Gravimetric System Dosing Feeder for Plastic Extrusion Machinery HDPE Pellet

Gravinetric Dosing Feeder works as adjusting extruder screw speed and haul off speed to realize controlling

the pipe wall thickness,setting it in a stable value. Walthmac supplies Gravimetric Dosing System for plastic

pipe industry, this system is used for control the extruder's screw speed and haul off speed to maintain the

thickness of pipe in a setting value.So machines will help to save materials for manufacturers.

Parameters controlled to be constant by this system,machine is applicable for many industries:

- Plastic Pipe

- Cables 

- Optical Cables

- Plastic Film

(By controlling the speed of screw and haul off,realize adjusting pipe wall thickness in real time. )

                                                           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

1. Shorten start-up time, lower the rate of disqualification

2. Gravimetric Dosing feeder could save raw material 1% to 5%

3. Easy use and maintenance, even new workers can directly working with.

4. Automatically collecting data of extruder capacity, meter weight, wall thickness and feedback to control system instantly

   for real time adjustment, etc.

5. Close-loop control design from both sides of extrusion and haul-off to reach high Precision rating of 99.5 ~ 99.7%.
