Alloy Steel Precision Investment Casting

Alloy Steel material Investment Castings Used for Construction Machine

We are supplying lot of structure castings with alloy material, produced by investment casting process. Such products are very common used on construction machines and other machines. There are also many similar products produced by welding process, but recently, lot of customers begin try to produce by casting process instead of welding process. Compare the cost and quality, we believe many of them can be better solution if we produce by investment casting process.

Following are the information about our investment casting production process.

The development of investment casting technology enables investment casting to produce not only small castings, but also large castings. The outline size of the largest investment casting is nearly 2m, while the minimum wall thickness is less than 2mm.At the same time, the investment casting is more precise, besides the linear tolerance, the parts can also achieve higher geometric tolerance.The surface roughness of investment casting is getting smaller and smaller, up to Ra3.2um.

It is always most important topic for our customers to reduce production cost but be sure the casting can meet with requirement. In this aspect, we have the most advantages. We have use different ways to get the mold:

• By sodium silica material;
• By composite material;
• By silica sol (low temperature wax)
• By silica sol (medium temperature wax)

We choose the appropriate process according to the different products of customers, to ensure that the products meet the needs of customers and reduce the production cost, to meet the needs of customers for different products.

We also help many of our customers develop new castings by this process, and also we try to use castings instead of other process for better cost control and quality control.
