Precision Grey Cast Iron Shell Casting is one of Losier's core products with long-term focus and proven mass production experience. As a China Precision Grey Cast Iron Shell Casting Manufacturer & Supplier with nearly 40 years of casting and machining experience, Losier can provide customers with high size stability, high surface quality and high consistency precision gray cast iron shell casting solutions according to different structural complexity, stress conditions and application scenarios.
Relying on experienced engineering team and multi-process flexible production system, we can flexibly switch between shell casting, sand casting and automatic molding process, and help customers achieve better comprehensive cost control under the premise of ensuring stable performance and quality. Products are widely used in automobile manufacturing, rail transit, engineering machinery, automation equipment, aerospace equipment, communication equipment, hardware tools and other high-demand industrial fields.
Precision Grey Cast Iron Shell Casting is a high-precision casting process using resin-coated sand shells as cavity carriers. The process can greatly improve the size precision and surface quality of castings while ensuring good shock absorption property, wear resistance and machining performance of gray cast iron, and is especially suitable for industrial parts with complex structure, high wall thickness uniformity requirement and strong batch stability.
Compared with traditional sand casting, shell casting has the following significant advantages:
Greater size consistency
Lower surface roughness
Reduce machining allowance
Suitable for medium and large batch stable production
Losier applies Precision Grey Cast Iron Shell Casting to a wide range of industrial systems where reliability, longevity and assembly accuracy are critical.
High damping performance: gray iron graphite structure effectively absorbs vibration, suitable for dynamic load conditions
Excellent wear resistance: suitable for long-term friction and repeated operation parts
Good machinability: reduce tool wear and improve machining efficiency
Strong size stability: suitable for high assembly precision systems High consistency in shell casting: stable and reliable batch delivery
