Plastic Extrusion

Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. The material is gradually melted by the mechanical energy generated by turning screws and by heaters arranged along the barrel.

Plastic Injection

Plastic injection molding is a manufacturing process for producing large quantities of plastic parts. It is typically used when the same part is being created thousands or even millions of times in succession. Injection molding is widely used for manufacturing a variety of parts, from the smallest medical device component to entire body panels of an aircraft. A manufacturing process for producing plastic parts from both thermoplastic and thermosetting materials, injection molding can create parts with complex geometries that many other processes cannot.

PTFE (Teflon®)

NCS also offers PTFE U-cups with Spring Energized Seals that are made from PTFE and other polymer alloys that are corrosive resistant, V-shape cantilever beam spring which maintains constant live compression load and is further energized by system pressure. Available in standard and custom rod and piston and face seal designs to meet all your application requirements.
