Cartridge heaters can be placed through drilled holes in order to heat up metal parts, which can be handy in a variety of industrial applications. However, even though these heaters are fairly easy to use and are highly useful, they can be a pain to insert in drilled holes. Luckily, there are a few steps that you can take that will make insertion easier. Try these three tips to make the use of your cartridge heaters a whole lot easier.
Create Looser Drilled Holes
Even though it is true that a tighter fit can help you maintain better heating with your cartridge heater, smaller drill holes can make it much more difficult for you to insert or remove your cartridge heaters. Because of this, it can be smart to consider using a slightly larger drill bit to make the drill holes a little bit larger. You'll want to look for a balance, so that the holes are large enough for the heater to fit into them, but tight enough that they will still hold the heat in. Consider experimenting and slowly making each hole just a little bit larger until you have the right fit. After all, you can use your drill bit to make the holes a bit bigger, but you can't easily make them smaller after they have already been drilled.
Make Sure Holes are Drilled Completely Through
If your drill holes are not drilled completely through the part, it is going to be more difficult to insert the cartridge heater. This means that you should take the time to ensure that they are drilled all the way through for best results. The top of the cartridge heater is larger than the heating element that is inserted through the hole, so you should not have to worry about the heater falling through.
Using an industrial lubricant will help make the cartridge heater fit more easily into your drilled holes. Keep a lubricant close at hand, and if you find that your heater is getting stuck while you are attempting to insert it, add a small amount of lubricant to the heater to help. Just make sure that you only use a little bit at a time, since using too much can make a big mess and can affect the metal parts.
As you can see, there are a few tips that you can follow to make your cartridge heater fit into your drilled holes on your metal parts more easily. If you give these simple tips a try, you are sure to find that the heater insertion isn't as much of a pain as it may have been in the past.
