Working principle of this GM-DP-R series continuous screen changer

As the polymer melt enters the main body ofthe screen changer, the melt stream is divided equally and flows into the two channels ,go through the two breaker plates, and the impurities are intercepted by the screen mesh, and when screen changing is required, one of the pistons with blocked screen pack is pushed out by hydraulic unit , and the other is still on the working position, we replace the fresh screen and then the piston with new screen is pushed into the working position, at this time, the air bleeding system also begin to work.  The other piston screen change is the same with above.  This type of continuous screen changer maintains a continuous melt flow.

Applications 
 
Cast film (Bubble pack/ Medical/Food Wrap)
Sheet (Foam/Strapping/Plastic cardboard)
Coating (Hot melt adhesive)
Pipe ( Corrugated/Gas Pipe) and profile
Compounding (Master batch/filler)
Wire and cable extrusion
Tubing (Medical/Industrial/Irrigation)
Fibers ( Monofilament/non-woven fabrics)
Pelletizing (strands and water-ring pelletizing)
Recycling of most polymers

Quality inspection
   We take only first-class steel and check every production procedure to ensure every dimension is produced precisely. A final complete inspection will be executed  before delivery.   we guarrantee that every set of scren changer   from our factory is the best quality.

Commissioning
We provide the operation manual for customers to gudie to install the screen changer, and at the requirement of user, salers should send technician to install and commissioning the die at site of Buyers, expenses of the trip should be borne by Buyers.
 
After-sales service
12 months with proper operation by user, all the spare parts shall be replaced free of charge under guarantee period, fee for transportation and packing will be borne by users.

Tips for customers

 

How to choose a most suitable type of screen changer for your extrusion line ?

After the equipment supplier making a size recommendation and then you should perform your own analysis to confirm appropriate sizing. That way, you will have the advantage of independent analyses and, best of all, there is no additional cost.
Learn the difference between price and cost. Be sure to take into consideration all of the variables and look at all the factors to determine the real cost of ownership for the screen changer. Some of the hidden variables to consider may be:
Product quality.
Maintenance, time and cost of parts.
Process downtime and cost.
Life expectancy for the equipment and amortized cost of ownership.
Cost and availability of filtration media.
Pressure loss and effect on line output and product quality.
Operator safety.
Required operator intervention and labor cost.
If all of these and other factors are taken into consideration, you can choose the most suitable solution, and then you can expect a much better return on investment.
