Cold Chamber Die Casting Machine Chair Support Base Machine Chair Foot Base

Optimized for large-scale batch production of standard aluminum heavy-duty chair spider bases for furniture assembly factories and wholesale distributors, this 650-ton cold chamber die casting machine supports multi-cavity mold simultaneous forming. High demand from office furniture manufacturing and commercial seating projects requires high output volume, stable batch consistency and low unit cost for chair bases. This 650T equipment solves the points of low single-cavity output and unstable quality in traditional production, making it the core production solution for large furniture hardware manufacturers supporting bulk OEM delivery of heavy-duty spider bases.

Equipped with an extra-heavy-duty fatigue-resistant frame structure, upgraded high-strength wear-resistant tie bars, enlarged thickened steel pins and extra-thick load-bearing platens, the machine boasts greatly improved overall structural rigidity and ultimate pressure-bearing capacity to support multi-cavity high-pressure production. This heavy-duty construction delivers stronger impact resistance and load stability during long-cycle high-pressure die casting, effectively reducing mechanical fatigue deformation and equipment wear during uninterrupted batch runs. For mass-produced chair spider bases, it ensures consistent filling density and dimensional accuracy across every cavity, cutting sorting, deburring and rework costs significantly.

Adopting an advanced German PLC intelligent control core and color HMI interactive touchscreen, the machine simplifies complex electrical circuits and realizes intelligent recipe management. The independent closed-loop control system supports real-time precise adjustment and one-click storage of injection speed and pressure parameters, enabling rapid parameter switching for different spider base specifications. It ensures stable forming quality and zero batch deviation for mass-produced aluminum heavy-duty chair bases. The equipment runs stably even in high-temperature workshop environments, and the built-in fault display function quickly feeds back electrical and hydraulic abnormalities to keep mass production running without interruption.

The dual-proportional hydraulic system enables programmable multi-stage injection and low-pressure anti-collision mold clamping, boosting filling efficiency and cycle speed while effectively protecting multi-cavity precision chair base molds. The entire machine is fitted with high-quality European and Japanese oil seals to ensure long-term stable, leak-free hydraulic operation and reduce daily maintenance frequency. The hydraulic die height adjustment system enables fast mold change and parameter debugging, greatly shortening switching cycles between different spider base models and improving overall mass production efficiency. The automatic pressure relief energy-saving system intelligently reduces idle energy consumption for energy-efficient batch manufacturing.

The precision clamping and die height adjustment device ensures uniform mold stress and stable positioning across the large 650-ton platen, avoiding batch quality deviation caused by mold displacement and pressure fluctuation. The injection system composed of high-flow valves and a precision piston accumulator delivers stable, powerful injection force that adapts perfectly to multi-cavity molds for various standard heavy-duty chair spider bases. Matched with an efficient oil cooling system, the equipment maintains constant hydraulic temperature and stable performance during long-term mass production, with a service life of 15 to 20 years. An optional mold sweeping robotic arm can be configured to further improve production automation and output capacity.
