Plastics are malleable organic materials that can be extruded to form sheets or molded to form more complex shapes. Plastics come in many varieties, from commodity plastics like acrylic and ABS, to engineered plastics like polycarbonate and acetyl. Commodity plastics are inexpensive and have a broad range of applications, while engineering plastics are developed to meet certain performance requirements like high strength or high service temperature. Nearly all plastics can be processed by laser cutting, engraving, and marking. Visit our Materials Suppliers List for plastic vendors.

Types of Laser Processes

 

Lasers are playing an ever expanding role in material processing, from new product development to high volume manufacturing. For all laser processes, the energy of a laser beam interacts with a material to transform it in some way. Each transformation (or laser process) is controlled by precisely regulating the wavelength, power, duty cycle and repetition rate of the laser beam. These laser processes include the following:

Laser Annealing

Laser Cutting

Laser Drilling

Laser Engraving

Laser Etching

Laser Machining

Laser Marking

Laser Micromachining

Laser Perforating

Laser Photo Engraving

Laser Photo Marking

Laser Scoring

Laser Sintering

Laser Surface Modification

Selective Laser Ablation

All materials have unique characteristics that dictate how the laser beam interacts and consequently modifies the material. This is true whether one uses the laser system as a "laser cutter", "laser engraver", or "laser marker". The most common processes for plastics are the following:

 

 

uv Laser Cutting of Plastics

The energy of a water cooled uv laser beam is easily absorbed by most plastics, causing the material directly in the path of the laser beam to rapidly heat up and vaporize. If the laser power is sufficiently high, the laser beam will cut completely through the material. Most plastics vaporize quickly when cut with a laser, resulting in smooth and straight edges with minimal heat affected zone.

 

uv Laser Engraving of Plastics

La potencia del rayo láser ultravioleta enfriado por agua se puede limitar para que elimine (grabe) material a una profundidad específica. El proceso de grabado láser se puede utilizar para crear patrones y diseños intrincados en la superficie de plástico.

 

Marcado láser uv de plásticos

Ciertos plásticos cambian de color o tonalidad cuando se exponen a un rayo láser de fibra. Cuando la apariencia de la superficie cambia, sin que se elimine ningún material, el proceso se denomina marcado con láser. El marcado láser se puede utilizar para transmitir información, como el número de serie o el logotipo del fabricante.

 

Procesos Combinados

Los procesos de corte, grabado y marcado por láser descritos anteriormente se pueden combinar sin tener que mover o volver a fijar el material plástico.
