Your task is to check whether the factory has established a systematic and effective incoming material or components quality control system.Ask your factory representative to take you to the incoming area to observe the Q.C. staff conducting the incoming inspection. Secondly, rejected materials and components. If they try to tell you that they do not have any rejected materials or components, you can be sure that the Q.C. staff is either not being thorough enough or they are lying and they don't have an incoming Q.C. process.

2018-04-09

custom plastic injection moldAs a china plastic injection mold company, PTMS have much experience in plastic injection mold making, so we can make high quality custom plastic injection mold as customers’ request, as a plastic injection moulders, we would like to share other elements of plastic injection mold for the worldwide people.


The rest injection mold elements as below.


Core back plate. It holds the core insert in place and acts as a "stiffener". It is usually made of mild steel.

Guide pillar and guide bush. The guide pillar and guide bush align the fixed and moving halves of a mold in each cycle. The material cases are usually made of medium carbon steel and will have higher hardness.

Ejector guide pillar and guide bush. These components ensure the alignment of the ejector assembly so that the ejector pins are not damaged. They are usually made of CHMCS. The guide pillar typically has higher hardness than the guide bush.

Ejector plate. This holds the ejector pins and is usually made of mild steel.

Ejector back plate. It prevents the ejector pins from disengaging; usually of mild steel material.

Heel blocks. Provides a gap for the ejector assembly, so that the finished component ejects from the core. Usually made of mild steel.

Bottom plate. Clamps the bottom half of the mold with the fixed half of the molding machine; usually made of mild steel.

Centering bush. Provides alignment between the bottom plate and the core back plate; usually made of CHMCS.

Rest button. Supports the ejection assembly and reduces the area of contact between the ejection assembly and the bottom plate. It is most helpful when cleaning the injection molding machine, which is essential to ensure an "unmarked" finished component. Small foreign particles sticking to the bottom plate may cause ejection pins to project out from the core and result in ejection pin marks on the component.
