Automotive Engine & Powertrain Components Manufacturer
Challenge
Cast and machined engine and powertrain parts retained oil and coolant stains after washing, while steel-shot blasting left a dull, uneven finish—driving manual touch-ups, OEM visual rejections, and high equipment wear.
Solution
After analyzing materials and oil contamination, we implemented spherical glass beads (180–300 microns) as a single cleaning and cosmetic finishing step—removing oily residues, delivering a bright uniform finish, cutting hand cleaning by over 60%, and reducing visual rejections from 9% to under 1%.
