Laser Cutting For PEEK


Polyether Ether Ketone, commonly known as PEEK, belongs to the family of high-performance polymers renowned for their exceptional stability and resistance to harsh environmental conditions. Its remarkable combination of high-temperature resistance, chemical inertness, and mechanical strength positions PEEK as a prime choice for applications in aerospace, medical, automotive, and other industries where reliability is paramount.

Laser cutting has emerged as a transformative technology, offering unparalleled precision and versatility across various materials. When it comes to PEEK, laser cutting stands out as an ideal method due to its ability to produce intricate shapes and maintain tight tolerances. The process involves the use of a high-powered laser beam that melts, burns, or vaporizes the material, resulting in clean, precise cuts without the need for physical contact.

The Material Of PEEK Laser Cut


Polyetheretherketone (PEEK) is available in various grades and formulations, each designed to meet specific performance requirements for different applications. When considering laser cutting, the type of PEEK most commonly used is unfilled or standard PEEK grades.

These unfilled PEEK grades, often referred to as “virgin” or “neat” PEEK, are the base polymers without any additives or reinforcements. They possess excellent properties and are suitable for laser cutting due to their relatively consistent composition and uniform structure. Unfilled PEEK maintains its integrity during laser cutting processes, allowing for precise and clean cuts.

However, it’s important to note that some specialized PEEK grades might contain fillers, reinforcements, or additives that can influence the laser cutting process. For instance:

1

PEEK with Carbon Fiber or Glass Fiber Reinforcements

These reinforced PEEK grades are engineered to enhance specific properties such as mechanical strength, stiffness, or wear resistance. While they offer improved performance in certain applications, the presence of fibers or fillers may affect laser cutting parameters due to differences in material composition.
2

PEEK with Additives

Some PEEK formulations incorporate additives to modify properties like conductivity, lubricity, or flame resistance. The presence of certain additives may impact the absorption of laser energy, potentially requiring adjustments in laser settings for optimal cutting results.

When laser cutting PEEK with additives or reinforcements, it’s essential to consider the specific composition and characteristics of the material. Laser parameters such as power, speed, and focus might need to be adjusted to accommodate the variations in material composition and ensure clean, precise cuts without compromising the properties of the finished parts.

In most cases, standard, unfilled PEEK grades are preferred for laser cutting due to their consistent composition and compatibility with laser cutting processes. However, if using specialized grades with additives or reinforcements is necessary for specific application requirements, careful consideration and testing of laser cutting parameters are crucial to achieve desired cutting results while preserving the material’s properties. Consulting with material suppliers or conducting test cuts can help determine the optimal laser cutting parameters for these specialized PEEK grades.
