금형 작업 조건이 복잡합니다., 따라서 금형 재료는 고온에 강해야합니다., 피로, 내마모성, 쉽지 않은 변형. 알루미늄 합금은 현재 가장 널리 사용되는 금형 재료입니다.. 그것으로 만든 금형은 경량입니다, 좋은 처리 성능, 고온 저항 및 내마모성. 일반적으로 금형으로 사용되는 합금은 다음과 같습니다. 2 시리즈, 5 시리즈, 6 시리즈, 과 7 시리즈, which can be used for underwear molds, shoe molds, 등.

Common Aluminum Alloy Types for Molds

그만큼 2 series aluminum plate belongs to aluminum and copper alloy, is generally composed of 97% aluminum and 3% 구리, 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 알루미늄 판, 5052 알루미늄 판. 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. 일반적으로, 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. 동시에, 7-series aluminum plate is also an important material in aviation and aerospace industry.

Advantages of Aluminum Mold

1.가벼운 무게, 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.내식성, oxidation resistance, easy to polish, and has a silver white luster, beautiful and durable.
