In the environmental sector where resistance to corrosion is required. Welding processing of PVC, PP, and fluoropolymer resins.

In the environmental field, high corrosion resistance is required for tanks and piping that come into contact with chemicals and corrosive substances. Particularly, leaks and damage can lead to environmental pollution, making reliable welding technology crucial. Our plastic welding processing accommodates various materials such as PVC, PP, and fluororesin, enhancing corrosion resistance. We use resin welding rods and can handle items from small to large. We also conduct water leak tests and air leak tests to ensure high quality. 【Application Scenarios】 - Chemical tanks - Wastewater treatment facilities - Chemical plants - Plating baths 【Benefits of Implementation】 - Improved corrosion resistance - Long-term product lifespan - Reduced risk of environmental pollution - Cost savings
