Description
The gravimetric extrusion control system utilizes the loss in weight principle to control and maintain a consistent weight or thickness of extruded product. Our gravity measuring system is used in the extrusion line to make online measurement and control the product weight and the hourly output of extruder.


Materials

Gravimetric extrusion control system is suitable for the materials of granule, (rubber), powdery, mixture and untreated raw material with the good performance of mobility.


Application

Picture1: The material starting-up status. This gravimetric extrusion control system is installed between the material storage hopper and the extruder throat. It monitors the loss in weight of the material in its weigh chamber and from this calculates the mass throughput rate of the extruder. In auto control mode our product can control the extruder or the production line speed to maintain a set output or a set product weight per unit length.

Picture 2: While the material reduces little by little, the system will do the real time measurement of per-meter weight and extrusion output continuously.

Picture 3: When the weight of material in the weigh chamber falls below a preset value, a slide valve will open and refill the chamber from the material storage hopper. Then a new measurement and control process begin

Advantages


1. High technical

This kind of product is mainly used in plastic extrusion industry, and its market share is 30%. Our product has been investigated and surveyed for a long time in different industries for different extrusion equipments to satisfy client’s requirements of vibration resistance, stability and high precision in measurement and control process. Our gravimetric extrusion control system is a kind of innovative integrated equipment with high technical content which is suitable for real time high precision weighing, rapid automatic calculation and online control the extrusion output and weight per length. Now it is suitable for all of the extrusion production lines and all control methods.

2. Easy installation and Easy operation

Different from Regular LED Display, we assemble the whole parts before delivery; minimize the work of our clients.
At the same time, you don’t have to be confused with the complicated operation as usual, easy operation is what we emphasize when design.


3.High cost effective

More over, the parts of our gravimetric extrusion control system all utilize the high-end brand in the world to ensure the products running stable. Because the procurement and manufacturing cost are much higher than other manufacturers, so our product has the high cost effective.


4.Simple operation

Our gravimetric extrusion control system is specifically designed according to user’s operation habit and working environment which makes the user can quickly master the operation of the equipment. (This kind of equipment just needs to set two numbers and presses two buttons to automatically control the whole production line. The alarm information needs to be manually eliminated to avoid the loss caused by workers who doesn’t notice the alarm information.)


5.High accuracy

The control precision is 3‰, and it is far higher than competitor’s 4‰.


6.Double function

Our gravimetric extrusion control system can simultaneously control the weight per length and extrusion output, which breaks the limitation of other machine that can only control weight per length or extrusion output, and contribute to efficient control of production line. Our control system is particularly suitable for the extruder with unstable extrusion output that caused by a variety of factors. Even there are application cases to prove that our equipment can control the production line that is on the edge of scrapped and produce qualified tubular product. Thus bring big benefit for the customer.  


7. Cost saving

Gravimetric extrusion control system can save 4-5 times material than competitor for it only needs a few minutes to start and function, don’t needs to be adjusted for many times to avoid the waste of material and unqualified products. Also our control system makes the operation became simple thus the workers only need to set the product specifications (weight per length and extrusion output) in production process Customer don’t need to pay a lot of money to employ experienced worker. More over, this control system with alarm function can quickly adjust the production line to avoid unqualified product when the presetting numbers reach to the upper and lower limit degrees.


8.Price advantage

We only charge 70% price by contrast with Germany competitor and at the same time, we promise our clients enjoy high quality product and service.


9.High quality

With strict quality control and good performance, our product gets the CE certificate and occupies the leading position in this area no matter in appearance, technology and sales volume.


10. Service advantage

We are the professional gravimetric extrusion control system manufacturer in China who can provide one year warranty and life-long free software update services. Also we offer 24 hours service to ensure your normal production. With high quality and excellent after-sale service our product gets consistent high praise.


Installment

This equipment is installed on extruder’s feed opening which instead of storage hopper and accurately control the required material per hour, and the required material per length to ensure user can produce qualified products with short boot time and low labor cost.
