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 quality variability.
2. Utilizing ultra-high-pressure automatic pressure-relief extrusion equipment, a wide range of bar profiles can be produced: This fully automated 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 grinders with a higher polishing rate to rapidly remove the damage layer generated during polishing, thereby enhancing surface finish and attaining a mirror-like appearance. Precision tolerances for fine-ground bar stock: diameter tolerance D ≤ ±0.01; length tolerance L ≤ ±0.5.
4. Stable mechanical properties, easy weldability, excellent wear resistance, and high impact resistance.
