In the field of medical device manufacturing, liquid silicone rubber injection molding (LIM) is a process that has several advantages over other methods. The technology can reduce product strength and weight, while being more cost-effective than some alternatives, and still producing the final product within the parameters set by equipment and regulators.

The Molding Process of Medical Device Manufacturing

There are many kinds of molding processes for medical device manufacturing, including thermoplastic, micro molding, compression molding, transfer molding, etc. Choosing the right molding process is very important in creating a successful and high-quality final product. Here are some common options:

• Transfer Molding

By transfer molding, hydraulic plungers push rubber through the runner and gate into specific cavities. The benefit of transfer molding is that it requires very little setup time, and it is very useful for both small and high-volume production. Contract manufacturing organizations (CMOs) can also use the process for the secondary molding of metal and plastic inserts.

• Compression molding

Compression molding involves the preparation of organosilicon outside of the molding process. Position the shot in each mold cavity, seal with the top, then compress to ensure access to all areas of the mold. The compression molding process is suitable for large geometric parts and encapsulation molding applications.
