Constructive Bonding of Oven Doors

Mounting metal sub-constructions to oven doors is oftentimes done with liquid glues (or other conventional fastening methods) – this is an inefficient concept that can be improved by using double-sided tapes. To be more precise, acrylic core tapes are the right solution for this application, leading not only to an improvement in production time but also to an increase in overall efficiency. Today’s kitchen appliances come in a sleek, state-of-the-art look – ideally without any visible fastening methods. An application like this illustrates a perfect example of the possibility to work with preassembled parts that come with the tape (or die cuts) already applied to them – in short, pressure-sensitive adhesive tapes make the process cleaner and more measurable.

What Else Makes This Application a Hot Topic for Adhesive Tape Technology?

If the question is whether the required tape must be able to withstand elevated temperatures – one could ask whether a pressure-sensitive adhesive tape can even handle these kinds of temperature environments – the answer is clear: tesa® ACXplus can. Our ACXplus product family combines innovative technologies with the ultimate goal of providing a high-quality product that is able to handle all the requirements needed for your application, even when we are talking about temperatures up to 200 °C (approx. 400 °F) directly at the bond.

tesa® ACXplus 707x High Resistance Is the Answer.

This series is our number one recommendation for this application. Our High Resistance series is characterized by a foamed acrylic core and a pure acrylic adhesive layer. Its high-performance acrylic system features a unique formulation, which results in excellent temperature resistance and outstanding cold shock performance (down to -40 °C). One key characteristic that comes into play in demanding oven door applications is the viscoelastic acrylic core, which is able to compensate for thermal elongation of bonded parts. Especially when mounting dissimilar materials, this property plays a crucial role.

Advantages of tesa® ACXplus over liquid glues for this type of application, which underline an improvement in overall efficiency:

  • No set-up time or cleaning of machinery equipment required
  • Reduction of complexity while increasing flexibility
  • Easier and cleaner handling
  • Fast application process by eliminating curing time

What key characteristics come into play in oven door bonding?

  • tesa’s viscoelastic acrylic core can withstand thermal elongation
  • High adhesion to a broad variety of substrates
  • Dampening properties
  • Deep black color for design reasons
