Due to the development of new technologies and aluminum molds, especially for the design of injection molds, aluminum molds are also more and more commonly used in the fields of blow molds, R.I.M. molds, rubber molds, structural foam molds, and R.T.M. molds. Although it may not be suitable for all applications, in fact, its use has become more and more common. Everyone hopes to extend the service life of the mold. For example, the mold is made of traditional tool steel, and the surface is plated with hard chromium or nickel metal, or a more specialized
General 3M double-sided adhesive wholesale customized 3M double-sided adhesive punching

3M9080 high-viscosity double-sided adhesive is a non-woven fabric substrate double-sided adhesive in 3M double-sided adhesive. It is made of double-sided non-woven fabric coated acrylic adhesive. It has good initial adhesion and holding viscosity, easy to die-cut processing, Good stability, good adhesion to plastic, rubber and rough surfaces; good holding power at high temperature. Long-term temperature resistance of 80℃, short-term temperature resistance of 120℃; to achieve better bonding effect, the bonding surface must be clean and dry. 3M9080 double-sided adhesive high-adhesive double-sided adhesive tape, good temperature resistance, firm, no trace, fast installation and fixed, beautifully fit. 3M9080 double-sided adhesive is widely used in the processing industry...

Due to the development of new technologies and aluminum molds, especially for the design of injection molds, aluminum molds are also more and more commonly used in the fields of blow molds, R.I.M. molds, rubber molds, structural foam molds, and R.T.M. molds. Although it may not be suitable for all applications, in fact, its use has become more and more common. Everyone hopes to prolong the production life of the mold. For example, the mold is made of traditional tool steel, and the surface is plated with hard chromium or nickel metal, or a more specialized engineering coating is used. This can prevent the surface from wearing or Corrosion promotes better demolding. Since then, in pursuit of the same goal, aluminum molds have been adopted and practical solutions have been found.

In order to be able to produce better decorative parts by injection molding, in addition to prolonging the service life of the mold, the manufacturer also hopes that the surface of the aluminum mold can maintain a certain degree of gloss, so it is recommended to use electroless nickel spraying 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 no surface coating is used, it is easy to be worn by plastics, accelerating the degree of damage, thereby changing the gloss of injection molded parts. The electroless nickel coating can increase the mold surface by 50RC, which is enough to protect and extend the gloss and structure of the mold surface. Electroless nickel coating can obtain better surface finish quality than aluminum itself, but it must be pointed out that some surface treatment is required before the mold can be electroplated. For example, in order to achieve the lens-level quality level, it is recommended to first process the surface of the aluminum mold to the SPIA-3 level of finish, and then apply 0.0003~0.0005 high phosphorus electroless nickel coating before it is further polished So that it reaches the diamond-quality finish level.
