Drainage sand has good natural fluidity and low thermal expansion tendency

Drain sand can reduce the formation of lost foam casting. Do you know? So why should it be reduced? How did it decrease? Don't worry, the manufacturers of drainage sand will find the answer when they look down:

1. Drainage sand manufacturers do not need to lower the core, the consumption is very small, can not be calculated, compared with cast steel, each ton of casting can save more than 1.2 tons of molding sand. Compared with cast iron, it can save the cost of additional materials, shell roasting cost, core making cost, core iron cost.

2. The appearance efficiency has improved significantly, and no longer needs appearance workers, which can save more than 40%-60% of labor.

3. The liquidation man-hour can save 90% of the drainage sand, and the steel casting can save the gas cost of cutting the flash burr.

4. The yield of molten iron is improved by 10-30%, especially the ductile iron parts can be completed without riser pouring.

5. Stainless steel, high manganese steel and ductile iron can be treated with waste heat solution, which greatly saves energy consumption.

6. Single-piece products do not need to be made of wooden molds.

7. The improvement of casting accuracy of drainage sand manufacturers can complete no or micro machining, which not only reduces the weight of castings, but also saves the cost of machining hours.
