Between the fuselage of the unmanned aerial vehicle and the internal electronic components, high-density foam or silicone gaskets are used as a buffer layer, and the coverage area (such as around the battery compartment and flight control module) is marked to absorb flight vibrations and drop impacts.
Show the positions of the waterproof rubber strips or conductive fabrics used at the seams of the drone's casing, and explain in detail their key roles in dust prevention, water resistance and electromagnetic shielding, especially for the connection points of the motor arms of multi-rotor models.
Mark the distribution of auxiliary materials such as cable ties and silicone wire clips in the cable routing channels of the boom and around the main control board through explosion diagrams, emphasizing the optimized design for preventing cable entanglement and interference.
It is die-cut with Rogers 4701 series or Nitto P1506 foam material, with a thickness adjustable from 0.1 to 1.0mm. It is used for insulation and isolation between PCB boards and metal shells, with a breakdown voltage of over 5kV, effectively preventing the risk of short circuits.
Through die-cutting processing with tesa conductive foam tape or 3M9722 conductive tape, an electromagnetic shielding layer is formed, which can attenuate more than 30dB of interference signals and also has buffering and shock absorption functions to protect precision IC components.
It is processed by die-cutting with water-resistant WL015 waterproof PE foam or Saint-Gobain gasket, featuring an IP67-level protection design. Precise openings are made to match the interface position, preventing liquids and particles from entering.
The motor base is surrounded by 3-5mm thick PORON polyurethane foam, which is covered in an irregular shape through die-cutting technology, absorbing over 70% of high-frequency vibration energy.
Lay conductive foam at the bottom of the PCB board, which has both EMI shielding and buffering functions. The density should reach 30-50kg/m³ to balance protection and weight.
A multi-layer composite foam stacking scheme is adopted, with each layer having a hardness gradient change (from 50shore to 30shore), effectively filtering out low-frequency swaying during flight.
VHB foamed acrylic foam strips are used, die-cut and adhered along the inner wall contour of the machine body, providing dual functions of collision energy absorption and component positioning.
It is die-cut from optical-grade PET material, with a surface hardness of over 3H. The thickness can be selected from 0.05 to 0.2mm, and the light transmittance is ≥92%. It fits the curved screen or touch area of the remote control, is anti-fingerprint and does not affect the touch sensitivity.
Customized die-cut protective film for outdoor models, with UV absorbers added, blocks over 99% of UV light to prevent the shell from fading. The back adhesive is made of Nitto 5600 foam tape die-cut and punched to ensure no residual adhesive peeling.
The protective film is bonded to the shell through the die-cutting processing of 0.3mm thick acrylic foam tape, with a peel force of 5-10N/25mm. It has excellent weather resistance (-20℃ to 80℃) and does not warp even after long-term use.
As a leading provider of precision die-cutting solutions, Renhong Precision offers a wide range of products, including various types of tapes and protective films, which are widely used in consumer electronics, automotive electronics, home appliances, industrial products,semiconductor, medical devices, and new energy sectors.
