02 / What We Solved

Requirement And Solution

What the customer needed to produce, and the line we configured to get there.

12 Component Gravimetric Dosing System
Requirement

What The Customer Needed

The customer needed an Automatic Powder Weighing Batching System for multiple materials with high dosing accuracy, easy operation, and convenient cleaning.

The main requirements included:

12 material hoppers for different powders or additives
High weighing accuracy for small-dose ingredients
Automatic screw feeding and weighing
PLC control with touch screen operation
Stainless steel material contact parts
Easy formula storage and quick recipe changeover

Solution

What We Supplied

QTech-Machinery provided a customized Plastic Color Powder Dosing System with 12 independent feeding units. Each hopper is equipped with a servo-controlled screw feeder to ensure stable and accurate material dosing.

The system works as a Servo Screw Gravimetric Dosing Machine, combining precision weighing, servo screw feeding, PLC control, and automatic recipe management. It helps the customer improve batching accuracy, reduce manual weighing errors, and increase production efficiency.
