High-quality steel castings made with advanced processes tailored to your design and performance requirements
Lost wax casting enables the production of high-precision, complex steel components with excellent surface finish and dimensional accuracy. Ideal for intricate designs, it reduces machining and assembly requirements while maintaining material integrity.
Lost foam casting allows near-net-shape production of steel components with complex geometries and minimal draft requirements. It is suitable for medium-to-large parts requiring high strength and reliable dimensional control.
Shell mold casting provides precise, smooth-surfaced steel components, suitable for medium-sized parts with high dimensional requirements. The method ensures consistent quality and repeatability in production.
Sand casting is a versatile and cost-effective method for producing large or structural steel components. It allows for flexible design, high strength, and efficient production, making it ideal for heavy-duty and construction applications.
High-quality steel materials tailored for diverse casting requirements
Carbon steel is cost-effective and strong, making it ideal for general mechanical and structural components. It offers reliable performance while supporting efficient production of complex shapes.
Alloy steel offers high strength and wear resistance through carefully controlled composition and heat treatment. It is ideal for load-bearing and complex components requiring durability and precision.
Stainless steel provides excellent corrosion resistance, making it suitable for high-precision, durable components exposed to harsh environments. It reduces post-processing while maintaining dimensional stability.
High manganese steel is exceptionally wear-resistant and impact-resistant, making it ideal for heavy-duty and abrasive applications. It maintains toughness under high stress and extends component service life.
