CNC Aluminum Engine Mount Plate manufactured by Haozhifeng. Made of 6061 aluminum alloy, precision CNC machined four claw flange for large RC planes and UAV gas engines. It ensures stable mounting, accurate shaft alignment and vibration reduction. Custom sizes, hole patterns and surface finishes are available.
Our CNC Aluminum Engine Mount Plate is precision machined from high-grade aluminum alloy, designed as a critical connecting flange between gas engine and aircraft firewall for large RC planes and UAVs. The four-claw structure with multi-position mounting holes delivers stable fixation, precise axial alignment and effective vibration dispersion. Custom dimensions, hole patterns and surface finishes are available to match various engine models and customer drawings. All parts are fully inspected before shipment to guarantee consistent quality for your aviation projects.
1. Made of high-strength 6061 aluminum alloy, lightweight yet high rigidity.
2. CNC 5-axis milling ensures tight tolerance, smooth cutting surface.
3. Optimized four-spoke structure to spread engine torque and vibration.
4. Precisely drilled mounting holes for accurate positioning and easy assembly.
5. Multiple optional surface treatments: natural finish, anodizing, sandblasting.
6. Support fully customized drawing-based production for special UAV or RC engine requirements.
1. Raw Material Preparation: Select qualified aluminum alloy billets / plates.
2. CNC Programming: Generate machining codes according to customer drawings or samples.
3. CNC Milling: Rough machining then finish machining for contour and holes.
4. Deburring: Remove sharp edges and burrs manually.
5. Surface Treatment: Natural finish / sandblasting / anodizing as requested.
6. Quality Inspection: Check dimension, flatness and hole position tolerance.
7. Cleaning & Packaging: Clean workpiece, pack with anti-collision protection.
1. Strict tolerance control to maintain perfeSct coaxiality between engine and propeller.
2. Lightweight aluminum material reduces extra load on aircraft frame.
3. Anti-vibration structural design lowers stress concentration to prevent firewall cracking.
4. Haozhifeng owns complete CNC workshop, flexible for small batch prototype and mass productio
5. Fast quotation & sample service, technical team supports design optimization suggestions.
6. Stable quality control system, each batch comes with inspection report upon request.
Pain Points |
Our Solutions |
| Poor hole position accuracy leads to engine misalignment and heavy vibration | High-precision CNC machining, full dimensional inspection to guarantee hole location tolerance |
| Thin mount plate deforms under continuous engine torque | Adopt 6061 aluminum alloy and optimized four-claw structural design to improve rigidity |
| Rough burrs scratch assembly staff and affect fitting | Special deburring process after CNC machining to remove all sharp edges |
| Off-the-shelf plates cannot match special engine hole patterns | Custom machining based on your drawings, samples or parameter requirements |
| Unstable batch quality causes inconsistent assembly | Haozhifeng implements full inspection for every finished part |
1. Clean the firewall surface and the engine mount plate to remove dust and debris.
2. Align the central hole of the plate with the engine output shaft.
3. Match the pre-drilled holes on the plate with the reserved holes on aircraft firewall.
4. Insert fasteners and tighten screws evenly in diagonal sequence to avoid plate distortion.
5. Install the gas engine onto the mount plate and check the coaxiality of propeller shaft.
6. Power on and test run to check abnormal vibration, re-tighten screws if needed.
