The production process is basically the same, powder mixing-molding-sintering-post-treatment-inspection-packaging, but the process parameters will be different.
Iron-based forming is a process that meets certain size requirements or surface requirements. Because the forming elasticity of iron-based products has great aftereffect, the dimensions of general products change greatly after forming and sintering. The outer diameter, inner diameter or height of the same batch may not meet the requirements of the final product, and then the molding process is designed to meet the requirements of size and height. Generally used for products with tight tolerance requirements.
Powder mixing is mainly related to the particle size, size and shape of powder, as well as alloying elements, lubricants and binders.
Forming is the tonnage of the press, the design of the mold, and other related.
Sintering is related process parameters such as sintering temperature, sintering atmosphere or sintering time.
Then some post-treatment, machining, heat treatment (quenching, tempering, etc. ) and surface carburization.
