Advantages of the line
1) Gravimetric dosing system for raw material handling is available, which can realize proportionally precise mixing of several types of raw materials components.
2) Advanced screw and barrel structure design can realize the raw material good plasticization and stable pressure and reliable extrusion
3) Hydraulic screen changer can effectively block the impurities from the raw material.
4) Imported Melt gearing pump is equipped to guarantee the raw material pressure more stable.
5) T die and online thickness scanner are equipped together to ensure the sheet thickness more uniformed.
6) The three roller calendars can adopt horizontal type, oblique type, vertical type or other angles type designs to meet different types of sheets extrusion. The driving system of the roller calendars can be common reduced motor control or servo motors control.
7) The online side trim granulator and pipeline conveying system can convey the side edges to the front extruder automatically.
8) Silicone oil coating unit can make sure the sheets are easily taken off from the thermoformed molds.
9) Sheets accumulator design for higher line speed
10) Worldwide famous assembly parts, such as SHINI, MOTAN, JC TIMES, NORDSON EDI, SCANTECH, NORD, MAAG, GEFRON, NSK, ABB, SIEMENS etc.
11) Effective energy saving technology with a very low energy consumption.
12) Whole line adopts fully automatic Siemens PLC touch screen control; the electronic control equipment effectively optimizes the whole line operation and achieves high quality and high output.
Sheet Applications:
Sheets are widely used for the thermoforming packing for food, fruit, medicine, electronics, toys,
chemicals, stationery, file bags, file folder, stationery supplies, clear bag, handbag, printing etc.
