Quality Extrusion Services

Quality Extrusion ServicesStern Companies can supply the talent and engineering expertise required to deliver quality extrusion services, even when faced with demanding specifications and tight timelines.  We have the resources to provide ram and screw extrusion processes, which we apply to a wide range of rubber, sponge and plastic materials.

Stern works with a variety of profiles that can be flat or tubular in multiple sizes, shapes and configurations.  These extruded products end up as rubber tubing, hose, inner tubes, seals and weather stripping.  We are conversant with industry specifications, for example NSF, UL94 HB and UV light stable because our customers and their end users rely on the components we extrude for them.

At Stern Companies, we take quality seriously.  We are ISO / ASQ Certified and meet SAE / ASTM Standards.  Stern has the capacity to handle your project, large or small.
