Three-layer Co-extrusion Line

Brand potop
Product Detail

● Casting experiment of polymer materials.
● Research and parameter optimization of casting production process.
● New material casting performance test
● Masterbatch dispersion performance test and evaluation.


●Strength European standard integrated frame, 304stainless steel desktop with aesthetic design.

● All-in-one functions such as casting, trimming, rollingand winding etc.

● The power rollers are independently driven by servomotor, the roller speed is controlled accurately, and the synchronizationperformance is good.

● The height of the casting roll can be adjusted up anddown to meet the process requirement of casting forming of materials withdifferent solution strength.

● Hard chrome mirror roll with 304 stainless steel rollcore, high surface finish and no rust.

● High-quality and intelligent PLC touch screen, easy tooperate.   

● Built-in circulating water cooling, precise control ofcasting roll temperature.

● Optional air knife or electrostatic adsorber to improvethe adsorption of the solution and the roll surface.

● Optional waste collection device for wasterecycling.
