With its extensive experience in aluminum alloy casting, iron casting, steel casting, precision machining, and mold manufacturing, Losier has become a trusted Chinese shell mold casting manufacturer and supplier for numerous overseas clients. Losier focuses on providing a one-stop supply chain service from shell casting → precision machining (CNC) → heat treatment → surface treatment → assembly, helping clients save at least 30% on overall costs and significantly shorten development cycles.
Shell Mold Casting is a metal casting process that uses resin sand to create a shell. It is widely adopted by industrial users worldwide due to its:
superior dimensional accuracy compared to conventional sand casting
smoother casting surfaces
higher consistency and stability
suitability for medium to large batch production
and its suitability for such production.
| Advantageous projects | Explanation |
| High dimensional accuracy (tolerance up to ±0.02mm) | Reduces post-processing and improves assembly accuracy. |
| Low surface roughness (Ra 1.6–12.5) | Superior to sand casting, even approaching some precision casting results. |
| Wide range of applicable metals | Suitable for aluminum alloys, iron, steel, stainless steel, copper, brass, etc. |
| Stable mechanical properties | High density, uniform structure, and low porosity. |
| Low mass production cost | Shell molds can be automated for high efficiency. |
| High consistency | High reliability of products in the same batch, suitable for mechanical parts and safety components. |
