ATTENTION: ASSISTANT REGIONAL ADMINISTRATORS FOR TECHNICAL SUPPORT FROM: THOMAS J. SHEPICH Director Directorate of Technical Support SUBJECT: Process Modification - Thermoset Resin Technology Replacement for Lead in Drop Hammer Punches
Akemi Plastics in Eaton Rapids, Michigan brought to our attention a system which uses a thermoset plastic resin as a replacement for lead in drop hammers. Other lead containing metal alloys used in drop hammer applications, such as kirksite, can also be eliminated. This system is according to the company making an impact in the aircraft/aerospace industry by providing companies with an alternative to lead.
We have not performed any study on the technology to identify potential safety or health hazards. However, according to Akemi Plastics this technology reduces the dependency on lead smelting needed to manufacture drop hammer punches. When this technology is used it eliminates workers' exposure to lead.
