fundas eva de alta calidad

Las fundas de EVA se fabrican mediante técnica de termoformado. El primer paso es elegir los materiales de superficie y revestimiento. Luego, estos materiales se laminan junto con una lámina de EVA intercalada para crear una lámina compuesta.  Una vez que la hoja está lista, se corta al tamaño adecuado para formar la caja.  Luego, las láminas laminadas se calientan en un horno para ablandarlas.   La lámina calentada se coloca sobre un molde de EVA (con la forma de la carcasa final del estuche).  Se aplica un vacío para eliminar el aire atrapado y colocar el material firmemente en el molde, a veces con la ayuda de aire presurizado. Este proceso da forma a la lámina laminada según los contornos detallados del molde. Después de un breve ciclo de formación, se aplica una ráfaga de presión de aire inversa desde el lado de vacío para romper el sello de vacío y ayudar a liberar las piezas formadas del molde a medida que se abre el herramental.  El siguiente paso es organizar el recorte del exceso de material y cortar el caparazón para coserlo.  Después de eso, nuestro personal de control de calidad inspeccionará cada capa individualmente. Las carcasas que pasen la inspección serán enviadas a nuestro taller de costura para el proceso de costura y ensamblaje.   Una vez que se complete todo el producto, nuestro equipo de FQC se encargará del corte del extremo del hilo de coser e inspeccionará cada producto individualmente. Sólo aquellos que cumplan con nuestros estándares de calidad pasarán a la siguiente etapa.  Los productos que cumplan con nuestros estándares de calidad se colocarán en bolsas de plástico y se empaquetarán en cajas de cartón para exportación. Luego organizaremos el método de entrega según la solicitud del cliente.
