In mold manufacturing, these processing points must be controlled in place

In the production process of modern products, the existence of processing tools such as molds can bring more convenience to the whole production process and improve the quality of the products produced. It can be seen that whether the mold processing is standard or not will directly determine the quality qualification rate of subsequent products. Therefore, when purchasing molds, we must choose molds with higher accuracy, so that the qualified rate of processed products can become better.
If you want […]

② Check and clean […]

What is the structure of the injection mold?

The plastic mold is composed of a moving mold and a fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form the gating system and cavity. When opening the mold, the moving mold and the fixed mold are separated to take out the plastic […]

What if the injection molded products are burnt during injection molding?

Scorch marks refer to the phenomenon of blackening at the end of the flow because the gas in the mold cavity cannot be discharged in time.
Causes of coke marks:
1. The cavity air cannot be discharged in time
2. Material degradation
a. Excessive melt temperature
b. Too fast screw speed
c. Improper design of runner system
Improvement method:
1. Mold design
a. Add an exhaust system where poor exhaust is easy to occur
b. Increase the size of sprue, shunt and gate
2. Process conditions
a. Reduce injection pressure
b. Reduce […]

Hardness: an important performance index of mold materials and finished molds

In industrial production, mold steel is the main material of the die industry. The service life of the die and the accuracy, quality and appearance performance of the finished parts are not only related to the design technology and manufacturing accuracy of the die, but also related to the accuracy and manufacturing operation of the machine tool. Correct selection of die materials and correct execution of heat treatment process are also crucial. The heat treatment quality and service performance […]

Standards for mirror polishing of mold, methods and precautions for mold polishing

Polishing is a very important process in the process of making plastic molds. Generally, it is a process of polishing the mold cavity surface with oilstone, sandpaper, polishing paste, etc., so that the working surface of the mold can be as bright as a mirror.
Mold polishing can make the surface of the product smooth and beautiful. In addition, it can make the product easier to demould on the mold.
The standards for mirror polishing of molds are divided into four […]
