Laminated sand cast water pump valve

The choice of forging pouring location depends on the type of alloy, the casting structure and contour specifications, the casting surface quality standard and its current status. While simplifying the molding and pouring process as much as possible, the key is to determine the casting quality when choosing the casting pouring location.

How to improve mold quality, service life and control production costs has become a pressing issue at present. Improve the quality and service life of the mold and reduce the cost of investment casting price is the application of surface solution technology in the mold manufacturing. Only change the composition, organization and performance of the mold surface, by using different surface solution technology, greatly improve and enhance the surface performance of the mold, such as strength, wear resistance, abrasion, mold exit, thermal insulation, corrosion and high temperature anti-oxidation reflectivity, improve the special performance of the mold, such as cavity surface scratching, mold exit, anti-seize, improve the service life of the mold is many times, dozens of times. This plays an important role in improving the quality of molds for investment casting process, greatly reducing product costs, increasing production speed, and giving full play to the potential of mold materials.
