mold assembly shop
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...
injection mold cooling system
Influence of Injection Mold Cooling 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...
three plates mold structure
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...
air bubbles injection molding defects
01. Silver Mark As a matter of fact, this injection molding defects usually happens because the raw material is not dried. It occurs mostly during the T0 stage of a product, while in the subsequent regular production stage, such a defect is rarely caused. 02. Welding...
jetting plastic injection molding defects
(1) What is jetting? (Appearance) Usually, the molten resin flows in the form of a jet stream. However, when flowing from a narrow area to a wide space, if too fast, it sometimes flies out in strips, and flows without contacting the mold. This is referred to as jetting. Depending on the appearance of the jetting...
