Industry Application Example – Drone Industry | Custom Molded Rubber Products Manufacturer Since 1981 - YUANYU

YUANYU, an ISO and RoHS-certified manufacturer since 1981, specializes in custom molded rubber products in any shape, size, and material. With a 6,250 sq.m production plant, we produce high-quality rubber grommets, seals, o-rings, and gaskets for electronics, automotive, and industrial applications. YuanYu Rubber provides the drone industry with comprehensive solutions for vibration damping, sealing, dust protection, and EMI shielding through its professional rubber and silicone molding technologies. Leveraging custom mold development and Liquid Silicone Rubber (LSR) injection molding capabilities, YuanYu helps customers build industrial-grade and professional-grade drone platforms designed for harsh operating environments.Core Structure & Vibration Damping SystemYuanYu has mature Rubber-to-Metal Bonding technology, a key process for addressing high-frequency vibration in drones.Motor Mount Dampers: Installed between the motor and the arm connection points. Metal components provide fastening strength, while anti-vibration rubber effectively absorbs high-frequency micro-vibrations from the motor, reducing interference to the airframe and gyroscope performance.Landing Gear Shock Absorbers: Installed at the ends of the landing gear. High wear-resistant NBR or PU materials are used to reduce landing impact and protect the airframe structure.Power & Protection SystemFor industrial drones used in agriculture spraying, inspection, and similar applications, YuanYu provides rubber protective components with strong dustproof and weather-resistant performance.Servo Dust Boots: Applied to VTOL tilt-rotor mechanisms and servo linkages. They effectively block dust/sand and moisture from entering precision servo mechanisms, improving operational reliability in harsh environments.ESC Water-Cooling Hoses: EPDM rubber hoses used in water-cooling heat dissipation systems offer high-temperature resistance and coolant corrosion resistance, suitable for long-duration, high-load missions of large heavy-lift drones.Avionics Sealing & Waterproof/Dustproof ProtectionFor airtightness, waterproofing, and wiring protection, YuanYu offers both standard and custom components to help customers achieve IP-rated design targets.Fuselage Waterproof Seals: Silicone or NBR O-rings, waterproof airtight seals, and custom profiles used at housing joints and battery compartment doors, supporting IP54 / IP67 waterproof requirements.Wiring Grommets: Installed at cable exit holes in carbon-fiber plates and at folding arm locations. They prevent sharp edges from cutting power or signal cables under vibration, meeting fundamental safety design requirements for drones.Ground Control & Human–Machine InterfaceYuanYu applies conductive rubber and keypad technologies to remote controllers and ground control stations, providing both tactile performance and durability.Remote Controller Keypads: Conductive rubber keypads and P+R keypad solutions provide good tactile feedback and high durability, suitable for long-term professional operation.EMI Shielding Gaskets: Made of conductive rubber and placed under video transmission and GPS modules to effectively suppress electromagnetic interference and ensure stable video and positioning signals.Custom Development & LSR CapabilityMost critical rubber components for drones are non-standard. With strong custom mold development capability, YuanYu meets various custom geometries and high-precision requirements.Custom Molded: Custom-profile waterproof seals and special-shaped damping balls can be developed based on the customer’s airframe structure, supporting the NRE development process.LSR (Liquid Silicone Rubber) Injection Molding: Ideal for producing high-precision, high-stability damping and sealing components, especially for demanding industrial-grade and professional-grade drone applications.
