In the injection molding products injection molding products are air bubbles is a lot of people in the problems in production and processing, in general, some of the reasons for such problems, but if cannot be handled timely, will not only make plastic molding bad, also may produce more defects, so, when in injection molding products are air bubbles, must be timely solve.
As you all know, plastic mold design is the one of the most important link in the process of plastic mold manufacturing, mould manufacturing is forward, directly affect the plastic mould manufacturing quality and cost, detail decides success or failure, our precision mould design engineer after many years of experience in mold design, plastic injection mold design to summarize some points for attention.
All the plastic mold designers know that in the injection molding production process of plastic mold, there are many ways to make the product out of the ejection, among which the most commonly used and most economical is the ejection of the thimble to separate the plastic product from the mold. The position and number of ejection thimble of plastic mold products are generally determined according to the structure of the product.
In today\'s era of rapid development of industrialization, plastic moulds have become an indispensable part of the industrial age. So today we are going to talk about the surface treatment commonly used in injection molds.
Plastic mold processing from plastic into the mold in addition to through the heat radiation, the heat flow out of the mold. Most of the heat is carried out of the mold by means of heat conduction by circulating heat transfer medium. Heat transfer medium includes water, oil, etc.
In the processing of die products, what are the reasons for the large surface roughness and lack of gloss? Below our factory from the mold processing equipment, injection mold, plastic mold, mold processing technology and raw materials to give you a good analysis.
In the production process of injection molds, polishing is a very important process in the production process. After all, with the increasing use of plastic products, people will also have higher and higher requirements for the appearance and quality of plastic products. Therefore, for our injection molds The surface polishing quality of the cavity should also be improved accordingly, so let\'s take a look at several common polishing methods in injection molds!
1. Structural design should be reasonable, assembly should be reasonable, all plug-in structure should have clearance, to ensure enough strength and stiffness. And properly designed reasonable safety factor.
2. The structural design of plastic parts should consider the manufacturability of molds and simplify the manufacturing of molds as far as possible.
3. The structure of plastic parts should consider the plasticity, that is, the injection molding production efficiency of parts should be high, and the waste rate of injection molding should be reduced as far as possible.
Mold, a variety of molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make a molded object. This tool is made up of various parts, and different molds are made up of different parts. It is mainly through the change of the physical state of the forming material to achieve the processing of the shape of goods, known as the \"mother of industry\" title.
