Double barrel screw parameters and material requirements
Double barrel screw parameters and material requirementsThe effective service life of the double barrel screw is much longer than that of the ordinary nitriding barrel, increasing the wear life.
Double barrel screw
Double barrel screw parameters:
Adhesion strength: over 10000psi;’
Surface finish: screw surface is less than 0.04um;
Surface hardness: HRC59-69 degrees;
Specifications: Ф15mm-Ф300mm;
Scope of application: pipe extrusion;
Straightness: 0.015mm/m;
Surface hardness: Hv900~1060.
Double barrel screw
Double barrel screw structure:
This type of screw has a measuring section with equal length and equal depth of 4-60. The screw head pressure and material flow are relatively stable, so the quality of the extruded products is good. It is widely used in polyvinyl chloride, polyolefin and engineering plastics. The feed section of this type of screw is equidistant and equal depth, and the screw groove depth of the compression section gradually decreases.
Double barrel screw
Requirements for the material of double barrel screw:
1. Wear resistance, long life;
2. High temperature resistance, no deformation under high temperature;
3. Corrosion resistance, the material is corrosive;
4. The residual stress after heat treatment is small, the thermal deformation is small, etc.;
5. Good cutting function;
6. High strength, high torque and high speed are acceptable.
