What is Heat treatment

Heat treatment refers to a metal thermal processing process in which the material is in a solid state by means of heating, heat preservation and cooling to obtain the expected structure and properties. In the process from the Stone Age to the Bronze Age and Iron Age, the role of heat treatment is... Read More

Precision casting

Precision casting can also be divided into gravity casting and pressure casting according to the pouring process of molten metal. Gravity casting refers to the process of pouring molten metal into a mold under the action of the earth’s gravity, also known as casting. Gravity casting include... Read More

Water glass precision casting

The process of sodium silicate shell has been produced for nearly 50 years in China. Through the unremitting efforts of colleagues in the investment casting industry for half a century, the application and research of sodium silicate shell process have reached a very high level. Over the years, t... Read More

Bending Process

Bending is a stamping process that uses pressure to force a material to plastically deform to form a shape with a certain angle and curvature. Bending is one of the most common sheet metal fabrication operations. Also known as press bending, flanging, die bending, folding and trimming, this metho... Read More

The stamping process can be divided into two categories?

Stamping and forming The stamping process can be divided into two categories: separation process and forming process. Separation process: The separation process refers to the process of separating the blank along a certain contour line to obtain a stamping part of a certain shape, size and cross-... Read More

What is the difference between sheet metal processing and stamping processing?

First of all, conceptually, sheet metal processing refers to the processing of metal sheets, which is to use sheets to make common items in our daily life, such as chimneys, iron barrels, oil tanks, ventilation ducts, elbows, and rounded places. , funnel-shaped, etc., it is mainly made by cutting...
