Paronite is often used as a cushioning material that is durable, chemically resistant, and heat resistant. Paronite is commonly used in sealing systems and is often used to make gaskets of various shapes and sizes. Laser cutting offers an efficient, precise and clean solution for processing this material.
In this article, we will look at the process of preparing a file for laser cutting of a paronite gasket, as well as compare two cutting methods using different speed and power settings. We will evaluate the results to help you choose the best approach for your own applications.
Preparing the design file in RDWorks
First, we will need a vector file with an image of the gasket that we will cut. Using the RDWorks software, import your design by pressing CTRL+ I. For the test, we will create two versions of the same file to experiment with different cutting methods. The machine we use is equipped with a 90W Reci W2 CO2 laser, which is suitable for cutting paronite sheets.
Before starting work:
- Adjust the air pressure for optimal smoke removal and edge cleanliness
- Set the correct focal length using the focus sensor or ruler to ensure accurate beam concentration.
Now let’s move on to cutting strategies.
Cutting method 1: low speed, high power
In the first method, we set the laser to low speed and high power. This setting allows the laser beam to completely penetrate the paronite in one pass. Intensive energy supply ensures a clean cut, while slower movement allows the laser to burn through the entire sheet.
Advantages
- Fast processing in one pass
- Clean and uniform cutting edges
Considerations
- Higher thermal load on the laser tube
- The possibility of faster wear of optical components over time
Cutting method 2: high speed, low power, multi-step cutting

The second method uses high speed and lower power, and it is performed in several passes. Instead of cutting the material in one pass, the laser gradually removes the layers until the gasket is completely separated. This method places less stress on the laser system and the material itself, minimizing the risk of overheating or deformation of the material.
Advantages
- Softer impact on both the laser tube and the material
- Execution time is comparable to the first method
- Reduced risk of thermal damage or discoloration
Considerations
- Precise alignment of aisles is required
- It’s a bit more difficult to set up the software
Final results: edge quality and cutting efficiency
After conducting two tests, we noted that both methods allowed us to obtain smooth, well-defined edges. None of the methods resulted in the formation of fused areas, and we did not notice significant carbon residues. In terms of execution time, there was no significant difference between the two approaches.
However, if you are working with delicate materials, you have a low-power laser, or you want to extend the life of your laser tube, a multi-stage method may be the best option. It provides a more controlled and less aggressive approach while maintaining high quality results.
Conclusion
Laser cutting of paronite for the production of gaskets is a reliable and efficient process with proper settings. Whether you choose low speed at high power or high speed at low power over multiple passes, both methods are capable of delivering professional results. The right choice will depend on your specific production goals, machine capabilities, and the desired service life of your laser components.
By carefully preparing files, adjusting air pressure and focal length, and experimenting with cutting strategies, you can get clean and precise pads with minimal post-processing, which will improve both your workflow and the performance of your final product.
