The complete OEM customization workflow starts with clients submitting detailed product design drawings, functional specifications and brand packaging requirements to our engineering team, who first conduct technical feasibility evaluation and send cost quotation and MOQ plans within two working days, once both sides confirm the cooperation terms we arrange prototype production with physical samples delivered for client testing and revision feedback, after sample approval we launch mold manufacturing and small-batch trial run to verify mass production stability, then schedule formal bulk OEM production with real-time progress reports sent to clients every week, finished goods pass multi-layer QC testing before customized brand packaging and cross-border shipment, and our dedicated project manager stays in charge of all communication and adjustment demands throughout the whole customization cycle to avoid information deviation and delivery delays.
