Precision castings have these requirements for materials

The metallic materials of precision castings refer to materials with metallic properties, such as carbon steel, stainless steel, copper-aluminum composite materials, etc., which are indispensable materials for forging silica sol castings. The quality of metallic materials largely determines the quality of silica sol castings. Let's take a look at the requirements for precision casting of metallic materials.
 

Firstly, the metal materials of the precision casting company mainly come from the materials purchased by the company, scrap castings and risers. However, the purchased metal materials are usually in bulk and rarely pressed into cylinders. Materials of different types can easily mix together, for instance, 316 material can be mixed with 304 or 430 material.

In addition, precision casting companies should choose to purchase materials that can be pressed into tubes as much as possible and use spectrum analyzers to analyze the chemical composition of each batch of purchased raw materials. If possible, the supplier should conduct on-site inspections to assess whether these materials have been marked, protected and stored separately.

Rust removal, degreasing, sand removal, cleaning and drying of the company's scrap steel (scrap castings, risers) are carried out to control the S and P components. In addition, scrap steel of different materials should be marked, protected, stored separately and not confused.
