Application of the Flex Cracking Tester (Low Temperature) GT-KC11

1. Durable Construction

• Outer Chamber Material: Made of 2mm double-sided color-coated steel with a powder-coated surface for enhanced durability and aesthetics.
• Inner Chamber Material: Constructed with SUS304 stainless steel, seamlessly welded and reinforced with 10mm steel plates to meet the structural strength requirements of bending tests.

• Vacuum Glass Observation Window: Allows for effective monitoring of the testing process without compromising the chamber’s temperature.
• Temperature Control: Features a 7-inch color touch screen with Chinese and English language options for easy operation and precise temperature adjustments.

• Equipped with two sets of mechanical compressors and a two-stage compression refrigeration cycle, the GT-KC11 Whole Shoe Flexing Freezing Chamber ensures quick cooling to the specified internal temperature, even with multiple fixture groups.

• Separate Controller: Includes power-off memory and automatic stop functions when the test is completed.
• Corrosion-Resistant Fixtures: All testing fixtures are made of SUS304 stainless steel or aluminum, offering excellent corrosion resistance and anti-rust properties.

Step-by-Step Operation Guide

• Begin by opening the door of the Whole Shoe Flexing Freezing Chamber to prepare for specimen installation.

• Loosen the screw on the motor’s eccentric wheel.
• Move the eccentric wheel within the slot to adjust the travel distance. The farther from the center, the longer the stroke.
• Tighten the screw after setting the desired stroke.

• Adjust the grip travel so that the minimum separation between the grips is twice the thickness of Type A specimens or four times the thickness of Type B specimens (when clamped), plus an additional 2mm.
• The maximum separation should not exceed 20mm.

• Type A Specimens: Clamp the specimens in the grips with a 20mm clearance, ensuring no prestress or compression is applied.
• Type B Specimens: Fold the specimens with the side to be assessed facing outward, ensuring they measure 20mm x 40mm before clamping.

• After installing the specimens, securely close the chamber door to maintain the test environment.

• Temperature: Set the desired low temperature for the test.
• Test Cycles and Speed: Input the number of flexing cycles and the testing speed.

• Click the [START] button to initiate the test. The Whole Shoe Flexing Freezing Chamber will automatically stop once the set number of cycles is completed.

• Remove the specimens and inspect them for any signs of cracking or damage.

• 1. Regular Maintenance: Clean the Flexing Cracking Tester (Low Temperature) GT-KC11 and fixtures after each use to prevent contamination and ensure longevity.
• 2. Calibration: Periodically calibrate the temperature control system and flexing mechanism to maintain accuracy.
• 3. Proper Specimen Preparation: Ensure specimens are conditioned and prepared according to testing standards for reliable results.
