How should I trade off tolerance vs cost on my Energy Storage battery busbar & cooling plate?
Start from function, not the tightest number
For Energy Storage battery busbar & cooling plate where conductivity & corrosion resistance, tighten tolerance only on the dimensions that touch fit, seal or safety. LusterControl holds ±0.005 mm on stainless mirror parts, but we relax non-critical dims in the free DFM review so you pay for capability you actually use.
The trade-off in practice
- Tighter than needed: more machine time, more inspection, higher unit price, longer lead.
- Looser than function allows: scrap, rework, field failure, brand cost.
- Right-sized: lowest total cost with the risk designed out.
