The development direction of anti-theft bottle caps
2.1. Compression-molded cover replaces injection-molded cover
Although compression molding is a new process that has only appeared in the past 10 years, it has a strong impact on the century-old traditional injection molding process.
Challenged by force, and achieved an overwhelming advantage. At present, compression-molded lids account for Coca-Cola, Pepsi, Uni-President, and Master Kong.

The number of compression molding equipment purchased greatly exceeds that of injection molding equipment.
⑻. Leakage (air leakage) angle: draw a straight line between the bottle cap and the bottle mouth support ring for the packaged sample. counterclockwise
The needle slowly rotates the bottle cap until an air or liquid leak occurs, and then stops immediately. Measure the angle between the marking line on the cap and the support ring
Spend. (The national standard requires safe opening performance. The original standard required less than 120°. Now it is changed to the bottle cap not flying when it is fully unscrewed.
off)
⑼. Broken ring angle: draw a straight line between the bottle cap and the bottle mouth support ring for the packaged sample. counterclockwise slowly
Rotate the bottle cap and stop immediately after observing that the anti-theft ring of the bottle cap is broken. Measure the angle between the marking line on the cap and the support ring
Spend.
