Abstract

Máquina de moldeo con inyección de gas. Una máquina de moldeo con inyección de gas provista de placas superior e inferior combinadas entre sí para formar una cavidad en el centro de las mismas, y de una estrecha puerta para permitir que la resina fundida sea pulverizada a alta velocidad durante la inyección por gas, incluyéndose un resalte destinado a reducir la velocidad del flujo de resina a través de la puerta y propagar la resina en todas las direcciones en el momento en que la resina es impactada por el resalte, siendo seguidamente nebulizada hacia la cavidad y evitándose así el fenómeno de chorro, un defecto que se forma en la superficie externa de la pieza moldeada. Figura 3.
