UAV Landing Gear Injection Molding Case | PA6 GF Precision Mold by Huashuo

Project Background

With the rapid growth of the low-altitude economy, a startup specializing in industrial UAVs approached Huashuo for support on a new drone landing gear component. The part required the use of PA6 reinforced with 45% glass fiber (PA6+45% GF) to achieve an optimal balance between lightweight performance and high structural strength, ensuring stability under repeated takeoff and landing conditions.

Challenges

The component features a highly complex geometry with dense reinforcing ribs, variable wall thickness, and multiple high-precision assembly interfaces. These characteristics created several technical challenges:

• Complex parting line design due to undercuts and multi-directional structures
• High risk of warpage and deformation caused by glass fiber reinforcement
• Tight dimensional tolerances required for assembly accuracy
• Previous suppliers struggled with high tooling costs, long lead times, and limited feasibility in design optimization

Huashuo Solution

Huashuo provided a full-process engineering solution, from design optimization to mass production:

• Conducted mold flow analysis (MFA) to optimize material flow, gate location, and cooling system
• Redesigned the parting line and gating system to reduce mold complexity while maintaining structural integrity
• Applied multi-slide mold structure to handle complex undercuts and ensure precise demolding
• Optimized rib layout and wall thickness to minimize warpage and improve strength distribution
• Implemented strict process control during injection molding to ensure repeatability and dimensional stability

This approach not only reduced tooling difficulty and cost but also ensured high assembly precision and long-term production reliability.
