What Are The Different Types Of Silicone Masking Plugs?

4 Jun, 2024 hitekadmin

Silicone masking plugs are a versatile tool for masking and can be used for processes such as powder coating and electroplating. The silicone’s temperature resistance allows it to be used effectively for masking and protecting surfaces underneath. However, there are many different types of masking plugs, which can make it difficult to know which one is right for your project. In this blog, we’ll take you through the different types of silicone masking plugs and their uses, so you can choose the best one for you.

Silicone Pull Plugs

These silicone masking plugs are great for blocking through holes, and their larger handle makes them easy to install and remove. They can withstand high temperatures and can be used more than once, making them an effective masking solution for manufacturers. The masking plug’s shape allows it to sit comfortably in a threaded or non-threaded through hole from powder coating to protect its inner surface.

Silicone Tapered Plugs

Tapered masking plugs are one of the most widely used masking plugs as their tapered design allows them to be used in many different scenarios. They’re most regularly used to seal blind holes and can fit in multiple hole sizes. Much like the pull plugs, silicone tapered plugs can be reused and offer a cost-effective option for filling in holes. These masking plugs can be used to protect surfaces in many finishing processes such as powder coating, plating, and wet painting.

Silicone Thread Plugs

Threading plugs are easy to install offer thread protection for blind holes. Their compact size allows them to easily mask off the thread of a blind hole during the powder coating process. The masking plug doesn’t interfere with any activities and reduces the shadowing effect, they fit tightly into the hole to keep the threads clean during the coating process.

Silicone Flangeless Plugs

Flangeless masking plugs have a ribbed design to make them more suited to threaded holes. Their unique design means that they can grip onto each section of the threads to make sure it is sealed tightly. The ridges in the silicone masking plugs minimise the risk of the plugs coming out during the masking process; however, they are still flexible enough to fit into different-sized spaces. These masking plugs’ handles also allows them to be removed easily after masking is finished.

Silicone Chamfer Pull Plugs

This type of masking plug can also be used for through holes. Pull plugs are made of softer rubber, so they can seal spaces tightly and are most used for masking off leading threads, countersinks, and chamfers. The silicone masking plugs can be used for both low and high temperature processes, like powder coating. The pull tab of the pub allows for easy removal of the masking plug, but it’s important to keep in mind that this will be exposed after the plug is inserted.
