Metal stamping plant first brand [Branch] Shenzhen Branch precision molds metal factory is a metal stamping and production-oriented enterprises, Main: various types of precision metal stamping dies, metal stamping shrapnel, auto metal parts, precision pull stretch, metal clips, heat sinks, mobile power shell. And to provide design and drawing services, reduction in product design changes, shorten the development cycle to address mold and part design and processing to worry about, so that products to market faster. The factory has advanced mold design software and advanced design engineers, mold manufacturing technicians, relying on professional design technology, combined with years of practical experience, quality of quality-based, market demand-oriented, won recognition at home and abroad and support. ?????? Various cooling techniques such as water-cooled, frozen and dipped in boiling cooling cycle and so may be used to solve the heat problem. Nevertheless, the heat sink is still the most economical and most reliable cooling. The following is a description of the factory in Zhuhai fin heat sink material: the traditional heat sink material is aluminum, aluminum thermal conductivity of up to 209W / mK, good processing characteristics, low cost, and therefore a very wide application. And because the heat sink performance requirements are high, so the heat transfer characteristics of the heat sink material requirements are more ardent, demand a variety of high conductivity material is also increasing. The thermal conductivity of 390W copper / mK, compared to 70% increase in aluminum conduction, but the disadvantage is the weight of three times the aluminum, and the same price per pound of aluminum, and more difficult to process. Due to limited restrictions on high-temperature molding, the same can not be aluminum extrusion and molding, and machining of copper to spend more time to make the process easier to damage equipment. However, when the application is limited by the conduction properties of the occasion as the focus, the copper is usually used as an alternative use, in addition to the bottom of the use of copper as a heat sink can improve the efficiency of heat transfer diffusion, reducing thermal resistance. Some promotional materials such as high thermal conductivity heat of polymer, carbon substrate compounds, metal powder sintering, diamond and graphite compounds are currently the subject of attention of a thermally conductive material. AlSiC is the latest material, mixing the various aluminum alloy to form special physical properties, controlled thermal expansion, high conductivity, and the strength of such AlSiC significantly more attractive, because of cost, this material is generally used in bottom and bottom as the power modules and direct contact with the substrate wafer. Dongguan Branch heatsink manufacturers through quality system implementation, continuous improvement organizational culture and human behavior in order to achieve the products and services to meet customer wants for the purpose.
