Adhesive bonding is the process of joining two work pieces securely by using a liquid or semi-liquid material to create a long-lasting bond. In a high-volume manufacturing environment, adhesive is usually applied using specialized application equipment. Adhesives can be dispensed in a continuous bead or as dots using automation equipment and manual hose-fed handgun system. Virtually every product assembled requires bonding or sealing at some stage of the process. Graco offers manual and automated technologies for single-component and two-component bonding and sealing for a broad array of products, markets and end-uses.
