, but it is different on the injection process. 


Compression Molding Materials


Thermoplastic materials are used commonly in hydraulic press compression molding. At TEAM Rapid, we offer not only compression mold making but also a series of molding materials selection. The materials include:

- Silicone 

- EPDM 

- Urethane

- Polyurethane (PU)

- Polytetrafluoroethylene (PTFE)

- High-density Polyethylene (HDPE) 


FAQ about Compression Molding


What is Compression Molding?

You can take the picture below about our hydraulic press compression molding process, the major molding steps are:

A: Build a mold. The mold is usually a two-plated-mold, the structure is closed and open, and might involve insert structure.

B: Place the molding material (mixed with curing agent) into the heated and open cavity.

C: Close the mold, the material is fully contact all areas of the mold cavity when under compression molding press.

D: Heating the mold through compression molding machine to a certain temperature to make molding rubber cured.

E: Take out the molding then remove the overflows and package.


Compression Molding


Are you looking compression molding caps or some other custom parts? Finding suppliers who do compression molding near me is good, but you can also try the rapid manufacturing services from oversea manufacturer such as TEAM Rapid, we offer high-quality parts in fast delivery but low cost!


Liquid Silicone Rubber Molding 


Liquid Silicone Rubber MoldingWhen you are looking for silicone rubber liquid mold and silicone rubber parts in high precision, Liquid silicone rubber injection molding is the best solution for you! LSR parts are used widely in a range of different industries. Their good properties such as steam resistant, low compression set, conductivity, oil and heat resistant etc. allows it to have excellent performances in working as gasket, keyboard, touch pad, long-term durability components etc. Also, liquid silicone rubber for mold making is OK! 


Conclusion

Rubber injection molding, compression molding, liquid silicone rubber injection molding, which one is the best solution for your project? Contact our team at [email protected] to learn more, our experienced sales engineers will support you to choose the best solution to make high quality silicone rubber parts at low cost.
