NICHIDAI mass-produces precision forgings taking advantage of technologies related to forging it has developed for many years. The company solves a variety of its customers’ problems such as small lots difficult to handle, conversion from the conventional method to forging, and special products that they cannot handle internally.
NICHIDAI also actively works on the precision forging of non-ferrous metals. Particularly, the company not only provides dies and die sets together with its technologies for high-silicon aluminum alloy scrolled parts it has successfully developed to be its proprietary precision forging process, but also mass produces those parts using its own full-scale automatic production line. The forging process using its patented “back pressure mechanism” brings advantages such as leveled height of laps. This technology is also applied to a variety of other forgings with laps.
Without back-pressure: The uneven end of the scroll causes a higher cutting cost and a lower yield.
With back-pressure: The even end of the scroll keeps the cutting cost low.
Deformation process in extrusion forging
NICHIDAI has dedicated production lines for scrolls to address their mass production and the continuous improvement of its technological ability. It also has built the same line in the factory of NICHIDAI (THAILAND) LTD. to establish the bipolar production system by Japan and Thailand.
