Product Overview
The Magnetic Closure Box with Die-Cut Insert for electronics accessories by Guangdong Bincai Color Printing Co., Ltd. delivers premium protection and unboxing experience for high-value electronic products. Founded in 2003 and featured in China Print & Packaging News as a leading rigid-box manufacturer, Bincai operates an ISO 9001:2015 and FSC-certified facility with a daily output capacity of 1.7 million color boxes plus 220,000+ gift boxes.
Precision Manufacturing & Equipment
Each box is printed on the KBA Rapida 105 4-color offset press at 15,000 sheets/hour for photographic-quality CMYK reproduction, with specialty UV effects applied on the Heidelberg Speedmaster CD 102 7+1 UV featuring inter-deck UV curing for instant-dry output and enhanced scuff resistance. Premium foil stamping is executed on the Bobst SP 102 BMA with ±0.15mm registration accuracy for gold, silver, and holographic brand logos. Die-cut foam inserts are precision-routed to cradle chargers, cables, earbuds, power banks, smart accessories, and other small electronics snugly, secured by integrated neodymium magnetic closure rated for 3–8N opening force.
Our 18,000 sqm dual-factory campus (10,000 sqm established plant + 8,000 sqm smart factory commissioned 2025) features automated guided vehicles, inline QC camera systems, and real-time production dashboards. With 23 years of expertise since 2003, we serve 60+ countries with MOQ starting at just 500 units and free pre-production samples including full magnetic function testing. The combination of rigid greyboard construction, customizable surface finishes, and exact-fit insert cavities ensures your electronics arrive protected and present with a premium tactile experience that reinforces brand value.
