Understand Your Material Needs

The first step in choosing a laser machine is understanding what materials you’ll be working with. Whether you're engraving or cutting, different lasers work better with certain materials. For example, CO2 lasers are fantastic for non-metal materials like wood, acrylic, and leather. On the other hand, fiber lasers are optimal for metals such as steel, aluminum, and brass.

When I first started at Kirin Laser, this was the first question I asked every customer: "What materials are you working with?" Trust me, the machine you choose needs to match your material needs, or else you're going to end up spending more time and money than you intended.

Production Volume and Speed

Another important consideration is the production volume and speed of your business. Are you looking to produce small batches of customized items, or are you planning for mass production? If you need high speed and precision, a fiber laser might be a better choice, especially for cutting metal. CO2 lasers, while still efficient, can be slower when cutting thicker materials.

This is something that’s often overlooked, but I promise you, it’s critical. You don’t want a machine that can’t keep up with your growing business. On the flip side, don’t overinvest in a machine that’s too powerful for your needs. After all, overkill leads to unnecessary costs!

Laser Power: What’s Enough for You?

Laser power plays a huge role in the type of work your machine can handle. Generally, a higher-powered laser will cut through thicker materials more easily, but it can also be overkill for thinner materials. For instance, a 50W CO2 laser might be perfect for engraving on glass, but a 150W laser is required if you want to cut thick acrylic or wood.

When you're deciding on power, you’ll need to balance the materials you work with and the thicknesses you encounter most often. But don’t let power numbers intimidate you! It’s all about finding a sweet spot between capacity and your typical workloads.

Choosing The Right Power for Your Business

When selecting laser power for engraving different materials, it is indeed necessary to consider multiple factors comprehensively to ensure the engraving quality and protect the material. The types of materials you mentioned have different power requirements and technical demands in laser engraving:

Material Hardness

1. Soft Materials (e.g., wood, leather, rubber)
   These materials have lower hardness and generally require relatively lower laser power. For example, when engraving wood, a CO₂ laser marking machine with a power range of 30–100 watts typically achieves excellent results. For thin leather (thickness less than 3mm) and rubber products, a power range of approximately 20–50 watts is sufficient for effective engraving. Excessive power may cause the material to burn or carbonize excessively, affecting the engraving quality.

2. Hard Materials (e.g., metal, stone, glass)
   Engraving metal materials (such as stainless steel and aluminum alloy) often requires higher power. When using a fiber laser marking machine for metal engraving, the power generally ranges between 20–500 watts. Thicker metals or cases requiring deep engraving may need even higher power. For stone (e.g., granite, marble) and glass, due to their high hardness and sensitivity to thermal shock, power selection should be moderate. Typically, a green laser marking machine uses around 5–20 watts for glass engraving, while stone engraving may require 50–200 watts. Additionally, the laser's pulse characteristics should be considered to reduce thermal impact.

Material Thickness

1. Thin Materials (thickness less than 3mm)
   For materials like thin plastic sheets and thin metal foil, lower power can penetrate and engrave effectively. For example, acrylic plastic with a thickness of 1–3mm can be effectively engraved with a CO₂ laser power of 30–50 watts, producing clear patterns and text. For thin metal foil (thickness less than 1mm), using a fiber laser power of 10–30 watts is sufficient for marking.

2. Thick Materials (thickness greater than 3mm)
   When materials are thicker, sufficient laser power is needed to ensure engraving depth. For instance, engraving wood with a thickness of 5–10mm may require a CO₂ laser power of 100–200 watts. For metal materials thicker than 5mm, a fiber laser power of 300–500 watts or higher may be necessary, and multiple engraving passes might be needed to achieve the desired depth and effect.

Engraving Depth Requirements

1. Shallow Engraving (depth less than 0.5mm)
   For surface markings, such as product serial numbers or simple patterns, lower power is sufficient for most materials. For example, marking a brand logo on a plastic shell can be achieved with a laser power of 10–30 watts. Marking simple text on a metal surface can be accomplished using a fiber laser power of 10–50 watts.

2. Deep Engraving (depth greater than 0.5mm)
   When deep engraving is required, such as creating three-dimensional models or engraving patterns on molds, higher power is necessary. For example, engraving a relief pattern with a depth of 1–2mm on stone may require a laser power of 100–300 watts. For metal mold engraving with a depth exceeding 1mm, a power range of 200–500 watts may be needed.

Material Laser Absorption Characteristics

1. High Absorption Materials (e.g., most non-metal materials for CO₂ lasers)
   Materials like wood, leather, and plastic have high absorption rates for CO₂ lasers, so relatively lower power can produce excellent engraving results. For example, wood absorbs the 10.64μm wavelength of a CO₂ laser well, and a power range of 50–100 watts can meet most engraving needs when engraving wooden crafts.

2. Low Absorption Materials (e.g., metals for CO₂ lasers)
   Metals have low absorption rates for CO₂ lasers but relatively high absorption rates for fiber lasers. Therefore, when engraving metals, a fiber laser should be used, and the power should be adjusted according to the specific situation. For example, aluminum alloy absorbs fiber lasers well, and a power range of 100–300 watts may be needed for deep engraving to ensure the desired effect.

Precision: It’s All in the Details

The beauty of laser engraving lies in its ability to create intricate details that you can’t achieve with traditional methods. That said, the precision of the machine is vital, especially if you're dealing with small or detailed engravings. When choosing a laser machine, pay close attention to its resolution capabilities.

