620T Servo Injection Molding Machine ZH-620

The ZUIHUI ZH-620 is the top-tier ultra-heavy-duty flagship industrial injection molding machine of the whole series, specially developed for unmanned, high-precision and high-intensity mass production of oversized integrated plastic parts, super-heavy thick-wall products and large high-load molds.Adopting an integral thickened cast steel frame and upgraded heavy-duty five-point double-toggle clamping structure with finite element optimization and stress relief treatment, the machine achieves industry-leading structural rigidity and excellent anti-fatigue performance. Uniform tie-bar force distribution ensures zero deformation and outstanding dimensional consistency during long-term high-pressure continuous operation.Equipped with an ultra-large clamping force of 6280kN and a supreme theoretical injection weight of 2895g, it delivers massive plasticizing displacement, uniform melt mixing and powerful injection thrust. It perfectly solves common difficult defects of large parts such as short shot, shrinkage, uneven stress and weak weld lines, fully adapting to super-thick-wall products, large integrated shells and high-fiber modified engineering plastics.Featured with the latest top-level full-servo closed-loop intelligent control system, it realizes millisecond-level accurate response and high parameter repeatability, achieving efficient cycle operation with lower energy consumption and noise. With ultra-wide tie-bar spacing, maximum mold capacity, long stroke and heavy-duty ejection system, it is highly compatible with various large non-standard heavy-load molds.It is widely applied for new energy vehicle large body panels, super-large logistics pallets, integrated home appliance shells, industrial equipment protective housings and giant plastic containers. ZH-620 stands as the ultimate benchmark model for unmanned, high-precision and energy-saving mass production of ultra-large industrial plastic articles.
