Appliances like washing machines, stoves, and dishwashers are manufactured in large numbers and are generally subject to a short product lifecycle. On the other hand, there are high requirements for joined materials with long-term stability as well as cost-efficient processes. This has been reflected in increasing attention to adhesive bonding within the manufacturing process, with the aim of achieving simple and cost-effective durable joining of materials. Beyond that, the long-term stability of imprinting is important, especially given the wear on appliances caused by moisture and alkalis.

Openair® Plasma pre-treatment can be automated using robots and easily implemented in the manufacturing process. Once it has been integrated, this system delivers reliably monitored and reproducible surface pre-treatment with the push of a button.

Plasmatreat is constantly developing new, unique Openair® Plasma applications in successful partnerships with major international manufacturers in the appliance industry.

Advantages of pre-treating appliances with Openair® Plasma:

  • Material costs reduced with the option of using alternative materials, such as polypropylene (PP)
  • Manufacturing costs reduced by avoiding chemical bonding agents (no primer required) and economizing on manual production steps
  • Quality improved by precise, selective activation

High-gloss polypropylene pretreatment before printing

Since 1999, the polypropylene handles of hand-held blenders have been pretreated with atmospheric plasma systems from Plasmatreat before pad printing at the BSH plant in Slovenia. This process ensures a flawless print image on high-gloss plastic that would otherwise make printing difficult.
