Product Description



Continuous screen changer for non-woven fabric extrusion machine

Why do we need to use the screen changer/ melt filter on the non-woven fabric extrusion machine?
In nonwovens manufacture it is necessary to achieve a uniform spinning quality across all spin packs. Therefore, any in homogeneities must be removed before they enter the spinning beam. Moreover, process consistency regarding pressure and temperature is the basic prerequisite for an efficient production. Our GM-DP-R series double-piston continuous screen changer is widely used on spun bond and melt-blown nonwovens production lines

Benifits of this GM-DP-R seriespolymer melt filter 
1, Eliminates line shutdown thus increasing production 
2, Leakage-free process 
3, Two breaker plates design increases filtration area compared to single breaker plate design 
4, Reduced downtime & scrap 
5, Reduced inlet pressure at extrusion die 
6, Reduced temperature variations in the melt ·

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.
