Precision Plastic Machining for Semiconductor

Plastic Parts Machined for Semiconductor Equipment

Precision CNC-machined plastic components for semiconductor tools, subsystems, and spares — from prototype lots to repeat low-volume production. PEEK, PTFE, PVDF, PCTFE, PPS, PEI, ESD-safe grades. Export-focused service from China.

What We Make for Semiconductor Equipment

Typical custom components machined to your drawings and specifications — spanning front-end and back-end processes.

Wet-Process & Chemical-Handling

Manifolds, plates, blocks, nozzles, spray wands, flow cells, drip bars, valve seats, spacers — machined in PTFE, PVDF, PFA, PP.

Wafer Handling & Automation

Grippers, end effectors, nests, aligners, guides, wear strips, standoffs — in PEEK, POM/Acetal, UHMW-PE, ESD-safe grades.

Vacuum & Process-Chamber

Insulators, bushings, shields, covers, tooling fixtures — machined in PEEK, PCTFE, PPS, PEI for low-outgassing and stability.

Electrical / ESD-Related

Antistatic/ESD-safe covers, trays, panels, carriers — in ESD-safe PEEK, POM, PC, ABS with controlled surface resistivity.

Optical & Clear Covers

Enclosures, guards, windows — machined in PC, PMMA/Acrylic, PETG with optional polishing for optical clarity.

Custom Jigs, Fixtures & Tooling

Assembly fixtures, calibration tooling, test fixtures — milled/turned in engineering plastics when molding is impractical for small batches.

Materials for Semiconductor Applications

We work across commodity, engineering, and high-performance polymers — recommending materials based on chemical resistance, cleanliness, friction, outgassing, and dimensional stability.

PTFE / PFA — exceptional chemical resistance, low friction for wet benches and aggressive chemistries
PVDF — excellent UPW and chemical compatibility, dimensional stability for fluid-handling
PEEK — high strength and temperature resistance, low outgassing for vacuum and structural parts
PCTFE — very low moisture absorption and outgassing, dimensional stability in vacuum/cryogenic
PPS / PPS GF — chemical resistance and rigidity at elevated temperatures
PEI (Ultem) / PSU / PPSU — high-temperature, hydrolysis-resistant engineering thermoplastics
PAI (Torlon) — high stiffness, wear resistance, and thermal performance for demanding wear components
POM/Acetal / UHMW-PE / Nylon — wear components and low-friction elements in non-chemical areas
PC / PMMA — transparent covers and windows with optional polishing
ESD-safe / antistatic grades — PEEK, POM, PC, ABS with controlled surface resistivity
Filled/modified grades — glass-, carbon-, or PTFE-filled for wear, stiffness, or dimensional stability

If you specify SEMI-referenced requirements or company standards for materials and cleanliness, we manufacture to your drawing and documentation needs.

CNC machined plastic parts for semiconductor equipment

Why Plastics in Semiconductor Equipment

Engineering polymers deliver critical advantages over metals in semiconductor processes — from chemical resistance to electrical insulation and weight reduction.

⚗️

Chemical Resistance

In wet-process, cleaning, and chemical distribution systems where metals corrode.

🔬

Non-Contaminating & Clean

Corrosion-free alternatives to metals with low particle generation when properly machined.
