Main Factors Affecting Hardness of Crate Mould


With the development of industry, industrial production […]

With the development of industry, industrial production and people's life cannot be separated from the use of moulds. As an important part of moulds, mould accessories are closely related to moulds. The wear resistance of Crate Mould affects the hardness of die parts. In general, the higher the hardness of crate mould, the smaller the wear amount, and the better the wear resistance. Let's talk about it in detail.

1. Strong patience

Most of the working conditions of crate mould are very harsh, some of which often bear large impact load and then lead to brittle cracking. In order to avoid sudden brittle fracture of mould parts during operation, the crate mould must have higher strength and patience. The tolerance of crate mould depends primarily on the carbon content, grain size and arrangement status of the data.

2. Wear resistance

When the blank plastically deforms in the mould cavity, it moves and slides along the outer surface of the mould cavity, causing severe friction between the outer surface of the mould cavity and the blank, and then causing the mould to fail due to wear. Therefore, the wear resistance of the data is one of the most basic and important functions of the mould.

3. Fatigue and cracking function

In the process of operation, the long-term effect of cyclic stress often leads to fatigue and cracking of crate mould. It takes the form of repeated impact fatigue cracking, tensile fatigue cracking, contact fatigue cracking and zigzag fatigue cracking with small energy.
