Production Process

Clean and Inspect after receiving old rolls⇒ Give suggestion for the flute height ⇒Machining bearing position⇒Finish grinding ⇒Testing flute profile⇒Hard chrome plating ⇒Flute profile testing⇒Polishing ⇒ Final testing⇒Pack

Adjust well

1. Inspect the balance of corrugating roll regularly, at least once a month.

2. Inspect the gap among corrugating roll, glue roll and pressure roll to avoid abrasion.

3. When installing corrugating rolls, mind the small gap between corrugating rolls and suction hood which will cause abrasion of corrugating rolls and aluminum plate from suction hood.

4. The copper knives will loosen with the movement of machine. The knife in “T” position will scratch the coating on two sides of grooves. So fix the cooper knives regularly.

5. In the premise of assuring corrugated board quality in real production, it’s better to use smallest oil/air cylinder pressure both of corrugating roll and pressure roll.

6. When changing wide width to small width in real production, reduce oil/air cylinder pressure both of corrugating roll and pressure roll accordingly to avoid abnormal abrasion caused by excessive pressure. Especially the direct abrasion between corrugating rolls and pressure roll in paperless areas will cause falling off of coatings.
