APPLYING FLOWABLE MATERIALS TO SYNTHETIC SUBSTRATES

摘要

Methods and apparatuses are disclosed for applying activatable melt flowable materials to substrates made from synthetic materials. The methods are concerned with formation of appropriate flowable materials, control over the manner in which the flowable materials are applied, treatment of the substrates prior to application of the flowable materials and the selection of the optimum combination of materials for the substrates and the flowable materials. The methods may be particularly suited for applying flowable materials to surfaces to produce components found in automotive, aerospace including trucks, busses and tractors and marine vehicles.

1. A process for applying materials that are flowable when heated onto synthetic substrates comprising:
precisely applying a heat activatable flowable material onto one or more predetermined locations of one or more surfaces of synthetic substrates wherein the flowable material is extruded at a temperature that it bonds to the surface of the substrate and at a temperature below that at which it can be activated and then cools to provide a solid preferably dry to the touch material on the substrate ready for subsequent heat activation.
