机头发泡口模温度对发泡体结构和性能有关键性影响。
Die temperature has great effects on the cell structure and foam properties.
有时，较低的口模温度会在口模内表面上生成一个冷却的树脂层，这个树脂层慢慢地移出到口模出口，然后与本体料流分离，从而引起积料。
Sometimes lower die temperatures can create a cool layer of resin on the inner surface of the die that creeps slowly to the die exit and then separates from the bulk flow, causing buildup.
从确定真正的熔体温度开始，然后按照这个温度设定口模体的温度。
Start by determining the true melt temperature and set the die body to that temperature.
