How Laser Cutting Enhances Plastic Sheet Applications
Whether you’re designing parts for medical devices, aerospace components, or flexible electronics, the choice of cutting method matters. Laser cutting is increasingly popular for advanced plastics like PEEK, Kapton, and Cirlex due to its ability to produce consistent, high-quality results.
Tips for Designing Plastic Parts for Laser Cutting Sheets
Use CAD Software
Precise designs ensure that the laser follows exact dimensions and paths.
Consider the Material
Thin films like Kapton may require different laser settings compared to thicker materials like PEEK.
Account for Thermal Properties
Some plastics, such as Cirlex, are highly resistant to heat, making them ideal for laser cutting with minimal distortion.
What Can You Create with Laser-Cut PEEK?
PEEK is one of the most versatile and high-performance plastics available, and laser cutting takes its potential even further. From intricate gaskets and shims to critical medical implants and catheters, laser technology enables the precise fabrication of PEEK parts for a wide range of industries. Whether you need durable belt filters, efficient battery separators, or components for demanding environments, laser cutting delivers the accuracy and consistency needed for complex designs.
Laser cutting also eliminates the need for tooling, making it ideal for low-volume production, rapid prototyping, and high-mix manufacturing where speed and adaptability are key. Explore the infographic to discover the full range of innovative parts you can create from laser-cut PEEK and other high-performance plastics.
Processing plastic sheets with laser technology offers a range of benefits: clean, burr-free edges, exceptional accuracy for complex geometries, and the ability to handle materials as thin as films or as thick as heavy-duty sheets.
PEEK’s versatility and performance make it a standout material for precision parts, but it’s just one of many plastics that excel with laser cutting. Materials like Kapton and Cirlex are ideal for high-temperature or electrically insulative applications, while acrylic and polycarbonate provide solutions for optical clarity, impact resistance, and lightweight durability.
