Extruder Screw
About the extruder screw,there are many models and varieties.
So, there are single screw, twin screw, three screw, food extrusion screw. In addition, different raw materials, screw types are also different.
So,Learn more about extruder screws.
Extruder single screw
① Production line single screw: Application: sheet, cast film, blow molding, panel, etc extrusion.
② Injection molded single screw: use it in various injection molding machines.
③ Rubber extrusion screw: rubber, tire, seal extrusion equipment.
④ Non-standard custom class: food, chemicals, other special industries.
The construction is simple, therefore, only need to know the field of use, the materials of use (example: PP PE PET ,ect), and L/D.
Custom machining or OEM: need drawings or samples.
Screw data
| Type | Material | Diameter (mm) |
| Single screw | 38CrMoAL / Alloy | 20~350 |
| Double screw | C12MoV / 38CrMoAL / W6Mo5Cr4V2 | 16~280 |
Nitride steel 38CrMoALA has high surface hardness and soft core after heat treatment. Have certain corrosion resis-tance, strong toughness, not easy to crack, Suitable for mild corrosive materials, high cost performance.
High speed tool steel W6Mo5Cr4V2 adopts vacuum quenching, which has a strong hardness and strong resistanceto abrasion, lt is suitable for high filling materials, including engineering materials and color mastermaterials.
Extruder twin screw / three screw
Adopt building block system, combine multiple screw element together, connecting together with screw shaft. Thus, obtaining a complete set of screws.
Therefore, the screw element arrangement order is different, tens of thousands of variations. So,Twin screws are more complicated.
Therefore, this kind of screw ,more use it for plastic granulator.
It is easy to adapt to the development of various raw materials and formulations. Perfect compound and plasticizing effect, and good cleaning ability, and low maintenance cost.
