Cleanroom Injection Molding Services

Fecision runs Class 1000 and Class 10,000 cleanroom injection molding, used primarily for precision LSR sealing components and high-end electronics parts, with medical-grade production available as a secondary capability when a project specifically requires it. Cleanroom class, validation requirements, and material choice all get scoped together during DFM.

Cleanroom Injection Molding Capabilities

Cleanroom injection molding runs the molding, and in some cases the packaging, inside a controlled environment that limits airborne particles — protecting parts that can't tolerate contamination from dust, fibers, or other debris during production.

Validation and Quality Assurance

Cleanroom production runs on more than just a controlled room — it depends on documented validation and traceability that a buyer can audit.

IQ, OQ, and PQ validation — installation qualification, operational qualification, and performance qualification — confirm that equipment is installed correctly, runs within its specified parameters, and consistently produces parts that meet spec, in that order. Batch records tie finished parts back to the specific material lot and process parameters used to produce them, which is what makes a contamination issue traceable to its source rather than just a symptom to fix after the fact.

Cleanroom class itself isn't picked freely — under frameworks like ISO 13485, the class selected for a given part needs to be justified with a documented risk assessment, not chosen because a higher class sounds safer.

Designing a Part for Cleanroom Molding

A few design habits carry over from general cleanroom manufacturing best practice, whether the end application is medical or high-end electronics:

Where biocompatibility applies, material selection needs to account for it early — patient or user contact type and duration affect which material grades are appropriate, and switching materials late in development can mean re-validating from scratch.

Design for clean surfaces: eliminate dead spaces and crevices where particles or residue can collect, and favor smooth, easily cleanable geometry over features that are hard to inspect or wipe down.

Confirm material compatibility with the part's intended sterilization method (if any) during design, not after — not every resin holds up the same way to gamma, EtO, or autoclave exposure.

Plan for regulatory documentation from the start if the part is headed toward a regulated application — design history, risk management records, and traceability data are much easier to assemble when they're built in from the beginning rather than reconstructed later.

Where Cleanroom Molding at Fecision Is Used

Class 1000 cleanroom capacity is used most for LSR sealing components and precision electronics parts that need protection from particle contamination during molding — waterproof connectors and similar precision assemblies fall in this category.

Class 10,000 supports broader high-end electronics and food-grade production where the contamination sensitivity is real but less stringent.

Certifications and Facility Verification

Cleanroom claims are easiest to trust with documentation behind them.

ISO 13485:2016 certification, supporting Fecision’s medical-adjacent cleanroom molding capability.

GMP Compliant, covering the Class 1000/10,000 production environment.

10,000-class workshop inspection certificate, verifying the cleanroom environment meets its stated classification.

Frequently Asked Questions

What's the difference between Class 1000 and Class 10,000 cleanrooms?

The classification refers to the maximum number of airborne particles allowed per cubic foot — Class 1000 is roughly ten times cleaner than Class 10,000. Class 1000 is used for the most contamination-sensitive parts, like medical-grade LSR and precision electronics; Class 10,000 suits high-end electronics and food-grade production with somewhat more tolerance for particle exposure.

How does Fecision's cleanroom classification compare to the ISO 14644 standard?

Fecision's Class 1000 and Class 10,000 designations follow the older FS209E system, which corresponds roughly to ISO Class 6 and ISO Class 7 under the more commonly referenced ISO 14644 standard used internationally today.

Can cleanroom-molded parts be packaged in the same controlled environment?

Packaging within the same controlled environment is standard practice for cleanroom molding generally, since it prevents recontamination between molding and shipment. Specific packaging scope gets confirmed per project.
