Casting & Forging

A high-temperature metal forming process (above recrystallization temp) for ductile metals. Applies extreme pressure to shape billets, enhancing strength/density via grain refinement. Produces durable, load-bearing components (gears, shafts) with excellent mechanical properties, ideal for high-stress industrial applications.

Sand Casting

A versatile casting method using sand molds for complex metal parts. Molten metal pours into sand cavities; molds break post-solidification. Cost-effective for low-to-medium batches, accommodates large sizes/intricate designs. Suits ferrous/non-ferrous metals, widely used in machinery and automotive components.

Investment Casting

A precision process: wax patterns form ceramic shells, wax melts out, molten metal fills. Delivers tight tolerances, smooth surfaces, and intricate details (thin walls, complex geometries). Ideal for high-precision parts (aerospace, medical) in stainless steel, superalloys, and non-ferrous metals.

Die Casting

High-pressure injection of molten non-ferrous metals (aluminum, zinc) into steel dies. Enables mass production of complex, dimensionally accurate parts with fine surface finishes. Offers high efficiency, material savings, and excellent repeatability—key for automotive, electronics, and consumer goods components.
