Hot Chamber Die Casting Machine Zinc Alloy Chair Leg Die Casting Machine Sofa

Purpose-built for manufacturing high-load-bearing zinc alloy sofa legs, table feet and chair support legs, this 138-ton hot chamber die casting machine delivers exceptional dimensional accuracy and uniform structural density, ensuring stable load performance and consistent assembly fit for mid-to-high end furniture hardware.

The machine adopts a newly reinforced frame structure, paired with high-strength tie bars, enlarged steel pins and thickened machine platens, which greatly improves overall rigidity and load-bearing capacity. This robust structural design delivers stronger impact resistance and better load stability during high-pressure die casting, effectively reducing mechanical vibration and deformation. For furniture leg production, this translates to consistently straight mounting surfaces, precise hole positioning and uniform wall thickness, ensuring reliable load-bearing capacity and smooth on-site assembly for every finished sofa foot, table leg and chair support.

At its control core is a genuine German PLC system paired with a full-color human-machine interface touch screen, enabling precise real-time monitoring and adjustable control over injection speed and injection pressure. Advanced closed-loop control technology enables ultra-fine regulation of injection speed throughout the entire filling cycle, eliminating internal porosity and structural defects that would compromise load strength. This dramatically improves first-pass yield and reduces the labor cost of machining and fitting adjustment before assembly. The control panel also features a built-in fault display function that quickly indicates electrical system abnormalities, helping operators resolve issues efficiently and minimize downtime even in high-temperature production environments.

The hydraulic system operates on dual-proportional control architecture to realize fully programmable multi-stage injection and low-pressure mold clamping, which protects precision mounting feature cores and load-bearing structural surfaces from impact damage. All hydraulic seals are sourced from premium European or Japanese brands to ensure long-term reliable, leak-free operation. The machine is fitted with a hydraulic die height adjustment system, making mold installation and changeover faster and more convenient to save time and labor. It is also equipped with an automatic pressure relief energy-saving function that effectively reduces system energy consumption during operation and minimizes unnecessary energy loss.

The clamping and die height adjustment mechanism ensures uniform stress distribution and stable mold positioning, while the injection unit with high-flow valves and a precision piston accumulator delivers accurate, consistent injection performance that adapts to various furniture leg mold designs. A high-efficiency oil cooling system maintains stable hydraulic temperature during extended production runs, supporting an overall service life of 15 to 20 years. An optional mold sweeping robotic arm is available for further automation upgrade.
