138T Cold Chamber Die Casting Machine for Door Lock Hardware Aluminum Lock Panel Frame Diecast Machine

As a highly versatile production solution for door lock manufacturers with diverse product portfolios, this 138-ton cold chamber die casting machine covers the complete range of lock hardware production: decorative and functional lock panels, lock body frames, door handles and levers, plus a wide variety of small internal fittings and mounting components. It is the ideal all-in-one machine for lock factories that need flexible production capacity across multiple product lines.

Equipped with a German PLC system and intuitive color screen, the machine provides precise, repeatable monitoring and control over injection speed and pressure for every product category. Servo motor drive with closed-loop feedback control enables flexible, on-the-fly adjustment of injection parameters, allowing quick and seamless changeover between panel, handle, frame and fitting production without sacrificing casting quality or process stability.

The dual-proportional hydraulic system achieves fully programmable multi-stage injection and low-pressure mold clamping, and is fitted with high-quality European or Japanese oil seals for long-lasting, leak-free reliability. The clamping and mold height adjustment system ensures even stress distribution and accurate mold positioning regardless of mold size, while the injection unit with high-flow valves and precision piston accumulator adapts seamlessly to different mold designs, gating layouts and part geometries across all lock hardware categories.

Built on a heavy-duty, stress-annealed machine frame and cooled by a high-efficiency oil cooling system, the machine delivers consistent performance and a service life of 15–20 years under normal industrial production conditions. An optional mold sweeping robotic arm is available for customers looking to upgrade to automated production cells.
