Extrusion Control Plastic Material Feed System Gravimetric
Doser
1. System Introduction
- Material saving 1- 5%.
- Precisely control the minimum wall thickness within the allowable
range.
- Make the production process smoother and more stable.
- Start production after set values,no need to commission.
- 7/10 inch large screen HD display & easy to operate.
Principle:
The Gravimetric doser is used for pipe wall thickness control
for plastic pellet extrusion process. According to the preset meter
weight/extrusion output value, the system will adjust the screw speed and haul off speed in real
time based on its adaptive algorithm to achieve the real-time control of the pipe thickness.And the system will keep the wall
thickness constant at the minimum value,that will greatly reduce costs.
Applications:
- Plastic Pipe/ Cables / Optical Cables/ Plastic Film
(By controlling the speed of screw and haul off,realize adjusting
pipe wall thickness in real time. )

3. What Gravimetric Dosing Feeder could do for you?
1. Shorten start-up time, obtain production data when you
start with this system.
2. Help to save 1%-5% raw materials by production at minimal qualified wall thickness range.
3. Stable production process, improve pipe
quality.
Parameters controlled to be constant by Gravimetric Extrusion
Control System:
● Extruder throughput
● Meter Weight
● Gravimetric Feeding System can simultaneously control the
extrusion throughput and meter weight to promise constantly manufacturing qualified products. It is wildly used on
the extruder to avoid unstable extrusion throughput caused by various factors.
3. Product Description of Gravimetric Doser
Walthmac gravimetric control system is easy to use,the only one
thing you should do is set the meter weight/ extrusion output value.Then the system will start to work.If the meter weight
figure deviate from set value, the system will prompt an alarm in time to avoid quality risks.
