FLEX500 tinting machine

FLEX500 tinting machine

The Corob FLEX 500 is an ideal family of turntable dispensers built with a simple yet effective design for handling the evolving nature of the colorants. The dual direction turntable is optimized for use in smaller areas with a silent DC motor and techno-polymer gear train. This setup both provides a faster dispensing reaction time and makes the unit suitable for all the working environments.

The high compatibility techno-polymer brush allows the unit to work with water and organic solvent based colorants. The brush rotates with a 90° axis compared to the dual directional turntable’s plane surface. This guarantees a complete cleaning cycle in both directions, greatly improving cleaning time.

A stainless steel pump, POM valve housing and the everlasting three-way, two-position ceramic valve work in synergy to ensure efficient and precise colorant dispensing. The valve manages the operations during the suction, re-circulation and dispensing circuit phases. Its design also prevents colorant leaking by creating an air tight seal. The higher liquid tolerances and better control of color dispense deliver the best results in color accuracy

Gravimetric function

Corob’s FLEX 500 and FLEX 540 product family also feature a gravimetric dispensing function. The embedded software controlling the unit can manage the connection to an external scale. With gravimetric dispensing, the amount of each dispensed colorant is checked by an accurate weighing platform; the scale therefore gives a continuous feedback to the machine’s software. The machine dispenses colorant until the threshold level has been reached in order to obtain a certain formulation.

Gravimetric systems are typically used by customers requiring a high and constant accuracy. Application nowadays are the ink-industry and in-plant tinting.
