Series Co-Rotating Twin Screw Plastic Extruder

The SJ series co-rotating twin screw plastic extruder is structured with components in modular assembly way. It is able to meet the needs on processing different material through changing the assembly structure of the components, realizing its versatility. Moreover, the transmission case in progressive design and compact structure features high rotary speed, high torque output, stable operation and other strong points.

The barrel of the co-rotating twin screw plastic extruder uses the bimetal housing made of abrasion resistant alloy a301, whose rigidity is HRC60-64. The screw adopts the high speed tool steel W6Mo5Cr4Vo2 that is hardened in the vacuum to reach the rigidity to HRC58-62. Then the screw is able to bear large wear and keep long lasting.

Due to the digital temperature controller, the barrel realizes automatic temperature control whist processing. The head of the extruder is configured with thermocouple for measuring the temperature of the melted materials, as well as the pressure sensor for inspecting and controlling the extruded materials. This makes the product adapt to process different materials.
