Pu30d-z low pressure tri-component PU sole forming machine is improved, finalized and manufactured on the basis of PU20D-Z model by our factory (patent no. : ZL95221220X). It consists of two polyol components and one isocyanate component, the two polyol components can be switched instantly to eject sole products of different colors or eject same sole product of different density. If has been highly commented by users for its advantages of high production efficiency, high qualified rate, simple operation and convenient maintenance.

double color double density PU foam dole products can be produced. when the preparations are same, it can be seen as two sets of bi-component(pu20d-z) foam sole forming machines.

PU30D-Z can be equipped with the following peripheral equipment:
Mixer head lifting gear
Industrial refrigerator
Concentrate auto feeding unit
Concentrate tank can be custom-made 80L-350L
Circular production line, number of work station 50-108, also can be custom-made

·usage
