Precision ESD Plastic Machining

ESD-Safe Plastic CNC Machining

Protect sensitive electronics and reduce static-related failures with ESD-safe plastic components precisely machined to your drawings. PlasticCNCPro specializes in CNC machining of engineering plastics and high-performance polymers—including static-dissipative and conductive grades—for prototypes, low-volume production, and repeat manufacturing.

Understanding ESD Classifications

What "ESD-Safe" Means

Antistatic

Minimizes charge generation. Often surface-treated or inherently low-charging plastics; not a defined resistivity class.

Static-Dissipative

Surface resistivity typically 1×10⁶ to 1×10⁹ Ω/sq. Safely bleeds charge at a controlled rate.

Conductive

Surface resistivity typically <1×10⁵ Ω/sq. Rapid charge equalization and grounding.

Actual properties depend on the specific grade, humidity, temperature, and cleanliness. We can machine to your target resistivity class and arrange testing per ASTM D257 or ANSI/ESD S11.11 on request.

Material Expertise

ESD-Safe Materials We Machine

We help you select grades balancing ESD performance, mechanical strength, dimensional stability, temperature resistance, chemical resistance, and cost.

Typical ESD grades are black or dark due to carbon loading; some dissipative grades are gray or translucent.

Capabilities Overview

CNC Capabilities for ESD Components

  • CNC milling, turning, drilling, tapping, threading, slotting, pocketing, contouring, counterbores, countersinks, and complex 2D/3D features.
  • Size range: from small precision inserts to larger panels, covers, guides, and pallets.
  • Tolerances: ±0.05 mm typical; ±0.01–0.02 mm achievable on select dimensions with stable materials (e.g., PEEK, POM).
  • Surface finish: as-machined, fine finishing, polishing (material-dependent). Note: filled ESD grades have a more matte finish.
  • Deburring, edge conditioning, press-fit/heat/ultrasonic inserts, laser/ink marking, and ESD-safe handling & packaging.

Design Guidance

Design Tips for ESD-Safe Machined Plastics

  • Define target resistivity and test standard (ASTM D257, ANSI/ESD S11.11).
  • Use generous corner radii, avoid abrupt section changes to reduce stress risers in filled materials.
  • Keep wall thickness uniform; very thin walls in filled grades can be brittle.
  • Specify metal inserts or thread bushings for repeated assembly.
  • Call out grounding points, threaded holes, or embedded hardware for reliable ESD paths.

We provide DFM feedback before production to balance ESD performance, mechanical reliability, and manufacturability.
