Matters Needing Attention When Using Die-Casting Mold Materials

Matters Needing Attention When Using Die-Casting Mold Materials The mold material should have good machinability and easy finishing; it has high heat treatment hardenability, which makes the internal and surface microstructure and properties after quenching uniform, and the dimensional deformation is small; durable high temperature plasticity and thermal fatigue resistance, The mold will not be…

Temper Brittleness Of Steel

Temper Brittleness Of Steel 1. Temper brittleness refers to the phenomenon that the toughness of the quenched steel decreases after tempering. When the quenched steel is tempered, the hardness decreases and the toughness increases as the tempering temperature increases. However, in the relationship between tempering temperature and impact toughness of many steels, two valleys appear,…

Mold Meets Process Performance Requirements

Mold Meets Process Performance Requirements Mold manufacturing generally involves several processes such as forging, cutting, and heat treatment. In order to ensure the quality of the mold and reduce the production cost, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and quenching. Deformation cracking…
