What are the characteristics of precision casting?

1. Not limited by casting size, thickness, thickness and shape. Flexible production method.

2. Widely used materials, large amounts of scrap metal and renewable resources can be utilized, and energy consumption is less than forgings.

3. Castings have certain dimensional accuracy and small machining allowance, which can save metal and processing time.

4. Low cost, high comprehensive economic benefits, low energy consumption, consumables and costs. Precision casting is a common casting method, also known as lost-wax casting, which means selecting appropriate investment materials (such as paraffin) to make investment patterns. The investment mold is repeatedly painted and sprinkled with refractory sand to dry the hard shell and shell, and then the investment mold in the shell is melted to obtain a cavity so that the roasted shell has sufficient strength, the remaining investment material is burned out, and the required metal is poured Material, cooling and solidifying the shell to obtain high-precision finished products. Cold and heat treatment and surface treatment are carried out according to product requirements.
