If you're a sportswear brand founder sourcing custom apparel, understanding OEM and ODM production workflows is non-negotiable. Many new buyers waste time and money due to unclear factory procedures, so this full breakdown simplifies every stage for your private label orders.
First, clarify your cooperation mode: OEM (Original Equipment Manufacturing) means you provide complete designs, patterns, logos and specifications, while the factory only handles cutting, sewing and packaging. ODM (Original Design Manufacturing) lets manufacturers supply ready-made styles, fabrics and patterns; you only adjust colors, prints or labels to build your brand. ODM suits startup brands with limited design teams, while OEM fits established labels with exclusive creative assets.
The official production process starts with consultation and quotation. You share your target products-gym wear, ski suits or swimwear-fabric demands, order quantity and delivery timeline. Factories calculate costs based on material, labor, printing techniques and MOQ. Next comes sample development, the most critical checkpoint. Factories produce pre-production samples for you to verify fit, fabric feel, print clarity and stitching quality. Any size or design revisions must be confirmed before mass production to avoid bulk defects.
Once samples are approved, bulk order preparation begins: raw fabric procurement, fabric pre-treatment (washing, anti-shrinking, waterproof coating for outerwear), pattern grading for multiple sizes, and cutting fabric panels. Then assembly takes place: sewing, attaching accessories like zippers, drawcords and elastic bands, heat transfer or sublimation printing, and embroidery for brand logos. Post-production covers quality inspection, stain removal, size sorting, private label tagging and custom polybag packaging with your brand print.
Finally, shipment coordination: factories arrange sea, air or express delivery according to your timeline, and provide production documents like packing lists and invoices for customs clearance.
