Types of thick foam laser cutting machine
Thick foam laser cutting machines have set a new standard in precision cutting. These machines deploy powerful laser technology to yield detailed and accurate cuts on foam materials, including thick foam, thereby ensuring minimal wastage of foam material. Several types of thick-foam laser-cutting machines have emerged to cater to diverse cutting needs and requirements.
CO2 Laser Cutting Machines
Typically, CO2 Laser Cutting Machines employ carbon dioxide as the medium through which the laser light is generated. This type of laser cutting machine is particularly well suited to cutting or engraving thick foam, as it provides a delicate balance between cutting power and surface finish. CO2 lasers are widely used in industries ranging from manufacturing to sign making.
Fiber Laser Cutting Machines
Fiber laser cutting machines utilize a solid rod as the medium, normally a fiber made of glass that generates the laser light. Fiber lasers have higher energy density, allowing them to cut through thicker materials more effectively than CO2 lasers. While principally utilized for metals, manufacturers increasingly use fiber lasers for cutting dense or thick foam.
Hybrid Laser Cutting Machines
Hybrid laser cutting machines combine the strengths of both CO2 and fiber laser technologies. To put this in perspective, these machines are designed with two laser sources, enabling users to switch between CO2 and fiber lasers, depending on whether the project involves thick thermoplastic or advanced engraving on dense foam. This flexibility makes hybrid laser cutting machines ideal for industries that require various laser cutting applications. Furthermore, the dual-laser capability provides a more comprehensive solution for businesses that need to cut different materials, including thick foam laser cutting, high-precision metal cutting, or even intricate designs on thick foam sheets for product packaging.
Galvo Laser Cutting Machines
Galvo laser cutting machines use mirrors to redirect the laser beam for fast cutting. This can be particularly advantageous for projects with large foam sheets or when speed is a primary concern. Galvo machines are favored in high-volume production scenarios where speed without compromise of quality is often needed to keep up with production requirements.
