Validated tooling, controlled process, repeatable batches. We mold unfilled and filled PEEK into precision components for valve & pump systems, electrical insulation, semiconductor equipment and metal-replacement applications.
PEEK injection molding pays off when the design is validated, the geometry is complex, and you need repeatable batches in volume. Once tooling is locked, unit cost drops and part-to-part consistency reaches a level CNC simply cannot match.
But PEEK is not a commodity polymer. Mold steel selection, gate design, melt temperature (around 400 °C) and shrinkage allowances all matter — and getting any of them wrong shows up as warpage, short shots or premature mold wear. We engineer the tool and the process specifically for PEEK, not a generic plastic part.
From DFM and tooling through to validated production — managed by one engineering team, not handed off between vendors.
Design-for-manufacture review before tooling. We flag wall thickness, gating, draft, shrinkage and mold release issues while changes are still cheap.
Single-cavity prototype tools through multi-cavity production tools. PEEK-grade steels and surface treatments for long tool life under abrasive filled grades.
Locked process parameters per part, batch traceability, and consistent quality from first run to reorder. Suited for unfilled and filled PEEK at production volume.
Standard ranges we deliver routinely. Tighter values are achievable — discuss your part with us.
| Specification | Standard Capability | Notes |
|---|---|---|
| Dimensional tolerance | ±0.05 mm | ±0.03 mm achievable on critical features |
| Wall thickness | 0.8 – 6 mm | Below 0.8 mm requires DFM review |
| Part weight range | 0.05 – 500 g | Multi-cavity for small precision parts |
| Melt temperature | 360 – 400 °C | Grade-specific, fully process-controlled |
| Mold steel | P20 / 718H / S136 / NAK80 | Hardened steels for filled PEEK |
| Cavity count | 1 – 16+ | Sized to annual volume |
| Tooling lead time | 4 – 8 weeks | Through T1 mold trial & sample |
| Production lead time | 2 – 4 weeks | Per batch after process lock |
Not every project needs a full production tool on day one. We match tooling investment to where the project actually is.
Single-cavity, soft-steel tooling for design validation and pre-production trial runs before committing to full production tooling.
Mid-life tooling for projects ramping into production — proves out the part at moderate volume before committing to a full multi-cavity tool.
Hardened multi-cavity tools designed for the long haul. Built for filled PEEK abrasion, with hot runners and balanced cavity layouts.
We help you select the right injection-grade resin based on flow behavior, mechanical load and service environment.
Standard injection-grade resin for general engineering parts with good toughness and clean appearance.
Higher rigidity and dimensional stability for parts under sustained load. Standard for structural moldings.
Higher strength, better wear resistance and partial conductivity. Common for metal-replacement parts.
PTFE / graphite blends for low-friction sliding contact and long service life in moving assemblies.
Static-dissipative PEEK for semiconductor and electronics handling components.
Selected to meet certifications, FDA contact, low outgassing or food-contact requirements.
Application-driven examples — every project is built to your drawing.
High-volume sliding and contact parts in carbon- or PTFE-modified PEEK.
Complex molded fluid-system parts replacing machined metal components.
Small-feature high-temperature insulators with consistent batch quality.
High-temperature connector housings and internal precision moldings.
Lightweight PEEK alternatives to machined steel and aluminum components.
Cleanroom-friendly carriers, holders and process fixtures.
Molded gears, bushings and rotating parts in glass- or carbon-filled PEEK.
Micro-feature parts produced in multi-cavity tooling at high volume.
STEP review for moldability, draft, gating and grade fit.
Mold design quote, cavity count, lead time and unit price.
Steel selection, machining, polishing, assembly per spec.
First mold trial with sample report for your approval.
Process locked, dimensional report, material certificate.
Batch runs with traceability, then ship worldwide.
PEEK molding rewards process discipline. Here's where we apply it.
We review every design before quoting a mold. Catching draft, wall thickness or gate location issues before steel is cut saves real money.
Melt temperature, mold temperature, hold pressure and cooling time are all PEEK-tuned — not borrowed from commodity polymer process sheets.
Filled PEEK wears mold steel fast if you use the wrong grade. We spec hardened mold steels and surface treatments designed to last under filled-grade production.
After T1 approval, parameters are locked per part. Reorders reproduce the part you signed off on — not a "close enough" version.
Generally 5,000+ pieces per year makes sense. Below that, CNC machining is usually more cost-effective. We're happy to compare both options for your part.
You do. Once you pay for the tooling, the mold is yours — held at our facility for production runs, but transferable on request.
Yes — glass-filled, carbon-filled, wear-modified and conductive grades are routine. Filled grades are more abrasive on tooling, which we account for in mold design.
4 – 8 weeks from PO depending on part complexity, cavity count and tool steel. We send a project schedule with the mold quote.
Yes. Minor revisions are quoted separately based on the change. We don't push back on revisions — we'd rather get the part right than rush production.
Yes. Material certificates traceable to the resin batch, plus dimensional inspection records, come with every production shipment.
DFM review, mold design, lead time and unit pricing — all included with every injection molding quote.
