Pump shell castings produced by investment castings process with
alloy steel material
Precision casting is also called lost wax casting, its products are
precise, complex, close to the final shape of the parts, no
processing or very little processing on direct use, is a near net
form of the advanced technology. We use this process produce lot of
pump shell products with carbon steel material or stainless steel
materials, and these products are been widely used in different
industries.
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.
| Casting material | Carbon steel, alloy steel, stainless steel, other material |
| Casting weight | 0.01kg~100kg |
| For pump shells | 1kg~10kg |
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.
