Metering technology for the production of household appliances
Solutions for all production steps: bonding, sealing, greasing, potting and gasketing
The production of modern household appliances for the global market requires stable, automated production processes. This is essential for long-term success in the competitive international market.
Metering and mixing technology is a key part of almost all production steps in the household appliance industry. The various components are bonded, sealed, greased or potted during the production process. DOPAG offers the customised metering and mixing systems required for every type of application: bonding, sealing, greasing, oiling, potting and gasketing.
For sealing, DOPAG offers metering systems for the dynamic mixing and application of sealing foams as well as metering and mixing systems for the application of adhesives. Various systems fitted with piston or gear pumps are available for the metering, mixing and application of sealants and adhesives. For greasing and oiling, a modular range of metering components, valves and pumps enables individual systems to be set up, which can be integrated into automated production lines.
We adapt and customise all metering and mixing systems to your specific requirements. Our engineers and technicians support you throughout the design and execution of your production processes.

Rinsing
- Gasketing: foamed seal on installation side
We offer metering and mixing technology for these applications:
Gasketing
Gasketing
Provides external sealing of housing and protects electronics from dust and moisture.
Bonding and sealing
Bonding and sealing
Components are bonded and sealed against dust and moisture.
Potting
Potting
Electrical and electronic components are potted with epoxy resin, for example, and thus protected against dust, moisture, corrosion and shock, as well as providing sight protection and protection against replication.
Greasing and oiling
Greasing and oiling
Moving parts or seals are greased, which ensures a long functional life.

Custom-built dispensing systems to automated bonding applications
Automated component handling as well as integration of pre-treatment and post-treatment
We cover every step involved in the automated application of adhesives:
- Pre-treatment: plasma, corona flame, brushes
- Adhesive application for one, two and multi-component adhesives and sealants
- Different application methods: bead, spray, thin layer
- Manual, semi-automated or fully automated systems depending on level of automation
- Joining techniques: hot stamping, clinching, screwing
- Hardening systems: infrared, ultraviolet (UV), medium-frequency technology, continuous furnaces
- Various robot systems
- Quality assurance: volumetric measuring systems, verification of adhesive application (position and quality), component control and measuring
- Process data archiving, process visualization: data carriers (USB, flashcard), network, SCADA systems
Bonding and sealing is becoming an increasingly popular method of joining components without screws. With DOPAG systems, applications can be realized reliable and precise.
With dynamicLine and the new dynamic mixing head, DOPAG offers an efficient solution for all applications relating to gasketing.

Dynamic mixing head
Dynamic mixing headThe dynamic mixing head with its new valve technology has been designed for mixing of low to high-viscosity polymeric reaction substances for foaming, bonding, sealing, and potting.
In Potting, resins such as silicones, polyurethanes or epoxy resins are used in liquid form. For the production process, DOPAG offers various metering and mixing systems.
Whether it be racks, headrests, door locks or just the wheel bearings in automobiles, all must be greased. DOPAG provides the optimum metering system for each of these applications.
