摘要 |
the workpiece consists of a profiled metal core (2.2) with plastic coatings (2.1,2.3) on both sides. The plastic coatings are stuck onto the core in a mould of appropriate upper and lower shapes during the application of thermal energy and pressure. The profiled metal core is electrically heated to a predefined process temp. by a regulated current. The resulting heat melts the adhesive between the metal core and the plastic coatings. |
