No worries about the coating film peeling off and contaminating! The transparency of the PET bottle has also improved.
We would like to introduce a case study of surface treatment for molds used in blow molding PET resin. ■Challenges In the molds used for blow molding PET bottles, a coating was applied to improve release properties, making it easier for the resin to detach after molding. However, with the previous coatings, there were instances where the resin, softened by heat, would slightly adhere and remain, potentially leading to cloudiness in the PET bottles, necessitating frequent maintenance of the molds. ■Effects of the Adopted Coating We adopted our "Super Bi-Coat NYK-01-F05." This coating maintains performance characteristics such as film thickness precision and hardness comparable to previous bi-coats while improving release and slip properties during high-temperature molding. It reduces resin residue on the molds and enhances the transparency of the PET bottles. 【Key Points of the Case Study】 ■Purpose of Surface Treatment Reduction of work loss, stabilization of quality and operation ■Required Functions Non-stick and release properties, sliding and slip properties, wear resistance ■Adopted Treatment 'Super Bi-Coat NYK-01-F05' *For more details, please refer to the PDF document or feel free to contact us.
basic information
**Effects Achieved** - Improved release properties and slip characteristics when molding at high temperatures. - Reduced resin residue on molds, resulting in increased transparency of PET bottles. - Surface roughness remains almost unchanged after processing, eliminating the need for polishing the coating surface to achieve a mirror finish. - Higher hardness compared to standard Teflon coatings, eliminating concerns about coating delamination and contamination. *For more details, please refer to the PDF document or feel free to contact us.*
