Key Standards and Concepts for Metal Part Surface Roughness
Here’s an overview of key standards and concepts for metal part surface roughness. Core Standards Organizations: ISO (International Organization for Standardization): The primary global source. ISO 21920-1:2021: Geometrical product specifications (GPS) — Surface texture: Profile — Part 1: Indication of surface texture in technical product documentation (Replaces ISO 1302:2002). This is the fundamental standard for specifying roughness symbols, parameters, and […]
Process Comparisons of Sand Blasting & Bead Blasting
Media & texture Sand uses sharp, angular particles, which cut into surfaces. This makes it ideal for aggressive cleaning but also more likely to cause surface damage. Beads are round and impact the surface gently. They clean and polish without removing much base material. Pressure & speed Sand blasting uses higher pressures, making it faster […]
