Mold working conditions are complex, so the mold material must be resistant to high temperature, fatigue, wear resistance, not easy deformation. Aluminum alloy is currently the most widely used mold material. The mold made with it is light weight, hiệu suất xử lý tốt, high temperature resistance and wear resistance. The alloys commonly used as molds are 2 loạt, 5 loạt, 6 loạt, và 7 loạt, which can be used for underwear molds, shoe molds, Vân vân.

Common Aluminum Alloy Types for Molds

Các 2 series aluminum plate belongs to aluminum and copper alloy, is generally composed of 97% aluminum and 3% copper, hardness is very high, tensile strength, but generally not common. 5 series aluminum plate belongs to the aluminum magnesium alloy, the main characteristic is the rustproof performance is good, often used in the manufacture of mold alloy 5083 tấm nhôm, 5052 tấm nhôm. 6 series aluminum plate belongs to aluminum-magnesium-silicon alloy. It is one of the main materials for manufacturing high-end precision molds. It can be used for 80% of products in different mold industries such as injection molds, blow molds, low-pressure molds, and rubber molds. It is a commonly used mold aluminum plate. The T5 and T6 states of 6082 aluminum plate are suitable for molds with good machinability requirements. Nói chung là, the moulds are made of medium thick aluminum plate. The main alloying elements of 7-series aluminum plate are zinc and magnesium, which have a strong strengthening effect on the alloy. The tensile strength and yield strength of the alloy increase as the proportion increases. Đồng thời, 7-series aluminum plate is also an important material in aviation and aerospace industry.

Advantages of Aluminum Mold

1.Trọng lượng nhẹ, because its density is only 36% of general mold steel, so the motion inertia is relatively low, it is easier to increase and decrease the speed in the production process, which can reduce the loss of machinery and mold, and it is not easy to deform the mold.

2.Good processing performance, high dimensional stability, precise thickness tolerance, and reduced material waste. Its cutting speed is more than 6 times faster than general mold steel, which can save mold processing time and improve production efficiency.

3.Good thermal conductivity, can save the mold in the production of heating or cooling time, so as to improve the production efficiency.

4.Chống ăn mòn, oxidation resistance, easy to polish, and has a silver white luster, beautiful and durable.
