Basic Design of Graphite Moulds for Pressure Sintering
The article to be sintered is simultaneously heated and subjected to pressure (F) in a graphite Mould. Heating can be arranged by direct passage of current or by induction.
The Filing Space (5) is formed between the mould (4) and the plungers (3) and can be varied in form and volume.
The water cooled brass contacts(1) reduce heat transference to other equipment. The graphite contacts(2) act as conductors for electric current and at the same time exert pressure on the plungers (3).

Resistance Heating

• Through The Plungers : The plungers are in the electric circuit. The temperature over 1000^oC it is desirable to heat through the mould to achieve an even flow of current and heat. This avoids difficulties with conduction through plunger and mould, which can sometimes have a negative one-sided current flow, especially if a non-conductive component is being sintered.
• Through The Mould : In this case the mould is in the electric circuit and heat builds up in this and is conducted to the component being sintered.
