Will composite mold impact metal mold?

Recently, powder metallurgy composites have been widely used in the aerospace field, with high strength, small thermal expansion and flexible designability. Therefore, they have become one of the four major structural materials for aerospace. Will the composite mold impact the metal mold? The following is the introduction of Xiaobian zhongwei.

1： What are the advantages of composite mold?

1: Low material density

Because carbon fiber composites have the characteristics of high strength, high modulus and low density, the thickness of the molding surface made of carbon fiber composites can be very thin, generally only about 6 mm, and the maximum thickness will not exceed 9 mm. Therefore, even for large and complex composite mold, its weight is very light, easy to carry and easy to use.

2: Low temperature curing and high temperature use

At present, the mold prepreg can be cured at 60 ℃ or even lower. After leaving the master mold, the mold can be used at high temperature after post-curing in a free state.

3: Relatively low cost

The manufacturing cost of composite material mold is still much higher than that of steel mold and aluminum alloy mold, but it is lower than that of INVAR alloy mold, especially when the mold shape is more complex and the number of molds required is more, the cost will be lower.

4: Low thermal expansion coefficient

The biggest advantage of the composite mold is that the coefficient of thermal expansion is small, and it matches the coefficient of thermal expansion of the composite material. In this way, the appearance accuracy and dimensional accuracy of the part can be obtained. How does it compare with the performance of the powder metallurgy mim injection molding?

5: Less heat required

When heating and curing the composite mold, the heat required is relatively small, and the specific heat capacity of carbon fiber composite is generally greater than that of metal materials. Because the mass of composite mold is lighter than that of metal material, it can be heated and solidified at a relatively fast heating rate as required, and the curing of composite components can be completed in a relatively short curing cycle.

6: Good repairability

The composite mold can be repaired in a short time and at a low cost when suffering from impact damage, vacuum leakage, surface scratch and other problems.

To sum up, the answer that the composite mold will impact the metal mold has been told to you. You need to know more about it. Please pay attention to the zhongwei precision official website.
