La \u00abCeramic ShellCasting\u00bb o Cascarilla Cer\u00e1mica, como su nombre indica, es una de las variantes de la llamada fundici\u00f3n de revestimiento por capas. <\/p>\n\n\n\n
Ofrece, entre otras, ventajas en su modo de aplicaci\u00f3n. Se trata de una papilla densa o mezcla que se aplica a base de capas sobre el modelo perdido a reproducir, dej\u00e1ndolo secar se endurece para conformar un molde poroso y resistente <\/p>\n<\/div><\/figure><\/div>\n\n\n\n\n\n\n\n

No se les a\u00f1ade respiraderos, ya que el molde en s\u00ed respira por toda su superficie y facilita la entrada del metal sin que aparezcan las tan temidas bolsas de aire. La resistencia permite que los bebederos sean directos, finos y con poco n\u00famero, seg\u00fan las necesidades de la pieza<\/p>\n\n\n\n

CHOQUE T\u00c9RMICO (Ing.Flash Dewaxing)<\/em> Consiste en calentar un horno previamente (entre 600\u00baC y 800\u00baC) e introducirlo la pieza r\u00e1pidamente, con la intenci\u00f3n de crear una junta de dilataci\u00f3n entre el modelo de cera y el molde, es decir, un peque\u00f1o espacio que d\u00e9 cierto margen de dilataci\u00f3n al resto de masa de cera que compone el modelo y que inevitablemente se expande al someterlo a tan altas temperaturas.<\/p>\n<\/div><\/figure><\/div>\n<\/div>\n<\/div>\n\n\n\n

FUNDICI\u00d3N<\/strong><\/h4>\n\n\n\n
El proceso de metal fundido se realiza en dos habit\u00e1culos t\u00e9rmicos diferentes. De un lado, el horno donde se funde el metal y de otro, una mufla que alberga los moldes refractarios. Pues estos deben estar calientes para recibir el metal fundido. Se trata de una t\u00e9cnica de modelo perdido y molde perdido, ya que tanto el modelo, normalmente en cera, se eliminar\u00e1 para obtener su cavidad y el molde, una vez llenado, se romper\u00e1 para obtener la pieza fundida.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
