We do not recommend using aerosol products in cleanroom environments. Aerosols can create overspray or product drift, which may contaminate the production area or affect other molding operations within the same room. Cleaners, release agents, rust preventives, and lubricants should always be dispensed using non-aerosol delivery systems when used in a cleanroom setting.
Hand-pump spray bottles and lint-free wipes are far better options for controlled application of cleaners, lubricants, and rust preventives. These methods allow for precise placement of the product without the risk of drift. In some cases, even cotton swabs are used to service and maintain molds within environmentally controlled areas to ensure maximum cleanliness and control.
Cleaning
Medical molding presents many of the same demanding maintenance challenges found elsewhere in the plant. The key difference is the need to introduce an effective cleaner without compromising the integrity of the cleanroom environment.
Isopropyl alcohol (IPA) is an excellent choice for cleaning molds and metal surfaces in cleanrooms and can be easily applied using a spray bottle. In higher concentrations, it provides strong cleaning power while remaining suitable for medical and food-packaging applications. For more stubborn stains or resin buildup, molders often apply isopropyl alcohol and then use a lint-free wipe to firmly clean the metal surface.
When selecting a cleaner, look for products registered under NSF Category P1, or at minimum those designated as food-approved with proper supporting certifications.
Rust prevention
Even environmentally controlled areas do not provide complete protection against oxidation and rust. Molds that sit idle—even for short periods—can begin to oxidize and corrode. For this reason, critical components should be protected at all times, including when the mold remains in the press.
Select rust preventives that are registered under NSF Category H1, or at minimum those that are food-approved and supported by the appropriate certifications.
Mold Releases
Parts that stick in the mold or refuse to release cleanly require additional attention. In medical molding, where there is virtually no margin for error, strict compliance with approved formulations and proper application methods is essential. As noted earlier, pump sprayers should be used to precisely target problem areas on the mold.
Choose release agents that are registered under NSF Category M1, or at minimum those that are food-approved with the appropriate certifications. Doing so helps ensure regulatory compliance while maintaining optimal productivity.
