DAOLER® Friction Shims: Precisely Matching Ideal Specifications for Every Vehicle, Empowering the Future of New Energy
DAOLER® Friction Shims cover a full range of sizes and performance grades, meeting the demands of new energy vehicles (NEVs) in terms of high torque, high-frequency vibration, and complex electrical environments. We provide professional selection services and rigorous environmental validation.
In automotive manufacturing and after-sales service, friction shims—though small in size—play critical roles in preventing loosening, damping vibration, conducting electricity, and resisting wear. With the rapid advancement of electric vehicles (EVs), more stringent requirements have emerged, including exposure to higher torque, increased vibration frequencies, and more complex electrical conditions. Faced with diverse application scenarios, how can engineers quickly and accurately select the most suitable shim specifications? DAOLER® offers a one-stop solution.
Wide Range of Sizes and Grades for All Application Scenarios
DAOLER® Friction Shims feature an industry-leading product matrix—from micro-sized precision electronic components to heavy-duty chassis structures, and from small-diameter standard parts to large-dimension special applications. We offer dozens of standard sizes and multiple performance grades. Whether you require high-temperature resistance, a specific coefficient of friction, or conductive/insulating properties, you will find the right model in the DAOLER® product portfolio.
All products undergo rigorous load testing, salt-spray corrosion testing, and thermal cycle validation, ensuring stable clamping force and consistent contact resistance even under extreme temperatures ranging from -40°C to 200°C.
One-on-One Engineering Support for Hassle-Free Selection
Faced with complex specification parameters, engineers often spend significant time on comparison and validation. DAOLER® not only provides products but also delivers "engineer-to-engineer" professional services. Our application technology team, with an average of over 10 years of experience in the automotive industry, can:
----Quickly recommend the optimal size and grade combination based on your assembly torque, substrate material, vibration frequency, and other operating data.
----Provide customized friction coefficient solutions for special applications such as battery packs, electric drive systems, and high-voltage connectors in NEVs.
----Assist with DV/PV (Design Verification/Production Validation) and provide selection reports, helping to shorten development cycles.
Focus on NEV Applications: Solving Three Core Challenges
Driven by the trend toward electrification, DAOLER® Friction Shims have been successfully adopted by major automakers and "Triple-E" (Electric Drive, Battery, Electronic Control) suppliers. Typical applications include:
----Battery Pack Module Fixation: Prevents connection loosening due to vibration via a highly stable coefficient of friction while controlling contact resistance to enhance safety.
----Electronic Control Unit (ECU) Grounding: Provides low-contact-resistance grade shims to ensure electrical continuity in high-voltage circuits.
----Drive Motor Housing Assembly: Employs high-temperature resistant, anti-creep grade shims designed for long-term thermal load operation of electric motors.
For each EV application, our engineers holistically evaluate conductivity requirements, thermal management demands, and assembly process constraints to deliver selection recommendations that balance performance and cost-effectiveness.
