High degree of mechanization and automation, with stable product quality.

◆ Weld seam standards can be designed based on the stress-bearing characteristics of the product, ensuring the full utilization of the seam's integrity.

Our products boast excellent overall quality, with seamless integration between the weld and the base material, demonstrating superior corrosion resistance and leakage prevention.

◆ Reduces frayed edges, ensuring smooth and aesthetically pleasing seams

Internal welding is performed using an automatic long arm extrusion welding process, which is a crucial step in all manufacturing procedures. New PP/PPH/HDPE granules or welding rods, identical in nature to the drum, are thermally melted at the internal weld seam, becoming integrated with the drum base and body. The principle is the same as external welding, but the equipment differs.
