Solution for defects of transparent plastic injection parts Feb 15, 2019
(1) eliminate the interference of gas and other impurities, and fully dry the plastic. (2) reduce the feed temperature, adjust the feed barrel temperature in stages, and appropriately increase the mold temperature. (3) increase the injection pressure and reduce the injection speed. (4) increase or decrease the preplasticized back pressure, reduce the screw speed. (5) improve the exhaust condition ...

Causes of color defects in injection parts Feb 15, 2019
(1) poor mold finish, mold surface rust, mold exhaust is bad. (2) if the casting system of the mold has defects, the cold feed well should be increased, and the flow passage, polishing mainstream passage, diversion passage and gate should be increased. (3) the material temperature and mold temperature are low, if necessary, local heating method of gate can be used. (4) low processing pressure, slo...

Requirements of Thin-wall Injection Molding to Mold Feb 15, 2019
Speed is one of the key factors for the success of thin-wall injection molding. Rapid filling and high pressure can inject molten thermoplastic material into the mold cavity at high speed, to prevent the gate from freezing. If a standard part fills in two seconds, the mold thickness will be reduced by 25%, and the filling time may be reduced by 50% (saving 1 second in time). When thickness decreas...

How does the purity of steel affect the mold performance? Feb 22, 2019
The purity of steel mainly refers to the quantity, type, morphology, size and distribution of non-metallic inclusions in steel. Non-metallic inclusions usually refer to harmful impurities such as oxygen, sulfur, phosphorus, hydrogen and nitrogen remaining in mold steel. The smaller the percentage of these impurities in a unit volume, the higher purity of mold steel. The purity of mold steel ...
