Plastic CNC Swiss Screw Machine

Severna's plastic screw machining services produce precision plastic components for use in a broad range of industries and applications. With our large inventory, we can provide fast turn-around as well as a variety of materials for our clients to choose from, such as nylon, phenolic, and Ultem®. Our machinery includes CAM driven Swiss and CNC machines, and we have the ability to perform CAM design in-house. The CAM screw machines have stop spindle and pick up capabilities and can handle parts up to 1" IN diameter; the CNC screw machines handle parts up to 3" in diameter. Severna can produce part features as small as .008" and can work to manufacturing tolerances as tight as ±.0005". Our parts are fully inspected with our Vertex Microvue Precision Measuring System and standard metrology equipment. Additionally, we offer cryogenic and hand deburring, etching, and engraving.
