Stainless steel detail before and after polishing comparison

Problems encountered by customers

1. An Australian customer pointed out that hand polishing cannot reach the inner corners and blind holes of complex stainless steel parts, leading to the retention of hidden scratches and contaminants.
2. Excessive mechanical polishing can cause localized reductions in the thickness of thin-walled parts, resulting in decreased structural strength and leaks.
3. High rework rate (28%) and long processing cycles: each part takes 75 minutes to complete, and the surface finish varies between different batches.

Weshining’s solution

1. Achieved a uniform ≤0.02 μm Ra finish on all internal and external surfaces, including tight radii and blind holes – eliminating contamination risks.
2. Reduced polishing time from 75 min to 10 min per part – 87% faster.
3. Delivered 100% dimensional accuracy and first-pass quality, lowering total manufacturing cost by 35% for the client.
