The two interested parts to be welded are a manifold with a flange, both in PA66 with glass fiber. A dedicated fixture is projected in order to exert a necessary pressure to hold in contact the two parts to weld: the manifold in absorbent material and the flange in transparent one. Only the weld area is heated with the result of an invisible joint, hermetically sealed, with no damage to other components or contiguous parts. An important advantage is given by the reduced costs, since you need a more simple workpiece. saving an c-ring and some screws, limiting the production stops due to screwing problems. |
