Tool wrapping successfully replaces working with tools in a controlled environment like that of a special furnace, which is laborious and very costly. It provides a highly efficient surface protection, but only when employed as it’s meant to. When using stainless steel tool wrap, you will be happy to have minimized losses and made the most of your investment. Here are 5 tips to guarantee your success:
- Choose your steel grade and temperature rating correctly
It’s important to check what grade of steel wraps you are dealing with and how much heat they can handle. Otherwise, you risk damaging the foil and compromising your work if the applied temperature is too high. See what the distributor says about the type of steel and the range of applications you can use it with.
- Create an airtight package
You need to wrap the part to be heated like in an airtight envelope. To draw out as much air as possible, you may carefully manipulate it to eliminate air. Watch out for any tears or holes. To avoid this and eliminate the oxygen inside, it’s best to place a burning ember inside this envelope – it will consume more of the oxygen that’s left, thus creating a more suitable atmosphere.
- Create a vent
This may be counter-intuitive, but it’s a necessary measure in order to prevent foil tearing. When heated, the air inside the package dilates and can damage the wrap. The vent must be no bigger than 5 mm.
- How to handle components with sharp edges
Sharp edged components will give you more trouble. To form a reliable wrap, you should be using two foils. This double wrapping ensures the parts harden as needed, but you may also need to increase the temperature.
- When to choose tool wrap steel
Tool steel wrapping is suitable to many industries and countless applications. However, when you have steel that hardens in water or oil, you should consider other options. Steel tool wraps are usually recommended for air hardening.
Always use foil made to resist the heating temperatures you’ll be using. Otherwise, it will be damaged. Nickel based allows work best with the highest of temperatures.