At Kirin Laser, we often talk about resolution when showing customers our fiber and CO2 laser machines. Whether you’re engraving logos, serial numbers, or even artwork, the clarity of those fine details depends on the resolution of your laser. Machines with higher resolution and finer spot sizes are ideal for those looking to create intricate patterns or detailed engravings.

Cost Considerations

Let’s talk about the elephant in the room — cost. Buying a laser machine is an investment, and it's one that should be carefully evaluated. There’s a balance between upfront cost and long-term savings. While high-end models might cost more, they can be more efficient, require less maintenance, and have a longer lifespan. But remember, a cheaper option doesn’t always mean bad quality — it could simply mean you’re compromising on certain features like speed, power, or material compatibility.

Think about what your business can afford and what you’re willing to invest in the future. My best advice? Don’t go for the cheapest option if it doesn’t meet your production needs. You’ll end up spending more in the long run when you need to upgrade.

Maintenance and Support

Maintenance is another factor you shouldn’t overlook. No matter how high-tech your machine is, it will require upkeep. Look for a supplier that offers good customer support and easy access to replacement parts. In my experience, one of the worst things that can happen is having a machine break down during a critical job with no immediate support.

At Kirin Laser, we pride ourselves on our after-sales service. If you choose one of our laser machines, we provide training, technical support, and maintenance assistance to keep your equipment running smoothly. A machine without support is like a car without insurance — not something you want in your business.

How to Maintain Laser Marking Machine?

1. Optical System Maintenance

   • Lens Cleaning: The lenses of laser marking machines are prone to accumulating dust and dirt, which can affect the transmission and focusing of the laser. Regularly (recommended once a week) clean the lenses using specialized lens cleaning paper and cleaning solution. When cleaning, gently wipe the lens to avoid scratching the surface.

   • Check Optical Path Alignment: Proper alignment of the optical path is crucial for ensuring the precision of laser marking. Periodically (e.g., once a month), use optical path calibration tools to check if the laser beam path has shifted. If any misalignment is detected, perform fine adjustments according to the equipment's operation manual to restore the optical path alignment.

2. Laser Source Maintenance

   • Cooling System Inspection: During operation, the laser source generates heat, requiring a cooling system to ensure its normal functioning. Regularly (weekly) check the water level of the cooling system (if it is water-cooled) or the operation of the fans in a air-cooled system. For water-cooled systems, ensure the quality and level of the coolant, and replenish or replace the coolant as necessary.
   • Laser Power Monitoring: Periodically (quarterly) monitor the output power of the laser source using a power meter. If a decrease in laser power exceeds a certain range (e.g., 10%), it may indicate laser source aging or other faults, and professional maintenance personnel should be contacted for inspection and repair.

3. Mechanical Components Maintenance

   • Lubrication of Moving Parts: The moving components of the laser marking machine (such as galvanometer motors and worktable drive screws) require regular lubrication to reduce wear and friction. Depending on the frequency of use, lubricate the moving parts with an appropriate amount of lubricant every 1 to 3 months.
   • Check Mechanical Structure Stability: Periodically (every six months) inspect the mechanical structure of the equipment, including the machine frame and worktable, for any looseness or deformation. If issues are found, tighten the screws or adjust the mechanical structure promptly to ensure the stability and precision of the equipment.

4. Electrical System Maintenance

   • Electrical Connections Inspection: Regularly (monthly) check the electrical connections of the equipment, including power cables and signal lines, to ensure they are secure. Loose connections can cause equipment malfunctions or unstable operation. If any looseness is detected, tighten the connections promptly.

   • Clean the Electrical Control Cabinet: Dust accumulation inside the electrical control cabinet can affect the cooling and normal operation of electrical components. Every 3 to 6 months, use a clean brush and a hairdryer (with a cool air setting) to clean the inside of the electrical control cabinet, removing dust and debris.

5. Working Environment Maintenance

   • Maintain Clean and Dry Conditions: The laser marking machine should be placed in a clean and dry environment. Avoid placing clutter around the equipment to prevent dust and debris from entering the internal components. If the working environment has high humidity, use dehumidifying equipment to reduce the humidity levels.
   • Temperature Control: The temperature of the working environment also affects the performance of the laser marking machine. The ideal operating temperature is generally between 18°C and 25°C. If the ambient temperature is too high or too low, it may impact the stability of the equipment and the laser output power, necessitating appropriate temperature control measures.

Software Compatibility

Another often-overlooked aspect is the software that accompanies the machine. Not all laser machines are compatible with the same design software, so you need to check if the laser system works with the software you're using. For example, some machines are optimized for AutoCAD, while others may use proprietary software.

If you already have a design pipeline in place, you want a laser machine that will integrate smoothly with it. If you don’t, don’t worry! Many laser machine providers, including us at Kirin Laser, offer solutions with user-friendly software that can get you up and running without a steep learning curve.

Environmental Considerations

It’s important to take into account the environmental impact of the laser machine you’re considering. Laser machines can use significant amounts of power, and certain models produce more heat than others. Consider choosing a machine that aligns with your sustainability goals.

At Kirin Laser, we prioritize energy-efficient models that reduce power consumption without compromising on performance. So, if sustainability is a key focus for your business, be sure to ask about energy-saving options.
