This model operates using a chain-driven mechanism with automated program control, ensuring consistent packaging speed and uniformity in packaging and sealing quality. Compared to similar domestic models, this model completely eliminates the mechanical program control method and instead employs dedicated PC and step programming, an inductive control system, featuring the characteristic of automatic tracking continuity. The mechanical working precision is significantly enhanced, resolving the key issue of poor reliability in the interlocked vacuum packaging machines that has not been solved by similar models for many years, making it a domestic innovation. The machine is compatible with a German vacuum pump with a capacity of 100 cubic meters per hour.
