Quantifying the “feeling” of a snap

Maruyama measures the “feeling” of a snap using defection-testing equipment to accurately achieve this most important factor of snaps for customers. This process helps us maintain top quality.

Engagement for QC Verification

QC Verification is an evaluation test of knowledge about quality control, which is conducted by The Japanese Standards Association and The Union of Japanese Scientists and Engineers under the approval of The Japanese Society for Quality Control. Many of our employees are certified, and make efforts to maintain and improve Maruyama’s “absolute quality”.
