4 Common Challenges in Precision Masking

Technological or professional medical equipment using plated metal parts that has been precision masked.

Precision masking is a careful process – a lot of attention needs to be given to finer details to avoid making mistakes. These challenges can cause a waste of specialised masking products used in permanent masking methods or the object that needs to be protected.

But what are the common challenges people face when metal masking? Keep reading our blog to learn about the four main challenges that occur during the precision masking process and how to avoid them.

1.    Plugs Falling Off

Holes and threaded areas intended for screws or bolts are generally blocked with pull plugs like silicone tapered plugs. They’re specially designed to insert securely to protect the area during metal plating or painting. More specifically shaped or sized products that require permanent precision masking may require self-threading plugs.

If you find that these silicone and rubber plug options are falling off or out of the required area during the precision masking process, they may not be the right option – lacquers are a great temporary solution. If you have the budget then we would recommend a custom permanent precision masking solution, just get in touch with our team and we can discuss the best options available for your project.

2.  Masking Peels Off

You must ensure that the surface of the object, before applying the masking product, has been pre-treated properly. You also need to make sure that the method you have decided to use for metal plating, painting or anodizing is compatible with the material of the object. If you haven’t correctly treated the surface of your object, then this will quickly become apparent when your precision masking starts to peel off.

3.  Masking Unable to Handle Temperature

The most common masking mistakes made is choosing precision masking methods that are incompatible with the high temperatures that are reached during the metal plating or anodizing processes.

It’s important to have an understanding of the maximum temperature of your bath and the limits of the precision masking options available, so that you can make a better decision with a more heat-resistant precision masking or permanent masking method – for example, our range of high-temperature masking tapes can withstand temperatures between -54° to 220° Celsius.

4.  Accidental Masking

There are a couple of different issues that can cause accidental masking.

  • It’s called precision masking for a reason – make sure you take your time and pay close attention to where you’re masking otherwise the masking may get somewhere that you don’t want it to be. You should be extra precise with liquid masking products.
  • Ensure your workspace is clean and tidy – a cluttered space can lead to unnecessary obstacles or distractions when precision masking, or not enough attention being paid to finer details.
