What is melting? An explanation of one type of resin melting, heat plate melting, and non-adhesive surface treatment.
CHC (Ceramic Hard Coat)
We will also introduce non-stick surface treatments that are essential for solving the disadvantages of various types and methods of melting and heat plate melting.
■What is Resin Welding Resin welding is one method of joining resins using heat. ■Types and Methods of Welding - Ultrasonic Welding A method that uses ultrasonic vibrations for joining. - Vibration Welding A method that uses frictional heat generated by vibrations for joining. - High-Frequency Welding A method that uses self-generated heat from high frequency for joining. - Laser Welding A method that generates heat using laser light for joining. - Heat Plate Welding A method that melts materials using a heated plate for joining. ■Advantages and Disadvantages of Heat Plate Welding Heat plate welding can accommodate a wide range of part sizes and can securely weld even three-dimensional shapes, making it suitable for joining components that require airtightness. On the other hand, it cannot be used if electronic components are present, and there are disadvantages such as excess material when welding, resin sticking to the heater, and stringing. ■Surface Treatment to Prevent Resin Sticking and Stringing to the Heat Plate One method to prevent resin sticking to the heat plate and stringing, which are among the disadvantages, is surface treatment.

■What is CHC Technology? CHC (Ceramic Hard Coat) is a new type of fluoropolymer coating that achieves both non-stick properties equivalent to standard fluoropolymer coatings and high film hardness at elevated temperatures. ■Examples of Surface Treatment Applications - A case where high-temperature release and long-term durability were achieved in the thermal welding process of filter cases. - A case where the release effect from processing thermal welding plates lasted three times longer than PTFE coatings. - A case that resolved the "peeling" and "blistering" issues of fluoropolymer coatings on resin welding plates. - A case that eliminated adhesive adhesion and peeling at high temperatures, which could not be resolved with PTFE coatings. ■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 more details, please click on "PDF Download" or feel free to contact us.
