Stern Manufacturing is one of the few custom rubber molders that also custom mixes it's own rubber compounds. This critical competitive advantage provides numerous benefits to our clients. With a chemist on staff, Stern Manufacturing is able to develop custom compounds for a specific application or make changes to a formulation per a customer's request, or to improve processing. We offer material that is certified to NSF 61 and can offer material that meets FDA requirements.

Most rubber molders rely on a custom mixer for their material mixing needs, as well as their technical support for formulations. This can add development time to a new project and additional lead time to production orders. Stern Manufacturing stocks most of the common raw ingredients and can mix material when it is needed, for reduced lead times.
