Fabrication Workshop
Industry: Heavy Fabrication
System: Sand Blasting
Scale: Job-work
Challenge
Frequent rework caused by uneven pre-paint preparation quality across fabricated structures.
Solution
Process redesign using suitable blasting setup, media flow controls, and improved dust management.
Outcome
Higher paint adhesion consistency and reduced rejection in downstream inspection cycles.
Stage 1Root-cause review of rework and adhesion failures.
Stage 2Surface profile targets aligned with coating process.
Stage 3Controlled blasting runs and dust extraction tuning.
Stage 4Standard operating procedure shared with shop team.
