GUEST COLUMN recycled material. Most RE waste is produced from the swarf, which results from machining alloy blocks or magnets.With present technology, the cost of recycling swarf and reducing it to its constituent elements is more than double the cost of producing magnets from fresh REM. Moreover, the heavy use of acids in the recycling process creates a whole new environmental cost in the disposal of the toxic by-products. • Re-assemble magnetic components with non-magnetic components to create a value-added assembly. Figure 2 illustrates examples of typical value-added magnetic assemblies. CWIEME Chicago 2012 U.S.A’s Largest Exhibition Electrical Insulation Materials for Figure 2. Masked in the depths of the REM crisis, lurk other less sinister but growing economic issues for the REM marketplace: • Labor costs in China have more than doubled. The average factory worker who was earning $125/mo in 2010 is now earning $235 to $300/mo. • Energy costs in China continue to escalate. This reflects itself in the cost of power and rolling brownouts across industrial sectors throughout China, particularly during Summer-time. • Transportation costs in China increase with the cost of packaging materials, fuel and labor, year on year. • REM taxes and duties for China-made REM products are in discussion with the Chinese government seeking more ways to contain the Chinese REM black market and control the flow of REM products out of China, without resorting to the usage of highlycriticized quotas. Electromagnetic Coil, Electric Motor China has been steadily moving downstream in products such as electronics, speakers andmotors. This trend is no less applicable to magnetic assemblies. Needing to create 20 million new jobs over the next decade, all government economic policies favor downstream industries over specialist industries such as the REM industry. The synergies of processing REM products downstream into a complete assembly mitigate growing costs in labor, energy and transportation. By consolidating the customer’s supply base, components are handled by a single factory instead of many. The closeness of such a strategic relationship between customer and supplier fosters loyalty and product familiarity. Ultimately, this guarantees overall quality and consistency of the assembled product. Conclusions Redesign is an all-or-nothing proposition with the risk of throwing the baby out with the bath water. It is also a lengthy process, often taking years for results. By the time the pendulum swings back the other way and REM prices normalize within an economical and stable range, what does one do with the now over-priced re-design? Recycling RE waste still has some ways to go economically, even as a host of new companies enter the REM marketplace to tackle this issue. This does not provide short-term relief in REM pricing or availability. The most pragmatic, short-term solution may well be striking a balance between reduce and re-assemble. Designing for performance one really needs, improving yield rates through judicious design and combining value-added assembly services of a trusted manufacturer may provide the optimum path for most companies.
