Flat Shape Bottles

Bottle Dimension Measurement：High-precision calipers verify height, diameter, and other parameters, ensuring perfect alignment with design specs.

Bottle Weight Inspection：Electronic scales control weight consistency across batches for standardized production.

Volume Accuracy Testing：Professional equipment measures actual capacity to match labeled volume precisely.

Print Adhesion Test：Evaluates the bonding strength of prints (labels, patterns, etc.) to prevent detachment or fading.

Cutting Resistance Test：A tool simulates scratching to test the adhesion and wear resistance of surface treatments (e.g., spray coatings).

Internal Pressure Testing：Specialized instruments apply internal pressure to test the bottle's pressure resistance and safety under extreme conditions.

Vertical Axis Deviation Test：Checks vertical alignment to avoid cosmetic defects and tilting during filling.

Impact Resistance Assessment：Simulates collisions and drops to test the bottle's durability in transit and use.

Leak-Proof Detection：Sealed bottles undergo leak testing to ensure zero leakage during storage and transportation.
