138T Cold Chamber Diecast Machine for Window Handle Aluminum Door Handle Machine

Designed specifically for door lock hardware factories operating long-term, multi-shift continuous production lines, this 138-ton heavy-duty cold chamber die casting machine delivers exceptional mechanical stability, extremely low failure rates and an extended service life. It is built to keep producing lock panels, frames, handles and fittings reliably shift after shift, minimizing unplanned downtime and helping lock manufacturers secure on-time delivery for large bulk orders.

At the control core is a genuine German PLC with a high-resolution color touch screen, enabling accurate, real-time monitoring and control of injection speed, pressure and all process variables around the clock. The heavy-duty, stress-relieved machine frame and proven, robust hydraulic system together ensure long-term continuous production with minimal downtime, giving lock manufacturers the production reliability they need to honor tight delivery schedules for all types of lock hardware.

The dual-proportional hydraulic system realizes smooth multi-stage injection and controlled low-pressure mold clamping, and is fitted with high-quality European or Japanese oil seals that are engineered to withstand prolonged operation with excellent wear resistance. The clamping and mold height adjustment mechanism guarantees uniform stress distribution across the mold and highly stable mold positioning over millions of cycles, while the injection unit with high-flow valves and precision piston accumulator maintains steady, consistent injection performance day after day.

Powered by a high-efficiency servo motor with closed-loop control, the machine offers precise injection speed regulation and lower energy use. Its efficient oil cooling system maintains stable hydraulic operating temperature even during peak summer production, supporting a total service life of 15 to 20 years. An optional mold sweeping robotic arm is available for customers running fully automated production lines.

We guarantee delivery within 20 days of order confirmation, backed by 2-hour rapid response + 24-hour on-site after-sales service, dedicated one-on-one technical support, on-site commissioning by certified engineers, ongoing technical guidance, and we welcome all customers to visit our manufacturing facility for inspection and audit.
