The synthesis of classic and modern metal processing techniques is very suitable for making non-conventional slugs of materials and shapes previously unseen in the ammunition industry. The D Dupleks slug ammunition production process consists of many stages, from slug body lathe-machining and thermal treatment to their encasing in plastics. 

​

Compared to classic lead slug manufacturing, steel ammunition production is much more sophisticated and time-consuming process, reflected in 5-7 times higher production costs. The high production costs are minimized by almost full automation of the production process. For steel slug production, non-standard equipment is needed; it is made by D Dupleks specialists themselves. The highly automated and productive machinery is unified into a production cycle where every operation is electronically controlled.
