In a blade bonding process, the adhesive is deposited on top of the stationary bottom shell that is resting at the lower mould, which is then exposed to a significant force by the approaching upper mould that is holding the corresponding counterpart. Metering and mixing systems for adhesives play a major role in the production of rotor blades. In the case of rotor blades that are more than 100 meters in length, up to 1200 kilograms of adhesive are needed to bond the two halves of the blades together. A plurality of spaced apart external access ports into the lumen are defined along the bond line. Let's explore exactly how these massive. In rotor blade production, one obvious way of accelerating the process would be to use polyurethane-based adhesives for rotor blade bonding, although these represent a very recent development in the wind power industry.
