FAQ

In theory, which is more expensive, forging parts or casting parts?

Compared with the price, the product with the same simple structure eliminates the material factorsThe forgings must be more expensive

What is the reason for 304 stainless steel precision casting parts to be changed?

Steel deformation control is one of the most common problems in the metal processing industry. Any process will occur. The casting is the largest deformation and the least fine. It is generally used to produce blank blanks

The difference between cement sand castings, resin sand castings and vacuum casting parts

Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
