Often the pattern-making (since the model is very lightweight) to make room on the second floor shop, a working transportation system, preparation and storage of dry sand imposed on the outer side of the foundry (open air) and consists mainly of the bunker, pipeline equipment, made of sheet metal. This imposition of equipment saves peskooborotu shop area, and in combination with exhaust gases from the forms that are connected to a vacuum pump to fill time-solidification and improves hygiene conditions, which generally contributes to improving the culture production.

Dimensional stability model, the lack of a connector shape and consistency of process parameters allow to raise precision castings to a level equal to the precision casting investment casting (LPM).
In the mold cavity, filled with polystyrene foam, not can get foreign inclusions, which provides fewer blockages. On the surface roughness, determined largely surface roughness forms, castings castings conform to LPM. Explained This is because in both cases antipenetration paint or coating is applied to a model, not the surface form, excludes the use of rods and the assembly of the form. Weighing castings for LGM-process speaks for itself: from 0.1 kg to castings weighing several tons without any restrictions on brand alloys. In the LGM-casting process to obtain a model means already half a cast, discuss this in more detail. Current trends in production of precision spatial (three dimensional) products: models, forms, master models made of aluminum, wood, MDF, plastics and other layout related to the rapid development of computer hardware, software, digital transmission data, as well as improving the drive system of machine tools (the use of servo motors with feedback), making it accessible to the automated equipment manufacturers with a numerical program management. CNC displace virtually all other control systems on large automated factories, and the very small but very flexible generic production (Breadboard model, tool, souvenirs, advertising, repair).
