We will introduce a case where surface treatment technology solved the issue of stringing in welding molds.
■Request We want to eliminate stringing that occurs on the heating plate during the thermal welding of polyethylene containers. We aim to reduce product defects caused by stringing without changing the takt time and to decrease the frequency of replacing the heating plate. ■Criteria for Processing Selection As a result of considering cost-effectiveness, we require a lifespan that is twice that of the current coating. ■Achieved Effect By adopting CHC technology for the coating, we have successfully achieved both release effect and longevity. *You can download a PDF summarizing the product information.

basic information
■What is CHC Technology? CHC technology is a method that prevents the reduction of coating strength in high-temperature environments, which is a weakness of fluororesins, enhances durability, and maintains excellent release properties in environments above 200°C. ■Features - Non-stick properties equivalent to PTFE and PFA - High film hardness at temperatures above 200°C (compared to PTFE) *Based on internal testing ■Applications - Resin welding plates - Resin molding molds - Heater plates *For product details, please download the PDF or refer to the link below. *For more information, please contact us.

Applications/Examples of results
■Achievements in Surface Treatment Adoption - Achievements in high-temperature release and high-temperature lifespan in the thermal welding process of filter cases - Achievements in sustaining the release effect from processing thermal welding plates for three times longer than PTFE coating - Achievements in solving the "peeling" and "blistering" issues of fluorine coating on resin product welding plates - Achievements in eliminating adhesive adhesion and high-temperature peeling that could not be resolved by PTFE coating
