3M Celebrates a Major Milestone with Friction Shims
The compact yet powerful 3M™ Friction Shims have made a significant impact in various demanding sectors, including automotive, wind energy, and aerospace. Recently, 3M announced a remarkable achievement: the production and sale of over 300 million Friction Shims globally, highlighting their success in the advanced materials division.
Innovative Design and Performance
Engineered to boost performance in bolted connections, 3M™ Friction Shims are thin steel components that enhance maximum load and peak torque without requiring extra fasteners or expensive redesigns. Amy McLaughlin, president of 3M's Advanced Materials Division, stated that this milestone showcases their dedication to delivering effective solutions for their customers' design challenges.
Understanding How Friction Shims Operate
Friction Shims significantly enhance the friction coefficients in both torsional and static joints, making them particularly beneficial in the automotive industry. Each shim is crafted from nickel-coated steel and features partially embedded diamond particles that provide exceptional durability. When pressure is applied between two surfaces, these diamonds effectively grip each surface, creating a microform fit that greatly improves joint stability.
Advantages of 3M Friction Shims
There are numerous benefits to using 3M™ Friction Shims, especially as electric vehicles become more prevalent. With the added weight from heavy lithium-ion battery packs and increased torque, traditional bolted connections may struggle. 3M’s innovative solution achieves static friction coefficients that can be five times higher than conventional methods, ensuring that critical joints remain secure under greater stress.
Wide-Ranging Applications Across Industries
3M Friction Shims find extensive applications, particularly in automotive design. They enable lightweight yet strong engineering across various joints, including:
- Shear joints in automotive chassis
- Torsional joints
- Flange joints
- Bolted connections
- Fastener systems
Thanks to their versatile design, these shims can be used as drop-in solutions to stabilize joints in different manufacturing processes, further improving operational efficiency.
Applications in Engineering
Engineers can utilize 3M Friction Shims in several ways, such as:
- Securing critical joints: Enhancing stability in battery mounts and suspensions across various vehicle types.
- Optimizing design: Allowing for fewer and smaller fasteners while still managing higher loads.
- Pursuing lightweight designs: Achieving significant performance without adding weight, which is vital in electric vehicle designs.
- Managing NVH (Noise, Vibration, Harshness): Reducing micromovements in bolted joints to enhance the overall passenger experience.
