Low Volume Manufacturing Service | China Plastic Injection Molding Companies With Tooling And Injection Moulding Die Makers

Low volume manufacturing is a specialized service offering full production-quality parts but in volumes usually limited to 100,000 pieces or fewer, depending on the process used. This is an increasingly popular option for many product categories, allowing for a more limited investment in tooling and materials while providing quick access to markets, rapid response to shorter product life cycles and as a bridge between initial prototypes and high-volume production.

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 […]

Several characteristics of precision mold processing

The most important thing in precision mold processing is precision. Therefore, the size of the workpiece has high requirements, and the error is about +-0.005. In addition, many precision molds cannot have a slope during production. It is precisely because of the operability and controllability of processing that the whole process can be carried out smoothly. Here are some features of precision mold processing.
1. Abrasion resistance
When plastic deformation occurs in the female mold of the injection mold, the raw […]

What is the to reduce the use time of precision mold processing?

What are the factors affecting the service life of precision mold processing? Here, Dj molding has sorted out some contents for you. Come and have a look.
1、 The main factor is corrosion failure. When the mold hardness is high, the corrosion resistance is good. If the die hardness is poor, the corrosion resistance is poor.
2、 Thermal fatigue crack damage failure, injection molding and mold are formed repeatedly under the action of cold and heat to form surface and internal […]
