Engineering & Tolerance Control

Practical Engineering Support & Print Specification Control

Sourcing machined parts overseas requires clear technical alignment. Our Korean manufacturing engineers bridge technical communication and work closely with our partner shops on DFM review and tolerance control in South Korea.

1. Collaborative DFM & Drawing Review

Our engineers review your 2D prints and 3D models together with candidate Korean shops to clarify critical tolerances, fits, threads, and surface finish callouts before quoting.

2. Right-Fit Selection from ~200 Pre-Vetted CNC Shops

We match your drawings to Korean shops whose machine capabilities, typical tolerance range, and inspection equipment fit your specific part requirements.

3. Inspection & Quality Alignment

We coordinate with the selected manufacturer to ensure parts are inspected against your print specifications—with ISO 9001 certified shops, CMM dimensional reports, and material certs available when required by your project.

Simple, Zero-Risk Benchmarking
