How should I trade off tolerance vs cost on my Energy Storage battery busbar & cooling plate?

Update Time:2026/10/7

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.
