What problems may occur in the manufacturing process for products with extremely small cross-sections?

1. The processing of mold cavities is very difficult, and it is generally difficult to achieve complete consistency between the product features and the drawings
2. The precision requirements for molds are high, and the machining errors of the inner diameter and cross-sectional cavity size of the mold must be controlled within a very small range, otherwise it will cause the size of the O-ring to not meet the standards and cannot be used normally
3. The number of element points collected during measurement is relatively small, so the measurement error will be relatively large
4. Difficult demolding and easy to damage the product
