Frequently Asked Questions

How quickly will I receive engineering feedback?
Response time depends on drawing completeness, material requirements, and project complexity. After receiving drawings or project details, our team aims to provide an initial response within 1 business day and follow up with questions or next-step recommendations.
Do you support prototype development before production?
Yes. We support prototype-to-production programs for design validation, material evaluation, and fit testing. Prototype timing depends on material availability, construction complexity, and drawing readiness.
Can I send confidential or proprietary files?
Yes. An NDA (Non-Disclosure Agreement) is available upon request before sharing any confidential drawings or specifications. You can indicate your NDA preference on the inquiry form, and we will initiate the NDA process as the first step.
What file formats are preferred for engineering review?
We accept PDF drawings, DWG, DXF, STEP files, CAD models, BOMs, image files, and ZIP archives. For the most efficient review, 2D PDF drawings with dimensions, tolerances, and material callouts alongside 3D STEP files provide the most complete picture of your requirements.
Can Labelsun recommend materials for my application?
Yes. Material recommendation is a core part of our engineering review process. Based on your application requirements - including environmental conditions, substrate types, and performance expectations - we recommend appropriate material constructions from our qualified material portfolio.
