ABS shrinkage rate 0.4-0.7
Problem Phenomenon
ABS shrinkage rate 0.4-0.7% uniform amorphous, dimensional accuracy advantage, mold design.
Cause Analysis
ABS shrinkage rate 0.4-0.7%; amorphous material uniform and predictable in all directions; high-precision dimensional tolerances; complex geometry; mold design compensation; process stability.
Solution
①Mold designed according to 0.4-0.7%; ②utilize uniform shrinkage; ③process stability; ④actual measurement verification; ⑤tolerance management.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
ABS low uniform shrinkage is a dimensional accuracy advantage; mold design is precise; verification ensures accuracy.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
