Mold device introduction

Poor mold finish, rust on the cavity surface, poor mold exhaust

Mold assembly is like assembling a machine,
(1) Poor mold finish, rust on the cavity surface, poor mold exhaust.
(2) The gating system of the mold is defective, and the cold material well should be increased, the flow channel, the main flow channel, the shunt channel and the gate should be increased.
(3) the material temperature and mold temperature is low, if necessary, the gate local heating method can be used.
(4) The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and the surface is dark.
(5) The plastic should be fully plasticized, but to prevent the degradation of the material, the heat should be stable, and the cooling should be sufficient, especially the thick wall.
(6) to prevent cold into the parts, if necessary, switch to self-locking spring or reduce the nozzle temperature.
(7) The use of recycled materials is too much, the quality of plastics or colorants is poor, mixed with water vapor or other impurities, and the quality of lubricants used is poor.
(8) The clamping force should be sufficient.
It can be seen that to produce a high-quality plastic products, it takes a lot of effort, not only good plastic raw materials, but also sophisticated processing and production equipment and high-quality and high-precision injection molds. Maijun molds have experienced operators, coupled with sufficient patience and care in the entire production process will surely satisfy you.
