Abstract
A device for the manufacture of a cast, in particular a dental aid from a preheated workable substrate. The device comprises a hollow body having an essentially flat first side being provided with holes which first side is arranged to receive a model from which a cast is to be made. Said first side is adapted to cooperate with a holder-on, which seals the substrate against said first side. The body cooperated with a vacuum source that the cooperation is achieved through one to the body belonging connection being connectably arranged to an external vacuum source.
Claims6
A method for the formation of a cast from a pre-heated substrate comprising:
- providing a one-piece housing comprised of a connector integral therewith, said connector being constructed and arranged to communicate with a vacuum source that is externally positioned from said housing, said housing having a perforated top surface;
- providing a one-piece support separate from the substrate and having first and second ends;
- connecting a vacuum source to said connection;
- placing a model on said top surface;
- heating a substrate separate from the one-piece support to form a pre-heated substrate;
- placing said pre-heated substrate over said model;
- placing the second end over said pre-heated substrate;
- and
- applying a vacuum force through said housing to form a seal between said top surface, said pre-heated substrate and said second end, said vacuum force causing said pre-heated substrate to press into said model to form a cast.
A device for forming a cast from a pre-heated substrate comprising:
- a one-piece support having a first and second end, said support being separate from the substrate while the substrate is pre-heated;
- a one-piece conduit comprised of a perforated top surface, the top surface adapted to receive the one-piece support;
- and
- a connector integral with said conduit, said connector being configured and arranged to communicate with a vacuum source that is externally positioned from said vacuum conduit the cast being manufactured by placing a model on said top surface, placing the pre-heated substrate under the second end and over the model and applying a vacuum force through said conduit such that a seal is formed between said top surface, the pre-heated substrate and the second end, the applied vacuum force causing the pre-heated substrate to press into the model to form the cast,
- wherein the one-piece support comprises a cylinder.
