1.brief introduction
SJ series single screw extruder is used for processing of PP PE PET ABS etc plastic material.Different material need equip corresponding screw.
SJ series extruder cooperate with downstream equipment and die head ,it can produce plastic profile,sheet,pipe etc plastic products.
this extruder have advantages of high-speed extruding,well-mixing,high precision temperature control,low melting temperature,stable running etc.which guarantee the saving of enegy and high qualilty finished products.
2.The characteristic of machine
A)The barrel and screw
The barrel and screw is made of high quality 38CrMoAlA alloy steel,the surface of which is done nitriding treatment,the thickness of nitriding is 0.5-0.8mm,the roughness degree of barrel inner wall Ra≤0.4um ,the hardness of barrel ≥950HV . It has high hardness,anti-wear and anti-rust etc advantag.The barrel is slotted and equipped with prolonged cooling water sleeve and force feeding device ,which can feed material effectively.
B)Gearbox
This machine adopt high strength hard gear face gear box,the body adopt bevel wheel driving,gear is made from 20CrMoTi and it is treated by cementite and grinding,the distribution box is made from 38CrMoALA and is treated by nitriding,the shaft is made from 40Cr.the distribution adopt SKF bearing.The force lubricating system and force cooling system is equipped.The gear box have advantages of little size,beautiful appearance,high precision,high strength,long working life and low noise etc.
C) Electric system
1)Famous brand frequency drive-FUJI or ABB or DELTA
2)RKC Japan RKC temperature control meter
3)Schneider breaker contactor,button,indicator
4)Taiwan connecting terminal
