Instrument features:

1.Extruder is driven by servo motor of international brand, with stable plasticization and good consistency;

2.Extruding device: Barrel and screw are the key parts of this machine, where plasticizing and extruding of materials are carried out. The barrel and screw are made of high-quality nitrided steel 38crmoala, and the surface has been treated with one-week gas nitriding, which has good mechanical properties such as high hardness, wear-resistance and corrosion-resistance, and greatly prolongs its service life.

3.The barrel heating of this machine adopts cast aluminum heater with stainless steel wind cover, which is beautiful and energy-saving, with good heat-resistant performance, long service life, even heat transfer, and easy to be replaced; the fan cools through the set channel (automatically opens the fan for cooling in case of over-temperature), which has a good cooling effect.

4.Transmission device: Drive motor and reducer directly connected to the reducer output shaft and screw connection, drive screw rotation. The transmission device has a compact structure, smooth operation and strong bearing pressure.

5.Emergency stop device and all kinds of safety protection, to protect the safety of operators;

6.Highly intelligent, easy to operate.
