A complete heat shrink tubing production line is a system that can produce heat shrink tubing from raw materials to finished products. Heat shrink tubing is a type of plastic tubing that can shrink in diameter when exposed to heat, and is used for various applications such as insulation, protection, sealing, identification, and decoration of wires, cables, connectors, terminals, and other components
- A pelletizer that can produce plastic pellets from raw materials such as polyethylene, polypropylene, polyvinyl chloride, or other polymers.
- An extruder that can melt the plastic pellets and extrude them into a continuous tube of desired diameter and wall thickness.
- A cross-linking unit that can apply radiation or chemical treatment to the extruded tube to enhance its thermal and mechanical properties.
- An expander that can inflate the cross-linked tube with air or nitrogen to create a larger diameter and thinner wall.
- A cooling&shaping unit that can cool down the expanded tube and set its shape and size.
- A cutting machine that can cut the cooled tube into desired lengths and widths.
- A printing machine that can print logos, texts, symbols, or other information on the surface of the tube.
- A tray winder that can pack the finished tubes into bags, boxes, reels, or other containers.
The production process of heat shrink tubing may vary depending on the type, size, and specification of the tube, as well as the quality and efficiency requirements of the manufacturer. Some production lines may have additional or optional equipment such as dryers, mixers, feeders, coilers, testers, or quality control systems.
A complete single wall heat shrink tubing production line is a system that can produce heat shrink tubing from raw materials to finished products. The process of producing heat shrink tubing consists of three steps: extrusion, electron beam irradiation, and expansion.
A dual wall heat shrink tubing co-extrusion line is a type of production line that can produce heat shrink tubing with an inner layer of adhesive and an outer layer of polyolefin. The co-extrusion process involves melting and extruding two different materials through a single die, forming a tube with a dual wall structure.
Some advantages of using a dual wall heat shrink tubing co-extrusion line are:
It can produce high-quality heat shrink tubing with excellent adhesion, sealing, insulation, and protection properties.
It can save production time and cost by eliminating the need for separate adhesive coating or encapsulation processes.
It can produce various types of dual wall heat shrink tubing for different applications, such as flame retardant, halogen-free, transparent, high temperature resistant, etc.
