One-Piece Flow vs Batch vs Cellular Assembly for CKD Lines

Once your CKD kit arrives, the way you organize assembly determines your throughput, quality, and labor cost. Three production models dominate — one-piece flow, batch, and cellular — and each suits a different stage of your business. Here is how to choose.

One-Piece Flow

Each stove moves continuously from station to station, with every worker doing one step before passing it on. This minimizes work-in-progress, surfaces defects quickly, and keeps lead time short. It is the leanest model, but it demands balanced stations — a slow step bottlenecks the whole line.

Batch Assembly

Workers complete the same operation on a batch of stoves before the batch moves to the next step. Batch suits low-skilled workforces and makes training easier, but it hides defects until the batch is inspected and ties up more work-in-progress and space.

Cellular (Work-Cell) Assembly

A small team builds a complete stove within one cell, rotating tasks and owning quality end-to-end. Cells are flexible, build worker skill, and are ideal for multiple models or lower volumes. They sacrifice some raw throughput for adaptability and ownership.

How to Decide

• Start with batch or cells — lower skill barrier while you train workers.
• Move to one-piece flow — once your line is stable and demand is steady.
• Keep cells — if you run several stove models in small quantities.
