The PLS Production Line Simulator allows to simulate in a reproducible and accelerated way the friction on a packaging line.

The testing process simulates the abrasions associated with contacts between bottles, typical of packaging lines.

It is the ideal device for determining the build quality of glass bottles as well as their coatings, decorations and labelling.

Applications :

• Simulation of the packaging line for bottles and cans
• Evaluation of the quality of the coating of the bottles
• Evaluation of wear and abrasion of bottle labels
• Assessment of abrasion on returnable bottles

Characteristics:

• Easy operation, use in laboratory
• Adjustable cycle time and speed
• Adjustable conveyor border spacing from 50 to 150 mm
• Stainless steel construction
• Adjustable and swiveling water nozzle

The TWB-1 Thermostatic Water Bath is a thermostatic water bath equipment that developed by AT2E. It is use to perform the thermostatic tests for products in various field, so that to provide reliable data for estimating the product quality.

For testing the Stress Crack Resistance of Carbonated Soft Drink Bottles. The AT2E SCT-D Stress Crack Tester is designed to test the internal stress in bottle base and for determining the stress crack resistance of blow-molded PET carbonated soft drink bottles by measuring the propensity for base cracking upon exposure to an aqueous sodium hydroxide solution under a controlled environment, so that to estimate the long term behavior of bottles. As per the above screen shot, during the test, the bottles in #6 and #16 positions leak, the lights of positions #6 and #16 will become green automatically and system will stop pressurizing the corresponding positions. Or, operator can press the position button to stop pressurizing if any tiny leakage occurs by observation. Leak pressure value and time will be displayed below the button. System will also generate a data table for each test to record the test pressure of each position. In the table, position with green light will be displayed as “NG” with the leakage pressure value. Normal position will be displayed as “OK” with the predefined pressure value. The data table can also be printed out through the mini printer.
Attributes:

• Multi-position design, more convenient and efficient (Please consult AT2E for other position request).
• Automation control ensures the high accuracy and repeatability.
• High quality stainless steel frame which is safe and durable.
• Superior controlling components ensures the accuracy and durability.
• Flexible position selection – each position can be controlled separately by system. Users can enable the positions (from 1 to 26) according to their test request.
• Automatic pressure compensation during the test process.
• Suitable for testing various size of bottle.
• Corrosion-resistant design
• Anti-explosion and clear observation window which is safe and easy to observe the sample status during a test.
• Various safety designs.

For test of internal stress in bottle base.

The AT2E Stress Crack Tester is designed to test the internal stress in bottle base and for determining the stress crack resistance of blow-molded PET carbonated soft drink bottles by measuring the propensity for base cracking upon exposure to an aqueous sodium hydroxide solution under a controlled environment, so that to estimate the long term behavior of bottles.

Testing procedure:

• Install and clamp the sample bottle on each position then close the door
• Affusion head will seal and fill the bottle automatically with target volume of water then pressurize the bottle to predefined pressure and stay for a target time (like 5 minutes). At same time of water filling and pressurizing, system will fill the solution into each position
• After target staying time is up, all the testing positions descend until the predefined distance and bottle base will be covered by the solution completely
• Record the time and pressure for each bottle to failure until predefined time
• Test stops after the predefined time

Attributes:

• Muilt-position design, more convenient and efficient (Please consult AT2E for other position request)
• PLC control ensures the high accuracy and reliability
• High quality stainless steel frame, more safe and durable
• Flexible position selection, each position can be controlled separately by system. Users can enable the positions according to their test request
• Automatic affusion system
• Auto pressure compensation during test process
• Suitable for testing various bottle size
