Motion, the biomass in cartridge heater are pressed in the taper sheath in molding sleeve by jumper bar, and straw is in mechanical pressure and the effect of temperature
Lower generation plastic deformation, after straw is squeezed into moulding stick, extrudes after protecting the steady type of type tube.Under the effect of reversal valve, oil quilt
Pump into another chamber of oil cylinder, then piston, piston rod, jumper bar move to the other end, complete other end molding.But now to temperature
Control the most rule of thumb set the punching press interval of oil pump and control heating-up temperature, but be as machine work machine internal
Temperature raises and heat time heating time all can be impacted by the error of machine work, thus affects yield rate and the product product of processing
Matter.
