CO2 Laser Engravers

CO2 lasers are particularly suitable for engraving and cutting non-metallic materials and can also process thin metals in certain cases. They are incredibly versatile, quick, and efficient, making them a favorite of DIY hobbyists and crafters.

Low Power (20W - 40W):

Applications: Engraving thin non-metallic materials like paper, cards, thin leather, and thin plastics. Commonly used for making business cards, paper products, and lightweight crafts. Surface marking on materials like wood, acrylic, and glass.
Advantages: High precision for fine engraving, low energy consumption, suitable for small studios or individual users.
Disadvantages: Limited cutting ability for thick materials, slower cutting speed.

Medium Power (50W - 80W):

Applications: Engraving and cutting medium-thickness non-metallic materials like 5-10mm wood, acrylic, leather, and plastic. Used for making signs, crafts, and models. Versatile processing for both engraving and cutting. Ideal for small businesses or workshops.
Advantages: Wide range of applications, good cost-performance ratio, faster processing speed and higher efficiency compared to low power.
Disadvantages: Limitations in cutting very thick materials. Multiple passes or reduced speed may be required when processing very thick materials.

High Power (100W - 150W and Above):

Applications: Engraving and cutting thick non-metallic materials over 10mm, such as wood, acrylic, and other non-metals. Used for making furniture, thick plate crafts, signs, and large models. High-efficiency batch production. Some metal marking and cutting, especially for coated or oxidized metals.
Advantages: Strong cutting ability, high production efficiency, suitable for high-intensity processing tasks.
Disadvantages: Higher equipment and operating costs, suitable for enterprises with large processing needs.

Summary

Low Power (20W - 40W): Suitable for fine engraving and shallow marking of thin materials, ideal for small workshops, artists, and individual users.
Medium Power (50W - 80W): Suitable for versatile processing of medium-thickness non-metallic materials, ideal for small and medium-sized enterprises and multi-purpose processing needs.
High Power (100W - 150W and above): Suitable for high-efficiency cutting and deep engraving of thick materials, ideal for industrial applications requiring high production efficiency.

Fiber Laser Engravers

The power selection for fiber laser engravers depends on the material type, engraving depth, cutting thickness, and production efficiency requirements. Fiber lasers excel in metal processing but can also be used for certain non-metallic materials.

Low Power (20W - 50W):

Applications: Metal marking and shallow engraving on stainless steel, aluminum, copper, etc. For example, engraving words, patterns, or QR codes onto tools, electronic product casings, nameplates, and medical devices. Thin metal cutting, usually under 1mm. Marking on plastics, ceramics, and PCBs.
Advantages: Low-wattage fiber lasers can provide extremely high precision in marking and engraving, making them ideal for precision processing. Due to their lower energy output, the heat-affected zone is smaller, reducing material deformation.
Disadvantages: Limited cutting ability for thicker or harder materials.

Medium Power (50W - 150W):

Applications: Deeper metal engraving, medium-thickness metal cutting (2-5mm stainless steel or aluminum), high-efficiency marking in batch production.
Advantages: It can process a variety of materials and is suitable for both engraving and cutting. At medium wattage, the laser can provide faster processing speeds while maintaining high precision.
Disadvantages: Higher equipment cost compared to low power.

High Power (150W - 500W and Above):

Applications: Suitable for cutting metal materials over 5mm in thickness, such as stainless steel, carbon steel, and aluminum alloys. Widely used in industries like automotive manufacturing, shipbuilding, and mechanical processing. With high power support, it can achieve rapid engraving and cutting in large-scale production. Suitable for industries demanding high speed and high-quality processing.
Advantages: High-power fiber lasers can cut extremely thick metal materials while maintaining excellent cut quality. It can significantly reduce production cycles and increase processing speed, making it an ideal choice for mass production.
Disadvantages: High equipment and maintenance costs.

Summary

Low power (20W - 50W): Suitable for precision marking, shallow engraving, and thin metal cutting, ideal for small parts and high-precision applications.
Medium power (50W - 150W): Suitable for versatile processing needs, can handle various non-metallic materials and some thin metals, ideal for small and medium-sized workshops.
High power (150W - 500W and above): Suitable for industrial-grade tasks requiring higher speed and depth, can perform deep engraving and fast marking, ideal for medium-to-large batch production.
