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....
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,...
When industrial products are developing towards diversification and high quality, it is an important task to improve the quality of the molds that directly affect product quality. During mold manufacturing, smooth mirror finishing after shaping, referred to as surface grinding and polishing of a part, is an important process step to improve...
The chemical and physical properties of PA6 are similar to those of PA66, but the former has a low melting point and a wide process temperature range. While featuring better impact and solvent resistance than PA66, it is also more hygroscopic. Since many of the characteristics of a plastic product are affected by hygroscopicity, this should be...
Plastic injection mold assembly constitutes one of the most important post-processes during injection mold manufacturing, since mold quality is closely related to assembly. Mold parts go through such processes as milling, drilling, grinding, CNC and EDM, and after passing inspection, emphasis is placed on the assembly process. The quality of assembly directly affects the quality of the...

Influence on Product Quality
Surface Gloss: Many materials require a relatively high mold surface temperature to achieve a great surface gloss in production. If the cavity temperature is different between some areas and others, a different surface...
A three-plate mold has three partings – the first is between the runner plate and the cavity plate, the second between the runner plate and the top clamping plate, and the third between the cavity plate and core plate.
1. In the beginning, when the core is subjected to...
