What are the ways of surface treatment of aluminum mold?

Compared with iron mold, because of the low hardness of aluminum, methods like sandblasting are not suitable for aluminum mold. If the aluminum mold is sandblasted, the sharp edges of the iron sand will form a trace on the surface of the mold, making the surface of the product easy to produce pulling strains, which will destroy the beauty of the product surface. There are also etching patterns, also not very suitable for casting aluminum mold used. At present, the commonly used aluminum mold surface treatment methods are as follows.

    1、Mirror polishing: This method is suitable for high-end rotomolding products with high standard requirements on appearance. The advantage is that the products are easy to take off, the mold line is fine, the surface is bright and smooth, the flow line is smooth and smooth, and the products give people a high grade feeling. The disadvantage is that the production cost is high, the production time is long, the products are easy to deformation, the surface is easy to scratch.

    2, shot blasting: this method is the first choice for rotomolding shaped parts products, also suitable for the pursuit of characteristics, personality and beautiful and beautiful products. The advantages are that it can effectively control the deformation of the product, help the product surface exhaust, reduce the porosity of the product, the product is not easy to scratch, beautiful appearance, and easy to repair. The disadvantage is that the surface of the mold is easily dirty and needs to be cleaned regularly.
