High Pressure Die Casting
High Pressure Die Casting (abbreviation HPDC) is an industrial casting procedure for series and mass production of construction parts. Due to their special properties, our HOVADUR® alloys are well established in die casting for decades.
Pistons made of HOVADUR®CNCS or CCNB have significant advantages compared to steel pistons:
- Reduction of cycle time
- Increase of service life of the shot chamber
- Increase of productivity
- Reduction of costs
Futhermore, SCHMELZMETALL provides its own Piston-Adapter System with different types of adapters: HOVADUR® KAS, KAS V, KAS R and KAS RR for cold chamber die casting which provides further advantages:
- Optimized cooling due to improved circulation of the cooling agent
- Very quick replacement of pistons without special tools
- Connection between adapter and piston rod according to customer specification

Die Casting
HOVADUR® alloys are resistant against hot cracking and more effective in cooling.
Die casting is a casting procedure whereby the melt is poured or pressed into a permanent die via a sprue placed at the bottom of the die. Our HOVADUR® special alloys are essential for these dies and provide significant advantages:
- Shortened cycle times
- Extended service life of the dies
- Improved quality of the castings

Our HOVADUR® alloys are used for the following casting procedures:
- Gravity die casting: At gravity die casting the liquid metal is poured into permanent dies made of metal using the effect of gravity.
- Low-pressure die casting: At low-pressure die casting the liquid metal is poured under pressure into permanent dies made of metal.
Continuous Casting
HOVADUR® cooling dies are employed in horizontal as well as in vertical continuous casting.
Continuous casting is a casting procedure whereby the metal is poured into an opening with a defined section, the metal becoming a solid strand while passing a one-piece or multi-piece die. According to the design of the die, a distinction is made between horizontal and vertical continuous casting, the first version being applied especially for copper alloys and small size strands. Continuous casting means casting of an endless strand (steel mill). Discontinuous castings means that the length of the strand is limited by capacity of the furnace. Both procedures are employed for steel as well as for non-ferrous metals.
Furthermore, HOVADUR® alloys provide maximum cooling. Resistance against hot cracking is considerably better compared to conventional alloys.

Amorphous Metals
HOVADUR® casting wheels are employed for producing amorphous metals.
Amorphous metals are a group of alloys which - contrary to usual alloys – do not show crystalline structure, but an amorphous, disordered structure like glass (therefore also called „metallic glasses“). For the production of these metals, the melt is injected on our HOVADUR® casting wheels. The amorphous structure is the result of extremely quick cooling. This makes special demands on the casting wheels, e. g. concerning thermal conductivity, which our HOVADUR® alloys are able to meet. The same procedure applies also for e. g. brazing foil and nano-crystalline foil.
