摘要： A method for creating a hot melt foamed form for an air induction system. A block of thermal mastic elastomer is melted and blended with nitrogen gas to create a foamed material. The foamed material is applied by robotic techniques over a base material on the surface of a polypropylene glass lower shell. After the foamed material cures, a polypropylene glass cover is applied over the foamed material form to create an air tight dust/water seal. The cover does not adhere to the cured foamed material and is removable when service is necessary. The foam material can also be dispensed into a mold and then transferred to the base, allowing for changes in the shape and profile of the foamed material. This method can also be employed to create an isolation pad on an air induction system to absorb engine shock. The thermal mastic elastomer can also be employed to create a seal between the cover neck of an air induction assembly and a mass air flow sensor.
摘要翻译： 一种用于产生用于空气感应系统的热熔泡沫形式的方法。 将一块热弹性体弹性体熔融并与氮气混合以产生泡沫材料。 泡沫材料通过机器人技术施加在聚丙烯玻璃下壳表面上的基材上。 在泡沫材料固化后，将聚丙烯玻璃盖涂覆在泡沫材料形式上以产生气密的灰尘/水封。 盖子不粘附到固化的泡沫材料上，并且在需要维修时是可移除的。 泡沫材料也可以分配到模具中，然后转移到基底，允许泡沫材料的形状和轮廓的变化。 该方法也可用于在空气感应系统上产生隔离垫以吸收发动机冲击。 热乳液弹性体也可以用于在空气感应组件的盖颈和质量空气流量传感器之间产生密封。
