FAQ

Frequently Asked Questions

These are our common FAQs. If you need specifics: such as machines, quoting, lead time, shipping, quality process, packaging, or payment, please email info@aerocncparts.com.

Our engineers will reply with clear, detailed information.

Can tray table hinges be produced to match specific seat layouts?
Yes. We can customize hinge geometry, material grade, and mounting dimensions to ensure seamless integration with various seat and cabin configurations.
How do you maintain consistent hinge motion in high-use environments?
By combining dry-film lubrication with precision-milled pivot points, it ensures silent operation and minimal friction over thousands of cycles.
What inspection methods are used during production?
Each hinge undergoes CMM verification, microscopic surface inspection, and functional testing to meet the strict requirements of the aerospace industry.
Do you support lightweight composite hinge designs?
Yes. We machine hybrid metal-polymer hinges using PEEK and aluminum for reduced weight while maintaining structural integrity.
How long does it take to produce and qualify a new hinge design?
Typical lead times range from 4 to 7 days, depending on the complexity and testing requirements. Rapid prototyping and expedited certification are also available for urgent projects.
