We entrust the construction of new patterns and the modification of existing ones to selected, reliable suppliers. We use patterns in wood, resin, aluminium and polystyrene. Our pattern warehouse manages over 5,000 codes.
Fonderia Augusta is equipped to make cores by both shell-moulding and cold box processes. Moulding with flasks is carried out on two lines - one semi-automatic and one manual - with 6 and 15 ton/h mixers. The use of sodium silicate as a binder allows for better quality carbon steel castings and no surface contamination of low-carbon materials, ensuring reduced environmental impact and protection of workers’ health.
The assembly stage involves cores positioning and moulds closing. This stage ends with the automated storage of the moulds in an underground deposit able to hold over 500 units.
The moulds are brought to the surface by the management system and arranged on the casting line. The laboratory processes the chemical analysis of the load, verifies it, and the operators proceed with casting. The induction furnaces and casting line are equipped with a fume suction system. After casting, an automated handling line moves the moulds to the underground storage and cooling plant, which is also equipped with a suction system.
After cooling, the company management system activates moulds movement, bringing them to the surface for the shakeout process. The castings are then shot-blasted and moved to the finishing department for feeders removal, grinding and a second shot-blasting. Fonderia Augusta uses welding processes that are qualified according to ASME BPVC Sect. IX, EN ISO 15614, EN ISO 11970 standards and employs welders who are qualified according to the requirements of ASME BPVC Sect. IX, EN 287-1 and EN ISO 9606-1.
The heat treatment of the castings is carried out in accordance with reference standards and customers’ specifications. Fonderia Augusta has three heat treatment furnaces with a capacity up to 6,000 kg and a maximum temperature of 1260°C.
Fonderia Augusta performs non-destructive tests in several platforms specifically equipped for Magnetic tests, Penetrant tests, Hydraulic tests and Ultrasound inspections. We also rely on selected laboratories for Radiographic checks, PMI and mechanical tests.
