    • A process for producing a crosslinked molded foam which comprises: (1) a preceding step in which a thermoplastic elastomer composition which is a material for crosslinking foaming is introduced in a given amount into a first cavity space in a mold; (2) a first step in which the thermoplastic elastomer composition is foam-molded in the first cavity space with heating and pressurizing to obtain a perform and form a skin layer on the periphery of the perform; and (3) a second step in which the perform is crosslinked and foamed with heating and pressurizing in a second cavity space which is inside the same mold and is larger than the first cavity space. By the process, sponges having the same shape as the mold can be obtained. The sponges molded hence have evenness of size, excellent thickness precision, and a moderate density and hardness. They have excellent suitability for mold design transfer. The molded articles do not necessitate additional cutting. Due to this, the production steps are simple and excellent profitability is attained because of no loss. The process can conform to various designs to give a highly functional molded foam such as a shoe sole.
    • 一种交联成型泡沫体的制造方法,其特征在于,包括:(1)前述工序,将作为交联发泡材料的热塑性弹性体组合物以规定量引入模具中的第一空腔内; (2)第一步骤,其中热塑性弹性体组合物通过加热和加压在第一腔空间中发泡成型,以获得表演并在表演的周围形成皮肤层; 和(3)第二步骤,其中所述作用在同一模具内部并且大于所述第一空腔空间的第二空腔中通过加热和加压而交联和发泡。 通过该方法,可以获得与模具相同形状的海绵。 因此,模制的海绵具有尺寸均匀性,优异的厚度精度和适度的密度和硬度。 它们具有极佳的模具设计转移适用性。 模制品不需要额外的切割。 由于这样,生产步骤简单,因为没有损失而获得了优异的盈利能力。 该方法可以符合各种设计以提供高功能的模制泡沫如鞋底。
