The Polish defence manufacture is expanding its production capacity. fresh facilities, machinery, and production lines are intended to enable the fulfillment of larger orders. However, even a crucial acceleration in welding, machining, or assembly will not increase the efficiency of the full mill if surface preparation, coating application, and drying stay unchanged. The paint shop, which has so far met the plant’s needs, may become 1 of its bottlenecks at this fresh scale of production.
