We input carefully selected raw materials (ingots, scraps) and melt them in a high-frequency induction furnace.
Additional mixing alloys such as components and alloy ratios can be tailored to customer requirements.
A method where molten metal is poured into a sand mold. Suitable for simple shapes or small/medium/large product production, and facilitates small quantity batch production.
Produces materials with very dense structure and excellent mechanical properties using the centrifugal force of high-speed rotation.
High dimensional precision and beautiful surface finish minimize machining processes. Effective for complex designs or small/medium quantity specialized parts.
