EXTRUSION LINE
In a tube or pipe extrusion line, a sealed water bath is acted upon by a carefully controlled vacuum to keep the newly formed and still molten tube or pipe from collapsing. For products such as plastic sheeting, the cooling is achieved by pulling through a set of cooling rolls.
Product Description:
Description of plastic pelletizing machine:
1. plastic granulate machine is the successor to plastic master-sub granulator.
2. plastic granulate machine is installed by “one line” shape, “right and left” shape and “T” shape, which is saving the work space.
3.This machine is different from waste plastic machine, such as PP, PE, HDPE. especially resolved the problem of high-density polyethylene granulation broken bars.
4. plastic granulate machine is matched with plastic crusher and granular cutting machine. While the waste plastic materials through crushing and washing, could be put into extruder without drying. But the die head of machine could be electric screen changer or hydraulic screen changer.
5. Simple process, advanced technology, automatic temperature control, national energy-saving patented heater, low power consumption, non-pollution, high degree of automation.
Process Flow of plastic pelletizing machine:
HDPE bottle →convey feeding→magnetic screening →forced feeding→degassing single screw extruder→hydraulic screen exchanger→material outing mould→degassing single screw extruder →hydraulic screen exchanger → material outing mould →water tank→drying system →cutting granulating unit →storage hopper
