There are various products of laser engraving machines on the market. There are original imported machines, domestically designed and produced machines, imported machines assembled in China, professional Laser Engraver, professional marking machines, and professional cutting. Machine, there are machines that have more than two functions, so how to buy?
1) After-sales service:
The laser tube and reflecting lens of laser engraving machine are consumables, have a certain service life, and need to be replaced after expiration. This requires manufacturers to provide a strong after-sales service guarantee, can provide these supplies in a timely manner.
2) Product quality
It is also a laser engraving machine, but the components used are different. The following examples illustrate:
A) Stepping motor: related to Laser Engraver's engraving accuracy, some manufacturers choose imported stepping motors, some are joint-venture factory stepping motors, and some are non-branded motors.
b) Laser lens: It is related to the power of the laser engraving machine. It is divided into imported lenses, domestic lenses, and domestic lenses are divided into imported materials and domestic materials. The price gap is large, and the use effect and service life The gap is also wide.
C) Laser tube: This is the heart of the laser engraving machine. Due to the high price of imported laser tubes, which are generally tens of thousands of yuan, most domestic laser engraving machines use domestic laser tubes. The domestic laser tube is also good and bad, and the price gap is very large. Good laser tube life is generally around 3000 hours.
D) Mechanical assembly quality: In order to reduce costs, some manufacturers use very thin iron sheets to make machine casings, which are generally invisible to users. However, as time goes by, the frame will deform and affect the laser engraver's carving accuracy. A good laser engraving machine should adopt a frame structure, welded with high-quality steel, and use high-quality cold-rolled steel plates to make the casing. When the user purchases the machine, he can see if the quality is good or bad by using the frame structure and the thickness and strength of the casing iron sheet.
