Industrial Factory Audit: Why Secondary Post-Curing is Non-Negotiable for Silicone LED Masks

For global beauty brands managing OEM/ODM sourcing, standard factory audits often overlook the silicone curing phase. Many consumer-grade factories use one-step injection molding and ship the product immediately.

However, medical-grade compliance requires a strict 4-hour secondary post-baking (post-curing) process in industrial ovens at 200°C. This chemical stabilization phase drives off all remaining volatile organic compounds (VOCs) and siloxane residues, ensuring zero skin irritation and zero chemical smell under LED heat. At Skifir’s manufacturing facility, every batch of flexible silicone phototherapy hardware underwent this double-curing standard before entering assembly.
