First, the use of PVD nano-coating in injection molds

Injection molds because of the higher provisions, poor durability is more concerned. For example, the production of plastics containing glass fiber, very easy to damage the surface layer of the abrasive, or out of the mold must enhance the characteristics of wetting. pvd coating because of its unique wettability and high strength, can greatly improve the processing process encountered in the said problem.

Tin bronze is characterized by fast heat removal and a strength of “36-42 HRC” after heat treatment. Faster heat removal (three times faster than stainless steel sheet) means that injection molding cycle times can be reduced and production volumes higher. Tin bronze is more expensive than the usual plastic stainless steel sheet, so the cost of any damage, destruction or sharpening is very high. Since the strength of tin bronze is low, surface damage is a serious problem. Give full consideration to the strength and characteristics of tin bronze, coating enterprises very for the tin bronze stamping molds a set of sound PVD coating program TiN-BeCu, enhance the tin bronze surface wear resistance, in addition, but not easy to reduce the characteristics of its high heat transfer.

2、Precision machinery manufacturing

Injection mold parts of some raw materials selection of ultra-low temperature quenching and some parts of the appearance of the structure has easy to deformation characteristics, therefore, the choice of high temperature solution of the PVD coating scheme is not suitable. In this kind of situation, CrNC is a good choice, CrNC chemical corrosion resistance is strong, and its strength is not less than HV2000, can cope with the strength of the plastic manufacturing regulations, is a good choice for injection molds. And precision machinery manufacturing inserts are characterized by small dimensional tolerances, shape groove, to ensure that no deformation and the balance of the coating is not easy. Plating companies are well aware of the use of injection molds, and they use CrNC plating to deal with the problems of abrasive damage for their customers.

3. High-speed multi-concave mold mass production of abrasives

Transparent plastic bottles are typical of high speed multi-concave mold mass-production abrasives, and under high speed production conditions, the requirements for the surface layer are very high, such as high surface strength, polished to mirror glass, and excellent mold workability. Generally, manufacturers in Europe and the United States are willing to use Mirror-Gold PVD coating to improve the strength of the surface layer of the abrasives and to enhance the ability of wetting out the mold. Because of the high toughness of the PVD nano-coating and excellent wetting performance, thus reducing the production cycle, improve efficiency.

4, containing glass fiber high damage abrasives

Today's automotive companies are trying to find ways not to jeopardize the safety, quality of the situation, continue to reduce the total weight of the car, and thus achieve the goal of fuel efficiency. Rubber products are lightweight and high compressive strength, is an excellent raw material for automotive parts. However, if you encounter the production of rubber products such as polyester plus glass fiber goods, no matter what kind of mold steel, the surface damage is very strong. In order to increase the service life, general car manufacturers in Europe and the United States want to choose PVD coating. Wuxi City, a large and medium-sized automotive parts abrasives and product manufacturers to understand the benefits of PVD nano-coating, all of its manufacturing polyester automotive parts abrasives are selected PVD coating, which enhances the service life of the abrasives.
