Common coater scrapers are ceramic scrapers, steel scrapers, alloy scrapers, etc. The following focuses on their characteristics:

Ceramic Scraper for Coating Machine:

Relatively ideal at low speeds
Life is relatively short at high speeds
Controllability is worse than alloy scraper
CD Banner Control Can't Reach Ideal State

Coating machine steel scraper:

It is difficult to maintain the original angle of the scraper for a long time.
It is relatively difficult to control the amount of coating.
It is difficult to guarantee the quality of coatings.

Alloy Scraper for Coating Machine:

At present, the scraper is widely used.
Low, medium and high paper locomotive speed can be applied.
Abrasion resistance, good elasticity and high hardness.
Comparisons can improve the quality of paper products
Relatively long life and increased production capacity
It has better printing performance and saves cost.
Strong operability (standardization is very important in operation)
