Cixi Zonghan Jingxin Mold Factory was founded in 2005, is now located in Cixi City, Zhejiang Province, Chaotang Industrial zone, the company covers an area of 4000 square meters, more than 3000 square meters of modern plant, mold manufacturing and processing equipment more than 10 sets, punching equipment 20 sets, projectors 2 sets, wire cutting 12 sets.　

First, hardware surface polishing Polishing is widely used in everyday products, especially on products prone to pilling and burring. It can not only maintain the appearance of the product, but also allow users to have a better experience. Polishing is divided into mechanical polishing, chemical polishing and electrolytic polishing.　

Stamping parts in the production process due to punching force, die design, material quality caused stamping parts finished corners or corners cracking. To prevent the occurrence of such phenomena, it is necessary to develop a strict material testing system, a standard production process, and a mold maintenance system.　

In the production process of stamping parts, there is a precision and efficient long-life mold, and in the long-term mechanical movement of stamping forming, the mold will inevitably have problems for different reasons, which leads to the poor production of stamping parts. The corresponding maintenance system process is established to ensure that the mold is kept in good condition during storage and production, and to ensure the quality of stamping parts.　

The design structure of stamping die is directly related to the production accuracy and quality of stamping parts. However, in the process of stamping parts production, it is not only necessary to ensure the precision and quality of the finished products of stamping parts, but also to pay attention to the safety of personnel in the production process.　

If all are blanking punch, can be the same length, can also be different length. The same long benefit is that when repairing the cutting edge of the mold, it is better than the grinding force, and it can be finished once in the flat grinding. The advantage of different punch length is that the punching force can be reduced, so that the tonnage of the original punching machine is not enough, and the parts that can not be stamped can also be stamped.　

On a set of cold stamping die, only one process is a single process die. For example: single punching, single blanking, single stretching, single bending; On a set of cold stamping die, a stamping, punching, blanking, or punching, blanking, drawing, bending and other multi-process cold stamping die is called progressive die.　

Just a few points for you 1. Whether the opening and closing of the injection mold are smooth. 2. Whether the mold is smooth. 3. The gate location and feeding method of the injection mold, as well as the size of the gate and the size of the cavity, choose the appropriate pressure, speed and quantity.　

Hardness: the size and shape accuracy of the guide column and guide sleeve above HRC58 are strictly controlled within 0.003mm; In particular, the boiling density of the steel ball in the steel ball cage is 1.7 times that of the ordinary steel ball cage, so that the point war of the guide column and guide sleeve through the steel ball is increased by 70%.
