选与凹模孔径匹配的金属半圆冲（dapping punch），将退火圆片放入对应凹坑，冲头对准中心，用木槌或软面槌垂直敲击冲尾数次，使片材贴合模腔成半球。紫铜片厚 0.5–1.0 mm 为宜；过厚难成形，过薄易起皱。每打几槌检查贴合度。
Pick a dapping punch matching the block bore, seat the annealed disc in the matching cavity, centre the punch and strike its tail vertically a few times with a mallet so the sheet conforms to the hemisphere. Copper 0.5–1.0 mm works best; too thick won't form, too thin wrinkles. Check fit every few blows. ---
