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….

What are the characteristics of precision injection processing molds ?

1. Wear resistance When the blank is plastically deformed in the mold cavity, it moves and slides along the outside of the cavity, which causes intense friction between the outside of the cavity and the blank, thereby inducing the mold to take effect due to wear. Therefore, the wear resistance of the material is one…

Main influencing factors of various failures of precision injection molding

The basis for determining precision injection molding is the accuracy of the injection molded product, that is, the dimensional tolerance, shape tolerance and surface roughness of the product. There are many relevant conditions for precision injection molding, and the most essential are the four basic factors of plastic materials, injection molds, injection molding process and…

How to reduce defects in engineering plastic products mold processing

1. Reasonable use of cooling lubricant, play the three major roles of cooling, washing and lubrication, keep cooling and lubrication clean, so as to control the grinding heat within the allowable range to prevent thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as the use of oil-immersed grinding wheels or internal…

Analysis of the reasons that affect mold precision injection processing

The mold designer must have rich design and injection molding experience. For precision mold processing, the relationship between these influencing factors and the injection conditions and their apparent factors must be considered, such as injection pressure and cavity pressure and filling speed, injection melt temperature And mold temperature, mold structure and gate form and distribution,…
