A-1:Casting method:

At present, the precision casting process we adopt include: vacuum casting, lost wax investment casting and low pressure casting, the vacuum casting products’ advantage is the most outstanding in our company.

(1) Vacuum casting can help the excluding of gas in the mould and inhibit the turbulence and the volume of gas. It can overcome the disadvantages of the traditional casting, and make the filling ability of the metal liquid improve significantly.

(2) Because of the improvement of filling ability while vacuum casting, the metal liquid’s casting temperature can be lower than the traditional casting about 20~30 degree.
