Extruder machine screw and barrel
This extruder screw diameter 16mm or 20mm is an exaple for extruding plastic for lab or school.
Customised is welcomed. Extruder screw is the field of polymer processing.
Following questions will be needed.
1, what material of plastic you will apply? This will detemine the design of screw.
2, what product you want to make?
When a similar drawing provided, the extruder will be made basing on the drawing.
The drawings for the pictured.
Aspect ratio: L / D = 15-40
commonly material: 38crMoAIA,Qualitative. Nitriding, surface hardness: HV ≥ 900 Nitriding depth: 0.5-0.8mm
The following are the same as the "
surface WC / CO overall spray welding, can effectively improve the service life of the screw
Extruder screw structure features:
1. Simple structure, low price
2. Suitable for plastic extrusion of polymers, suitable for extrusion of pellets. The shear degradation of the polymer is small, but the material has a long residence time in the extruder.
3. Easy to operate, process control is simple.
4. Has a good mixing plasticizing capacity, the material in the extruder to stay a short time, suitable for powder processing.
5. Large output, extrusion speed, low energy consumption.
