One: Container extrusion and winding fabrication
The drums are formed through the extrusion process using spiral winding equipment. The system involves heating and melting PP or PPH granules, then extruding them and winding them around a steel mold to form the drum.
Advantages of extrusion winding:
Our production efficiency is 5-8 times higher than manual labor.
The product boasts overall quality, seamless structure, and excellent resistance to corrosion and leakage.
◆The product is flat and aesthetically pleasing, featuring a top-thin, bottom-thick design for reduced cost.
◆ Product dimensions and shapes are unrestricted.
◆The product is processed into granular material and has excellent anti-aging properties.
Section 2: External Welding Fabrication
External welding involves the use of imported automatic extrusion welding units to form a large weld seam in one go on the tank's area of maximum stress. The全新PPH granules identical in nature to the tank body are thermally熔融at the weld seam, becoming integrated with the tank bottom and body.
Bottom Welding Process Features:
Highly mechanized and automated, with stable product quality.
◆Weld joint specifications can be designed according to the stress-bearing characteristics of the product, enabling the overall integrity of the weld to be fully utilized.
The product boasts excellent overall quality, seamless integration with the base material, and superior corrosion and leakage resistance.
◆ Reduces frayed edges, providing smooth and attractive seams
Section 3: Internal Welding Fabrication
Internal welding is performed using an automatic long-arm extrusion welding process, which is the most critical step in all procedures. New PPH granular material, identical in nature to the drum, is thermally melted at the internal weld seam, integrating with the drum base and body as one. The principle is the same as external welding, but the equipment differs.
Internal Welding Process Features:
High level of mechanization and automation, stable product quality
◆Weld seam specifications can be designed according to the stress characteristics of the manufactured product, allowing for the full exploitation of the seam's integrity.
The product boasts excellent overall quality, seamless integration with the base material, and superior corrosion and leakage resistance.
◆ Reduces fraying, seams are smooth and aesthetically pleasing
Section 4: Pipe End Installation and Fabrication
Pipe end installation is the final process, akin to a scaled-down version of bottom welding. It involves using an imported small automatic extrusion welding unit to weld the pipe and flange into shape, then using a boring tool to open the corresponding diameter in the tank body, and finally employing the German MUNSCH portable extrusion welding.
Pipe end installation process features:
Highly mechanized and automated, with stable product quality.
◆The pipe outlet weld is integrated with the tank body, featuring high welding strength.
◆ Reduces burrs, ensuring smooth and aesthetically pleasing welds
