Advanced Cleanroom Facility in the USA Built for Box Build Medical Device Assembly
Our cleanroom contract manufacturing solutions support a broad range of device types, from packaging and subassembly to final build with our ISO Class 7 and ISO Class 8 validation. Class 8 environments are ideal for upstream processes like component preparation and packaging, while Class 7 zones are designated for sterile assembly and high-risk medical builds.
Our cleanroom infrastructure is engineered for particulate, microbial, and environmental control at every level. We maintain a tightly regulated environment to maintain product consistency, compliance, and performance.
Whether preparing for a regulatory filing, third-party audit, or FDA inspection, our cleanroom contract manufacturing records are always ready for review.

- → PCB Box Build Assembly Services: Facilitating design and assembly of complex parts of medical devices for optimal functionality.
- → Vacuum Forming: Form rigid films into precise shapes for trays, enclosures, and sterile packaging applications.
- → High-Speed Die Cutting: Rapidly cuts complex geometries with tight tolerances for foams, films, and layered materials.
- → Cleanroom Laundering: Removes particulates and residues from materials to meet Class 7 and Class 8 cleanroom standards.
- → Surgical Instruments and Tools: Handheld or powered devices used in operating rooms, designed for durability, sterility, and precision during invasive procedures.
- → Diagnostic and Monitoring Devices: Non-invasive and minimally invasive systems such as patient monitors, test kits, and point-of-care diagnostics requiring contamination-free builds.
- → Implantable Devices (Orthopedic, Cardiovascular, Neurological): Permanent or semi-permanent implants, including stents, joint replacements, and neurostimulators, requiring sterile assembly and absolute quality control.
- → Drug Delivery Systems (e.g., inhalers, injectors): Single and multi-use devices like fluid warming systems, auto-injectors, inhalers, and infusion systems that must maintain drug stability and meet strict sterility requirements.
- → Custom-engineered packaging materials and sealing methods that preserve sterility from cleanroom to point of use.
- → Fully traceable labeling solutions to meet UDI and global compliance standards.
- → Collaborative Engineering Support: Early-stage design input and PCB reverse engineering services to reduce risk and optimize for cleanroom assembly from the start.
- → Value-Added Cleanroom Services: Comprehensive in-house offerings such as kitting, functional testing, inspection, and final packaging, all performed within controlled environments.

Quality Assurance and Process Control in Cleanroom Contract Manufacturing
Biomedical device manufacturing hinges on contamination-free surroundings to safeguard product integrity and function. While contamination is a quality issue, it can pose a serious risk to patient safety and compromise your goodwill. Thus, cleanroom contract manufacturing is the only path forward for medical device OEMs. At MFG One, our advanced cleanroom facility based in the USA eliminates risk with high-efficiency airflow systems, strict gowning protocols, and continuous monitoring.
While speeding up the time-to-market of your medical device, we reinforce regulatory compliance and uphold product integrity.
- Environmental Monitoring: Our microbiological team routinely monitors temperatures and particulate levels for keeping contamination under control.
- Process Validation: Our assembly processes are validated using IQ/OQ/PQ protocols. We apply statistical process control (SPC) to maintain repeatability and detect deviations early.
- Traceability and Documentation: Every material, lot, and process step is traceable from intake to shipment. Detailed documentation supports FDA audits and global regulatory submissions.
- Risk Management: We proactively assess and mitigate risks specific to cleanroom manufacturing with CAPA protocols for swift correction of deviations and long-term process integrity.
