The fluidity of plastics
     The fluidity of plastics:An indicator to compare the injection molding difficulty level of a plastic material, which like viscosity, is dependent on molding conditions and the properties of polymers. Indicators for measuring the fluidity of plastics: The relative molecular mass, melt flow...
injection molding temperature
Plastic injection molding is an engineering technique that transforms a plastic material into a useful product that is able to retain its original features. The important process factors include injection molding temperature, injection pressure and corresponding effects that affect plasticizing and cooling. 1. Barrel temperature: The temperatures that need...
mold temperature control
Proper Mold Design When molding with engineering plastics, such as POM (polyoxymethylene), PA (nylon), PBT and PET (polyester), the correct mold surface temperature plays a very important role. After mold design meets the basic product requirements, the molding operator is only able to produce great quality products with the help of a...
mold temperature controller
Core Tips: during plastic processing, mold temperature is an important variable that needs to be properly controlled. The perfect temperature control is able to reduce the unit cost of plastic injection molding, improve the quality of molded products, ensure the correct replication of plastic part surface, and guarantee the uniformity of shrinkage. Therefore, mold temperature control must...
injection molding pressure
1,Plastic Injection Molding Pressure This is the pressure caused by plastic flow, and can be measured with sensors on the nozzle or the hydraulic line. It does not have a fixed value. The more difficult it is to fill the mold, the higher the injection pressure is required. The linear pressure is directly related...
