The metal materials of precision castings refer to materials with metallic characteristics, such as carbon steel, stainless steel, copper-aluminum composite materials, etc., which are essential materials for forging silica sol castings. The quality of metal materials largely determines the quality of silica sol castings. Let us look at the requirements of precision casting of metal materials.

First of all, the metal materials of the precision casting company mainly come from the materials purchased by the company, waste castings and risers. However, the purchased metal materials are usually in bulk and are rarely pressed into the cylinder. Materials of different materials are easily mixed together, such as 316 material and 304 or 430 material mixed together.

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

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