Pinch-Off Weld Strength Tester for Blow Molded Bottles

Tester that evaluates strength of the pinch-off weld at the base of blow molded containers by tensile pull of a cut section. Used to detect weak welds that cause drop failures.

Specification

A section including the pinch-off is cut and pulled in a tensile fixture, or the base is loaded until split. Peak load and failure mode are recorded. Results guide blow pin and mold adjustments.
