Diecasting tools
|
|
|
The tools required for diecasting are manufactured in toolmaking or mouldmaking shops.
As a basic material for the diecasting moulds usually hot work steels according to DIN EN ISO 4957 are used.
As a process diecasting is industrially used for manufacturing parts and products.
In the process the melted mass of a non-ferrous metal alloy is pressed at a high pressure of about 10 to 200 MPa and at a very high velocity of up to 120
metres/s into a diecasting mould where it solidifies. What is particular about diecasting is that a permanent mould is used. Therefore, in a series of
identical parts the mould only has to be produced once - however, this involves considerably higher expenditure in manufacturing. Through this a large
output can be achieved. This is true in particular in hot-chamber diecasting machines; the gooseneck and thus the push-out ram accumulator of these machines
are permanently covered in
the melt (which is possible only with very low-melting metals).
