Plastic Chairs Making Machines

Meticulous division of labour, consecutive processes, professional of manufacture and high standard equipment ensure the high quality of the machine.

Factory introduced high precision maching tools, with the equipment of cutting machine tools, heattreating facilities, check out test sets and painting facilities, the processing ability for middle and large size machine, reach a high level in plastic industry while the quality if the machine is ensured at the same time.

The large size machine can produce different design of chairs.

Vertification of many year's market application, optimal combination configuration, stable, reliable and durable system with the characteristics of high efficiency, energy saving, low voice and strong power.

The strengthening design of template is carried out through multiple times of optimization design of major components such as template, based on the analysis of finite element software, which both guarantee the lifetime of template and protected mould.

High rigid template adopts the structure with coexistence of installation screw hole and T-shaped groove.

The tie rod of each machine model has passed the test by professional testing organization, which means that, the deflection of tie rod is within reasonable scope while guaranteeing the operation of machine.
