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.

Household appliances

Greasing, gasketing, bonding, sealing and potting for:

  • Coffee machines, toasters
  • Kneading devices, mixers
  • Microwaves
  • Vacuum cleaners
  • Air conditioning systems
  • Steam irons


  • Gasketing: foamed seal on installation side

We offer metering and mixing technology for these applications:



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.



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.
