Twin Conical Screws Extruder

Product presentation



☞ Twin Conical Screws Extruder

The conical twin-screw extruder is an efficient mixing and extrusion device. The machine has the characteristics of small shear rate, easy decomposition of materials, uniform mixing of plastic, stable quality, high output, wide application range and long life service The counter-rotating conical twin screw extruder is ideally suited for quality control, product development and research applications. 
All the screws allow a uniform forward flow regardless to the degree of flight filling, feeding uniformity, polymer flow characteristics, or back pressure. The counter rotating chamber produces a milling action between the screws similar to a calendering process.




High Efficient Single Screw Extruder

Nigh efficient single screw extruder is developed by adopting German latest advanced technology. Screw optimizes composing separate type screw and mixing parts. Barrel optimizes composing groove barrel and lengthened feeding segment.

There is advantage as following by using separate type screw and groove barrel together:

    →It's optimized during material melting process. Thus get more extrusion throughput. it is realized extruding melt material in low temperature.

    →Cutting function is caused through separate clearance and it makes material equal well.

    →It's controlled during melt plasticization process. Therefore only granules that smaller than separate clearance can enter melt channel.

    →Wide manufacture range for different materials. It's suitable for all kind of polyolefin materials and especially for material for HDPE, PP, and ABS pipe.



 Twin Parallel Different Direction Double Screws Extruder

Model SJP serials twin parallel screw extruder is a kind of special equipment for extruding of PVC powder. With different sorts of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe material, profiled material, board material, sheet material, bar material and granulation.

      →The screw has applied oil system. Barrel is cooled by special wind cooling system. The control system has applied computer control. 
      →According to customer's requirements, most reasonable screw can be made so as to achieve best plasticity state and material quality. 
      →The screw is made by high precision special digital screw miller, extruding property can be highly harmonized. It has firstly introduced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut. 
      →The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. 
      →The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, temperature control tolerance can be±1℃ .
