Antistatic and ESD-Safe Materials We Machine

We machine a wide range of engineering and high-performance polymers in antistatic, dissipative, or conductive grades.

POM / Acetal (ESD)

Standard antistatic grade for general-purpose static control.

UHMW-PE / HDPE Antistatic

Black antistatic UHMW for wear-resistant static-dissipative parts.

Nylon / PA ESD

Moisture-sensitive but strong; consider service environment.

ABS / PC ESD

Clear or opaque options depending on additive.

PET / PBT ESD

Dimensionally stable, low moisture absorption.

PPS ESD

Good chemical and thermal resistance.

PEI (Ultem) ESD

High temperature stability with ESD performance.

PPSU / PSU ESD

Medical/lab compatible, high impact resistance.

PEEK Carbon-Filled / ESD

High strength and temperature capability.

PTFE (Carbon-Filled, Conductive)

Low friction and chemical inertness with static control.

PVDF ESD

Good chemical resistance and mechanical properties.

PAI ESD

For demanding wear and high-temperature environments.

Surface Resistivity Guidance

Antistatic: ~10^9 to 10^12 Ω/sq
Static-dissipative: ~10^6 to 10^9 Ω/sq
Conductive: <10^6 Ω/sq

We recommend materials based on your heat, chemical, friction, moisture, and target resistivity requirements.

Machining Capabilities and Tolerances

Processes

CNC milling, turning, drilling, tapping, threading, slotting, complex 3D surfacing.

General Tolerances

±0.05 mm (±0.002 in) typical for plastics.

Enhanced Tolerances

±0.01–0.02 mm on select features with material, geometry, and inspection plan.

Flatness / Parallelism

0.05–0.1 mm per 100 mm typical; tighter with process controls.

Hole / Shaft Fits

H7/h7 equivalents achievable in stable materials.

Surface Finishes

Machined, matte/bead-blasted, light polishing; application-specific deburring.

Notes on Plastic Machining

We manage heat input, toolpath strategy, and fixturing to minimize warpage.
Optional annealing or conditioning for PEEK, PPS, PA to improve dimensional stability.
Coolant and cleaning procedures avoid residue that could alter surface resistivity.

Quality, Inspection, and Documentation

CMM

Dimensional Inspection

CMM, height gauges, pin gauges, thread gauges; PPAP/FAI on request.

Ω

Surface Resistivity Testing

Per ASTM D257 or IEC 61340 when specified; test conditions documented.

Mill certificates and RoHS/REACH statements when applicable.

📦

Clean Packaging

ESD-safe packaging to protect functionality and surfaces.

Design & Material Selection Tips for ESD Parts

1 Specify surface resistivity target range and test method on the drawing.
2 Balance ESD performance with mechanical strength, temperature, wear, and chemical exposure.
3 Use generous internal radii and fillets to reduce stress concentration.
4 Maintain reasonable wall thickness and avoid abrupt section changes.
5 Consider metal inserts for threads subject to repetitive assembly.
6 Include GD&T for critical datum features; define flatness/parallelism realistically.
7 Avoid cosmetic finishes that could alter ESD properties without verification.
8 Consult us early for DFM feedback to optimize cost, lead time, and stability.

Frequently Asked Questions

What is the difference between antistatic, dissipative, and conductive plastics?

Antistatic materials reduce charge buildup (typically 10^9–10^12 Ω/sq). Static-dissipative materials safely bleed off charge (10^6–10^9 Ω/sq). Conductive materials rapidly conduct charge (<10^6 Ω/sq). Choose based on your EPA and component sensitivity.

Does machining affect ESD performance?

The bulk additive/fill usually maintains ESD performance through machining. Surface alterations, residues, or contamination can impact readings. We use appropriate tooling, cleaning, and handling, and can test per ASTM D257/IEC 61340 if required.

Can you achieve tight tolerances on ESD plastics?
