Tips for choosing laser engraving machines in different industries

There are many kinds of laser engraving machines on the market , including imported machines, domestically designed and produced machines, machines assembled domestically with imported parts, professional engraving machines, professional marking machines, professional cutting machines, and machines with more than two functions. So how should we choose?

1) After-sales service:

The laser tube and reflective lens of the laser engraving machine are consumables with a certain service life and need to be replaced after expiration. This requires the manufacturer to provide strong after-sales service guarantees and provide these consumables in a timely manner.

2) Product quality

The same laser engraving machine uses different parts. Here are some examples:

a) Stepper motor : It is related to the engraving accuracy of the laser engraving machine. Some manufacturers choose imported stepper motors, some use stepper motors produced by joint ventures, and some use unknown brand motors.

b) Laser lens: It is related to the power of the laser engraving machine . It is divided into imported lenses and domestic lenses. Domestic lenses are divided into two types: those made of imported materials and those made of domestic materials. The price difference is large, and the difference in use effect and service life is also large.

c) Laser tube: This is the heart of the laser engraving machine. Since the price of imported laser tubes is expensive, generally tens of thousands of yuan, most domestic laser engraving machines use domestic laser tubes. Domestic laser tubes are also mixed, and the price difference is large. The service life of a good laser tube is generally about 3,000 hours.

d) Mechanical assembly quality: In order to reduce costs, some manufacturers use very thin iron sheets to make the machine casing, which is generally not visible to users. However, over time, the frame will deform, affecting the engraving accuracy of the laser engraving machine. A good laser engraving machine should adopt a frame structure, welded with high-quality steel sections, and made of high-quality cold-rolled steel plates to make the casing. When users buy a machine, they can find out the quality by looking at whether the frame structure is used and the thickness and strength of the casing iron sheet.

3) Functions of the machine:

Some people who are familiar with laser engraving machines lament that the configuration of laser engraving machines has increased so much, but the price has dropped compared with previous years. How gratifying! But someone immediately said, don't be fooled by those bright external things. If you compare the reliability and the convenience and affordability of maintenance services, many new equipment are not as good as the "old three" in previous years. The author believes that users should pay more attention to the cost performance of laser engraving machines. Laser engraving machines with "medium configuration and moderate price" are our best choice. Many users have fallen into a misunderstanding and hope that the laser engraving machine they bought is "all-round" and can do everything. This is actually a big mistake. The following is an explanation from the perspective of the purpose of purchasing a laser engraving machine:

a) Engraving rubber plates for carton printing:

Most laser engraving machines can be used to engrave rubber plates. You don’t need to choose those machines with many functions and high speed, because you rarely use those functions. You can’t use the high speed of engraving because the
engraving depth of the rubber plate cannot meet the printing requirements. Recommendation: Buy a laser engraving machine suitable for engraving rubber plates, which is cheap and has a fast return on investment.

b) Carving crafts:

Most laser engraving machines can be used to engrave handicrafts. You should choose according to your requirements:

Carving bamboo slips, wooden boards, and small ornaments: choose a small machine, such as a 300X400 format machine, which is cheap and has high precision. Carving wooden boxes and wine boxes: choose a 500X700, 600x900 format machine, and it must have a lifting platform, otherwise the long wooden box cannot be put in.

Carving bamboo tubes and tea tubes: Choose a machine with a format of 500X700, 600x900, with a lifting platform and equipped with a rotating engraving device.

Carving large woodblock prints: Choose a machine with a format of 600x900, and require a lifting platform, and the material can be passed through the front and back of the machine, so that carving large-sized wooden boards can be done with ease.

Making New Year's cards: Choose a machine with a format of 500X700, 600x900, and a cutting platform and a fast cutting speed, otherwise the edges of the paper will turn yellow.

c) Cutting acrylic sheets

Most laser engraving machines can be used to cut acrylic sheets, but I recommend choosing a dedicated laser cutting machine, because laser cutting machines are optimized for laser cutting and have very good cutting effects. If you still insist on buying an ordinary laser engraving machine, you must choose a laser engraving machine with a "knife bed" device. Remember: Don't believe some manufacturers who say that 60w or 80w machines can cut 20mm thick acrylic. This is impossible. Even if they can barely cut through, the cutting edge is terrible. Normal value:

A 60w laser engraving machine can cut 8-10mm acrylic.

An 80w laser engraving machine can cut 8-15mm acrylic.

d) Clothing, leather carving and cutting

Choose a laser engraving machine with fast cutting speed and honeycomb cutting platform

Summarize:

When purchasing a laser engraving machine, you should choose a model that can meet production tasks and save costs based on your own production capacity and hardware facilities. At the same time, you should pay attention to the detailed performance and after-sales service of the equipment, and confirm the processing effect of the equipment.
