Tolerance Stacking and Its Impact on Assembly Accuracy

Dalian Zhongsheng Metal Products Tolerance Stacking and Its Impact on Assembly Accuracy

Tolerance stacking occurs when dimensional variation accumulates across multiple features or parts. Even when individual tolerances are met, stack-up can cause misalignment, interference, and assembly failure. Controlling tolerance stacking requires proper datum selection, functional dimensioning, and manufacturing capability alignment.

ASTM Standard and Its Role in Manufacturing Compliance

Dalian Zhongsheng Metal Products ASTM Standard and Its Role in Manufacturing Compliance

An ASTM standard establishes consensus requirements for material composition, mechanical properties, test methods, and acceptance criteria. In manufacturing, correct use of ASTM standards supports material selection, supplier qualification, inspection consistency, and compliance control, but does not replace application-specific requirements.

Sheet Metal Notching and Its Impact on Assembly Accuracy

Dalian Zhongsheng Metal Products Sheet Metal Notching and Its Impact on Assembly Accuracy

Sheet metal notching plays a critical role in assembly accuracy. Poor notch geometry alters material flow during bending, causing tolerance deviation, cracking, and misalignment. Understanding sheet metal notching behavior helps reduce rework and control forming quality.
