FEATURE:

1. Extruding unit can be moves forward and backward, cooperated with embossing unit fluctuate, which will be more convenient for changing roller and clean the T-DIE and increase the operational satety.

2. Screw is of Italy design which enhances the plasticizing capability, it incorporates with European imported static mixer to ensure melting of resins, homogeneous color and increase the quality of the sheets.

3. T-die is from EDI America, which enables the sheet thickness to be more even.

4. The gear is made in Italy, it has advantages of high efficiency, frictionless and low noise.

5. Temperature control uses SCR system, tolerance of temperature is ¡À1 degree. It may precisely control plasticizing processes, sheet thickness, flatness and neatness.

6. Embossing roller of diameter 350 mm and two-loop coiling system incorporates with microcomputer auto temperature system will precisely control temperature of embossing roller and cooling roller so as to make sheet to be flat and neat, keeping the thickness homogeneous.

7. The cutrer ueses microcomputer and servo-motor control to enable sheet length and quantity to be accurate. The speed is up to 15m per minute.

8. Electric contrl system completely uses international standard with quality, renowned parts and components. And it is synchroized computer comtrlooers to operate the production line safely and conveniently.  

 

1. From these configuration, you can see that Donghe extruder is more efficient, screw Diameter is smaller, while output capacity is much higher. According to users of Donghe PP extruder (stationery manufacturers), this extruder saves electricity cost over 30,000 USD per year, comparing with other 'cheap' extruders. In China, all top 10 stationery manufactures are using Donghe extruding machines, in Europe, Donghe PP extruder has 9 users, including factory of ESSELTE in Poland. ) 

2. Donghe adopts Italian made screw, the L/D rate of which is 36:1, so the quality of output PP film/sheet from Donghe Extruder is much better, more suitable for stationery producing.  We have 7 zones to control Die temperature, to guarantee flatness of the film/sheet.  

3. Donghe has bought German patent and applied to the embossing roller, which guarantee the extruded  film with uniform thickness both on the edge and in the central part , and same depth of the embossing  pattern.  (Film extruded by traditional extruder is thicker in the middle and thinner on the edge.) 

4. Donghe extruder has CE certificates. It's energy saving, more safer and with higher working efficiency.   

5. Electronic parts of our extruder are world famous brand, which guarantees stability of working, saves labor cost and maintenance cost.
