1.Product Introduction

Dongguan TongToo Aluminum Products Co., Ltd. focuses on the die extrusion production and CNC precision machining of aviation-grade aluminum alloy frame structural profiles. It uses 7075-T6, 2024-T3 and other aviation aluminum materials. Through the independently developed mold design system and CNC machining center, it provides a full-process solution from profile extrusion → heat treatment → finishing → surface treatment. The products are widely used in key parts such as aircraft fuselage frames, satellite bearing structures, and drone skeletons, helping to make aviation equipment lightweight and high-performance.

7. FAQ

Q: What is the minimum wall thickness of profile extrusion?

A: The wall thickness of conventional aviation profiles is 1.5-8mm, and the ultra-thin profile can be 0.8mm (requires reinforcement rib design).

Q: Can conductive oxidation or insulation treatment be provided?

A: Support:

Conductive oxidation (surface resistance ≤ 0.1Ω/sq)

Anodized insulation (voltage resistance ≥ 500V)

Q: How to calculate the cost of profile mold opening?

A: The quotation is graded according to the complexity of the section and the life of the mold. Please consult customer service for the specific cost.
