Disposable Plungers

The key features include better heating transfer during press cycles and quicker heat dissipation during cooling. Additionally, no separator is needed when pressing lithium disilicate, and no pre-heating is required. It’s easy to use, simply discard after use, and there’s no need for cleaning pressed residue, which eliminates failure due to deformation or contamination from repeated usage.

The disposable plungers on focus on reducing ring cracking, plunger flash, press rod contamination, and reaction layer formation. Meanwhile, aim to maximize uniform applied pressure to the ingot, achieve complete presses, and ensure process consistency.

Zubler® Disposable Plungers unique material components, prevent stress fractures in the transition region between the ingot and press plunger that would otherwise be transmitted through the ingot, to the sprue and into the work. Do not stick to the press rod or pressed unit due to remaining pressed residue unlike alox plungers, and do not get deformed from repeated sandblasting that can cause cracking, unlike alox plungers.

Many different pressable materials and systems require a variety diameters and lengths. Zubler® disposable press plungers provide the ideal solution, to give your pressings the best results and to avoid the problems that occur with the use of alumina oxide plungers. In multiple diameters; 12mm for tradition press ceramics and press-to, 13mm for lithium disilicate and lithium silicates and 16mm for large 5g ingot sizes, and in multiple lengths for multiple process. The table below lists the corresponding disposable plunger for the associated process.


Zubler® Disposable Plungers are available in different sizes for different applications.

  • Ø 12mm (50 Count)
  • Ø 13mm (50 Count) – For Lithium Disilikat Ingots
  • Ø 13mm, Short (50 Count) – For IPS e.max® Press Multi*
  • Ø 16mm (28 Count)
