Zakład Produkcyjny Armatury Przemysłowej AKWA Sp. z o.o. has got own Foundry equipped with 2 inductive furnances to melt metal.
The Foundry production processes management based on Integrated Quality Management System ISO 9001 : 2015.
We manufacture gray iron castings – EN-GJL200 and EN-GLJ250 and ductile iron castings – EN-GJS 500-7. In year 2008 AKWA did a great investment purchasing the biggest automatic molding machine in Europe. That is American Hunter machine with sizes: 610mm x 762mm (mould) and 585mm (height).
The investment has increased production range and possibilities. It also allows making castings very precisely with complicated shapes.
The Foundry manufactures vast number of castings for own needs and also delivers them to many countries, especially for car manufacturers, agricultural and heavy industry.
The cores are prepared in the technologies:
- method of core cold box hardened CO2,
- method of core hot box.
The raw castings are fettled from remains of the moulding sands and grinded. The sharp edges are grinded and remains of the gating system are removed. Castings can be cover by safety coatings.
The castings also go under heat treatment:
- softening glow,
- expansion glow.
