Advantages of automatic extrusion blow molding machine:
1. Its control system adopts closed loop control imported from Europe and hydraulic system is pressure-flow double proportional control equipped with variable plunger pump to ensure fast and smooth operation of the machine and energy consumption of the hydraulic system can be reduced by 30% or above, saving considerable electricity.
2. This series adopts new patent of two pull-rod type closing-mold device; Double-folding accumulator head; Extrusion device, equipped with complete blowing device and product taking-outdevice, and entirely achieves full automatic production.
3. The electrical control system adopts Complete computer control to automatically conduct technical parameter optimization and trouble diagnosis with high control precision and good reliability.
4. This series, completely designed and manufactured according to German standards of same model is the model with ration of performance to price at present.
