The result is the aluminum is difficult to push through the die at the beginning of the cycle and the extrusion speed must be reduced at the back of the billet to prevent defects.───其结果是，在挤压周期开始时铝锭难以被挤压通过模具，铝锭后部的挤压速度必须被降低，以防止挤压出废品。
The Tee Seal USES two Nylon Back-Up Rings as anti-extrusion devices, allowing the Tee Seal to function under much higher pressures than a standard O-Ring.───在发球密封采用两个尼龙备份，作为抗挤压设备的戒指，让T恤印高得多的压力下功能比标准O形圈。
Being broken by feeding materials into hammer mouth, extrusion between crushing, finished materials back down naturally.───被破碎物料经给料口落入锤头之间，进行挤压反击破碎，成品物料自然落下。
Kuyto heights should also be size to fit form, are not excessive pushing back so as not to back extrusion;───托板高度也应调至合适状态，不可过度顶压书背，以免书背挤压变形；
