Store well
1. Store in dry places.The surface of corrugating rolls is not compact structure. The permeation and corrosion of water and steam will cause unusual falling off of coating.
2. Apply silicon oil. The silicon oil is valid for 3 months. If you don’t use corrugating rolls for a long time, silicon oil must be applied to the rolls regularly to avoid unusual falling off of coatings caused by the permeation and corrosion of water and steam.
3. Keep the surface clean. If you put the corrugating rolls in the warehouse, the surface should be cleaned and applied silicon for later use.
Flute Profile
Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement.
