Dispensing of adhesives and sealants
Dispensing systems for the production of white goods
Household appliances such as dishwashers, ovens and washing machines make work much easier in many respects. Our solutions for the processing of adhesives and sealants enable innovative appliance designs. The trend shows that the users, apart from making high demands on the functionality, are demanding higher and higher standards as regards appliance design. To meet this challenge, the manufacturers of household appliances are focusing even more on innovative production technologies and new material combinations. Especially in the field of joining technology with its high demands on process stability and product quality, manual procedures are increasingly being replaced by fully or partially automated processes. DOPAG metering and mixing systems apply adhesives and sealant with maximum precision and guarantee the optimum result for products of the appliance industry.
Intelligent solutions by DOPAG
DOPAG stands for expertise in the fields of bonding and sealing. This expertise ranges from maintaining the optimum mixing ratio to high flow rates when discharging the adhesive and to accurate shape and position of the application. The result is an optimum fit and distortion-free manufacturing. As additional benefits, conservation of resources and a good waste balance are offered, with low waste disposal costs as the materials are joined not earlier than in the mixing tube. In addition, DOPAG systems are operated without flushing agent and thus protect the environment. The materials to be processed are mainly silicones that withstand the often high ambient temperatures without difficulty. Another decisive benefit is DOPAG's service profile as regards the automatic application of the adhesive since, in the production of household appliances, automated manufacturing is the standard practice.
