6.Draft analysis (Cavity) 前模侧脱模分析拔模前
Before Draft
Draft 3° Material
decrease by 0.02mm
for each side
拔模后
After Draft
Draft 1° Material
decrease by 0.075mm for
each side
Draft 1° Material decrease by 0.13mm
for each side, measure based on the root of
the part.
Draft 1° Material
decrease by 0.06mm for
each side
绿色面无拔模斜度
No draft angle on green surface
Draft 1.5° Material decrease by 0.16mm
for each side, both side of the product need
be shut-off structure
