High-performance PEEK positioning bracket with CNC precision milling for low-friction smart home applications

This high-performance PEEK positioning bracket is a core support component customized for smart home precision transmission mechanisms, smart door lock motor modules and automatic sensor mounting units. With an integrated L-shaped structure, it undertakes the functions of precise positioning, guidance and wear-resistant protection for micro motors and sensor modules. It perfectly adapts to the harsh requirements of long-term low-noise and high-stability operation of smart home devices. It is widely used in scenarios such as smart door locks, automatic curtains and smart home appliance transmission systems, providing low-friction and high-durability structural support for the equipment.

Core Material: PEEK (Polyether Ether Ketone), a high-performance special engineering plastic, suitable for smart home precision transmission scenarios.

Key Performance:

• Excellent mechanical strength and rigidity, tensile strength ≥90MPa, no creep deformation during long-term use
• Ultra-low friction coefficient, enabling low-noise transmission without additional lubrication, meeting the mute requirements of smart homes
• High temperature resistance, hydrolysis resistance and chemical corrosion resistance, adapting to the complex temperature and humidity environment inside home appliances without aging risk
• Excellent insulation performance, does not affect internal electronic signal transmission, fully complying with RoHS environmental protection standards

This part adopts CNC precision milling process, integrally cutting and forming from PEEK rods, avoiding shrinkage and warpage defects of injection molded parts.

• Core processes: L-shaped contour precision milling, mounting hole/threaded hole tapping, guide groove forming processing
• Auxiliary processes: high-gloss contour chamfering, deburring, surface polishing treatment, ensuring no sharp edges and stress concentration
• Full CNC programming, one-time clamping forming, ensuring the consistency of each hole coaxiality and guide groove accuracy

Machining Accuracy:

• Dimensional tolerance: ±0.02mm, strictly matching the assembly clearance of motor shaft and sensor
• Geometric tolerance: mounting hole coaxiality ≤0.03mm, guide groove parallelism ≤0.03mm
• Surface roughness: Ra≤1.6μm, smooth inner wall of the guide groove, reducing transmission friction resistance

Usage Requirements:

• Adapt to a conventional working environment of -20℃~80℃, can withstand long-term reciprocating transmission friction
• No wear, noise or loosening during long-term use, ensuring the operation stability of smart home devices
• Keep the mounting surface clean to avoid impurities entering the guide groove and affecting the smooth transmission

No additional heat treatment required. The PEEK material has completed crystallization treatment through the injection molding process, and no additional heat treatment is needed after CNC machining to avoid deformation.

Surface polishing treatment, retaining the original texture of PEEK material.

• Process advantages: improve surface finish and wear resistance, reduce friction noise, optimize appearance texture at the same time, adapt to the appearance requirements of smart home products, and can be used directly without additional coating.

Implement a full-process closed-loop quality control system, strictly complying with ISO9001 quality standards:

• Raw material incoming: material inspection to ensure that the mechanical properties and environmental protection of PEEK materials meet the standards
• Processing process: 100% geometric tolerance inspection, real-time monitoring of hole position accuracy and guide groove parallelism
• Final product inspection: appearance defect inspection, full dimensional inspection, wear resistance sampling inspection, traceable inspection report for each batch
• Pre-delivery: cleanliness inspection to ensure no debris and impurities in the guide groove and threaded holes, meeting the requirements of precision assembly
