Cleanroom Manufacturing & Assembly

Calvin Koh, marketing manager, Vincent Medical Manufacturing Co., Kowloon, Hong Kong.

When selecting a cleanroom manufacturer, begin with the basics. First, is the effective area of the cleanroom large enough to manufacture your product, now and in the future? Second, how much of the cleanroom’s space is currently allocated to other projects? Is there enough space available to manufacture your product on the proper scale? Third, does the facility have the necessary certifications to accommodate the FDA class of your product?

Once the OEM has confirmed the suitability of the facility, the validation and quality control processes must be evaluated. The cleanroom should have an available validation report generated during construction, and revalidation reports should be prepared periodically. In addition, the facility should have full test records on file from a recognized third-party laboratory. The cleanroom should have an internal quality control department capable of strictly monitoring the manufacturing environment’s cleanliness and sterility. An in-house microbiological laboratory for quality control can provide greater efficiency, but check that the laboratory operators have been certified by local government.

Finally, take into account the specific requirements of your product. For example, if it’s a plastic disposable medical product, does the cleanroom offer injection molding? Blow molding? Assembly? Packaging? What kinds of packaging does it provide? The largest, most pristine cleanroom won’t be helpful to you if it doesn’t have the capabilities your product requires.
