• Cause: raw materials have impurities; extrusion or head temperature is too low; screw friction heat is too high. • Solution: check the raw materials and remove impurities; properly increase the temperature of each section; properly cool the screw.

• Cause: during the cooling and shaping process, the cooling rate of the upper and lower parts of the pipe is inconsistent; the sizing sleeve is too short, and the predetermined diameter effect is poor; the traction force of the tractor is unstable. • Solution: use spray type water tank to make cooling consistent; replace […]

• Reasons: improper formulation of raw materials, poor mixing effect of composite system, unreasonable setting of extrusion process parameters, resulting in poor plasticization. • Solution: Adjust the raw material formula, optimize the mixing effect of the composite system, improve the extrusion process parameters, and improve the quality of plasticization.
