Does TFG USA provide Design for Manufacturability (DFM) reviews?

Yes. Our senior engineering team conducts comprehensive DFM evaluations prior to production to optimize part geometry, reduce material waste, choose the best process, and lower overall manufacturing costs.

What quality certifications and inspection reports accompany custom metal parts?

As an ISO 9001:2015 certified manufacturer, we provide Mill Test Reports (MTR 3.1), CMM dimensional inspection certificates, hardness testing, non-destructive testing (NDT), and full PPAP documentation upon request.

How does TFG USA manage global supply chain logistics for overseas buyers?

We handle end-to-end supply chain logistics including customs clearance, international freight management, tariff compliance, and door-to-door delivery with buffer stock inventory control programs.

Frequently Asked Questions

Global Procurement & Engineering FAQs

Answers to common questions from international buyers regarding tooling, quality assurance, and order execution.

How does TFG USA ensure strict adherence to technical drawing tolerances?

Every project undergoes a complete first-article inspection (FAI) and CMM verification against your CAD model before mass production. Our quality control engineers inspect parts at every stage of production to guarantee built-to-print compliance.

What metal alloys and materials do you manufacture?

We work with a broad spectrum of industrial metals including aluminum alloys (A380, A356, 6061), stainless steel (304, 316, 17-4PH), carbon steels, alloy steels, brass, bronze, zinc, and specialized heat-resistant alloys.

What are your standard lead times for tooling and sample approval?

Tooling and sample development typically take 3 to 6 weeks depending on part complexity and process type (casting vs. forging vs. machining). Expedited prototyping services are also available upon request.
