摘要

PURPOSE: A sinker for a fish-hook or a fishing net is provided, which can be recycled by melting it at the high temperature even though deformation of a bob is generated. CONSTITUTION: A sinker(100) for a fish-hook or a fishing net is manufactured as follows. The ferric oxide of 80~90 weight% and hotmelt of 10~20 weight% are mixed in a mixer for half an hour, is heated to 80~240°C, is molded in a mold, and cooled by a cooling process of quickly cooling by water. The oxidized steel powder is 100~200 mesh. The size of sinker is relatively big.
