400T Versatile Cold Chamber Die Casting Machine Aluminum Alloy Office Chair Pedestal Base Machine

This 400-ton multi-functional cold chamber die casting machine is designed for flexible customized production of diversified aluminum alloy office chair pedestal bases, including special-shaped 4-leg, 6-leg bases, designer creative chair bases, customized logo integrated bases and non-standard furniture hardware bases. Standard die casting equipment has poor adaptability to special-shaped and customized chair base structures, prone to incomplete filling and deformation. This 400T machine features flexible parameter adjustment and strong mold compatibility, meeting personalized customized production needs for various special and creative office chair bases.

Constructed with a versatile reinforced frame system, matched with high-strength tie bars, enlarged positioning steel pins and extra-thick machine platens, the machine has greatly improved overall rigidity, shock resistance and load-bearing performance for 400-ton clamping force. The stable mechanical structure ensures no vibration or displacement during high-pressure die casting, maintaining consistent forming quality whether producing standard five-star bases or special-shaped irregular chair bases. It has strong adaptability to medium-to-large aluminum alloy furniture products of different structures and details, and stably supports long-term flexible switch production of customized furniture parts.

Adopting a German PLC intelligent control system and high-definition color human-machine interface, the machine supports one-click storage and quick switching of multiple sets of production parameters. Operators can flexibly adjust injection speed and pressure according to the characteristics of different custom chair base molds, achieving targeted precision forming for customized products. Closed-loop speed regulation technology ensures stable and accurate injection parameters, avoiding quality fluctuation caused by frequent model switching. The simplified electrical system runs stably in high-temperature environments, and the real-time fault display function ensures rapid fault diagnosis and efficient production recovery.

The dual-proportional hydraulic system has strong compatibility, supporting multi-stage thin-wall precision injection for decorative special-shaped bases and high-pressure dense filling for structural heavy-duty bases, as well as low-pressure protective mold clamping for precision customized molds. Equipped with high-quality European and Japanese oil seals, the hydraulic system operates stably and leak-free for a long time under 400-ton working pressure. The flexible hydraulic die height adjustment system greatly shortens mold replacement and debugging time, improving the efficiency of multi-style chair base switch production. The automatic pressure relief energy-saving system intelligently reduces energy consumption during standby and operation, lowering production costs for customized multi-variety processing.

The uniform-stress clamping device and precise die height adjustment system ensure stable mold positioning and uniform force, adapting to various special-shaped and conventional office chair base molds. The injection unit composed of high-flow valves and a precision piston accumulator provides accurate and adjustable injection volume and pressure, meeting the forming requirements of diversified customized aluminum alloy chair bases. Equipped with an efficient oil cooling system, the equipment operates stably for a long time with a service life of 15 to 20 years. An optional mold sweeping robotic arm can be configured to improve production flexibility and automation level.
