20L-120L single station automatic blow molding machine

The 20L-120L drums, tool boxes and auto parts series consists of PTB75, PTB80N, PTB90N and PTB100 etc., which can be used for producing drums, tool boxes and hollow parts of all kinds. Materials of PE, PP, and ABS can be used. Maximum capacity of accumulator head can be 12L while volume of products can be 120L. 
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.
