Process Chart

Feeding Machine Melting System Spinner
Reliable and robust feeding system integrated with powerful windlass. Exhibiting great efficiency of transferring materials directly to the melting furnace. New energy saving furnace ensures a reliable melting performance and continuous operation. It requires considerably low maintenance as well. Centrifugal drawing of the glass is made through the rotating device drilled with holes.
Curing Oven Blanket Stitching Machine Packaging Machine
Patented. The pretreated wool are cured in the curing oven, additives could also be added selectively, to produce the final products, such as board, blanket.


Blanket could be strengthened with glass fabric or wire mesh using blanket stitching machine. After stitching, the strength of blanket could improve considerably.


The finished products are packed for delivery or shipment on this machine.


Pipe Rolling Machine    
By combining the best technology we hold and profuse experience of industry involvement, we could also offer glass wool products with unrivalled insulation quality and better safety performance.


Pipe section of glass wool could be manufactured using pipe rolling machine.
