The Principal of Plastic Injection Moulding The so-called plastic injection moulding process refers to: the plastic material in the barrel of an injection molding machine is plasticized into a melt by the sheer heat that is generated by external heating and screw rotation, and then the melt is fed into the cavity of...
Gate Design Considerations: 1.Injection molding gate is a small opening between the runners and the mold cavity. their location, quantity, shape and size, etc. have a great influence on product appearance, dimensional , physical characteristics and production efficiency. 2.The gate size is dependent on product weight, material and gate types....
plastic resin material
In today's market, there are tons of material for customer to choose from. Therefore, The selection process of plastic injection molding material is very challenging at the beginning. At ECO Molding, we are well aware that each plastic material has its unique characteristics and advantages,...
Purpose of the Guiding system: Positioning & Guiding Maintain the correct clamping of the core and the cavity, as well as the correct shape of the cavity after clamping. Guide the mold core to be clamped in sequence, to prevent the core from being damaged...
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...
