What is the injection molding mold? The injection molding mold production process- Dunhai Mould Factory

Injection molding and blow molding are the two production processes of mold products, but their production processes are different and their styles are very different. To put it simply, the injection molding mold uses the "injection pressure" method, and the blow molding mold uses the "injection blow" method. In addition, the injection molding process uses solid activated carbon fibers, while the blow molding uses empty activated carbon fibers. In addition, the mold made by injection molding has a cross-section of the glue inlet, and the surface of the mold made by the blow molding process is not flat and contains a blowing inspection port. Below I will take everyone to understand in detail what is an injection mold and what is a blow mold? What is the difference between each other?

1. Injection mould Injection molding is thermosetting plastic injection molding. This type of method is to melt the plastic raw material and then introduce it into the film cavity. Once the molten plastic enters the mold, it will be cold-formed and processed into the desired shape. Moreover, the appearance of his personal income is usually the final finished product, and no other production and processing are necessary. In addition, the injection mold processing technology can control key points very well, such as Protrusions, ribs, external threads and other positions can be formed in one step in the injection of rubber and plastic products.

2. Blow mold Blow molding, also known as hollow blow molding, is a fast-developing plastic production and processing method. The basic principle of its production and processing is as follows: place the thermoplastic plastic or the tube-shaped plastic parison obtained by injection molding in the mold, and then introduce air compression after the mold is closed to inflate and tighten the plastic parison. Stick it on the inner cavity of the mold, and then cool out of the mold to finally obtain the desired hollow product. It is worth mentioning that the basic principle of the manufacturing process of blown plastic film is very similar to that of hollow product blow molding, but its manufacturing does not use molds, which is completely different from processing injection molds. From the perspective of the technical classification of plastic production and processing, the forming process of blown plastic film is generally included in the extrusion process. According to the practice of parison, blow molding can be divided into extrusion blow molding and injection blow molding. The newly developed two-layer blow molding and stretch blow molding.

3. The difference between injection mold and blow mold According to the detailed introduction, I firmly believe that everyone has a certain grasp of these two production processes. In fact, the key difference between the injection mold and the blow mold depends on the way the product is displayed. The products made by the injection mold processing technology are generally thicker, relatively easy to make, and the raw material requirements are relatively low. The blow molding process is different. The finished product is thinner and completely transparent, and it is very easy to see the slight defects. It is precisely because of that, so the blow mold production and processing requirements are relatively high, and the raw materials are stretched.

There are certain regulations on sex and resilience. Injection moulds and blow moulds are commonly used in daily life, and they have their own characteristics and advantages. Their production processes are also gradually developing, and they will have a good future for development in the future.
