difficulty

One-piece molding of large-size and complex inner-cavity structure products for fast delivery;

The traditional casting process has low qualification rate, high cost and long cycle time.

prescription

3DP sand casting process through the optimization of sand structure (7 pieces of sand core, 3 pieces of sand), to simplify the sand sand core assembly process, improve the positioning accuracy of high, reduce the weight of sand, save labor, reduce costs. It realizes one-piece molding of sand core for complex structure, and the product has good consistency of inner cavity molding, high dimensional accuracy, and better surface quality than traditional casting process.
