Stainless steel casting is called investment casting or stainless steel precision casting. It is a casting process with little or no cutting, and it is an excellent process technology in the foundry industry.

The current status problems of stainless steel casting are described as follows:

1. Serious environmental pollution and harsh working environment

The charge in foundry production is mainly pig iron, scrap steel, coke, limestone, etc., molding sand and core sand. Mainly transportation, sand mixing, modeling, core making, baking, melting, pouring, cooling, falling sand, cleaning and post-processing of raw sand, clay, coal powder, resin and other binders, curing agents, old sand, etc. As far as the work content is concerned, the process is carried out under mechanical vibration and noise, and some are still at high temperature, such as melting and pouring, and some produce pungent odors, and the dust working environment is even worse.

2. Low technological level and poor casting quality

The design of the gating system is unreasonable. Due to improper design, there are defects such as entrainment and inclusions, resulting in low casting yield and qualification rate.

3. High energy consumption and raw material consumption

The current status of stainless steel precision casting technology, some problems we can solve must be solved in time, objective problems, we can not solve, there is no way.
