Plasticizing units especially developed by BOY are available for the processing of ceramic and metal powder. Working closely together with the users, solutions were developed which turned out to be very effective.
Small mass-produced articles and articles with complex shapes can be produced economically with these techniques.
The following process stages are involved:
- Preparing the mixture of binder system and powder
- Granulating the prepared moulding compound
- Injection moulding of a green part in the injection moulding machine
- Debinding in the oven
- Sintering by baking in an oven
The injection-moulded green parts and the so-called brown parts (after debinding) must be handled with utmost care, as the moulded parts do not possess any particular mechanical strength and can be easily damaged.
