Custom Black POM Parts, High-Precision 3C Electronics Gears & Structural Components
Header include
This product is a high-precision structural and transmission component specially designed for 3C (computer, communication, consumer electronics) products. It is made of black polyoxymethylene (POM) engineering plastic and formed through precise CNC processing. Its core value lies in combining the excellent comprehensive performance of POM materials with a stable precision of ±0.015mm, dedicated to meeting the strict requirements of modern consumer electronics for the wear resistance, low noise, lightweight and consistent appearance of internal components.
Abject of manufacture
1.Base material: Black POM (polyoxymethylene), commonly known as "acetylene". This is a crystalline polymer with a smooth surface, high hardness and good rigidity. Its natural lubricity, fatigue resistance and dimensional stability are particularly outstanding. Adding black masterbatch not only gives the parts a unified appearance, but also effectively prevents light aging and meets the aesthetic design requirements of the product.
2.Final form: Mostly small and medium-sized precision parts, commonly found in gears, transmission shafts, sliders, clamps, housing skeletons and connector sleeves, etc.
3.Core indicators: The processing tolerances of key functional dimensions are strictly controlled within ±0.015mm.
Core features and requirements
1.Balanced precision and performance (±0.015mm) : This precision grade is the "gold standard" for the internal structure of 3C products. It ensures smooth meshing of transmission components (such as gears) with extremely low noise, while guaranteeing precise assembly and reliable engagement of structural parts in a compact space, avoiding interference or loosening caused by dimensional deviations.
2.Outstanding tribological properties: The inherent low coefficient of friction and high wear resistance of POM materials make them an ideal choice for manufacturing high-speed, long-life transmission components, significantly enhancing the durability and reliability of products such as printers and smart home devices.
3.Rigidity and dimensional stability: POM can maintain excellent dimensional stability within a wide range of temperature and humidity, overcoming the drawback of common plastics that are prone to thermal expansion and contraction, ensuring consistent functionality of the product in different usage environments.
4.Aesthetic and functional coloring: The uniform black appearance avoids color differences in the internal structure, conforming to the strict internal aesthetics of modern electronic products. Meanwhile, the black material has better light-blocking properties and is suitable for peripheral components of optical sensors.
Key processes and technologies
To achieve the processing of high-quality black POM parts, it is necessary to precisely control the material properties and process details
1.Precision CNC milling and turning
(1)The core of the equipment: It relies on small precision CNC machine tools (CNC machining centers/lathes) with high rotational speed and high dynamic response to ensure surface finish and dimensional consistency during high-speed cutting.
(2)Tools and cooling: Prioritize the use of sharp single crystal diamond tools or hard alloy tools with specific geometric angles, and combine them with compressed air or oil mist cooling to effectively remove cutting heat and prevent POM materials from softening, deforming or developing burrs due to local overheating.
2.Anti-deformation and stress control strategies
(1)Scientific clamping design: Use dedicated fixtures and precisely calculate the clamping force to avoid internal stress and deformation caused by excessive clamping.
(2)Sequential processing: Adopt the strategy of "separation of rough and fine processing". Rough machining quickly removes the allowance, while finish machining uses a small cutting depth and high rotational speed to complete the final dimension refinement with the minimum cutting force, releasing and eliminating the internal stress of the material.
3.Professional post-processing and quality control
(1)Deburring and polishing: Through processes such as manual fine finishing, vibration grinding or low-temperature shot blasting, the fine burrs produced on the cutting edge are thoroughly removed to ensure that the parts feel smooth and there is no interference during assembly.
(2)Constant temperature and humidity environment testing: The final inspection is carried out in a temperature and humidity controlled metrology room. High-precision image measuring instruments or three-coordinate measuring machines (CMM) are used to conduct a full inspection of key dimensions to ensure that the tolerance zone of ±0.015mm is 100% satisfied.
Conclusion
In conclusion, this black POM component is a model of the deep integration of materials science, precision manufacturing and consumer electronics demands. With the outstanding mechanical properties and stable black color of POM material, combined with targeted micro-stress precision processing technology, it has successfully achieved large-scale stable production at a precision level of ±0.015mm, providing indispensable basic component support for 3C electronic products that pursue thinner, quieter and more durable design goals.
