Lord Corp.’s (Cary, N.C.) newly developed cost-modeling software program for structural bonding is designed to assess cost reductions achievable through the use of structural adhesives in place of fasteners and welding. The software is a product of Lord’s experience in the use of adhesives in transportation industries: The model parameters are based on actual time studies and accepted industry norms, but most can be adjusted to match specific customer situations. For example, the model estimates the time to perform certain welding and fastening tasks, but the user can override these estimates if more relevant data is available. Ultimately, the software produces a report that summarizes the analysis and results and indicates whether a switch to adhesives would improve cycle times or provide a cost reduction.
