PRODUCTION TECHNOLOGY:

SAND CASTING - sand casting technology uses two means of shaping, manual and mechanical. Manual shaping is suited for castings of greater dimensions, higher weights and for more complicated castings. Mechanical shaping on the other hand guarantees higher labour productivity, casting precision and also stable conditions during production.

SAND CASTINGS

CASTING MATERIALS AND THEIR CHARACTERISTICS:

Casting material:	CSN 424331 AlSi₁₀MgMn	CSN 424357 AlCu₄Si₅Zn	CSN 424384 AlSi₁₀CuMn	UNIFONT 90 AlZn₁₀Si₈Mg
Hardness:	50 HB	70 HB	50 HB	100 HB
Tensile strength:	137 MPa	140 MPa	120 MPa	167 MPa

We are able to produce a wide range of Al alloys and then check the composition with SPECTROLAB M8.

MEANS OF SHAPING AND PRODUCTION PARAMETERS:

Means of shaping:	A. manual	B. mechanical
Casting weight:	0,03 - 300 kg	0,03 - 15 kg
Max. dimensions of castings:	1.500 x 1.500 mm (above standard also other dimensions)	600 x 460 x 250 mm
Efficient series:	up to 100 pieces	over 100 pieces

CAPACITY:

15 tons/monthly

USAGE:

E.G.: flanges, transmission cases, belt holders, fan parts, manual wheels, covers and artistic castings (lattices, plaques, benches, pedestals etc.).

ARTISTIC ALUMINIUM CASTINGS:

Artistic castings from Al alloys are poured into imported special sand mixtures.

FINISHING TREATMENT:

We can deliver the castings heat treated (tempered) or/and surface treated (ground, blasted with steel bullets etc.). Other treatment (e.g. galvanizing) can be provided in cooperation with our long-term partners.
