ENGINEERING FAQ

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Comprehensive Engineering Materials Library (50+).

Can you provide Material Test Reports (MTR) with heat lot numbers? +
Yes. 100% of our metals and engineering polymers come directly from certified mills with chemical and physical Mill Test Reports (EN 10204 3.1 certification).
Do you machine customer-supplied raw material? +
Yes. Clients may free-issue specialized raw stock or proprietary castings. We verify dimensional incoming stock and proceed with precision CNC machining.
Which material is best for high-strength, lightweight applications? +
Aluminum 7075-T651 offers exceptional strength comparable to many steels at one-third the weight. For extreme temperatures or corrosion, Titanium Grade 5 (Ti-6Al-4V) is the preferred standard.
What is your most popular plastic for precision prototypes? +
Delrin (POM-C) is our most popular plastic due to its superb machinability, low moisture absorption, and dimensional stability. For medical or high-heat use, PEEK is the premier choice.
