Review capabilities →Aluminum ExtrusionsCustom Industrial Aluminum Profiles
Custom 6061, 6063 and 6005A aluminum extrusion profiles with tooling, cutting, CNC machining, anodizing and powder coating for industrial OEM assemblies.
Review capabilities →Metal + Magnets from One Supplier
Naturally Complementary
Most magnet assemblies need precision metal components — rotors need shafts, couplings need hubs, Halbach arrays need back-irons. We make both.
Consolidated Shipping
Magnets and metal parts ship together from Ningbo. One PO, one shipment, one quality framework — lower landed cost and faster receiving.
DFM Across Processes
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.
