CNC machined acetal parts Manufacturers

We should all be familiar with rubber and plastic products, but most people still don't know some professional knowledge. Let's take a look at the hazards of rubber and plastic products, so that everyone can use them better.

the plastic processing industry is quite vigorous, with the continuous progress of material technology, the injection molding process is now more and more mature, many manufacturers have been able to master this technology to produce and process plastics. In the middle of the injection molding process, the demand is often applied to a few molds, and the quality of the mold simply affects the quality of plastic products to some extent, so for the operator, the application of the tube mold is the basic requirement. What events do you need to pay attention to in the middle of the application process of injection molds?

In the production process of plastic products, injection molds can be described as an extremely important component. The quality of injection molds is not only directly related to the integrity of plastic products and the accuracy of dimensions, but also determines the production cost and economic benefits of enterprises, so the use of sophisticated modern technology to produce high-quality molds is particularly critical.

With the development of science and technology, plastic products have already become a kind of product that can not be replaced in our daily life. In real life, plastic products have almost occupied various categories. For example, in life, friends can see cars, boats, planes, computers, telephones and other few materials at any time, and a few of their plastic accessories are molded by plastic molds. When a product is born, it is necessary to open a mold, and we need to find a mold factory, often think that injection mold and plastic mold is the same meaning, hot ask about the difference between plastic mold and injection mold, please read this article, will take you to ask about the difference between!

Barrel temperature: The temperature that needs to be controlled during the injection molding process includes barrel temperature, nozzle temperature and mold temperature. The temperature of the first two passes mainly affects the plasticization and activity of the plastic, while the latter temperature mainly affects the activity and cooling of the plastic. Each kind of plastic has a different activity temperature, the uniform plastic, because of the source or grade difference, its activity temperature and differentiation temperature are different, this is because of the equilibrium molecular weight and molecular weight dispersion difference, the plasticization process of the plastic in the injection machine of the different example is also different, so the temperature of the selected barrel is not similar.

Generally speaking, plastics have large crystallinity, small polarity or non-polarity, and low surface energy, which will affect the adhesion of the coating. Since plastic is a non-conductive insulator, it cannot be directly coated on the surface of the plastic according to the electroplating process regulations. Therefore, before the surface treatment, the necessary pretreatment should be carried out to improve the adhesion of the coating and provide a conductive bottom layer with good adhesion to the coating.
