Wholesale China Thin-Wall Efficient Mirror Roller Manufacturers Suppliers – Roller for Bi-Oriented Stretch Film Production Line – JWELL

Jwell Machinery Co., Ltd. not only focuses on the design and manufacture of the roller of plastic plate sheet, meets the requirement of the clients, but also supplies the high quality roller for the plastic film business area.
We import the foreign advanced roller manufacture technology, supply the high quality roller for the machine of casting film and stretch film. Such as chill roller, stretch roller, preheat roller, pull roller, corona roller, rubber roller, TEFLON roller etc.
The roller rotate in higher speed when produce the plastic film, so that high precision of the roller dynamic balance is important particularly. Our specified large dynamic balance testing equipment and various balance process can ensure these request effectively.

According to the strict molding request of final film product to the temperature error on the roller surface, The roller which has the spiral inner flow channel is a high-tech product, it has a very good heat exchange ability and this roller can reach the minimum temperature fluctuation which is allowed in production.
