Laser Cutting Of Nylon: Technique, Process, Applications & Benefits

“The way we handle nylon has been disrupted by laser cutting. Design Manufacturers can create intricate blueprints and increase overall production because of its precision, flexibility, and speedy cutting pros.”

Nevertheless, it might be difficult to achieve precise cuts using conventional techniques like shears, dies, or water jets. However, laser cutting produces clean, fast, accurate, efficient, and economical prospects from other traditional cutting methods. From smaller contours to larger holes with precision, and smooth finishes, laser cutting has become an increasingly popular technique.  Moreover, the integration of CNC laser cutting has advanced the technique for effectiveness and perfectness over the traditional one.

This blog covers the enormous potential of nylon for making it compatible with cutting through Laser. Moreover, we will walk through the benefits of Nylon Laser with its industrial upsides.

What is Laser Cutting of Nylon?

Manufacturers integrate laser beams for quality and speedy reaffirmations in their projects. Laser cutting of nylon is performed by using a beam of light, which melts, vaporizes, or burns away along the designated cutting path. This results in a clean, accurate cut with minimal heat-affected zones and little to no material distortion. 

Nylon sheet cutting with laser 

Due to its high precision and versatility, the technique has gained significant attention and become a preferred choice among design manufacturers. The core advantage of nylon is that it melts upon cutting and the laser beam precisely performs optimal cuts through it without deteriorating its chemistry. 

Additionally, nylon produces less material waste with minimal heat-affected zones. Even not only Nylon but several other laser cutting materials, such as metal, elastomers, and plastic, can be precisely cut through a concentrated laser beam.

Nylon: A Man-Made Thermoplastic

Nylon or polyamide fiber derived from petrochemical products. It is a flexible engineered thermoplastic that possesses high structural strength and toughness. 

Nylon Fiber

Nylon comes in numeral grades, such as nylon 6, nylon 6/6, and nylon 12, each grade offering exceptional benefits and limitations. Moreover, nylon offers distinguished features when compared to other thermoplastics in terms of malleability, and resistance to heat and stress. 

Likewise, high precision rates and accuracies are quite easy to achieve by utilizing nylon in laser cutting applications. 

How To Laser Cut Nylon?

There are some important considerations before starting your nylon fiber laser cutting project. A complete understanding of the laser cutting of the nylon process will facilitate in designing and selecting the appropriate laser method for your needs. 

Laser Cutting of Nylon

• The first step is to prepare a design file in vectorial configuration. You can use CNC software for designing that is intended for your requirements. 
• Then, the selection of the right cutting technique comes the way. Generally, CO2 Laser cutting is utilized for highly precise and complex geometries. It cuts with a power of around 40 to 120 KW. The selection criteria depend on the optimal resolution and cut precision.
• After selection, place the nylon sheet on the cutting bed to allow the laser to make optimal cuts through it. The smooth transition between digital design and physical placement of sheets plays a key role in this process.
• Initial testing on the targeted nylon fiber may be acquired to mitigate any machining flaws for smooth operations throughputs.
• After the cutting operation, the cooling and solidification phase integrates to solidify the sheet.
• Throughout this process, optimum conditions, such as pressure, temperatures, calibration, and beam alignment should be carefully controlled to avoid any misleading consequences.

Laser Cutting of Nylon: Things to Consider

Although there are numerous laser cutting advantages,  a few things need to be considered when working with nylon fiber;

• • The level of laser power coupled with the desired cutting speed is determined by how thick the nylon sheet is laid on the cutting bed.
  • Moreover, in laser cutting, nylon materials such as Nylon 6, Nylon 6/6, Nylon 11, and Nylon 12 are effectively processed using CO2 lasers with a wavelength of either 9.3 or 10.6 micrometers. 
  • However, it’s necessary to note that using a 1.06-micron fiber laser is not recommended for cutting nylon through CO2 laser cutting, as the material does not readily absorb the energy. 
  • Nylon off fumes and smell odors during the process of laser-cutting. So, it’s necessary to perform cutting operations in the proper venting environment to create a secure and healthful workplace.
  • Automatic Laser Cutting streamlines the process and results in relatively error-free outcomes.
  • In Laser cutting nylon, temperature control is crucially important as a minor mishandling can lead to wrapping and shrinkage problems during laser cutting.
  • The speed at which the laser moves across the nylon impacts the quality of the cut or engraving. That’s why experiments with different speeds are initially made to find the optimal balance between precision and efficiency. 

Nylon Grades For Laser Cutting

Normally, there are four grades of nylon, compatible with laser cutting and result in high precision and clean cuts to be made in various thicknesses and shapes.

Some of them are as follows:

Nylon 6

• Nylon 6 has relatively high tensile strength, toughness and impact resistance, and lustrous surface.
• It’s widely adopted by companies, such as; automotive, electronics, clothing, medicine, and consumer goods industries.

Nylon 66

• Nylon 6-6, or nylon 6/6 has high stiffness and comes with a crystalline structure, ultimately yielding more strength than other grades of nylon.
• This grade is broadly used in aerospace, automotive, and electrical industries also suitable for demanding applications such as gears and bearings.

Nylon 11

• It’s a biobased polymer.
• Nylon 11(PA 11) belongs to a polyamide family and is produced from petroleum oil.
• It has high impact resistance, flexibility, and chemical resistance properties.
• Nylon 11 brings outstanding pros to the automotive, oil and gas, and consumer goods manufacturing industries.

Nylon 12

• Nylon 12(PA 12) finds widespread uses and exhibits robust resistance to chemicals, bases, and salts. 
• Mostly, PA12 is employed by techniques, injection molding, 3D Printing, and laser engraving and cutting.

Techniques for Laser Cutting Nylon

Let’s take a closer look at the techniques of laser cutting appropriate to perform optimal cutting on nylon fiber. Here’s a table summarizing the different techniques used for cutting nylon:

What are the advantages of Laser Cutting of Nylon?

Laser-cutting nylon has possessed several benefits over conventional cutting techniques. Below, we’ll talk about a few of them.

• Since laser-cutting nylon produces a precise cut with minimal material waste, it is perfect for intricate designs and patterns, especially for small components and complex features.
• The integration of computerized cutting emphasizes accuracy with error-free outcomes.
• Laser cutting of nylon frequently results in smooth and clean edges with minimal risk of material deformation.
• There is no tooling and post-processing requirement for cutting nylon through a laser beam.
• Moreover, it offers more speedy iterations along with premium finishing.
• Less production cost for large volume production runs.
• During the process, the laser beam not only slices through the material but also effectively melts and seals the edges to pose an excellent surface finish.
• It minimizes the heat-affected zone (HAZ) around the cut edges while preserving the material’s conformity.
