The OEM / ODM Custom Production Process, Step by Step
From requirements and tech pack to sampling, cutting, sewing, QC and shipping — how a custom tactical vest actually gets made.
Requirements and the tech pack
The first hurdle in custom production is making the requirements unambiguous. Professional buyers provide a tech pack specifying fabric, weight, colors, prints, embroidery, size charts, hardware brands and packaging. The more complete the tech pack, the more accurate the quote and sampling, and the fewer disputes later.
Without an existing spec, the factory guides you through each detail until it becomes an executable specification document.
- Fabric: material, denier, coating, colors
- Pattern and sizing: size chart and per-size quantities
- Hardware: buckle, zipper, webbing and hook-and-loop brands and specs
- Print and embroidery: placement and colors for screen print, heat transfer, embroidery
- Packaging: hang tags, care labels, bags, carton packing
Sampling: the last check before production
Once the spec is confirmed, sampling begins. The sample exposes every issue in pattern, color and workmanship, usually taking one to two adjustment rounds. Before mass production, always confirm an approval sample — it becomes the benchmark for later inspection, and bulk quality is judged against it.
Cutting and sewing
Cutting is either die-cut or laser-cut: die cutting suits high volume at low cost; laser cutting offers precision and sealed edges for complex shapes and laminates. Sewing is the heart of quality — stress points get bar-tacks and Box-X reinforcement, with standards for stitch density, thread and seam type. Professional factories use dedicated machines (bar-tackers, buttonholers, four-thread overlockers) for batch consistency.
Thread is usually bonded nylon (T70/T90) — high strength, abrasion-resistant, and unlikely to unravel.
QC and shipping
Quality control uses AQL sampling standards (ISO 2859-1 / ANSI ASQ Z1.4), with multi-stage inspection from incoming fabric through cut pieces and semi-finished to finished goods to keep defect rates low. After passing QC, orders are packed, cased and shipped on the agreed schedule. Across the whole flow, the spec sheet, approval sample and AQL are the three things that determine final quality.
As a factory with 15 years focused on vest production, our edge is standardizing this entire process so OEM/ODM clients can relax.
