DSTDP length out of tolerance
Problem Phenomenon
DSTDP product length deviation >±0.5mm, exceeding the tolerance
Cause Analysis
DSTDP shrinkage rate unstable, fluctuating ±0.5%; mold dimension design did not consider shrinkage compensation; cooling insufficient, dimensions not stabilized
Solution
1) Precisely measure DSTDP shrinkage rate and compensate the mold; 2) fully cool to ensure dimensional stability; 3) annealing treatment to eliminate post-shrinkage
Key Takeaway
Length out of tolerance is caused by unstable shrinkage rate; precise shrinkage compensation is key
