GRANDIND® shares a practical application case of its CNC Precision Nylon Support Pillar (GI-CNC-PT-003), a high-precision supporting component designed to solve common insulation and stability pain points for electronic and automation equipment manufacturers.

Our client, a professional electronic equipment manufacturer, faced critical issues with their original metal support pillars: poor electrical insulation led to short-circuit risks in PCB board assemblies, while metal’s rigidity caused vibration damage to sensitive components, and heavy weight increased equipment load. These problems affected product safety and service life, prompting them to seek a custom non-metallic solution.

Strictly following the client’s 2D/3D drawings, GRANDIND® selected high-performance engineering nylon (PA6) for the GI-CNC-PT-003 support pillar—chosen for its excellent electrical insulation, lightweight, wear resistance and damping properties, which perfectly address the client’s pain points. The pillar was produced via high-precision CNC turning, ensuring tight tolerances for outer diameter, inner diameter and length, with strict concentricity control to avoid misalignment during assembly.

The nylon material’s inherent insulation performance effectively isolates electrical contact, eliminating short-circuit risks between PCB boards and metal components—a key requirement for electronic equipment safety. Its damping properties also reduce vibration and noise during equipment operation, protecting sensitive electronic parts from damage, while the lightweight design reduces overall equipment weight without compromising support strength.

After delivery, the client reported significant improvements: short-circuit risks were completely eliminated, assembly stability increased by 90%, and equipment weight was reduced by 40% compared to using metal pillars. The nylon support pillars also showed excellent wear resistance and corrosion resistance, adapting well to industrial working environments and extending the service life of the client’s products by 60%.

“GRANDIND®’s nylon support pillar solved our core safety and stability issues,” noted the client’s technical director. “The precise CNC machining ensures perfect fit, and the nylon material’s insulation and damping performance exceed our expectations—ideal for our electronic equipment mass production.”

GRANDIND® specializes in custom CNC machined plastic components, supporting small-batch prototypes and large-volume production of the GI-CNC-PT-003 nylon support pillar. The product is widely used in electronic enclosures, instrumentation, automation equipment and precision assemblies, delivering reliable support, insulation and spacing solutions.
