Precision Metal Components Manufactured to Drawing.

Die casting, investment casting, forging, CNC machining and extrusion for structural, thermal and functional OEM components.

High-pressure and gravity die casting in A380, ADC12, A360 alloys. Parts from grams to 20kg with CNC finishing.

Lost-wax casting in stainless steel, carbon steel, brass, and bronze. Complex geometry with minimal machining.

Closed-die and open-die forging in carbon, alloy, and stainless steels. Superior strength for critical parts.

3/4/5-axis milling and turning in aluminum, steel, stainless, brass, and engineering plastics.

Custom profiles in 6061, 6063, 6005A with anodizing, powder coating, and cut-to-length.

Metal + Magnets from One Supplier

🧲

Most magnet assemblies need precision metal components — rotors need shafts, couplings need hubs, Halbach arrays need back-irons. We make both.

📦

Magnets and metal parts ship together from Ningbo. One PO, one quality system, one shipment — lower landed cost and faster receiving.

📊

Our engineers optimize across the whole BOM: if a part can move from machining to net-shape casting and save 40%, we'll tell you.
