Since 1891, The Bonnot Company has designed and manufactured extrusion equipment. One of the unique features of a Bonnot extruder is a hollow screw which facilitates additional process temperature control through a re-circulating liquid.
Although the screw was pressure tested as part of a standardized ISO quality procedure, a leak of the liquid medium was discovered as it was installed at the end customer’s facility. The start-up of this product to the customer was critical, so the weld porosity needed to be sealed quickly.
