由于人们对保护自然资源的兴趣越来越大，以及与此相关的轻量化设计趋势，粘接在大多数工业部门中已成为一种越来越重要的连接技术。粘合剂粘合技术能够连接各种材料，有时是温度敏感的材料，从而实现多材料设计，从而实现轻质结构。同时，粘合剂有助于增加部件的刚性（Russo 2011年）。在工业实践中，不仅使用单组分粘合剂，而且使用双组分粘合剂，其固化过程在组分混合后开始。通常，两种粘合剂组分的自动输送、定量给料和混合由配料机进行。粘合剂粘合的质量可能会受到剂量过程的影响（Replike等人，2009年）。在该研究项目中，研究了冷固化双组分粘合剂的自动化处理的边界。因此，选择了工业相关的粘合剂加工技术和工艺参数。根据Gräter和Storz（2005年）和Stipp（2007年）的报告，这些技术和参数是不同的，并就其对连接过程和粘合接头的重要性进行了评估。
Adhesive bonding has become a more and more important joining technique in most branches of industries because of the increasing interest in protecting natural resources and the related trend towards lightweight design. The adhesive bonding technology enables the joining of various, sometimes temperature-sensitive materials, so that multi-material design and thereby, lightweight constructions can be realized. At the same time, the adhesive bonding helps to increase the rigidity of the component (Russo 2011). In industrial practice, not only single-component adhesives are used, but also two-component adhesives whose curing process starts once the components are mixed. In general, the automated conveying, dosing and mixing of the two adhesive components are performed by batchers. The quality of the adhesive bonding can be influenced by the dosing process (Fricke et al. 2009). Within the research project, the boundaries of automated processing of cold curing two-component adhesives were investigated. Therefore, industrially relevant adhesive processing technologies and process parameters were selected. These technologies and parameters were varied and evaluated with regard to their significance for the joining process and adhesive joint as reported by Gräter and Storz (2005) and Stipp (2007).
