Marshall Manufacturing Company has a long history of machining plastics.

It began in the early 1970’s, when the owner was approached by a then “new technology company” seeking prototype filtration components. This product was envisioned for the commercial liquid filtration industry.


Marshall has been involved in commercial filtration products since the 1970s. Marshall was integral in building prototypes for the budding filtration industry.

To this day, we machine components for several filtration companies, utilizing a multitude of plastic materials in a variety of diameters and lengths. In recent years, Marshall has automated several manufacturing cells with robots and mechanized systems, manufacturing over a million parts annually.

Plastic Materials

By the mid-to-late 1970’s Marshall gained confidence with the machining of plastic tubes for the filtration industry. As our customers’ needs for precision plastic components grew, we began to expand our repertoire from tubing to include solid plastic rod stock. Experience machining our day-to-day materials of PVC, CPVC, Noryl, ABS and Polysulfone soon expanded to include polypropylene, polyester, polycarbonate, PEEK, UHMW, Delrin, Teflon, Nylon and Acrylic to name a few. Marshall also has experience with glass-filled plastics and phenolics.

CNC Turning

Similar to the components we machine for our customers from metal, plastic material can be machined in CNC turning centers. Plastic’s machining characteristics differ from metal’s, and some plastics have unique machining attributes compared to other plastics. These machining variations go beyond the differences of rigid plastics and flexible plastics. Cutting speeds, depth of cut, material melting points and tool rake angles are just of few items to be considered when machining plastic.

Swiss Machining

We also offer complete Swiss machining to accurately manufacture smaller plastic parts that require tight tolerances.
