plastic corrugated pipe, plastic corrugated hose extrusion process for what kind of? Plastic granular materials according to the dosage of a molding corrugated hose, the hopper to join barrel, driven by rotating screw, at the same time the raw material receiver tube of external heat. Heats as raw materials in the barrel, screw thread volume shrinking and compression, and turn the screw thread make flip forward material with the barrel, the friction between the screw thread, and other conditions, is pushing forward at the same time of material by plastic into molten gradually. To screw the front of the molten material, due to the resistance of the nozzle and the screw thread pressure, with the increment of the screw pushing forward melting, the back pressure is gradually increased, when the back pressure is greater than the oil cylinder piston screw began to retreat, start charging measurement.
plastic corrugated pipe, corrugated plastic hose back the distance by an extrusion molding plastic corrugated pipe extrusion rate decision, controlled by mixed stroke switch before production. When the back screw to control distance, travel switch, make the screw stop running and retreat, to complete a pre plasticizing process. Corrugated hose has good flexibility, resistance to distortion, bending performance is good, can bear heavier load; Acid, such as lubricating oil, cooling fluid, the surface luster, friction resistance; Carrying capacity, can bear the weight of the foot, not broken, not variant, can quickly recover, and itself without damage; Areas of application: machinery manufacturing, electrical insulation protection, lighting equipment, automobile manufacturing, aerospace equipment, subway, train, automatic control, etc.
