This trend presents a significant challenge to traditional manufacturing methods, as these methods often struggle to meet the requirements of complex and detailed designs, as well as small-batch production. Laser cutting machines are now being used more and more widely in this industry. However, a key question remains: how can different types of laser cutting machines maximize their value in the gift industry? What are the application cases? This article will provide the answers.
Laser Cutting Machine Basics (Fiber Metal Laser Cutting Machine & CO2 Laser Cutting Machine
Working Principles
There are two main types of laser cutting machines widely used in the craft gift industry: fiber laser cutting machines and CO2 laser cutting machines, each with distinct working principles.
Fiber laser cutting machines operate by generating a high-energy laser beam via a fiber laser generator. The generated intense heat from this laser beam rapidly melts or vaporizes the material. Simultaneously, the cutting head ejects high-pressure gas. This high-pressure gas blows away the melted or vaporized substance, creating a narrow and smooth cutting edge, thereby enabling the cutting of metal materials. Characterized by high-quality fiber optic beams and an extremely small heat-affected zone (usually less than 0.1 mm), fiber laser cutting machines are particularly suitable for metal processing.
In contrast, CO2 laser cutters produce laser light through a gas-filled tube. Inside this tube, a mixture of carbon dioxide, nitrogen, and helium undergoes electrical excitation. The laser beam with a wavelength of 10.6 μm is efficiently absorbed by non-metallic materials, leading to effective vaporization and cutting. It is the disparities in energy transmission and material interaction between these two types of laser cutting machines that determine their applicability to different materials.
Equipment Components
A laser cutting machine comprises several essential components, each playing a pivotal role in the craft gift – making process. The laser generator stands as the heart of the machine, tasked with producing the laser beam. In fiber laser cutting machines, renowned brands such as IPG and Raycus offer high – quality fiber laser generators. These generators ensure a stable and powerful energy output, which is indispensable for cutting tough metals, enabling the creation of intricate metal – based craft gifts.
When it comes to CO2 laser cutting machines, gas – filled laser generators are crucial. Well – known brands like Coherent and Trumpf are leaders in this domain, providing reliable generators that are essential for the effective operation of these machines, especially when working with various non – metallic materials commonly used in craft gift production.
The control system serves as the brain of the laser cutting machine. It precisely manages the movement of the cutting head and allows operators to adjust critical parameters, including laser power, speed, and focus. By inputting specific design patterns, operators can rely on the control system to execute cuts with high precision, ensuring that each craft gift meets the desired design specifications.
The worktable, on the other hand, offers a stable foundation for the materials. Its size and structure have a direct impact on the production capacity. For instance, a larger worktable provides the flexibility to process bigger craft gift items, facilitating the creation of elaborate and oversized decorative pieces. Additionally, it enables handling multiple pieces simultaneously, significantly enhancing production efficiency, which is highly beneficial for both small – scale and large – scale craft gift manufacturers.
Laser Machine Selection
When it comes to material processing, the choice between fiber laser cutting machines and CO2 laser cutting machines depends on the type of material. Fiber laser cutting machines are best suited for processing metal materials such as stainless steel, copper and aluminum. These machines can handle the high reflectivity and high thermal conductivity of metals with clean cuts and narrow kerfs. Non-metallic materials such as acrylic, wood, and leather are better suited for CO2 laser cutters; the CO2 laser effectively vaporizes these materials for detailed engraving and intricate cutting. Key selection criteria include the power output of the machine (which should be matched to the thickness and hardness of the material) and the precision of the cutting head (which is critical for realizing the fine details in the design of the craft gift).

Common Issues and Solutions in Laser Cutting
Metal Processing Problems
- Incomplete Cutting: When metal is not cut through completely, it could be due to laser power decay. Normally, the laser power should decay less than 5% per year. Checking the power output and adjusting the focal position can solve this problem. If the focal point is not correctly set, the laser energy may not be concentrated enough to cut through the metal.
- Excessive Burrs: To reduce burrs, decreasing the cutting speed and increasing the pressure of the assist gas can be effective. Slower cutting allows for more controlled melting and vaporization of the metal, while a higher – pressure assist gas blows away the molten material, resulting in cleaner edges.
- Deformation: Metal deformation during cutting can be minimized by using a segmented cutting method, which reduces heat accumulation. Additionally, adding more fixtures to firmly hold the metal in place can prevent it from warping or bending.
Post – Processing Techniques
After cutting metal craft gifts, post – processing is essential to enhance the quality. Sanding can smooth out rough edges, and polishing can give the metal a shiny finish. Coloring techniques, such as electroplating or powder coating, can add vibrant colors and protect the metal from corrosion, making the craft gifts more appealing.
Non – Metal Processing Problems
- Edge Carbonization: For non – metallic materials like wood and acrylic, edge carbonization can occur. Reducing the laser power, increasing the cutting speed, and enhancing the blowing gas flow can prevent this. Lower power and faster speed reduce the heat exposure to the material, while a stronger gas flow blows away the vaporized material and prevents it from burning.
- Blurred Engraving: Blurred engraving on non – metallic materials can be caused by dirty lenses or incorrect focal length. Cleaning the lenses regularly and adjusting the focal length within an error range of ±0.1mm can improve the clarity of the engraving.
- Material Combustion: Since non – metallic materials like wood and leather are flammable, pre – spraying flame retardants can help. Also, setting up an effective smoke exhaust system is crucial to remove harmful fumes and ensure a safe working environment.
