In-house tooling, five casting processes, precision CNC, six surface-finishing routes and full assembly — Hiyet shortens your supply chain without sacrificing quality.
From sub-100-gram telecom parts to 25-kg structural castings, we pick the right process for cost, lead-time and metallurgy.

280-ton to 4,000-ton machines. Best for thin-wall (1.5–6 mm) structural and housing parts at 5k–500k pcs/yr volumes. Cycle time 30–120 s.

Dense, porosity-free structures — ideal for wheels, brackets and EV battery trays that need T6 strength.

Best mechanical properties in T6 condition — UTS ≥ 280 MPa. Used for motorcycle, ATV and aerospace structural castings.

For low-volume, large-envelope or development parts — including aerospace components and prototype runs.

Net-shape parts with as-cast surface Ra 3.2 µm — medical, jewellery, complex geometries impossible to die-cast.

AZ91D / AM60 for ultra-lightweight 3C electronics, drones and consumer hardware — 30% lighter than aluminum.
