Adhesive problems with blades that occur in production equipment, such as cutting adhesive films and tapes. Solved with a non-stick coating for the blade.
Are there any issues with adhesive sticking to the "cutting blades" of production equipment, impairing cutting performance or contaminating products? ■ Obstacle to Automation For process automation, it is essential that no human intervention is required and that operations are continuous. If phenomena occur where adhesive materials adhere to the blades, it becomes difficult to automate that line. ■ Increased Cleaning Frequency If frequent cleaning of the blades is necessary, production may not be achievable within the expected time frame, leading to decreased production efficiency. Additionally, increased working hours due to cleaning can raise costs and heighten concerns about worker safety. ■ Adhesion to Products, Product Contamination If adhesive or materials stuck to the blades adhere to the next product being cut, it can result in defective products or necessitate repairs in subsequent processes. Furthermore, if the cutting blades become dull, it can disrupt the cutting shape and cause issues. Yoshida SKT offers coatings that can resolve such troubles. ▽ Click here to apply for a collection of case studies on cutting process improvements and a trial set ▽

【Case Study】 Continuous Cutting Process of Multi-layer Film ■Problem There is a layer of adhesive on the first layer of the film, causing adhesive to stick to the rotary blade. This adhesion leads to cutting defects and line stoppages. ■Challenge To create a cutting tool that can continuously cut without adhesive sticking to the rotary blade, a coating that prevents adhesion with excellent release properties and durability was required. Initially, a Bi-Coat® with superior durability and release properties was selected. The film thickness was about 10μm, and there was no visible change in the appearance of the tool, but when tested, the cutting performance deteriorated to an unusable state. Next, a silicone-based coating that would have minimal impact on the blade shape was proposed, but due to the high adhesive strength of the adhesive layer in the multi-layer film, while cutting was possible, adhesion problems occurred. ■Adoption Process and Effects The rotary blade presses the blade edge against the film and cuts with pressure, resulting in minimal friction with the product. Therefore, MRS-004, which has excellent release properties and tackiness despite being a thin film, was proposed. As a result of testing, it was possible to maintain the cutting performance without any change in the blade edge shape while continuously resolving the issues.
