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 Too low mould temperature Increase the mould temperature Surface blocks of extruded finished products Not clean material pipes, contain wastes Clean up material pipe 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 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 Wastes in the material pipe Clean up the material pipe Pits of extruded products Water contained in the raw material Dry the material Too high meting temperature, too fast rotating speed of screw Reduce the meting temperature, and the rotating speed of screw
