Abstract
In an injection foam molding method, a relationship between a flow front moving speed (cm/s) of a foamed resin material in an injection step of injecting the foamed resin material into a cavity and amount of gas generated per 1 g of a resin material (ml/g) is defined as follows: the amount of gas generated per 1 g of the resin material is 0.36 ml/g or more; and the flow front moving speed (cm/s) is 75×the amount of gas generated per 1 g of the resin material (ml/g)−35 or more and 12 cm/s or more.
