ADHESION TECHNOLOGIES LTD.: Fastening System
This company recently launched its new Spida™ fixing and fastening system. The fixing technology has reportedly been specifically developed to offer OEMs and Tier 1 companies a fast, cost effective system for the modular assembly of composite, metal, and plastic parts using metallic and non-metallic fixings.
The fixings use a proprietary adhesion system that forms a high strength bond with a range of substrates. Spida bases have a number of key design features incorporated to improved adhesive performance. All base option designs reportedly include a large bearing area for attachments and a positive landing area which prevents adhesive from being squeezed out from under the fixing, as well as concave shape that provides a micro chamber in which an adhesive’s long chain molecule structure can orientate from 0-180° during curing, resulting in better peel, shear, torsion, cleavage, tension and compressive loading capabilities. Each base also uses a surface enhancement treatment technology on the bond interface. The overall result is a stronger, lighter, higher performance method of mechanically joining metal, composite, and engineering plastic components, which provides up to 54% more adhesion performance, according to test data. The Grippa base fixing option, with its castellated edge design, can provide 24% greater torsional resistance strength than circular fixings by forming lugs in adhesive.
