1. When using forming plastic molds, CNC punching machines are strictly forbidden to punch without plates, and the molds cannot be empty. At the same time, the tightness of the locking screws must be checked frequently, otherwise it will easily...

According to different molding methods, plastic mold processing mold types corresponding to different process requirements can be divided, mainly including injection molding molds, extrusion molding molds, plastic molding molds, high-foam polystyrene molding molds, etc. 1. Plastic injection (plastic) mold It...

What structural factors and parameters are needed when designing plastic molds 1. Parting surface, that is, the contact surface between the concave mold and the convex mold when the mold is closed. The choice of its location and form is...

Materials are very important for plastic molds.When selecting materials, molds must be selected according to the conditions of mold production and working conditions.The mold materials must meet five performance requirements: wear resistance, toughness, hardness, red hardness and processing The main...

Various parts on the processing of plastic molds should have sufficient strength and rigidity to prevent damage and deformation during use, and fastening parts must have anti-loosening measures to avoid accidental injury to the operator. The structure should try to...

First of all, we must understand why the plastic mold has the problem of difficulty in demoulding. 1 The groove is formed in the mold; 2 The mold release slope is insufficient; 3 The mold finish is not high. The...

For large-scale household appliances precision plastic mold products with high surface quality requirements, shrinkage is a big problem. It can be said that this is a major enemy facing plastic mold processors. For this reason, people have developed various technologies...

In the development of plastic molds, in order to better manufacture parts and workpieces, we choose the most suitable molding method, which can not only improve the service life of the mold, but also greatly help the use of workpieces....

The exhaust grooves of plastic molds are often set in two stages. The first-level exhaust slots are mainly airtight plastics that only discharge air, while the second-level exhaust slots are often deeper to facilitate rapid exhaust of gas. The most...

In the process of plastic mold processing, cracks or deformation, easy oxidation and decarburization of the surface are mainly due to the failure of the mold. The reason for the failure of the plastic mold is mainly due to the...
