Leister Tutorial | Easily check a welding seam for leaks

With our VACUUM BOX and PUMP you can easily check to see if there are any leaks in a weld made by an Extrusion welder. Vacuum box testing is a non-destructive examination used when trying to locate weld seam leaks. A vacuum box and a compressor create a vacuum while a detergent solution is applied to the test area. The detergent bubbles, make leaks visible within the created pressure zone. https://www.leister.com/en-ch/plastic...
