Title: 138T Cold Chamber Die Casting Machine for Stable Mass Production of Door Lock Frame Components

Optimized for high-volume production of lock body frames, lock housings, mortise lock cases and internal frame structure parts, this 138T cold chamber die casting machine delivers exceptional process stability and repeatability for door lock hardware manufacturers running continuous production schedules. It is designed to produce frame parts with consistent wall thickness, accurate internal mounting features and low defect rates, directly reducing post-machining and assembly costs.

Control is managed by a German PLC system with an intuitive color touch screen HMI that provides complete digital oversight of injection speed, pressure and all critical process variables. Every production parameter is logged and traceable, making quality control transparent and simplifying process validation for lock frame parts supplied to OEM customers. The dual-proportional hydraulic system enables smooth multi-stage injection filling and low-pressure mold clamping, allowing operators to fine-tune the fill profile for complex lock frame geometries with deep ribs, screw bosses and snap features. Premium European or Japanese oil seals are used throughout the hydraulic circuit, ensuring long-term leak-free operation and low failure rates even under heavy daily use.

The clamping unit with precision mold height adjustment ensures uniform stress distribution across the mold parting line and highly accurate mold alignment shot after shot. This is particularly important for lock frame components, where consistent dimensional accuracy of internal slots, pin holes and mating surfaces directly affects assembly fit and function. The injection system incorporates high-flow directional valves and a precision piston accumulator that delivers consistent shot volume and injection velocity, making the machine highly compatible with various lock frame mold layouts, including single-cavity and multi-cavity tooling.

Driven by a high-efficiency servo motor with closed-loop feedback, the machine achieves precise injection speed regulation while reducing overall energy consumption compared to conventional hydraulic machines. Its robust, stress-annealed machine frame and efficient oil cooling system maintain stable operating temperatures during extended production runs, supporting a service life of 15 to 20 years. An optional mold sweeping robotic arm is available for customers looking to further automate their lock frame production cells.
