Designed to produce heavy‑duty aluminum alloy EV traction motor casing for electric vehicles, commercial trucks and light‑duty delivery vans, our 650T cold‑chamber die‑casting machine focuses on high‑density casting forming for high‑load powertrain parts. Traction motor casing bears continuous vibration, temperature fluctuation and mechanical stress while vehicles run on various road conditions. High structural density and impact‑resistant performance are essential to protect internal motor parts from external damage.

With 650‑ton powerful clamping force and ultra‑rigid welded frame, this cold‑chamber die‑casting machine can handle large, thick‑wall aluminum traction motor casing moulds. Reinforced platens and high‑strength tie bars resist deformation under huge injection pressure. Molten aluminum fills the whole mold cavity steadily, and sufficient holding pressure compacts casting structure, reducing hidden porosity inside high‑stress zones of traction motor casing. This greatly improves mechanical strength and fatigue resistance of finished aluminum motor casings.

Advanced PLC closed‑loop injection control enables operators to set multi‑phase injection parameters according to wall‑thickness distribution of traction motor casing. Slow filling for thick‑wall sections and fast filling for thin‑wall outer shells can be achieved on one machine. Optimized injection curves help eliminate cold shut marks, oxide inclusions and surface defects, lowering rejection rate in subsequent machining and leak‑testing procedures. Built‑in fault diagnostic function reduces unexpected shutdown time during mass production.

Upgraded heavy‑load hydraulic system is built for long‑hour continuous casting of large aluminum EV components. High‑end hydraulic seals prevent oil leakage under heavy pressure. Hydraulic mold height adjustment system accelerates mold change‑over for different traction motor casing specifications. Intelligent pressure‑relief energy‑saving system cuts down idle power consumption and helps casting factories achieve lower production cost per workpiece.

Stable clamping force guarantees consistent mold closing status throughout every casting cycle. High‑capacity accumulator injection unit delivers powerful, controllable metal filling force. High‑efficiency oil cooling system keeps hydraulic system working at constant temperature. Automatic part‑removal robotic arm can be installed as optional upgrade for unmanned batch production workflow.
