Core Manufacturing Processes

RD Rubber Technology’s core manufacturing processes include:

LIM/LSR (liquid silicone injection molding), Injection Molding, Transfer Molding, and Compression Molding. We work with you to completely analyze your part requirements to determine the most cost-effective molding method as well as the right material composition to meet your specifications.

Our LIM/LSR capabilities offer you the highest precision and closest tolerances of any of the rubber molding processes. LIM/LSR is the ideal method for molding silicone parts where contamination is a problem or when higher volumes are required. Utilizing this method, we can also provide silicone to plastic and silicone to metal molded parts. We also offer ISO Class 8 cleanroom LIM/LSR molding for the most demanding applications.

Rubber Injection Molding can be used to mold a variety of materials including high consistency silicone, nitrile, neoprene, and EPDM but is not limited to these materials. Unlike LIM/LSR the molding of silicone rubber can be customized more readily to suit your custom requirements. This form of molding is also perfect for manufacturing parts where higher volumes are needed from materials other than silicone. These processes allow for repeatability throughout the molding process of tight tolerance parts.

Compression and transfer molding are often used for lower volume and prototype production, thick cross-sectional parts and extremely large production shots.

While the design features of some parts are most suitable to compression or transfer molding, the benefits of transfer and compression molding include lower cost tooling, small production runs and the utilization of HCR (high consistency rubber) materials in focusing on key functional elements of your application.
