Problems encountered by customers
- A Colombian industrial manufacturer pointed out that hand and mechanical polishing left uneven “orange peel” texture and micropits on large areas of stainless steel, failing to meet hygiene and corrosion resistance standards.
- Welds and heat-affected zones require multiple grinding/polishing processes, and visible transition lines and residual abrasive pose a risk of contamination to food-grade equipment.
- Poor batch consistency: Up to 35% of parts require rework, causing production delays of 3-4 days per order.
Weshining’s solution
- Delivered a uniform, defect‑free ≤0.02 μm Ra finish across entire surfaces, including welded joints and complex curvature, with no orange peel or pitting.
- Reduced polishing time from 90 min to 12 min per large component – 87% faster, eliminating multi-stage handwork.
- Achieved 100% first‑pass quality; eliminated rework and contamination risks, increasing the manufacturer’s output by 40% without adding labor.
