Description

1Vletallpreßplatte für Schallplatten. Gegenüber den bekannten, zur Herstellung von Schallplatten dienenden Preßplatten, die nur mit dünnen Überzügen von Kobalt und Nickel versehen waren, um größere Widerstandsfähigkeit zu erzielen, besteht die vorliegende Preßplatte durchweg aus Kobalt-Nickel-Legierung oder einer Legierung dieser, besonders mit Chrom, Wolfram, Mangan, Silber und den Edelmetallen.1Vetal pressed plate for records. Compared to the well-known, for Production of record-serving press plates, which only have thin coatings were coated with cobalt and nickel to achieve greater resistance, the present press plate consists entirely of cobalt-nickel alloy or a Alloy these, especially with chromium, tungsten, manganese, silver and the precious metals.

Hierdurch wird der Vorteil erzielt, daß eine Preßplatte von großer Härte erhalten wird, welche außerdem auf eine genügend starke Unterlagsplatte aufgebracht werden kann, und eine größere Anzahl guter Schallplatten durch dieselbe Preßplatte hergestellt werden kann, weil trotz hoher Preßtemperatur und hohem Preßdruck die feine Gravierung nicht zerquetscht und deformiert wird.This has the advantage that a press plate of large Hardness is obtained, which is also applied to a sufficiently strong base plate can be, and a larger number of good records through the same press plate can be produced because despite the high pressing temperature and high pressing pressure fine engraving is not crushed and deformed.

Ferner braucht keine Versilberung o. dgl. wie bei Kupfer angewendet zu werden, da die verwendeten Legierungen in hohem Grade gegen schädliche Einflüsse unempfindlich sind.Furthermore, there is no need for silver plating or the like, as is the case with copper because the alloys used are highly resistant to harmful influences are insensitive.
