Quality Control
 

Liquid Color Masterbatch Controller is assembled and inspected before shipment according to confirmed configuration, control and liquid dosing factory inspection requirements, and factory inspection requirements. Key inspection items include pump speed control, injection volume stability, signal linkage, alarm function, and wiring status. Video inspection or third-party inspection can be supported before shipment.

 

Frequently Asked Questions
 
 

1. Is liquid viscosity information needed?

 

-

Yes. Liquid viscosity affects pump selection, flow range, and dosing stability.

2. Can it control a peristaltic pump?

 

-

Yes. Gear pump or micro-pump control solutions can also be selected according to the system.

3. How does it connect with an injection molding machine?

-

It can receive injection molding machine running, injection, or cycle signals and dose by set time or volume.

4. Can dripping be reduced?

 

-

It can work with anti-drip nozzles, short tubing, and suck-back control design.

5. How is color changeover handled?

 

-

Emptying, flushing, or color-change programs can be set. Actual performance depends on tubing length and liquid color.
