Description

Verfahren zur -Herstellung von Preßformen für künstliche Zähne o. dgl. Die Erfindung betrifft ein neuartiges Verfahren zur Herstellung von Preßformen, wie solche zur fabrikmäßigen Herstellung von künstlichen Zähnen o. dgl. dienen.Process for -production of molds for artificial teeth o. Like. The invention relates to a novel method for the production of compression molds, such as those used for the factory production of artificial teeth or the like.

Bisher war es üblich, die Matrizen, mit denen die künstlichen Zähne hergestellt wurden, entweder von Hand zu gravieren. oder auf galvanischem Wege zu erzeugen.Until now it was common to use the matrices with which the artificial teeth were made either to engrave by hand. or by galvanic means produce.

Beiden Verfahren haften aber gewisse Mängel an, die durch die Erfindung beseitigt werden sollen.However, both processes have certain deficiencies caused by the invention should be eliminated.

So verlangt das erstgenannte Verfahren durch Handgravierung gut geschulte und daher teuere Arbeitskräfte. Das letztere Verfahren auf dem galvanischen Wege erfordert sehr viel Zeit und auch erhöhte Herstellungskosten.So the first-mentioned procedure by hand engraving requires well-trained people and therefore expensive labor. The latter method by galvanic means requires a great deal of time and also increased manufacturing costs.

Beispielsweise sei nur erwähnt, daß mittels ,les galvanischen Verfahrens zur Erzielung eines Kupferniederschlages von i g pro qdm mindestens eine Stunde Zeit erforderlich ist.For example, it should only be mentioned that by means of the galvanic process to achieve a copper deposit of i g per qdm at least one hour Time is required.

Da aber Kupfer für den Zweck gemäß der Erfindung zufolge seiner geringen Härte nicht geeignet ist, müssen hierfür andere Metalle, wie Nickel, Stahl u. dgl., verwendet werden, (Iie noch bedeutend längere Zeit benötigen.But since copper for the purpose according to the invention is due to its low Hardness is not suitable, other metals such as nickel, steel and the like must be used. can be used (they need a significantly longer time.

Somit ergibt sich ohne weiteres, daß sich die bisher gebräuchlichen Verfahren, schon zufolge des großen Zeitverbrauches, für die fabrikmäßige Herstellung von Preßformen als nicht geeignet erweisen.It follows without further ado that the hitherto customary Process, if only due to the large amount of time required, for factory production of compression molds prove to be unsuitable.

Demgegenüber besteht das neue Verfahren darin, claß die zur Bildung der Form erforderliche Dletallschicht mittels des bekannten Spritzverfahrens auf die Form gebracht wird. Zwecks Erzielung einer fabrikmäßigen Herstellung werden die einzelnen Originalmodelle auf einer-Grundplatte in entsprechenden Abständen angeordnet und dann gemeinsam mittels des bekannten -,%letallspritzverfahrens mit Metall überzogen, so daß nach Entfernung der Form eine für mehrere Zähne bestimmte Matrize gebildet wird.On the other hand, the new method consists in the fact that the education the required metal layer by means of the known spraying process the shape is brought. In order to achieve factory production the individual original models on a base plate at appropriate intervals arranged and then together by means of the known - Metal coated so that after removal of the mold one intended for several teeth Die is formed.

Außer der Billigkeit spricht für dieses Verfahren hauptsächlich der Vorteil, daß die Herstellung der Matrizen sehr wenig Zeit erfordert, und daß die Enldresultate in bezug auf Übereinstimmung in Größe und Form die besten sind.In addition to the equity, the main arguments in favor of this method are The advantage that the production of the matrices requires very little time, and that the Final results in terms of consistency in size and shape are the best.
