A fastener manufacturer will use a drawer oven to flash cure paint on nuts. Flash curing — heating parts at a relatively low oven temperature until they are no longer tacky but not fully cured — allows for subsequent layers of paint applications to continue building thickness.
The four drawers in the oven, which is designed and supplied by Grieve Corp., Round Lake, Ill., are perforated on the bottom and sides to allow air to circulate. Multiple drawers prevent mixing of production lots. The nuts are loaded into the drawers in aluminum mesh bags.
Because the process involves paint, the oven includes a powered forced exhauster, purge timer and the other safety equipment required by OSHA and NFPA 86 for ovens processing flammable solvents or vapors.
