Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. to obtain the desired products. In short, a mold is a tool used to form an article, and the shape of the article is processed mainly by a change in the physical state of the formed material.
The mold has a specific contour or cavity shape. It is a precision tool with complex shape and bearing the expansion force of the blank. It has high requirements on structural strength, stiffness, surface hardness, surface roughness and machining accuracy.


At present, the materials for manufacturing molds on the market include steel, hard alloy, zinc-based alloy, aluminum alloy, and polymer materials. Compared with other materials, aluminum alloy molds plate have obvious advantages such as light weight, good processing performance, high temperature resistance and good wear resistance, so they are used in 80% of different mold industries such as injection molds, blow molds, low pressure molds and rubber molds are widely used. With the development of the market, super-hard aluminum alloy mold plate has been basically used as a substitute for steel in the European and American markets.
Chinalco is an annual production capacity of 100,000 tons. The aluminum alloy plates produced by Chinalco for mold manufacturing include 6061 precision mold aluminum plate, 6082 precision mold aluminum plate, 7075 precision mold aluminum plate, 7475 precision mold aluminum plate, 7050 precision mold aluminum plate, etc., which have good forming and processing properties. With the trend of mold manufacturing in the international market using super-hard aluminum alloy, the high-quality super-hard alloy aluminum plate produced by Chinalco will successfully enter the mold manufacturing field.
