Abstract

1. UN PROCESO DE CO-TERMOFORMACION PARA PRODUCIR UNA LAMINA DE ESPUMA TERMOPLASTICA TERMOFORMABLE QUE COMPRENDE LAS ETAPAS SIGUIENTES: a. PRODUCIR UN NUMERO DE CAPAS DELGADAS DE ESPUMA DE POLIESTIRENO EL ESPESOR TOTAL DE LAS CUALES IGUALA ESENCIALMENTE EL ESPESOR TOTAL DE LA LAMINA QUE HA DE SER TERMOFORMADA EN UN PRODUCTO PRESENTANDO CADA UNA DE DICHAS CAPAS UNA INTERFACE A LA OTRA, b. PONER DICHAS CAPAS DE ESPUMA DELGADA EN ESTRE- CHA PROXIMIDAD EN SUS INTERFACES PARA FORMAR DICHA LAMINA, c. CALENTAR DICHA LAMINA HASTA UNA TEMPERATURA DE TERMOFORMACION, d. TERMOFORMAR LA LAMINA EN PRODUCTOS DE UNA CON- FIGURACION DESEADA CON DICHAS CAPAS ADHERIDAS EN- TRE SI, Y e. ARREGLAR Y RECOGER DICHOS PRODUCTOS TERMOFOR- MADOS. FIGURA 11. A CO-THERMOFORMATION PROCESS TO PRODUCE A THERMOFORMABLE THERMOPLASTIC FOAM SHEET THAT INCLUDES THE FOLLOWING STAGES: a. PRODUCING A NUMBER OF THIN LAYERS OF POLYSTYRENE FOAM THE TOTAL THICKNESS OF WHICH ESSENTIALLY EQUALS THE TOTAL THICKNESS OF THE SHEET TO BE THERMOFORMED IN A PRODUCT PRESENTING EACH OF THESE LAYERS ONE INTERFACE TO THE OTHER, b. PUT THESE LAYERS OF THIN FOAM IN CLOSE PROXIMITY AT THEIR INTERFACES TO FORM SUCH A SHEET, c. HEATING SUCH A SHEET TO A THERMOFORMING TEMPERATURE, d. THERMOFORM THE SHEET IN PRODUCTS OF A DESIRED CONFIGURATION WITH SUCH ADHESED LAYERS BETWEEN YES, AND e. ARRANGE AND COLLECT THESE THERMOFORMED PRODUCTS. FIGURE 1
