Company Information

Message from the president

As a company, we have ever pursued carefully what is “what it should be” as a manufacturing industry.
Beginning with the casting industry, we have continued running by expanding the range from casting to processing, to molds, to assemblies, and to advance into China, while thinking first that we become the company customers always want to order.

We have been expanding our business to China for about 30 years and we have also worked to hire and focused on nurturing local employees. In 2006, We launched mold and processing factory, Zhengzhou Nissin Seiko Co., Ltd. with a 100% equity investment.
In 2010, We have newly established “Zhengzhou Rishin Precision Machinery Co., Ltd.”, which are working on integrated production from mold for aluminum die casting and aluminum gravity casting. We also began manufacturing and selling from aluminum gravity machines and shell machines.We are constantly expanding the range of manufacturing to pursue improvement of productivity.

Company policy

『Creating new value』

There is a limit to getting customers happy with price competition of ready-made goods alone.
We have established a consistent production system from design and manufacturing to quality control.
We have proposed the most efficient “Monozukuri” (manufacturing), while maintaining functionality and quality to meet with customers’ difficult demands. Also, taking advantage of the network and organizational capabilities of the group network including the Chinese factory, it is possible to achieve substantial cost reduction with a different approach.
We always propose ourselves and create new value. That is fundamental concept of our company.
