The objective of this work is to evaluate the introduction of bonding technology in the assembly of beverage filling machines. In this specific field, bonding has two potential great advantages with respect to welding, that are the speed of application and the absence of thermal distortions. Furthermore, since it presents fewer risks for safety at work, it allows the simultaneous execution of other assembly operations. On the other hand, the use of bonding requires a design process integrated by tests related to the specific application and operating conditions, that in the case of food machinery are: i) bonding of low surface roughness, austenitic stainless steel without surface preparation but degreasing; ii) contact of the joint with the chemically aggressive substances used for cleaning and sanitization. In the present study, first a technical-economical comparison with welding (business case) was done on a component of the structure of a filling machine. Then the adhesive appropriate for the application was identified experimentally with tests on single-lap joints (SLJ) with different surface finishes and subjected to chemical aging under the cleaning and sanitization agents. Finally, the scale-up to a larger and more complex structure was performed by joining two modules of the outer casing of a filling machine.

这项工作的目的是评估饮料灌装机组装中粘合技术的引入。在这个特定的领域中，粘接相对于焊接具有两个潜在的巨大优势，即应用速度和无热变形。此外，由于它带来的工作安全风险较小，因此它允许同时执行其他组装操作。另一方面，粘接的使用需要通过与特定应用和操作条件相关的测试来整合设计流程，在食品机械的情况下：i）粘接低表面粗糙度的奥氏体不锈钢，无需进行表面处理但可以脱脂; ii）关节与用于清洁和消毒的化学侵蚀性物质接触。在目前的研究中，首先，对灌装机结构的一部分进行了焊接的技术经济比较（业务案例）。然后，通过在具有不同表面光洁度的单膝关节（SLJ）上进行测试，并在清洁和消毒剂的作用下进行化学老化，通过实验确定了适合该应用的胶粘剂。最后，通过连接灌装机外壳的两个模块，可以放大到更大，更复杂的结构。
