Introducing a case where the issue of eliminating transfer to the film due to scratches on the roll surface and improving wear resistance for long-term use was solved with coating!
In the film sheet stretching process, even minor scratches on the roll surface are not permitted. Therefore, the "polishing" of the surface of the stretching roll becomes very important, and a high hardness that makes it difficult to scratch is required. We will introduce a case where our ceramic thermal spraying has solved this problem by improving wear resistance, reducing the transfer of scratches on the roll surface to the film, and enhancing release properties.
■Challenge
To eliminate the transfer of scratches from the roll surface to the film and further improve wear resistance for longer usage.
■Proposal
To improve wear resistance with a high hardness coating from ceramic thermal spraying, provide surface roughness polishing (from sub-mirror to super mirror) using NCI's unique finishing technology, and since recoating is possible after use, we proposed that we can finish and provide a reproducible surface roughness multiple times.
■Effect
The lifespan was extended, the repair cycle became longer, maintenance costs were significantly reduced, and it contributed to increased productivity, which was greatly appreciated.
