Lead-Free Solder Recycle Machine

Lead-Free solder recycling system efficiently separates solder in the solder dross, which tends to increase, from oxides. Specially-processed sesame (E-Sesame) is mixed with dross, and after heating and agitation solder is separated from oxides. Separated solder is put in a simple mold to make bar solder for reuse. About 90% of solder can be recycled.
