The silicone or leather bellows protect the space between the eject plate and the bed plate of the powder imput, eliminating the problems involved in this process.
Silicone bellows & aluminium frame
The main difference between traditional bellows and silicone bellows lies in silicone not deforming, not degrading and repelling dust. Notable among the advantages of this type of bellows are its longer route of extraction (maximum extraction route of current presses), its better design, thereby improving its lifespan (greater thickness and double fold) and its compatibility with any other kind of manufactured mould.
In addition to the silicon bellows and eject plate, it is installed one aluminum frame to protect bellows of air extraction produced during pressing process and for protecting the bellows too, because powder accumulation around it, bellows could be damaged by the eject plate due to the motion up and down during the pressing process.
