To prevent the decline in productivity of the plastic pallet thermal welding process.

To prevent a decrease in productivity due to the adhesion of PP resin during the thermal welding process of plastic pallets.

Heat sealing (heat plate sealing) is a joining method where the parts of plastic components that need to be bonded are brought into contact with a high-temperature metal plate (heat plate) to temporarily melt the plastic surface, and then pressed together at the melted areas to integrate them. Some plastic pallets made of PP resin (polypropylene resin) are manufactured by integrating the upper and lower parts through heat sealing. The heat plates used in the heat sealing process of these plastic pallets are coated with fluororesin to utilize its property of being "non-stick," which helps prevent melted PP resin from adhering to the surface of the heat plate. However, over time, the fluororesin coating on the heat plate can become scratched or peel off, causing the resin to gradually start sticking. When resin adheres to the surface of the heat plate, the following problems can occur: - The resin is stretched from the adhered areas, compromising the appearance of the product. - Burnt resin that has stuck can mix into the joint area, leading to a decrease in the strength of the joint. - The need to replace the heat plate temporarily halts the production line, resulting in decreased productivity.
