precision injection molding machine

MITA-TC SERIALS ( TWO-COLOR )

TWO-COLOR INJECTION MOLDING MACINE
Specially designed for producting keyboards and marble-effect products. The machine fits independent TWO-COLOR INJECTION SYSTEM, and can also function for single-color injection.
CLAMPING UNIT
	Clamping system uses horizontal and internal double-toggle mechanism, the which can shorten cycle-time.
	THE ROTATION SYSTEM OF TWO-COLOR MOLD, according to the different design construction of mold, two different models for the rotation system of movable-mold can be selected, ROTATING-PLATE DESIGN and ROTATING-AXIS DESIGN.
1.	ROTATING-PLATE DESIGN:
	To rotate the complete movable-mold, and can bear the heavier complete movable-mold.
2.	ROTATING-AXIS DESIGN:
	To rotate the core of the movable-mold, and has advantages of light, speedy and precise fixing-position.
TWO STANDARD MOLDING PROCESS:
1.	Mold open end -->Middle ejector forward --> Mold rotation --> Middle ejector return -->Clamping close -->Robot
2.	Mold open end --> Ejector A B --> Middle ejector forward --> Robot --> Stop --> Middle ejector forward --> Mold rotation --> Middle ejector return --> Clamping close.
INJECTION UNIT
	A B nozzles are arranged in parallel horizontally, with the mold-rotation device on the movable platen, to reach the high precision of two-color injection.
	Two-color molds at on time, time-saving ensures the improvement of the business profitability.
COMPUTER CONTROL UNIT
	Several ejector-method designs control.
	Easily correcting-program matches the molding process of different molds.
	Mold open/close stroke, A B barrel stroke are controlled by transducers.
HYDRAULIC UNIT
	Two pumps, two proportional valves, and full-proportional hydraulic-loop control.
	Two-stage control of mold-rotation speed.
	The standard hydraulic-loop includes ejector A B, middle-ejector, and mold-rotation.
