Definitions
- the invention relates to a device for compressing flowable solids, especially powdery solids, with shaping press tools.
- the pressing devices presses the powdery solid or pasty substance pressed under high pressure to form a mechanically stable molded body or compacted.
- the pressing tools must be designed that they can absorb the high press forces.
- the shaping Surfaces must be extremely smooth so that the powdery or pasty substance does not adheres to the surfaces, which greatly reduces the quality of the moldings with regard to their surface quality and mechanical stability would have.
- the shaping surfaces are customary hard chrome plated or made of polished hard steel.
- the invention has for its object to improve the physical surface properties of the pressing tools so that even with critical, tending to caking flowable solids, the shaping surfaces remain clean and residue-free during operation and operational failures caused by attaching product to the shaping surfaces are safely avoided.
- flowable solids are understood here to mean powdery, free-flowing solids or semi-solid, pasty substances.
- a device for pressing flowable solids which has pressing tools with shaping surfaces, at least the shaping surfaces are provided with a diamond-like, amorphous carbon layer.
- This layer is briefly referred to below as DLC layer ".
- the layer thickness of the DLC layer is preferably 1 to 10 ⁇ m.
- stamp head and possibly also the Stamp stock will be remunerated.
- the DLC-coated tablet stamp also enables implementation of special geometrically complex tablet shapes, e.g. Polygons or toroids.
- the friction of the tablet stamp in the die can be reduced, if in addition the surface of the shaping part of the tablet stamp with the DLC layer is remunerated.
- the head and the shaft of the stamp provided with a DLC layer will be reduced.
- the shaping part 4 is the one that determines the tablet volume Cavity 5 (dashed) incorporated.
- the surfaces of the cavity 5 are the shaping surfaces if the upper and lower stamps are used during the pressing process driven into the die of the tablet press and pressed against each other.
- the lateral limitation of the tablets is done in a known manner by the cylindrical inner surface of the die opening (not shown).
- the shaping Surfaces of the cavity 5 and the lateral lateral surface 6 on the stamp 3 are included an approx. 2.5 ⁇ m thick diamond-like, amorphous carbon layer (DLC layer) overdrawn.
- DLC layer amorphous carbon layer
- This coating takes place, for example, in a two-stage process, in the first stage galvanically one of chrome and diamond particles existing dispersion or diffusion barrier layer and in the second step with the help of the CVD process (Chemical Vapor Deposition) a CVD diamond layer on the shaping surface and deposited on the lateral lateral surface 6 of the stamp becomes.
- CVD process Chemical Vapor Deposition
- the same coating can be applied to the stamp head 1 and possibly also the stamp shaft 3 are applied.
