Description

Verfahren zyum Herstellen von Gegenständen aus gehärtetem Kunstharz oder gehärtetes Kunstharz enthaltenden Massen Es ist möglich, beliebig lange Preßstücke beliebiger Querschnittsgestalt aus gehärtetem Kunstharz und gehärtetes Kunstharz enthaltenden Massen dadurch herzustellen, daß die ungehärtete Masse durch beiderseitig offene Formkanäle hindurchgepreßt wird, wobei der zur Pressung notwendige Gegendruck durch eine Klemmwirkung hervorgerufen wird, die am Austrittsende des Formkanals auf den Preßling, z. B. durch einstellbare Klemmbacken, ausgeübt wird.Process for making objects from hardened synthetic resin or hardened synthetic resin-containing masses It is possible to produce pressed pieces of any length any cross-sectional shape made of hardened synthetic resin and hardened synthetic resin containing masses to produce that the uncured mass through both sides open mold channels is pressed through, with the counterpressure necessary for pressing is caused by a clamping effect at the exit end of the molding channel on the compact, e.g. B. is exercised by adjustable jaws.

Gemäß der Erfindung werden als Ktmstharzmasse für solche Verfahren die an sich bekannten selbstschmierendenKunstharzmassen benutzt. Zwar wird durch die Benutzung dieser selbstschmierenden Massen die Reibung der Masse ,an den Innenteilen des Formkanals verringert. Gerade dies ist aber, wie gefunden wurde, günstig, da die Klemmwirkung 'sonst derart unregelbar ist, daß die Eigenschaften des Enderzeugnisses erheblich beeinträchtigt werden können und selbst bei zu stark anwachsender Reibung,infolge Festbackens und Festklebenseinzelner Teilchen an den Innenteilen des Formkanals die Klemmwirkung und also der ,Gegendruck so stark werden kann, daß die gesamte Preßvorrichtung beschädigt und sogar zerstört werden kann.According to the invention, as Ktmstharzstoff for such methods uses the self-lubricating synthetic resin compounds known per se. Although it is through the use of these self-lubricating masses reduces the friction of the mass on the internal parts of the molding channel is reduced. But it is precisely this that is favorable, as has been found the clamping effect 'is otherwise so unregulated that the properties of the end product can be significantly impaired and even with excessive friction, as a result Caking and sticking of individual particles to the inner parts of the molding channel the clamping effect and thus the counter pressure can be so strong that the entire Pressing device can be damaged and even destroyed.

Alle diese Übelstände werden vermieden, wenn ein selbstschmierendes Kunstharzmaterial verwendet wird. Die Reibung im Formkanal wird gleichmäßig gestaltet und verringert. Der Druck kann also in der gewünschten Stärke eingestellt und während des Verfahrens gleichmäßig gehalten werden, da der erforderliche Gegencli uck durch eingestellte Klemmvorrichtungen am Austrittsende des Formkanals geregelt wird und eine ungeregelte Klemmwirkung, z. B. infolge Festbackens, unmöglich gemacht worden ist. Die s:elbstschmienenden Kunstharzmassen sind bekannt, bei denen härtbaren Harzen oder härtba.re Harze enthaltenden Massen Schmiermittel zugegeben sind.All of these inconveniences are avoided when a self-lubricating Resin material is used. The friction in the mold channel is made even and decreased. The pressure can thus be set to the desired strength and during of the process can be kept evenly, since the required countercli uck by adjusted clamping devices at the outlet end of the molding channel is regulated and an unregulated clamping effect, e.g. B. has been made impossible due to caking is. The self-lubricating synthetic resin compositions are known in which hardenable resins or masses containing hardenable resins are added to lubricants.

Durch das Verfahren gemäß der Erfindung werden auf unregelmäßiger Klemmwirkung und unregelmäßigem Pneßdruck beruhende 'U' belstände, z.'B. auch Ungleichmäßigkeit der Festigkeitseigenschaften, vermieden.By the method according to the invention are on irregular Clamping effect and irregular tire pressure based 'U' positions, e.g. also unevenness the strength properties, avoided.
