Designed for press agglomeration, compacting, and briquetting operations, there are a variety of screw and roll compactors configurations available to optimize each process. A hydraulic measuring device indicates press force and will automatically regulate feed rate to maintain preset pressure limits-a feature incorporated into the design of our roll compactors to ensure that sensitive products are not over pressed.

Gas Coaters

Gas Coaters are used in methods to produce thin films using solutions, suspensions or liquid precursors (chemical preliminary stage). Preferentially, it is applied for expensive or minor amounts of source solution. A solution is applied on a rotating substrate and nearly completely removed by spinning, so that only a thin film remains (see schematic view below).

Additionally, the majority of the eliminated solution can be collected and led back. Depending on the desired properties of the film the viscosity, the wetting behavior and, if necessary, the solids content will be modified.


Common Applications

  • Protective coatings (e.g. scratch resistance, diffusion barrier)
  • Transparent, conductive oxides (e.g. ZnO)
  • (Semi-) metal thin films (e.g. doped silicon films with different degrees of crystallization)
  • Masks for semiconductor industry
  • Optically active films (e.g. phosphors )
