With this technique, an additional flexible profile, the “WSTplus profile” is used in a semi-closed cavity. This opens temporarily by means of a spray nozzle and closes again after applying the polyurethane.
Very narrow dimensional tolerances can be maintained – also at the rear – and additional functionalities, such as raised ribs and spacers, are immediately cast in polyurethane.
The “WSTplus profile” is brought into position and held by the upper mold half, which can also position all kinds of integrations with very high accuracy.
This technology is suitable for performing the same process during both the framing of a product and the gluing of various components on the same product with identical polyurethane material.
