Cleanrooms are used in certain sectors of the injection molding industry, where airborne particles may cause an adverse effect to the molding process or end product. Industry’s using cleanroom technology include medical device, pharmaceutical, life sciences food packaging and military.


Cleanrooms vary in size, design and classification but the common function is to remove airborne contamination from a contained area. Often cleanrooms are designed to control and maintain environmental conditions such as temperature, humidity and pressure. Consistent environmental conditions are also advantageous in maintaining a stable molding process. High-efficiency particulate air (HEPA) filters are used to remove airborne particles as small as 0.3 microns, for increased levels of cleanliness, Ultra Low Particulate Air (ULPA) filters are required.

Manufacturers using clean rooms usually follow Good Manufacturing Practice (GMP), which includes training, test records calibration. Persons entering a cleanroom are usually required to wear special clothing, to reduce the spread of contamination. Cleanroom garments often include hair nets, beard covers, lab coats, shoe covers, face masks, and goggles.
