According to relevant department statistics, the import and export scale of China's mold industry has reached 4 billion U.S. dollars, of which the level of imports and exports are equivalent, both are about 2 billion U.S. dollars. China's mold industry is in a rapid development path.

There is an interesting question in the mold industry: How to extend the service life of aluminum molds so that they can be applied to limited production? Using aluminum as a more cost-effective method to produce a mold has many advantages. The cycle time of mold making is shortened, thus reducing the production cost. In addition, the mold has better thermal conductivity, which means that the production cycle can be greatly shortened.
Everyone wants to be able to extend the production life of molds, such as using traditional tool steel to make molds, using hard chrome or nickel metal plating on their surfaces, or using more specialized engineered coatings to prevent their surface wear or Corrosion promotes better mold release. Since then, in order to seek the same goal, began using aluminum molds and found a practical solution.

In order to be able to produce injection molding to produce better decorative parts, in addition to extending the life of the mold, the manufacturer also hopes that the aluminum mold surface can maintain a certain degree of gloss, so it is recommended to use the electroless nickel spray process, because This method helps to extend the life of the mold surface finish, making it relatively easy to produce decorative parts.

Due to the soft texture of aluminum, if you do not use a surface coating, it is easy to be worn by the plastic and accelerate its damage, thus changing the gloss of injection molded parts. The electroless nickel coating can increase the surface of the mold by 50RC, making it sufficient to protect and extend the gloss and structure of the mold surface. The electroless nickel coating can achieve better surface finish quality than the aluminum material itself, but it must be pointed out that before the mold can be electroplated, some surface treatment is first required. For example, to enable it to achieve a lens-level quality level, it is recommended that the surface of the aluminum mold be first machined to a SPIA-3 finish level, and then apply a high phosphorous electroless nickel plating coating of 0.0003 to 0.0005 before further polishing. , to achieve diamond-quality finish levels.

The trend of long-term use of aluminum molds for injection molding production will continue, and no doubt will also develop a series of more innovative aluminum alloy materials to meet and meet the needs of different mold production and application. Regardless of what happens when this principle is followed, there is always an engineering coating that can be used to improve the quality of the product and extend the life of the mold. This is a very simple matter. Dealers who provide plating services have a lot of experience. And resources can help people to achieve this desire. (This site edits Fei)
