Model No.: LWYJ- 13
Features of screw elements
1. Screw is the heart of extruder. Material: Our screw material is the W6Mo5Cr4V2, with high Hardness, Wear Resistance and Red Hardness.
2. The hardness will be the same even the temperature reach 500-600º C. Design: The screw combination is building-block principle. The accuracy of the screw combination will decide the quality of the granules.
3. Accuracy: With CNC processing center.
Technical process of barrel
Quenching & Tempering → Rough Machining → pulling internal involute spline machine → Strand-cutting→ Milling machine or lathe(Semi Finishing Machining)→CNC Machining center→CNC threadgrinder(Finish machining) → vacuum quenching → Inspection
Packaging & Shipping
Package: Using Anti-rust oil processing, use stretch film cover extruder then wooden case against moisture damage.
Shipping: By sea or By express
