よくある質問
After receiving your CAD files or drawings, our engineering team reviews key factors such as geometry, tolerances, wall thickness, tool accessibility, radii, threads, and material requirements.
If potential manufacturing issues are identified, we provide practical recommendations on design optimization, tolerances, machining processes, and material selection to help ensure stable and repeatable production.
This early review helps reduce design changes, control manufacturing costs, and improve production efficiency before machining begins.
Lead times depend on part complexity, tolerance requirements, material, surface treatment, and order quantity. For most prototype and small-batch projects, production can typically be completed within a few working days, while complex components or multi-process projects may require additional time.
For urgent projects, expedited production may also be available. To provide an accurate lead time, simply send us your 2D drawings or 3D files, material requirements, and quantity. Our engineering team will review the project and confirm the estimated lead time during the quotation process.
Yes. We can provide material certificates, inspection reports, and other quality documentation based on project requirements. Our inspection records cover key dimensions, tolerances, hardness, and other specified requirements to support full quality verification and traceability.
The cost depends on factors such as part geometry, material, tolerances, surface treatment, machining processes, and order quantity. We provide competitive pricing based on your specific requirements while maintaining consistent quality.
