Common finished product flaws solution

Product defects	Possible reasons	Handling methods
Extrusion mould distortion	Too short cooling time, not enough cooling for finished products	delay the cooling time
	Too rapid speed for extrusion, forced pull to lead the distortion	Slow down the speed of extrusion die
	Finished product structure with defects	Modify the dies
	Too high temperature for die, poor cooling for finished products	reduce the mould temperature
Knit line	Insufficient injection pressure, too slow injection speed, too small gate and flowing pipe	Increase the injection pressure and injection speed, modify the gate and flowing pipe.
	Too low forming temperature and mould temperature	Increase temperature, increase back pressure or accelerate the rotating speed of screw
	Insufficient exhaust in interflow zone and no run-off pit	Fix exhausting holes in interflow zone and increase the number of run-off pits.
	Use too much release agent	Reduce to use release agent
Poor luster of finished products	Too slow injection speed, insufficient pressure and low mould temperature	Increase the injection speed, injection pressure and mould temperature
	Hydrosphere or grease pollution in the mould cavity	Clean it up
	Poor grinding of mould surface or too small gate and flowing pipe	Modify mould
	Insufficient injection quantity or water contained in the raw material	Increase the injection pressure and injection speed, delay the jetti
Cracks of extrusion mould of finished products	Too low temperature of material or mould	Increase the temperature
	Insufficient stripping lean or improper extrusion way	Modify the mould
	Too small gate	Modify the mould
	Insufficient stripping angle	Modify the mould
Coarse surface of extruded finished products	Too low forming temperature	Increase the temperature, accelerate the rotating speed of screw
Coarse surface of extruded finished products	Too low mould temperature	Increase the mould temperature
Surface blocks of extruded finished products	Not clean material pipes, contain wastes	Clean up material pipe
Surface blocks of extruded finished products	The additive articles such as color master batch are not done according to the requirements	look for the corresponding color master batch
Insufficient extrusion quantity	Insufficient temperature for material pipe	Increase the temperature
Insufficient extrusion quantity	Wastes in the gate or too low speed rate of screw	Clean up the gate or accelerate the rotating spped of screw
Extrusion mould expansion of extruded products	Too low temperature of mould head or too fast rotating speed of screw	Increase the mould head temperature and reduce the rotating speed of screw

	Too fast limited material	Adjust the limited material device
Produce much gas when extruding	Too high melting temperature	Reduce the melting temperature
Produce much gas when extruding	Wastes in the material pipe	Clean up the material pipe
Pits of extruded products	Water contained in the raw material	Dry the material
Pits of extruded products	Too high meting temperature, too fast rotating speed of screw	Reduce the meting temperature, and the rotating speed of screw
