Tianjin Xu Di insulation specializing in the production of plastic extrusion machine, extrusion machine main product warehouse, extrusion machine quality suppliers, extrusion machine manufacturers, plastic extrusion machine - Tianjin Xu Di optimal plastic extruder is composed of mainframe extruder, extruding system, transmission system and heating cooling system. Extrusion system extrusion system including a screw, barrel, hopper, machine head, and the mold, plastic by extrusion and plasticizing system into a homogeneous melt, and in the process established under pressure, by continuous extrusion head screw. ( 1): extruder screw is the most main component, it is directly related to the extruder application scope and productivity, high strength and corrosion resistant alloy steel. ( 2): barrel is a metal cylinder, heat resistant, for general use high compression strength, r ed wear-resistant, corrosion-resistant alloy steel or alloy steel composite steel pipe lined with. Barrel is matched with a screw rod, to achieve plastic crushing, softening, melting, plasticizing, exhaust and compaction, and the molding system uniformly continuous conveying rubber. Generally the length of its barrel diameter of 15 ~ 30 times, to be fully heated and fully plastic plasticizing principle. ( 3): hopper hopper bottom is provided with a cutting device, in order to adjust and cut the material flow, the hopper is arranged in the side view hole and calibration of metering device. ( 4) die and die: die made of alloy steel inner sleeve and outer sleeve is arranged in the carbon steel, die forming die, die is the role of the rotational movement of the plastic melt into parallel linear motion, uniform and smooth ingress die sleeve, and given to the necessary pressure molding plastic. The high-tech, high starting point, high quality, high credibility is the eternal pursuit of Xu di. " Production-class products, provide first-class service" Xu Di people of your commitment. Work together with your common development, create brilliant!
