Related Cases

A renowned trading card manufacturer in Zhejiang, China, producing lightweight anime and game cards for Japan and Western markets, implemented Samegram’s high-precision checkweigher with a push-rod rejector system. The cards, weighing under 20g per pack, required ±0.2g packaging accuracy. Manual inspection was inefficient and error-prone. Samegram’s dynamic checkweigher (±0.1g) with a ±50ms precision rejector enabled real-time defect removal at 120 packs per minute, with MES integration for full traceability. As a result, the good product rate rose above 99.8%, customer complaints dropped, and the client passed international quality audits with improved efficiency and brand trust.
