Describe the surface condition you need
Bead blasting services are usually specified as part of a finishing scope. Identify the material, areas to process and the required appearance or customer finish reference. Do not rely on a generic phrase such as uniform matte finish if the drawing needs a measurable or sample-based acceptance criterion.
Protéger les caractéristiques fonctionnelles
Mark threads, bores, sealing faces, datum surfaces and other areas that should be masked or reviewed. Identify critical dimensions and whether they are checked before or after blasting. If a cosmetic sample controls appearance, attach the approved reference and state how it will be compared.
Include downstream requirements
State whether blasting is followed by coating, anodizing or another finish and identify the required sequence. Provide the drawing revision, material grade, quantity, inspection evidence and packaging instructions. Confirm that the part geometry and substrate are compatible with the requested finish.
