Bonding instead of drilling


Might not sound like a logical dilemma but bear with me.

Let’s say you’re manufacturing something out of metal. To make sure this metal stays rust-free and protected from different external influences, it’s most likely going to be mechanically and chemically treated, before it’s finally painted with either powder or liquid paints – for protection and aesthetic reasons.

Out of such metal parts, you may manufacture different things: washing machines, fridges, coat hangers, or like in our video – electrical cabinets.

In many cases, like in the video example, you may need to attach something to the metal parts and that something can be made of different materials. Composite materials and plastics are two of the most common materials that turn up in many industries, although it can also be another metal or the same type of metal as the original parts.

The usual method to do this is to drill holes in the metal part and attach other materials using bolts. The problem with drilling is that it’s loud and messy, leaving behind the debris that needs to be cleaned up, which makes it very time consuming, too.

When we’re talking about electrical cabinets specifically, the metal debris is a double problem – the already mentioned mess it makes is one thing, but even more importantly, tiny metal pieces can easily stay behind somewhere, escaping the cleaning and later on cause short circuits (being metal and electrically conductive) and with that various malfunctions. And that’s certainly not something you want on electrical equipment, both: from functionality and safety aspect.

Additionally, with every hole you drill, you’re risking paint damage around the drilling point and with each and every drilling point you are creating a potential starting point for rust.

Alternatively, you can choose to bond your parts. Loctite HY 4070 or Loctite HY 4090 do (depending on the application requirements) the trick with just a few drops. They are applied quickly, no clean-up is necessary afterwards and already within maximum 2 – 6 minutes (less if there’s no gap filling between the parts) they will fixture and you can proceed with your manufacturing process.

Have a look at the video to see the two methods compared.
