The SSA-PLC-12 Secure Seal Analyzer (12 Positions) is a special instrument developed by AT2E for control of the secure seal performance of caps on preforms.

Attributes:

• Muilt-position design, more convenient and efficient.
• PLC control ensures the high accuracy and reliability.
• Stainless steel frame, more safe and durable.
• Flexible position selection, each position can be controlled separately by system, users can choose to enable the positions (from 1 to 12) according to their needs.
• Linear pressurizing, able to set up to 4 pressurization steps, and hold the pressure according to the predefined period.
• Auto pressure compensation during test process
• Special designed clamping device, enhanced the sealing performance of test.
• Anti-explosion and clear observation window, safe and easy to observe the sample status during tests.

PET Preform Stress Viewer.

Many of the defects found in PET container preforms can be detected by using the PL-P. Preforms viewed in polarized light exhibit a colored birefringence pattern. The birefringence is a result of the polymer flow lines (molecular orientational strain) produced during the injection moulding process.The colored pattern observed with preform held at 45° to the polarizing axis is known as an isochromatic fringe indicating the amount of birefringence. When the preform is held parallel to the polarizing axis a black isoclinic can be seen indicating the direction of the molecular orientational strain. By correctly interpreting these flow patterns many preform defects can be detected.

With angle adjusting design, operator can view the preform as their most convenience angle. And the upgraded wider viewing area and sample platform, more preforms could be placed and viewed in the same time. It also frees the hands of operator.

Allows to cut easily the bottles neck in order to prepare the bubble test with adapted cap holder or to measure some accurate points on a preform.

Easy operation.

Cutting range ( diameter ) :0 to 42 mm / other on request

PTG Preform Thickness Gauge is used to measure the preform thickness.

It’s easy to operate and applicable for various sizes of preform (various supports for different sizes of preform).

The PPG-D Preform Perpendicularity Gauge is used to measure the perpendicularity (deviation) of the preform, it’s a standard equipment for PET and beverage industries.

With the high accuracy three jaws chuck, it can ensure the accurate measurement of different sizes of preform.

The PPS-1 Preform Profile Saw is suitable for cutting different kinds of preforms for quality control of material distribution, especially for multi-layer preforms. The total mechanical design and electricity free, more compatible and adaptable to various working environments

Features:

• Easy operation, cut by the ratchet wrench
• Exclusive spacers to ensure the smooth cutting surface
• Blade holder design, prevent the holder from slipping accidentally

Optional parts:

• Exclusive spacers according to preform size
