Extruder&Expander of Single-wall Heat Shrinkable Tubing
Extruder&Expander of Single-wall Heat Shrinkable Tubing
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process.
Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). It can be done with hot or cold material. Commonly extruded materials include metals, polymers, ceramics, concrete, modelling clay, and foodstuffs. Products of extrusion are generally called extrudates.
However, when the tubing is heat-shrunk, its thickness will increase, which will in turn increase its overall dielectric withstanding voltage. Good-quality tubing can expand to more than twice its size.
Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.
The main components of heat shrinkable tubing extrusion production line: Extruder — Extrusion Die — Cooling and Setting Water Tank — Tractor — Winder
The main components of the heat shrinkable tubing expansion production line: Unwinding stand—tube blank feeding–glycerin heating box–die positioning–vacuum control–water cooling–traction output
The extruder models are: SJ-45 extruder, SJ-55 extruder, SJ-65 extruder, SJ-75 extruder, SJ-90 extruder.
Heat shrinkable tube extrusion die: within a certain range, different specifications of molds can be replaced to produce products of different specifications.
There are two types of cooling and shaping water tanks: submerged cooling water tanks and vacuum cooling water tanks. The submerged cooling water tank is mainly used for extrusion cooling and shaping of small-sized heat shrinkable tubes. The vacuum cooling water tank is mainly used for extrusion cooling and shaping of large-sized heat shrinkable tubes.
There are two types of tractors: The pair of roller traction machine (composed of 2 pairs of rubber rollers) is mainly used for extrusion traction of small-sized heat shrinkable tubes, The crawler tractor (composed of 2 rubber belts) is mainly used for extrusion traction of large-sized heat shrinkable tubes.
Rewinding machine: large diameter rewinding disc, to prepare for the next step (preparation for electron accelerator irradiation)
The extrusion production line is equipped with a fully automatic vacuum feeding machine.
Equipped with drying hopper, the models are: 25KG, 50KG, 75KG, 100KG
Unwinding stand: Pneumatic can be adjusted up and down, and the unwinding disc can rotate freely on it.
The feeding part of the tube blank: the transmission part is driven by the motor, and the rubber roller feeds the tube blank into the glycerin box
Glycerin heating box: electric heating of glycerin, heating the tube blank, the tube blank reaches a molten and high elastic state
Conveying part: the transmission part is driven by the motor to realize the continuous and uniform conveying of the tube blank in the glycerin box
Mold positioning part: used to install the expansion mold
Vacuum control part: control the vacuum size of the mold
Water cooling part: control the amount of water in the mold and cool the expanded heat shrinkable tube
Traction output part: the motor drives the rubber roller to pull the expanded heat shrinkable tube for output.
