In the "thermal staking process" for the manufacturing of precision optical devices and resin components, issues such as appearance defects caused by resin stringing and resin debris sticking to jigs, as well as frequent jig replacements and downtime due to early wear of conventional release coatings, have become significant challenges. ■ High-Durability Fluoropolymer Coating "Thermo Pro Release" This surface treatment solution combines excellent release properties and heat resistance with robust film characteristics that withstand harsh thermal cycles and physical loads. Compared to conventional fluoropolymer coatings, it dramatically enhances adhesion to the substrate and wear resistance, maintaining release performance for extended periods even at high temperatures. ■ Implementation Effects - Overwhelming Longevity Durability has significantly improved by 5 to 20 times compared to conventional coatings from other manufacturers. - Operational Performance Jigs that had a limit of 300 shots can now operate non-stop for 4,000 shots, and jigs with a limit of 2,000 shots can now reach up to 20,000 shots. - Cost Reduction By reducing the frequency of jig replacements and the costs of re-coating and spare management, total maintenance costs are significantly cut.

In the "thermal crimping" process, which does not use adhesives for fixing lenses to resin tubes, the manufacturing site suffers from appearance defects and reduced yield due to "stringing of molten resin" and "adhesion of resin debris to jigs." When resin adheres and accumulates on the surface of the jig due to heating and pressurization during crimping, the detached resin debris can stick to the product, causing critical quality issues. Even release coatings designed to prevent these problems become meaningless if they wear out or degrade prematurely due to high-temperature and high-load thermal cycles. Our high-durability fluoropolymer coating "Thermo Pro Release" is a surface treatment solution that achieves the highest level of "non-stick (release)" and "wear resistance" against molten resin. ■ Benefits in terms of quality - Thorough prevention of stringing and adhesion Excellent slip and release properties ensure smooth separation of the jig after thermal crimping. - Dramatic improvement in yield Prevents the accumulation of resin debris, significantly reducing appearance defects in products. - Long-lasting performance The coating is resistant to wear even in high-load environments, maintaining its high release performance over an extended period.

Have you faced the challenges of 'trying various surface treatments in the process improvement of heat staking and heat welding, but the coating peels off quickly under high temperature and high load' and 'not being able to find a surface treatment compatible with the resin of the counterpart material'? The causes of failure in surface treatments for heating jigs lie in the lack of coating design tailored to the specific thermal cycles, load conditions, and the resin used in the process. Our high-durability fluoropolymer coating, 'Thermo Pro Release,' is a heat process specialized solution that leverages our proprietary formulation technology for flexible coating customization and robust wear resistance. [Key Features] We possess our unique 'Release Performance Evaluation Testing Machine' designed for heat staking and heat welding. This allows for pre-validation that traces actual conditions in the field (temperature, applied load, contact time, etc.), enabling highly reliable specification selection. [Strengths of Our Proposal] ■ Proprietary Formulation According to Resin Setting the optimal release and hardness balance for the work material (counterpart material). ■ Pre-validation System Testing before implementation is possible with our unique evaluation testing machine. ■ Dramatic Longevity By enhancing adhesion strength, we achieve durability 5 to 20 times greater compared to conventional fluoropolymer coatings.
