Process: Nitriding & Bimetal
Nitriding Layer Depth: 0.5 – 0.7 mm
Bimetal Screw Hardness: HRC > 60
Nitrided Layer Hardness: HV 960 – 1100
Screw Straightness: 0.015 mm
Chromium-Plated Screws: Chrome layer thickness 0.03 – 0.06 mm
Surface Finish: Ra 0.04 – 0.08 μm
Nitriding Brittleness: ≤ Grade 2
L/D Ratio: 1:33 – 1:42

Features & Performance:

Optimized material melting process to improve extrusion output and enable extrusion at relatively lower temperatures.

Good material homogenization achieved through controlled shearing in the barrier gap.

Melting and plasticizing process controlled, allowing only particles smaller than the barrier gap to enter the melt channel.
