Removable liners, which can be disassembled while the mold is still mounted in the press, have increasingly replaced fixed liners in many cases.
They offer several advantages over fixed liners. Notably, they are usable for 100% of their real lifespan, can be replaced in case of accidental breakage on-site (avoiding the need to send the mold to the workshop), and allow for format changes with similar or different shapes in the same mold (providing greater versatility).
These are liners that can be disassembled as a whole within the press, without needing to send the mold assembly to the workshop.
Removable liners allow a single die box to be adapted to different formats with a simple liners change. They are particularly suitable for small and medium formats.
In many cases, these liners have replaced fixed liners due to their numerous advantages.
These liners are made from a tempered steel support with a coating or insertion of tungsten carbide sheet.
Tungsten is a metal three times stiffer than steel, much denser than titanium, and has a hardness between 8.5 and 9.0 on the Mohs scale, making it almost as hard as diamond.
They are either fixed or removable liners with a Rockwell hardness of 75 to 85 HRC in their pressing zone, capable of withstanding between 3 and 4.5 million pressings, extending their lifespan by 500%.
