The Step Between Forming and Coating That Most Factories Skip.
Burrs from wire cutting. Rough spots on welds. Surface oxidation. These defects cause PVC coating to peel, rust to form prematurely, and customers to complain. The WHB-300's 4-station progressive brush system removes all of it in one pass — from coarse deburring to fine polishing — leaving a surface that coating adheres to perfectly.
| Station | Grit | Purpose |
|---|---|---|
| 1 — Deburr | 120 | Remove heavy burrs, sharp edges |
| 2 — Smooth | 240 | Flatten weld spots, even surface texture |
| 3 — Refine | 400 | Fine scratch removal, prep for coating |
| 4 — Polish | Felt | Final luster, bare-metal presentation ready |
