Product Features
1. Utilizes low-pressure sintering technology for stable and reliable quality: the sintering pressure can reach 100 kgf, effectively eliminating internal porosity in the alloy to produce green compacts with excellent density, high hardness, and high strength. An advanced temperature-control system further minimizes variations in product quality.
2. Utilizing automated pressure-relief extrusion equipment, a wide range of bar profiles can be produced: The fully automatic extrusion line, imported from Germany, allows pressure to be adjusted according to specific requirements, facilitating the production of various bar types.
3. High-precision fine grinding of bar stock to achieve a mirror finish: Utilizing CNC grinding machines with a higher polishing rate, this process rapidly removes the damage layer generated during polishing, significantly enhancing surface finish and attaining a mirror-like appearance. The dimensional tolerances for precision-ground bars are as follows: diameter tolerance D ≤ ±0.01 mm; length tolerance L ≤ ±0.5 mm.
4. Stable mechanical properties, easy weldability, excellent wear resistance, and good impact resistance.
