Not all marking machines are the same. Some people buy the first laser marking machine they see without thinking about which type of laser marking equipment is best for their needs. This can cause a lot of problems, so take the time to figure out which type of marking machine you have before buying
It's important to be right for you.
#fiber laser marking machine
The fiber laser marking machine uses a fiber laser to output laser light, and then realizes the marking function through a high-speed scanning galvanometer system.
The fiber laser marking machine uses a laser beam to mark permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the desired etching pattern. , text, barcodes and other graphics.
Pros
1. It can process a variety of metal and non-metal materials. In particular, it is more advantageous to mark high hardness, high melting point and brittle materials.
2. It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality.
3. High processing efficiency, computer control, easy to realize automation.
4. Long service life, the service life of fiber laser marking machine is up to 100,000 hours
Cons
The marking depth is small. Since the laser of the fiber laser marking machine is parallel light, its focus is on the surface of the workpiece, and the more it goes to the inner layer of the workpiece, the smaller its force is.
Application field: It is used in the marking of stainless steel, aluminum products and other metals, plastic products, IC, mobile phone buttons, clocks, mold industry, bitmap and other marking operations.
#CO2 Laser Marking Machine
It is a laser equipment that realizes marking by passing the laser beam through beam expansion, galvanometer, focusing, and controlling the deflection of the galvanometer.
Pros
It is suitable for marking, engraving, hollowing and cutting of various non-metallic materials and products.
Various characters, symbols, graphics, images, barcodes, serial numbers, etc. can be marked, engraved, hollowed out, and cut.
cons
Co2 laser marking machine cannot mark products made of metal materials
The carbon dioxide co2 laser marking machine has a high heat gas conversion rate, and the operating temperature is easy to rise. Generally, a water-cooled chassis is required for cooling.
Application areas: electronic components, instrumentation, clothing, leather, luggage, shoes, buttons, glasses, food, beverages, cosmetics, packaging, electrical equipment, etc.
#UV marking machine
Ultraviolet laser machines rely on laser energy to break the bonds between atoms or molecules, making them gasify and evaporate into small molecules. because
Pros
The focusing spot is extremely small, the cold light source is smoke-free, pollution-free, does not damage the surface of the material, and has little processing impact, so it can be used for fine marking and special material marking.
cons
1. The UV laser machine is the laser marking machine with the shortest life among all light source marking machines;
2. The required environment, temperature, working time and other factors.
Application areas: used in cosmetic, pharmaceutical, food and other polymer material packaging bottle surface marking; flexible PCB board marking, scribing; silicon wafer micro-hole, blind-hole processing; LCD liquid crystal glass, glassware surface, Metal surface coating, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
Buyer's Guide
Different industries have different choices for different types. Thinking about the characteristics of your industry will help you determine the most suitable type.
Purpose
Think about what and how often you will use it. This will help determine the laser type, power output, and capabilities that best suit your needs.
Budget
Just like anything else, laser marking machines can cost anywhere from budget friendly to luxurious. Determine how much you're willing and able to spend upfront on an item, and what maintenance costs you'll accept over the long term.
in conclusion
If your industry has assembly line marking requirements, information traceability requirements, long-term marking requirements, and refined marking requirements, then owning a laser marking machine is a wise investment. Laser marking machines are suitable for most materials in industrial production at this stage.
