Laser Cutting

Laser cutting is one of the most widely used thermal power process-based non-contact types for cutting of materials. It involves the process of heating, melting and evaporating material in a small, well-defined area and can cut most plastics. The process is capable of cutting complex contour on plastics with high degree of precision and accuracy, making it ideal for a wide variety of manufacturing industries to produce a large number of components with high dimensional accuracy and surface finish.

Among the range of cutting technologies available, laser cutting has emerged as a transformative force, revolutionizing industries such as automotive, medical, electronics and aerospace. Alfa Chemistry's advanced laser cutting technology allows us to shape plastic materials with unparalleled precision, creating intricate patterns and precise geometries.

Advantages of Laser Cutting

Compared with other cutting processes, laser cutting has the following advantages.

• Laser cutting is a precise process that allows for the creation of detailed and intricate designs.
• Laser systems can cut or engrave materials quickly and efficiently.
• The laser cutting process is relatively easy to automate.
• The forces acting on the product during the cutting process are negligible.  Therefore, no special clamping of the workpiece is required in cutting of even the thinnest of materials.
• Cutting can be carried out in different directions in a plane and in space, which enable efficient cutting-out and trimming of shaped parts.
• Laser cutting is non-contact, eliminating the risk of mechanical damage to delicate materials.

Best plastics for laser cutting

The following are some of the plastics that are typically considered suitable for laser cutting:

While the plastics listed above do not release hazardous or toxic gases or particles that could harm your health. However, please note that proper ventilation and safety precautions are still essential.

The Best Laser for Cutting Plastics

While there are many different lasers to choose from, the best laser for plastics is the CO₂ laser. Here are the main reasons why CO₂ lasers are commonly used for cutting plastics:

• Wavelength: The wavelength range of the CO₂ laser is 9,000 to 10,600 nm. This wavelength can be well absorbed by many plastics to achieve efficient energy transfer and precise cutting.
• Power: CO₂ laser is the highest power laser, so it can cut plastics of various thicknesses.
• Minimal Melting: The CO₂ laser can effectively evaporate rather than melt the plastic, which helps to prevent undesirable melting, burrs, and rough edges.

It is important to note that when cutting plastics with a CO₂ laser, the higher power laser must be used at a slow setting to provide polished edges. If the part is cut too fast, the edges will be rough. If the laser cutter is too slow, then the edges will be distorted by the heat dissipated through the laser beam into the material.
