Abstract

Quick mix casting process for prodn. of body parts for heating appliances, esp. radiant panels, uses a casting resin system comprising XD 5250 (RTM: epoxy resin), prefilled and mixed under vacuum, XD 5200 (RTM: hardener) and DY 5200 (RTM: accelerator). Pref. resin XD 5250 (RTM), prefilled and mixed under vacuum with hardener Xd 5200 (RTM) and accelerator DY5200 (RTM), is cast under pressure at 120 deg C +/- 20 deg C into a mould, hardened for 2 hrs. at 120 deg C. and then for 2 hrs. at 135 deg C., demoulded and post cured for ca. 10 hrs. at room temp.

Description

DESCRIPTION
La présente invention est créée d'un souhait de fabriquer des carrosseries d'appareils de chauffage notamment pour des PANNEAUX RAYONNANTS pouvant allier simultanément: - I'obtention de formes irréalisables en acier, - de produire une carrosserie répondant aux normes en vigueur, - de garantir une résistance mécanique et thermique compatible avec l'utilisation de l'appareil, - de fabriquer un produit fini en une seule opération, - de fabriquer tous types et modèles d'appareils de chauffage utilisant ce procédé.DESCRIPTION
The present invention is created out of a desire to manufacture the bodywork of heating apparatuses in particular for RADIANT PANELS which can combine simultaneously: guarantee mechanical and thermal resistance compatible with the use of the appliance, - manufacture a finished product in a single operation, - manufacture all types and models of heating appliances using this process.

La présente invention permet de confirmer que l'ensemble des critères énuméré ci-dessus sont remplis. The present invention makes it possible to confirm that all of the criteria listed above are met.

L'invention consiste à utiliser une résine coulée du type de la série XD 5250, préchargée et mélangée sous vide, d'un durcisseur du type de la série XD 5200 et d'un accélérateur du type de la série DY 5200.  The invention consists in using a casting resin of the XD 5250 series type, preloaded and mixed under vacuum, of a hardener of the XD 5200 series type and of an accelerator of the DY 5200 series type.

Ensuite d'effectuer le coulage sous pression dans un moule à 1200C avec possibilité de variation de + ou - 20"C en température. Then carry out the pressure casting in a mold at 1200C with possibility of variation of + or - 20 "C in temperature.

Après durcissement de 2 heures à 1200C, puis 2 heures à 135"C, s'effectue le démoulage qui sera suivi d'un temps de post durcissement à température ambiante. After hardening for 2 hours at 1200C, then 2 hours at 135 "C, demolding takes place which will be followed by a post-hardening time at room temperature.

Ce temps de post durcissement peut être modifié si la température a une variation de + ou 20"C. This post-curing time can be modified if the temperature has a variation of + or 20 "C.

Pour une résine de coulée de 1200C, le temps de post durcissement est de 10 heures à température ambiante. Néanmoins, il peut être modifié et adapté en fonction des températures choisies. (Variation de + ou - 20"C, température de coulée). For a 1200C casting resin, the post-curing time is 10 hours at room temperature. However, it can be modified and adapted according to the temperatures chosen. (Variation of + or - 20 "C, casting temperature).

Ce système permet: - de satisfaire des formes exigeantes, - de supprimer tous les sous postes de fabrication tel que le précoupage, le perçage, etc...  This system makes it possible: - to satisfy demanding shapes, - to eliminate all manufacturing sub-stations such as pre-cutting, drilling, etc ...

- de supprimer également les postes de finition: peinture, émaillage ou autres postes, - de réduire d'environ 40% I'investissement moule. - also to eliminate finishing stations: painting, enamelling or other stations, - to reduce mold investment by around 40%.

En conclusion, le présent dépôt de brevet consiste à garantir le procédé de fabrication de carrosseries pour panneaux rayonnants selon le système connu sous la dénomination "QUICK MIX CASTING" avec l'emploi de la résine coulée du type de la série XD 5250 pour la fabrication d'appareils de chauffage, qui offre des avantages indéniables par rapport aux constructions traditionnelles de même type, ou autres existants. Le nom du fabricant des produits
XD5250, XD 5200, DY5200 est CIBA-GEIGY. In conclusion, this patent application consists in guaranteeing the process for the manufacture of bodies for radiant panels according to the system known under the name "QUICK MIX CASTING" with the use of cast resin of the type of the XD 5250 series for the manufacture heating appliances, which offers undeniable advantages compared to traditional constructions of the same type, or other existing. The name of the manufacturer of the products
XD5250, XD 5200, DY5200 is CIBA-GEIGY.
