Too much silicone oil is added in the process of making the mold, and the silicone oil destroys the molecular weight of the silica gel, so the mold will have fewer mold turns and not durable. If you are making...

Blow molding mold processing concept, blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin, while the plastic parison is heated to...

Conventional structure: 1. Two sets of mold embryos, the respective molding structures are more common: the front mold is the same, the rear mold is different (the second mold embryo is rotated 180 degrees). Note: There are certain techniques for...

Reasons for bad in plastic mold processing 1. Dent. The causes of dents are: 1) Insufficient cooling of the mold, insufficient cooling time will cause serious deformation. 2) This situation can also occur when the internal pressure of the mold...

In order to avoid unnecessary waste of time and trouble during mass production, it is indeed necessary to pay patience to adjust and control various processing conditions, find out the best temperature and pressure conditions, and formulate standard test procedures...

Advantages of domestic plastic mold factory industry development In view of the current situation, the development of the plastic mold industry indicates that the diffusion rate of industry-related knowledge will become more and more light. The knowledge points introduced below...

The order of disassembling and drawing the parts drawing from the general assembly drawing of the mold should be: first inside and then outside, first complicated and then simple, first forming parts, then structural parts. 1. Graph requirements: Must draw...

Under what conditions can the design of cooling water for plastic mold processing be met? 1. The water transportation margin and product material margin are generally not less than 10MM, and should be designed between 10MM-12MM as far as possible;...

The processing enterprise should test the various performances of the mold under the normal operation of the injection molding machine and the mold, and measure the size of the final molded plastic part.The existing state of the mold can be...

How much do you know about the entire plastic mold processing and design process? The first thing to consider is the finished plastic drawing and the analysis of the actual samples. At this point we have to consider the geometry,...
