Product Description

Product Overview

At Shenzhen Sunmy Hardware Co., Ltd., we specialize in transforming raw carbon fiber sheets into high-performance aviation structures. This product listing features our precision-engineered drone frame capabilities. While the showcased model features a robust Quadcopter/Deadcat geometry suitable for long-range systems, our manufacturing lines are fully equipped to produce heavy-lift Agricultural Hexacopter Frames designed to carry heavy payloads for crop spraying and seeding.

We offer a turnkey solution: from raw material selection to precision CNC cutting, chamfering, and hardware assembly. Whether you need a 7-inch FPV frame or a 15-inch+ agricultural rig, our OEM/ODM services ensure your specifications are met with aerospace-grade tolerance.


Manufacturing Process & Craftsmanship

Our manufacturing facility utilizes advanced CNC routing and machining centers specifically calibrated for composite materials.

⚙️

Precision CNC Cutting

We utilize high-speed routing to cut complex geometries with tolerances as tight as ±0.05mm, ensuring perfect alignment of arms and plates.

✨

Surface Treatment

All frames undergo edge treatment (chamfering/filleting) to prevent delamination and ensure safety during handling. We offer Matte or Glossy finishes in Twill or Plain weave.

🔩

Component Integration

We provide complete kits, including CNC-machined aluminum standoffs, high-tensile screws, and battery straps, ensuring a ready-to-assemble package.

🧱

Material Lamination

As seen in the cross-section images, our carbon fiber sheets utilize high-pressure lamination to ensure zero voids, maximizing stiffness and crash resistance.

Key Features & Advantages
  • High-Impact Resistance Engineered with high tensile strength to withstand the rigors of agricultural field use and high-speed flight maneuvers.
  • Vibration Damping The composite structure naturally absorbs high-frequency vibrations, resulting in smoother flight footage and more stable sensor data.
  • Modular Arm Design Features replaceable arms for easy maintenance and repair in the field—crucial for agricultural operations to minimize downtime.
  • Custom Layouts We accept DXF/DWG files to create frames specifically optimized for your unique payload, battery size, or motor configuration.
  • Complete Hardware Solution We don't just cut carbon; we supply the full skeleton, including customized anodized aluminum standoffs and high-grade steel fasteners.

Technical FAQ
Q1 Can Sunmy manufacture large-scale agricultural hexacopter frames not shown in the photos?
Yes. While the images show a specific long-range frame, our CNC machines accommodate large-format carbon sheets. We can manufacture heavy-lift frames (1000mm+ wheelbase) specifically for agricultural spraying and payload delivery.
Q2 What file formats do you need for a quotation?
For the most accurate quote, please provide 2D drawings in .DXF or .DWG format, or 3D models in .STEP or .IGES format.
Q3 How do you handle quality control for carbon fiber parts?
We perform a 100% visual inspection for delamination and surface defects. We also use calipers and CMM tools to ensure all hole positions and arm interlocks meet your specified tolerances.
Q4 Can you provide the aluminum hardware and screws seen in the kit photo?
Absolutely. We are a comprehensive hardware solution provider. We can source or manufacture the aluminum pillars (knurled or smooth), screws, and even custom battery straps to ship a complete kit to your customers.

Frequently Asked Questions
FAQ 1 What is the minimum order quantity (MOQ) for custom carbon fiber drone frames?
Our MOQ varies depending on the complexity and size of the frame. For standard configurations, the MOQ is typically 10 sets. For fully custom OEM/ODM designs, please contact us with your drawings for a tailored quote and MOQ discussion.
FAQ 2 What is the standard lead time for a custom carbon fiber frame order?
Standard lead time for prototype samples is 7–14 business days after drawing confirmation. Mass production orders typically require 20–30 business days depending on quantity and complexity.
FAQ 3 Can you produce frames in materials other than carbon fiber?
Yes. In addition to premium 3K carbon fiber, we can manufacture frames using fiberglass (G10/FR4) and hybrid composite laminates. Each material offers different trade-offs in weight, strength, and cost, which our engineering team can help you evaluate.
FAQ 4 Do you offer private labeling or OEM branding on the frames?
Absolutely. We support full OEM/ODM services, including custom laser engraving, silk-screen printing of logos, and custom anodized color finishes on aluminum hardware components to match your brand identity.
FAQ 5 What certifications or quality standards does Sunmy Hardware adhere to?
Our manufacturing processes follow strict ISO quality management principles. All carbon fiber materials are sourced from certified suppliers, and finished parts undergo dimensional inspection using calibrated CMM equipment and 100% visual quality checks before shipment.
FAQ 6 Can Sunmy ship a fully assembled frame kit, including all hardware?
Yes. We offer a complete turnkey kit solution that includes all carbon fiber structural plates, CNC-machined aluminum standoffs, high-tensile steel screws, and battery straps — fully packaged and ready for your assembly line or end customers.
