Alumium-Plastic Compound Pipe Extrusion Line

General description Application & Suitable scale:
This production line is used to produce aluminum-plastic compound pipes and aluminum pipes in the methods of ultrasonic welding and co-extrusion. The aluminum-plastic compound pipe is widely in pipeline for transporting cold, hot water, acid, alkali, various liquid, fuel gas, oxygen, compressed air and so on.

Characteristics:
1. High automation, the production line is controlled by PLC to guarantee the precise of process parameters.
2. Low operation strength, easy to operate
3. The production line is specially designed and processed according to the material and production characteristics of aluminum plastic-compound pipe.

Process flow chart

The main part is high precision aluminum pipe forming line. First the coiled aluminum strip will become straight through the passive unreeling machine. Then it will be fed into pre-forming roller by positioning devices, the aluminum strip will be rolled into prototyping pipe. The pipe will be fed into forming section. After forming section, the precision of aluminum pipe is just normal. It must be shaped and positioned by sizing section to meet the required precision. The laminated parts of aluminum pipe will be welded by continuous ultrasonic welder to be sealed high- strength pipe.
Aluminum pipe welding section is the junction of branches. The other two branches are inner piper and bonding layer, outer pipe and bonding layer. It will pass the feeding, hot melting, extruding, and junction template. Then it will be distributed into inner pipe co-extrusion mould and outer pipe co-extrusion mould. The inner pipe is always connected with compressed air to check the pressure-retraining performance. After setting in cooling water tank, automatically blow drying and length measuring, it comes into printing section. The automatic inkjet printer is used to print the company name, pipe size and length on the pipe. The printed pipe will be hauling to double disk pipe winder to collect and coiled. After inspection, the coiled pipes are ready to sell.
