ERRORS of squirt PRODUCTS Cause-the generationRemedy Controling Molded Part Dimensions Cause-the generation  The shrinkage of the product  Shrinkage:  The  thickness is too large low pressure cavity, the high level of shrinkage  High temperatures are high shrinkage  The Remedy orientation of the large molecules is large shrinkage  Reduce unnecessary khii thickness  Cavity pressure regulator, plastic suitable temperature Controling Molded Part Dimensions Cracks and Part Breakage The geneneration  Due to the impact from the outside when the mold or residual internal stresses caused video output power make microscopic cracks or stains on the product shine Cause  Due to excess impact  The force of the product taken large  Residual stress  Internal stresses due to processing conditions k reasonable  Due spray-born Cake release stress cracking Remedy  Reduced forces  Improve flow  Increase mold surface temperature, the temperature of the resin flow, reducing pressure spray Products warping Cause  The change throughout the product shrinkage  Product  Mold removed soon Design inappropriate  Use a tape type or style vent fan to turn smooth flow throughout cavity This reduces the stress slip Sink Marks Cause  The shrinkage of the material remedy Remedy  The parameters change presses  Changes plastic shrinkage coefficient smaller  Divide the large veins of the small veins  Putting injection port location to location near thick Splay Cause – the generation  High  The shear modulus dirt is not compatible with plastic Remedy  Increased melting temperature and injection speed reduction Bavia – Flash Remedy Cause – the generation  Adjust  Error between major mold half  Mold clamping force is too low  Melting temperature, cylinder temperature, injection speed and pressure in the mold too high  Mold does not close the appropriate mold  Reinstall the mold clamping force  Reduce the injection pressure, injection speed  Reduced flow temperature and mold temperature  Select the appropriate port position BAVIA Voids Cause – the generation  Adjust the appropriate mold  Reinstall the mold clamping force Remedy  Designing products with the appropriate thickness  Change    Reduce the injection pressure, injection speed Reduced flow temperature and mold temperature Select the appropriate port position position injection port  Reduce the pressure loss of the screw  Add the entrance to the exhaust sound Voids BurnMark Cause – the generation  High injection pressure  High Temperature Plastic  Air Remedy  Reduce the injection pressure  Check the exhaust system  Must material drying before molding, moisture
