Injection molding is only the processing of plastic products. If it is the production of prototypes, 3D printing and silicone molding are selected, but it will be used for mass production.

Explanation of injection molding knowledge

Mold temperature: The mold temperature has a great influence on the intrinsic performance and apparent quality of the product. The temperature of the mold depends on the crystallinity of the plastic, the size and structure of the product, performance requirements, and other process conditions (melt temperature, injection speed and injection pressure, molding cycle, etc.). Pressure…

China’s large-scale casting machine tool table industry technology level needs innovation

The large-scale casting machine tool workbench is an important point of development in our country at present, and it is also one of the standard lines to measure the level of China’s foundry industry. The large-scale casting machine tool workbench is to melt metal into a liquid that meets certain requirements and pour it into…

Suggestions related to precision mold injection and maintenance

Compared with other molds, injection molds have a more complex and precise structure, and have higher requirements for operation and maintenance of products. Therefore, in the entire production process, the use of positive solutions and careful maintenance and maintenance are very important to maintain the normal production of the enterprise and improve the efficiency of…

The important role of automation in mold production

By using the right combination of equipment and software, the efficiency is significantly improved. The automation system has the obvious advantage of increasing productivity, as much as two-thirds in some applications, while providing a more precise method to maintain inventory during this process In the meantime, they improve operational efficiency and productivity, reduce inventory levels,…

What are the requirements of the injection mold cavity positioning principle

The design of injection molded parts generally requires the design of the number and arrangement of mold cavities. The cavity of the mold cannot simply apply the dimensional tolerance of the mechanical parts. The dimensional accuracy of the plastic parts will be affected by many factors such as the structure of the plastic parts, the…

Problems and improvement measures of injection molding

Whether a set of injection molds are successfully opened depends mainly on whether the injection molds have a lot of problems? A successful set of molds can be reflected in product appearance, assembly, and production efficiency. Then, relatively speaking, the more injection mold molding problems, the greater the possibility that the mold is not opened…

Use of back pressure in the injection molding process

In the injection molding process, it will often be difficult to solve the shrinkage of a certain part of the product. In this case, only the back pressure can be solved by appropriately adjusting the back pressure parameters. The reason for using back pressure is that when the screw rotates, the heated plasticized plastic is…

What are the causes of dents in plastic mold processing

As a processing technology, plastic mold processing, after its production or completion, will be somewhat defective. How to solve this situation? 1. Dent. The causes of dents are: 1) Insufficient cooling of the mold, insufficient cooling time will cause serious deformation. 2) This situation also occurs when the internal pressure of the mold is insufficient….
