How Tolerance Affects Cost

Tighter tolerances require more machining control, inspection effort, and cycle time, which increases cost.

Recommended Tolerance Planning

Apply tight tolerance only on critical features, and keep non-critical dimensions at practical ranges.

Typical Project Workflow

1. RFQ & DFM Review
We review files and propose practical manufacturing options.
2. Quotation & Confirmation
We align process, lead time, and quality requirements.
3. Production & Inspection
Parts are manufactured with in-process and final checks.
4. Packaging & Delivery
Export-compliant packaging and global shipment coordination.
Project workflow from quote to delivery

FAQ

Question

Can all dimensions use very tight tolerances?

Technically possible for some parts, but usually unnecessary and costly for non-critical features.

Question

How do you verify critical dimensions?

We define measurement methods and checkpoints for key dimensions and keep records when required.

Question

Can tolerance be optimized at quotation stage?

Yes. Early review helps reduce manufacturing risk and avoid over-specification.
