Choosing the Right Manufacturing Process & Avoiding Production Bottlenecks (DFM, Capacity, and Line Balancing)

32 minutes

How do you choose the right manufacturing process and avoid production bottlenecks? Adrian and Paul explain how volume, materials, tolerances, and cost determine whether to use injection molding, CNC machining, or die casting. They also cover common bottlenecks, including supplier capacity limits, component shortages, and assembly line imbalances, and how Design for Manufacturing (DFM) helps prevent delays and reduce production risk.
