Structure and features
There is an exhaust system so as to improve quality of products.
There is an exhaust system so as to improve quality of products.
The screws are conical so that melt can be extruded in temperature.
There is an automatically circulated cooling and adjusting system at the core of screws,thus improving efficiency and ensuring reliability.
Resistance heater quipped with the cylinder,ensuring that heat is transmitted evenly and rapidly.
Frequency conversion and stepless speed regulation,thus ensuring steady speed and facilitating speed regulation.
Japan-origined Omron temperature control meter,ensuring high precision in temperature control.
Over-current protection device,ensuring reliable protection.
38CrMoA1A. Nitrogen Treated, the hardness of surface: HV>=900, the deep of Nitride layer: 0.5-0.8mm.
Base material 38CrMoA1A. Screw-flight surfaced, double-alloy welded, thus extending the life of screws.
