Netizens in the 293rd live broadcast room asked, what is the corrosion-resistant mold material for nylon GF50?
The reinforced plastic of injection molded nylon and glass fiber GF50 contains a large amount of glass fiber, which causes severe erosion to the mold. The mold steel must have high hardness, high wear resistance, and non stick properties to resist the erosion of 50% glass fiber nylon material on the mold. Otherwise, the mold will be quickly eaten up, causing the product to become sharp. Based on past experience, I recommend non stick 8503 die steel.
8503 is a non stick die steel with a proprietary alloy ratio for Wu Dejian tool steel. It has a hardness of 55-61HRC and a fracture resistance twice that of DC53. However, compared with DC53, its performance doubles, the price does not double, and it also has the advantage of non stick material. Especially the non stick properties of this material, combined with its high hardness, are the fundamental and effective solution to solve the problem of molds with too much glass fiber being easily eaten, causing the product to run out of shape, and the mold to become rough.
Mr. Li’s mold is made of reinforced plastic with injection molded nylon and 30% fiberglass. The product has a reverse buckle structure, which causes severe damage to the mold. Now, it is hardened with S136 quenching, and the mold is almost pulled out into pits. But using non stick 8503 die steel for a year and a half, there was no feeling of strain.
And the netizen added 50% glass fiber nylon material, which has more severe erosion on the mold, and requires the use of non stick material 8503. As Mr. Yu from Ningbo said, the mold for adding fiberglass is made of 8503 die steel, which is quite nice. It can be pressed continuously without any sharp edges!
