Die casting solutions
Die casting is a highly productive casting process and has experienced something of a revival in recent years caused by the growing demand for weight reduction in the automotive industry. In order to produce ever larger structural and body parts, foundries have invested in larger die casting machines with locking forces of 4,000 t and above.
HA’s product range includes the consumables foundries need for this highly automated casting process, which is still relatively new compared to classic casting processes.
Release agents
Before each shot in the die casting process, a release agent is sprayed onto the surface of the cavity to achieve a range of functions and properties:
- Separating the aluminium or magnesium alloy from the steel die and avoiding sticking / welding by preventing the formation of an intermetallic phase like FeAl3
- Creating the lubricating effect required to eject the casting and to lubricate moving parts, such as slides and ejector pins
- Making it easier to fill the dies
- Providing additional mould cooling during spraying
Given the extremely diverse range of parts, which includes everything from solid, thick-walled parts such as cylinder crankcases to very thin-walled, flat parts such as strut brackets and A-pillars, mould release agents face many challenges.
This is why HA’s product portfolio includes release agents with a variety of compositions to ensure that we can provide the right solution for every single application.
