Polycarbonate (PC) material is widely processed in Injection molding machines and extrusion machines to manufacturer various kinds of plastic products. At Raj Engineering Works we make screw barrels for both types of PC processing machines.
PC - Single screw (profile, sheet, film ) without vacuum, plain feeding section with vacuum or pressure-relieved grooved feeding section (by increased screw pitch and channel depth Successful extrusion of polycarbonate into a sheet, tube or profile requires equipment reasonably approximating the somewhat narrow limits of conditions under which polycarbonate can be successfully processed.
Our screw barrel set can be used for any type of PC processing machine.
Our Highly precise zero tolerance (0.1) and fair price policy make us the most reliable screw barrel manufacturer for the PC plastic industry.
