Material Preparation: We select thick 304/316L stainless steel plates, ensuring uniform thickness and impurity-free material.

One-Piece Stamping Molding：The entire stainless steel plate is stamped into the tank body in one piece using a large hydraulic press, creating a seamless structure.

Head Processing and Welding： The head is stamped separately, and after aligning with the tank body, circumferential welding is applied.

Interface & Structure Installation： Flanges, valve interfaces, supports, and forklift slots are welded and the weld seams are polished.

Strict Testing：Water pressure and air-tightness tests are conducted to ensure the product meets factory standards.

Material Processing: Polyethylene material is selected and mixed thoroughly.

Extruded Preform：The material is heated and extruded through the machine, aligning with the mold entrance.

Molding & Blowing：The mold is closed, and high-pressure air is injected into the preform, causing it to expand and tightly fit the mold walls.

Cooling & Unmolding：The mold is cooled with water for 1-3 minutes before removing the tank body and trimming excess edges.

Post-Processing & Testing：Valves and accessories are installed, the product is tested, and the frame and inner liner are assembled before final inspection.
