NBSJ SS304 Silica Sol Precision Investment Casting

Stainless steel silica sol cast lost wax cast precision investment casting products

The investment casting structure of Ningbo Suijin includes an investment main body, an investment core, a molding core, and an inner gate; the investment main body includes a support shaft, a first sleeve connected to one end of the support shaft, and a first sleeve connected to the other end of the support shaft. Two shaft sleeves; the investment core is built into the investment main body, the forming core is connected to the second shaft sleeve, and the inner gate is connected to the first shaft sleeve. The investment casting structure of this utility model is solved by embedding the investment core in the investment main body The problem of deformation of the investment mold due to its thickness is solved; the quality of the blind hole is ensured by the clamping of the second sleeve by the forming core; the diameter of the investment core is increased by setting the first sleeve on the investment core to ensure the product No manufacturing defects. The investment casting structure significantly improves production efficiency, improves product quality, and greatly reduces production costs.
