DAOLER® — Specializing in the R&D and Manufacturing of High-Reliability Friction Shims
In the precision transmission systems of industrial manufacturing, friction shims serve as indispensable core foundational components, whose performance directly determines equipment transmission accuracy, operational stability, and service life. This seemingly simple "invisible guardian" effectively addresses industry pain points such as slippage, wear, and preload decay under vibratory conditions, fortifying safety barriers across industrial robotics, high-end equipment, and precision transmission applications. DAOLER Diamond Friction Shims.
Technical Breakthrough: Redefining Performance Envelopes
DAOLER® has long been dedicated to the friction shim sector, consistently focusing on high-reliability core requirements through specialized R&D and rigorous manufacturing. The fundamental value of friction shims lies in the precise regulation of friction coefficients and optimization of interfacial architectures to achieve the objectives of "efficient force transmission, reliable locking, and superior wear resistance"—a feat demanding deep integration of materials science, surface engineering, and precision manufacturing.
Conventional friction shims commonly suffer from unstable friction coefficients, premature degradation at elevated temperatures, and inadequate wear resistance. These deficiencies are particularly pronounced in high-frequency vibration and heavy-load conditions typical of industrial robot joints, harmonic reducers, and servo drivetrains, often resulting in increased backlash, diminished positioning accuracy, and elevated maintenance frequency.
Innovative Technological Framework
DAOLER® employs a gradient composite coating architecture, utilizing nanocomposite technology to directionally embed nanoscale silicon nitride particles into the substrate, forming diamond-like hard phases. This is complemented by a copper-nickel alloy compliant transition layer, achieving a "rigid-flexible" structural synergy. This design ensures exceptional wear resistance while buffering thermal shock stresses and preventing interfacial delamination.
The proprietary electroplated diamond process ensures uniform distribution of micron-sized diamond particles across the friction surface. Coupled with laser micro-etching technology to create controlled surface topographies, this enhances mechanical interlocking effects, stabilizing the friction coefficient across a wide pressure range of 30–400 MPa—fundamentally resolving the volatility and slippage issues inherent in traditional shims.
Stringent Material Standards
In material selection, DAOLER® adheres to uncompromising standards, meticulously choosing high-strength, high-wear-resistance, and high-temperature-resistant composite substrates, with each batch of raw materials rigorously screened to eliminate contaminants. Tailored to the specific demands of diverse application scenarios, the optimized material formulation enables stable operation across a broad temperature spectrum from –50 °C to 480 °C, delivering thermal stability exceeding that of organic-based materials by more than fivefold, with friction performance degradation below 8 % under oil-lubricated conditions. DAOLER Diamond Friction Shims.
Precision Manufacturing Processes
DAOLER® embodies the philosophy of "precision manufacturing and continuous improvement," incorporating high-precision production equipment and a comprehensive quality management system spanning the entire process. From substrate cutting and coating deposition to final forming, every manufacturing step adheres to stringent process standards. Professional instruments including micrometers with accuracy no less than 0.01 mm and constant-speed friction testers are employed to rigorously control dimensional tolerances and surface roughness.
The product line accommodates ultra-thin specifications starting from 0.1 mm, with tolerances controlled within ±0.02 mm, enabling rapid retrofitting without modifications to existing equipment architectures—ideal for compact joint designs and high-density integrated configurations.
