Precision manufacturing in ISO‑controlled environments for medical, electronics and high‑reliability products
W&S Plastics operates cleanroom facilities across Australia and Malaysia to produce and assemble components that demand stringent contamination control. In Sydney we run an ISO Class 7 cleanroom with a dedicated ISO 7 clean moulding cell and bio‑controlled environment; in Johor, the entire production area is ISO Class 8, with assembly lines operating at ISO Class 7. These spaces support regulated medical devices, sensitive electronics and other precision assemblies.

Cleanroom Facilities Overview
Sydney, Australia
- ISO Class 7 cleanroom and ISO 7 clean moulding cell for sensitive moulding and assembly operations.
- Bio‑controlled environment to safeguard product integrity from moulding through to packaging.
Johor, Malaysia
- Entire production area certified to ISO Class 8, ideal for high‑volume precision components.
-
ISO Class 7 assembly line with heightened particle controls for contamination‑critical builds.
What We Do Inside Our Cleanrooms
We deliver end‑to‑end manufacturing and assembly under clean‑controlled conditions to reduce bioburden risk, protect cosmetic surfaces, and ensure consistent performance.
- Cleanroom injection moulding (ISO 7/8), including multi‑shot and insert/overmoulding, integrated with post‑moulding steps as required.
- Cleanroom assembly—manual, semi‑automated and automated lines sized for cells or full product builds.
- Clean‑compatible finishing such as pad/screen printing, laser marking, ultrasonic welding and heat staking (applied in clean or controlled environments as appropriate to the product).
- In‑process and end‑of‑line testing including leak and airflow tests, electrical continuity, force/flatness checks, and rub & peel.

Environmental Control & Monitoring
Our cleanrooms are maintained with defined particulate limits, environmental controls and documented monitoring:
- Routine particle count monitoring—monthly in the ISO 8 production area and weekly on the ISO 7 assembly line in Malaysia—supports ongoing compliance.
- Climate‑controlled cleanroom production areas maintain stable temperature and humidity profiles aligned with process needs
Quality, Validation & Regulatory Alignment
Cleanroom manufacturing is integrated with our certified Quality Management Systems:
- ISO 13485:2016 and ISO 9001:2015 at both sites; ISO 14001:2015 in Johor.
- Robust design and process controls including DFMEA, PFMEA and Process Control Plans for risk‑based governance.
- Tool and process validation (IQ/OQ/PQ) with documented protocols, capability analysis and frozen processes that carry into production.
Materials & Sustainability in Clean Environments
Clean Logistics, Traceability & Dispatch
Cleanroom builds are backed by disciplined warehousing and ERP controls:
- Separated raw‑material and finished‑goods warehouses in Sydney with flow‑through racking for FIFO and best‑practice material flow.
- PRONTO Xi ERP batch control from receiving to dispatch; certificates of conformance captured and FIFO enforced. With basic label data we can trace back to machine, process, material and batch.
- Retail‑ready storage and distribution when required—ship to multiple delivery points with confidence.
Applications & Example Use Cases
Our clean environments support a broad range of critical applications:
- Medical: precision ventilator sub‑assemblies, diagnostics/IVF consumables, sleep‑apnoea components.
- Electronics & precision assemblies requiring tight contamination control and robust cosmetic quality.
Why Choose W&S Cleanrooms?
