ABS draft angle 1.5-2°
Problem Phenomenon
ABS draft angle 1.5-2° minimum, increased for textured surfaces, demolding and deformation.
Cause Analysis
ABS draft angle 1.5-2° minimum for all vertical surfaces; increased for textured surfaces; smooth demolding; ejection deformation; surface quality; design specification.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Draft angle 1.5-2°; ②increase for textured surfaces; ③ejection system; ④deformation monitoring; ⑤design specification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
ABS draft angle is a design specification; textured surface compensation; ejection and surface both emphasized.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
