Extrusion Control Raw Material Feeder Gravimetric Doser For Plastic Pellet Extrusion

- 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. )

                                            Gravimetric Doser Models Selection

 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.

l Initial commissioning of systems

l Functioning test

l Final inspection with the customer

l Extension: Further training
