Creating a complete and standardized tech pack is the core foundation of efficient OEM customization matched with our unified factory production system, a qualified tech pack needs to include clear product dimension drawings with precise tolerance ranges, detailed raw material composition and surface finish requirements, Pantone color codes for all custom appearances, complete logo printing or embossing specifications, packaging size and accessory matching rules, target market safety certification indicators and acceptable defect judgment standards, all content must be written with quantifiable data rather than vague descriptive language to align with our factory’s incoming material inspection, production processing and finished product testing systems, once the tech pack is confirmed by both sides it will be stored in our permanent customer file library as the sole production standard for all subsequent OEM orders of the brand, incomplete or ambiguous tech packs will trigger repeated sample modification and mass production rework that break the stable operation rhythm of the whole OEM factory system and extend overall order delivery cycles for global custom buyers.
