Del CAD a la realidad: Proceso OEM completo de JINGYING para la producción de aretes personalizados de clientes estadounidenses

Resumen ejecutivo

This 5,000-word technical whitepaper documents JINGYING Jewelry Manufacturing’s end-to-end OEM service for a U.S.-based fashion brand’s custom earring collection. El estudio de caso examina cómo los diseños CAD de un cliente estadounidense se transformaron en 12,000 pares de aretes terminados, destacando:

  • Cross-border design collaboration protocols

  • Technical adaptations for mass production

  • Quality assurance systems meeting U.S. market standards

  • Logistics solutions for trans-Pacific jewelry shipping
