Unimagnet has been manufacture micro motor magnetic strips for six years. Based constantly investment in research and development, our gifted team has solved many stubborn problems in the micro motor strips field. Such as high temperature resistant can reach 172 Celsius degrees, talcum powder separate problem etc.
Unimagnet manufacture micro motor magnetic stirps by mix ferrite powder, polyethylene, plasticiser and stabilizing agent by special proportion, and adopt continuous produce and multilayer roller compaction technics. The finial products of micro motor magnetic strips with stable magnetic performance, precise shape size and high temperature resistant ability.
