Shanghai Koito Automotive Lamp Co. Ltd. to improve design robustness and quality with Sigmetrix software

One of China’s largest passenger Vehicle lighting manufacturers selects CETOL 6 Sigma for Tolerance Analysis Solution

Shanghai Koito Automotive Lamp Co. Ltd. to attain design robustness with CETOL 6 Sigma McKinney, TX – January 13, 2015 – Shanghai Koito Automotive Lamp Co., Ltd., a company that has more than a 40% share in China’s passenger Vehicle lighting market, has selected Sigmetrix CETOL 6 Sigma tolerance analysis solution as an integral part of its quality production and design robustness initiative. This program is committed to meeting the requirements of their customers.

Shanghai Koito Automotive Lamp Co., Ltd. chose CETOL 6σ and also entrusted the 3D tolerance analysis team of Cybernet China to work on a few projects. After several tolerance analysis projects were completed they could see the results from CETOL 6σ were accurate and verified the resulting data in practice.

Sigmetrix, LLC developed the seamless CAD integrated software CETOL 6σ which helps the product design engineers at Shanghai Koito to improve and manage the quality level of the lamp assemblies with efficiency. “CETOL 6σ can be seamlessly integrated with CATIA and simulate the real world assembly environment. For assemblies of automobile lamps, the effect of RPS errors, welding deviations and manufacturing variations can be considered. A 3D tolerance analysis of gaps and surface differences in automobile lamps can help attain design robustness and improve production quality,” said Product Design Department Manager Qi Fan.

“We are delighted that Shanghai Koito is integrating CETOL 6 Sigma into their CATIA platform, and we’re confident that their product design engineers will achieve the design robustness and quality improvements they are looking for,” remarked Sigmetrix President Chris Wilkes. “We are pleased that our continued commitment to invest in the China market has contributed to the success of our tolerance analysis and GD&T products and proud to be a partner with Cybernet China.”
