📋 Detailed configuration & labor breakdown
🔹 Minimal configuration startup · low volume · workshop
Applicable scenarios: home workshop, micro‑factory, sample room, small custom orders.
📌 Cutting: Manual cutting table (1), hand‑held electric shear (1).
👥 Operators: 15–20 (lockstitch operators also handle specialty machines).
📈 Daily output: 200–500 shirts (8h shift).
Sewing machines: 8~12 lockstitch, 1~2 overlock, 1 double needle, 1 buttonhole, 1 button sew, 1 knife folder. Pressing: 2~3 vacuum tables with steam generator, 1 collar point press. Some steps (e.g., fusing) may be outsourced.
🔸 Standard configuration mass production · OEM/ODM
Applicable scenarios: medium garment factory, brand supplier, export order lines.
Reference: a typical domestic shirt line with 3 groups (30 workers per group, total 90) yields ~2000 high‑end shirts/day. This configuration targets 600–800 pcs/day per line as a balanced setup.
Equipment list
- Cutting: auto spreader, band knife/vertical cutter, fusing machine, strip cutter, end cutter.
- Sewing: 25~35 lockstitch, 3~5 overlock, 3~4 double needle, 2~3 buttonhole (straight/eyelet), 2~3 button sew, 2~3 knife folder, 2~3 bartack, collar turner, collar former, placket machine, 2~3 hem folder attachments.
