We use high-hardness gray iron to make molds, and use high-precision machining centers to process molds, which can ensure that the accuracy error of the product is 0.5MM, and the mold can be used more than 100,000 times. Suitable for making products with high precision and small weight.

The molding machine is used to spray 200 mesh sand into the mold to make the sand shell for casting, which needs to be kept warm for 7-12 hours after casting.

Molds are usually made of metal or wood to ensure their strength and stability. A special resin coating is applied to the inside of the mold, and the resin sand is poured into the mold using a sand making machine and compacted to form a solid sand mold. The liquid metal or alloy is poured into the sand mold and kept warm for 7-48 hours, and the molded casting can be removed.

The mold price is relatively cheap, suitable for the production of large castings and precision requirements are not strict products.
