- 这是由于为热膨胀效应而设置允差以及在锻模上需要拔模斜角所致。
These results from the allowances made for thermal expansion effects and the need for draft angles on the forging tools. - 拉拔模的弹性变形是影响拉拔精度的重要因素,但往往在拉拔成形中被忽略。
The elastic deformation of drawing die is an important factor which can affect the accuracy, but it is often neglected in draw forming. - 硅模具有能力再创造更重要的细节,因为硅、拔模角度、嵌入插件和咬边对柔韧性的要求不如其他模具过程那么高。
Silicone molds are capable of reproducing remarkable detail, and because of the flexibility of silicone, draft angles, inserts, and undercuts are not as critical as in other molding processes.
