Injection molds are often burned for some reason during production.Depending on the cause of the burn, such as machine, mold, or molding conditions, there are different solution. 1. Mechanical reasons: overheating of the cylinder due to abnormal conditions; or stagnation of the resin due to the nozzle and screw thread.At this time, the nozzle, screw and barrel should be cleaned. 2. The cause of th...

Mold Definition and Classification Mold is called “Mother of Industry”. It is a processing tool that processes raw materials and gives raw materials a complete configuration and precise size. It is mainly used for efficient and high-volume production of related parts in industrial products. The development of the mold industry has always been valued by the state. According to the National Developm...

To make high quality mirror polishing on mold (cavity and core inserts, same as below), the requirement of mold surface polishing of mold is high, because this is the most important loop of mold manufacturing.  The surface with roughness and corrugated grain is an abnormal phenomena in mirror polishing of molds. Generally, it is the the mold steel material, the polishing method, or the inject...

During the production of injection, some products are not easy to demould.  Therefore, there is a push-rod release mechanism at the time of mold design.  The push rod demoulding device is simple structure, convenient manufacture and replacement, small sliding resistance and flexible demoulding position, and is the most commonly used structural form in the demolding mechanism.  Howev...

Everyone in the mold industry knows that pc injection molds will encounter some quality problems in one or the other during injection molding. Why do the same set of molds have different effects on products with different materials?  This is due to the difference in the performance of the PC injection mold and the plastic material used for the injection molding. The pc material is relatively ...

The plastic injection mold is consist of several steel plates with different components. Basicly it's divided into below parts: A Forming unit（cavity，core） B Locating device（guide pin，guide bushing） C Fixed device（top clamp plate, clamp slot） D Cooling system（water line, water tube） E Constant temperature system（heating tube，heating element） F Runner system（sprue nozzle，flow channel slot，runner ho...
