Sink manufacturing section with strong technology strength now mainly produces many aluminum alloy sinks of BFD series, BF series, BF-W series and R series and other aluminum electric machine shells whose products are widely used for transducers, soft starters, spacers, high power electric supply modules, mobile station power supply, parts of solid relays and rectifiers. Now it exploits many new products including CPU sinks, super-sized section profiles (400-450mm) and other accurate aluminum alloy sink profiles. Besides these, it still can design and manufacture new type of sinks.
