Abstract
Un método de moldeo por inyección de resina de moldear una resina mediante llenado por inyección del interior de una cavidad de molde, que está formada por sujeción de molde de un par de molde de superficie de diseño y molde de superficie que no es de diseño, con una composición de resina de polipropileno termoplástico fundida, el método incluye: establecer una temperatura de cada una de las superficies que forman cavidad del molde de la superficie de diseño y el molde de superficie que no es de diseño antes de llenado por inyección a 60°C a 120°C y ajuste de la temperatura de la superficie de formación de la cavidad del molde de la superficie de diseño para que sea mayor que la temperatura de la superficie de formación de la cavidad del molde de superficie que no es de diseño por 5°C a 50°C; y hacer que la presión de la resina llegue a una presión negativa dentro de los 7 segundos después de completar el llenado por inyección de la composición de resina de polipropileno termoplástico, en donde la composición de resina de polipropileno termoplástico contiene una resina de polipropileno cristalino y un componente de hule y un contenido del componente de hule es 1% en masa a 40% en masa.
