How to Cut Silicon – Tips, Advice and How to Guide

In this how to cut silicone guide we will walk you through all the info needed to safely and easily cut silicone. We will also provide much needed info on what is silicone and why do we need it in our lives

Whether you are a frequent baker or an artist who likes to make resin jewelry, you must have heard about silicone.

It is a revolutionary gift of science that is non-reactive in the face of extreme temperatures and environmental conditions.

Thus, this stable polymer has become a popular material used in electronics, automobiles, aircraft, and more. 

It is also commonly used for making sealants and in HVAC systems. But that’s not all! Silicone cookware and bakeware have become hugely common.

They are also used in resin art and sculpture-making. It’s a tough material that doesn’t get destroyed easily.

So, the question is, how do you cut silicone? The material is not difficult to cut, with the right tool and method. Let’s take a look! 

So the question remains – How to Cut Silicone

It takes a complicated process to make silicone, a material that has become an essential part of every industry.

It is a highly durable material, but it sometimes needs to be cut for various uses. Using the right methods and devices, cutting silicone can be as smooth as cutting butter. 

Let’s start by discussing the four ways used for cutting silicone as used by industries. 

a) Manual Cutting

The most convenient way of cutting industrial silicone is by using the manual technique using a knife, box cutter, wire saw, etc. A template or stencil is used in the process.

Manual cutting is cost-effective because it does not involve expensive tools or machinery. 

But don’t forget to consider the cost of materials wasted and of rework. Also, consider the fact that the method might cause injuries.

Besides, manual cutting can lead to low quality of finishing, which can look unappealing to potential customers.  

b) Die Cutting

For die-cutting silicone, dies or metal tools with sharp edges are used. The equipment may be of two types – rotary or flatbed. Rotary die-cutting is much faster than flatbed die-cutting.

It is also more accurate. However, this means that they are costlier. 

Dies cut the silicone with the help of the exertion of pressure. If the finish is unsatisfactory, it is the result of a scrapped tool. This can add to the cost and time of the project.

But in large-scale production, the production of silicone parts of the same shape brings down the per-unit price.    

c) Water Jet Cutting

Water jet cutting is a unique method of cutting silicone at industrial levels without the use of tooling.

This means that it is a cost-effective method. Besides, with this method, it is possible to make revisions and complete the project in less time.  

It is used in prototyping and can handle up to a medium level of production. Another advantage of this method is that it can give smooth edges that bond easily.

It is also good at creating angles, holes, and other cuts. High-end factories use CAD for better accuracy.

d) Abrasive Water Jet Cutting

Abrasive water jet cutting is an advanced form of pure water jet cutting. It is such a powerful method that it can be used to cut metals.

As for silicone, abrasive water jet cutting may be useful in cutting metal that’s coated with silicone rubber. 

In this method, the water streaming out at high speed from the nozzle contains abrasive sand.

The water accelerates the sand to cut the material at hand with higher accuracy by applying high pressure on it. Thus, the features of pure water jet cutting reach a new level. 

e) Laser Cutting

Laser cutting is a high-speed method of shaping and cutting materials at industrial standards. The edges are smoothly cut, without any sign of chipping.

It can be used to cut even the thickest pieces of silicone at high speed, making it one of the best cutting technologies. 

It helps to achieve high levels of accuracy, and laser beams are also great at engraving silicone.

That is why laser cutting is often used in making jewelry, toys, and more. That’s because this method allows a high level of detail and precision.    

These methods are used at industrial levels, and each has its own advantages. They cater to different types of technical requirements of a business or industry. 

Cutting Silicone Manually for Individual Use

While the above techniques are highly useful in cutting silicone or silicone-layered metals, they are not for personal use.

You may need to cut silicone molds, sheets, or hoses if you like to handle small tasks of hardware or enjoy art. How do you cut silicone in that case? 

a) Cutting Tool

Cutting silicone manually demands sharp tools. The primary tool here is a sharp cutter, which may be a utility knife, scalpel, a curved cutting blade, or a mold cutter.

Your cutter needs to be extremely sharp, and preferably new so that you can get smooth results. 

b) Lubricant

Believe it or not, soap and water can come in really handy while cutting silicone.

You’ve guessed it right – it works as a fabulous lubricant! Soapy water can make the blade just glide across the silicone and maintain its sharpness.

But you’ll only need a small amount as silicone oil acts as a lubricant. Besides, the slippery water won’t take long to turn into a hazard and cause you to bleed. So be careful. 

c) Clamp

Clamps may also be used as a cutting guide to cut silicone hose or molds. There are different types of clamps available for this purpose.

T-Bolt clamps and liner clamps, made of stainless steel, are used to cut hose, while vise-style clamps can help to cut molds of large volumes without tiring you out. 

Other tools and accessories that will also be helpful to cut silicone include the following:

  • Gloves: Wear gloves while cutting silicone, as that will protect your hands from a possible injury.
  • Marker: Chalk is a delible marker to draw lines for measurements. You can also go for sharpies or pens for more permanent marks. 
  • Straight Edge/Stencil: The shape in which you want to cut the silicone can be perfected with a stencil or straight edge scale. 
  • Magnification: If you want accurate cutting, a magnification tool may be able to help you.  

Not all tools will be required for all types of silicone cutting. In general, if you’re not working in a factory, you may need to cut silicone hose, sheets, or molds. 

Cutting Silicone at Home

In general, you can cut silicone by following the steps below:

  1. Start by taking a clamp, scalpel, blade, or any other cutter. Make sure that it has a new and sharp blade.
  2. Take the silicone mold, hose, or sheet, and mark with chalk or sharpie. 
  3. If it is a sheet, lay it flat on the workstation and using a straight edge or stencil, mark the shapes or lines.
  4. If you’re using a clamp, tighten it securely to get a line to use as a cutting guide. 
  5. Using your cutter, start cutting the silicone.
  6. If you want to use soapy water, apply a small amount of it. 
  7. Remember to run the knife away from yourself and never in your own direction. 

There you go! You now know the easy way to cut silicone at home. These methods can come in handy while cutting different types of silicone.
