Compression Molding Rubber
The first modern rubber product ever produced was compression molded in the home oven of Harvey Firestone in the 1890s. In many ways, not much has changed since for compression molding.
Compression molding rubber involves taking rubber compound or mixed raw material and making "pre-forms" that are in the shape of the end product. These shapes are then loaded, typically by hand, into an open mold. The mold is closed, the rubber cured, and then demoldedtypically by hand.
Compression molding rubber can be cost effective if one or more of the following is true:
- compression molding tooling already exists
- the quantity required is very low
- the part cross-section is very large and it requires a long cure time
Custom Rubber Corp. has been compression molding since its founding in 1956 and has extensive experience in taking on existing tooling.
Custom Rubber Corp. is an active member of the RMA (Rubber Manufacturer's Association) and one benefit to that membership is access to industry-specific operator training for all of our manufacturing methods. If you are interested in seeing a preview of the type of training all of our operators receive, you can visit the online site and learn a little about rubber molding.
