The die casting industry is changing with each passing day, and the technological innovation has never stopped. In the field of OEM Aluminum Enclosure, there is such a technology that OEM aluminum enclosure is combined with dissimilar materials. Have you heard of it?

The connection technology of dissimilar materials has no glue in OEM aluminum enclosure and does not need to be installed in the connection technology of dissimilar materials which are strongly combined together. Its application type is material growth. In improving OEM aluminum enclosure materials, this technology is expected to be quickly used to cast more cars. The principle is that some small holes are opened on the metal surface, and molten resin is poured. If the resin is cooled and solidified, the resin anchor hook hole cannot be pulled out. The bonding process is mainly divided into the following three steps:

The first step, dip metal degreasing liquid to remove the oil attached to metalworking, rust on the surface, etc.

In the second step, the surface of the metal etching solution is coarsened to make the metal surface coarsen and form some tiny holes. Then dip the metal in acidic solution, develop the precipitation of by-product (waste) on the metal surface, wash it with water, and dry it.

And thirdly, performing injection molding, resin transfer molding and extrusion molding on the hole surface of molten metal resin. After solidification, the resin consists of resin and metal joint.
