There are many requirements for the materials on the Air Cooler Mould(FURNITUREMOULD). Today we have come to understand the requirements of the air cooler mould.

Having sufficient surface hardness and wear resistance: the general hardness of the air cooler mould is usually below 50-60HRC. After heat treatment, the air cooler mould shall have sufficient surface hardness to ensure sufficient rigidity of the air cooler mould. The air cooler mould is subject to large compressive stress and friction due to the filled and flowing plastic during operation, which requires the air cooler mould to maintain the stability of its shape accuracy and dimensional accuracy, so as to ensure sufficient service life of the mould. Wear resistance of air cooler die depends on chemical composition and heat treatment hardness of steel, so the increasing hardness of die is beneficial to improving wear resistance.

Excellent machinability: Most air cooler mould require a certain degree of cutting and fitter repair in addition to EMD processing. In order to prolong the service life of cutting tools, improve cutting performance and reduce surface roughness, the hardness of air cooler dies steel must be appropriate.

Good polishing performance: high-quality plastic products with small surface roughness. For example, the surface roughness value of the injection mould cavity is less than Ra0.1. At the level of 0.25, the optical surface needs Ra <0.01nm, and the cavity must be polished to reduce the surface roughness value. The steel used for this purpose requires fewer material impurities, fine and uniform structure, no fiber direction, and no pitting or orange peel-like defects during polishing.

Good thermal stability: the shape of air cooler mould parts is often complicated and difficult to process after quenching. good thermal stability should be used as far as possible. when the air cooler mould is processed and heat-treated, due to small linear expansion coefficient and small heat treatment deformation, due to small size change rate and stable metallographic structure and mould size, the temperature difference that can be reduced or no longer processed can be reduced, and the requirements of air cooler mould size accuracy and surface roughness can be ensured.
