SAFQ Snap Tester Clamps Improved

Release Date 06.26.12Subscribe RSS

SDL Atlas is pleased to announce that the Upper Snap Clamp and Lower Fabric Clamp for the SAFQ Snap Tester have been redesigned to enhance the use of the Snap Tester. The aim of the redesign was to address customers’ desires for a more secure and more user friendly testing experience.

The SAFQ Snap Tester, designed and patented by YKK to determine the holding or breaking strength of prong-ring attached snap fasteners onto garments, has become a standard for safety testing in children and infant garments. Nike, GAP, Levi and H&M specifically adopted the tester throughout their supply chains.

SDL Atlas has made five major enhancements to the clamps including two improvements to the Upper Snap Clamp and three improvements to the Lower Snap Clamp.

The Upper Snap Clamp has an improved simple locking mechanism that, unlike the former screw type locking mechanism, requires minimal force to properly set the sample. Engagement is now just a simple push of a toggle hinge which helps ensure that the vertical alignment can be easily maintained. In addition, the new toggle hinge completely swings away from mechanism allowing the jaws to open and close freely highly reducing the sample loading and unloading times.

Additionally, in order to provide more precise testing, three individual Upper Snap Clamps have been designed to cover the same range that the previous single Upper Snap Clamp covered. The former Upper Snap Clamp was designed to test a snap or button from Linge 12 to Linge 30. The new design features a low range clamp for Linge 12 to Linge 16, a medium range clamp to test from Linge 16 to Linge 21 and a high range clamp to test from Linge 21 to Linge 30. Needless to say, reducing the applicable range can help to ensure a better fit of the jaw curvature onto the test specimen, thus providing a more secure clamping action.

The Lower Fabric Clamp has also received a number of improvements. The Clamp Plate has been modified to now have a rubber ring at the clamping edge to help prevent any damage to the sample during testing. The Supporting Die on the Lower Fabric Clamp has also been modified. The modified die replaces the former concave metal washers with more flexible hard rubber washers which help to eliminate distortions to the fabric that may have occurred with the previous die. This ensures that the clamping force can be guaranteed regardless of the sample thickness. The Lower Fabric Clamp also features a modified locking mechanism where a bearing now replaces the direct contact to the cam wheel, virtually eliminating wear and ensuring smother operation.

These modified clamps are all compatible with existing SAFQ Snap Testers and are endorsed and patented by YKK. SDL Atlas is the exclusive supplier of the SAFQ Snap Tester.
