Safe maker Sunil Safe added AI vision inspection of painting and aims to cut defects from 3% to 0.5%

In progressCompany's own claim

Problem

Every safe Sunil Safe makes goes through a painting step, and paint defects were running at about 3%. Defective units are scrapped, which adds disposal costs for a small manufacturer.

Approach

The company, founded in 1972, had already completed five rounds of smart-factory work, including computerized systems and a manufacturing execution system. Through the AI track of the government and Samsung Electronics co-operative smart-factory program, which covers 75% of project costs up to 300 million won, it installed AI vision cameras to judge paint defects and turned the step that wipes off oil left from earlier processing into a standard recipe.

Results

Takeaway

Earlier digitization projects supplied the process data and systems for AI. The company has not reported a measured result for its 0.5% defect-rate target.
