During Applied Felts’ multi-stage production process, we continually test a number of criteria including density, thickness, fiber distribution evenness, strength and weld-ability of the finished product. Once the liner has been constructed, the material is then coated, using a “single pass” extruded process to ensure there are no pinholes present. During this phase, tests are again conducted to monitor coating uniformity, mass and weight distribution.
Continually checked throughout the process to ensure the product satisfies the specification of your order, the finished liner is then sampled and destructively tested across a variety of quality characteristics, including density at various pressures, tensile strength, coating distribution and more. Finally, samples are cut and tested across several additional criteria to make sure the circumference, density, length, coating integrity, weld strengths and other properties have not been compromised.
