Polycarbonate (PC) material widely processed in Injection molding machine and extrusion machine to manufacturer various kind of plastic products. At Raj Engineering Works we make screw barrel for both type 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 depthSuccessful extrusion of polycarbonate into sheet, tube or profile requires equipment reasonably approximating the some what narrow limits of conditions under which polycarbonate can be successfully processed.
Our screw barrel set can be use for any type of PC processing machines.
Our Highly precised zero tolerance (0.1) and fair price policy make us the most reliable screw barrel manufacturer for PC plastic industry.
