If you intend to purchase a laser engraver, open Internet or Baidu search google, wow! Flocked to the various brands at a loss so that you really want to spending gradually charming eyes, how to sell it? What is that we must carefully consider the factors? An expert has come out of China for the laser equipment praise that it is China’s laser industry, an important indicator of progress. However, when a variety of brands that frequently going to want to become charming eyes spending today, how do we choose?
1) after-sales service:
laser engraver laser tube, reflective lenses are consumables, have a certain life, to be replaced after the expiration. This requires manufacturers to provide a strong after-sales service guarantee the timely provision of these supplies. Some users in order to yield to the temptation of cheap, from a number of small factories at low price laser engraver, half a year later, laser engraver laser need to be replaced, and a contact manufacturers and found empty.
2) the quality of products
As the saying goes, to watch outsiders, insiders see Road. The same is a laser engraver, but the same parts and components used, the following examples:
a) stepper motor: the relationship of sculpture to the precision laser engraver, some manufacturers choose to import the stepper motor, some joint-venture factory of Health of the stepper motor factory, some non-brand-name motor.
b) laser lens: the relationship between the power laser engraver to the size of the lens at the import, domestic lens, the lens inside the domestic use of imported materials was divided into production and the use of two types of domestic materials production, the price gap between the large gap between the use of performance and service life is also very strong.
c) Laser tube: This is the heart of laser engraver. Laser tube as a result of import prices, are generally in a few million, so the majority of Chinese-made laser engraver laser using China-made pipe. Chinese-made laser tube is good and the bad, the price gap. Good laser tube life generally around 3000 hours.
d) Mechanical assembly quality: some manufacturers to reduce costs, the use of a thin shell of metal production machinery, the user generally can not see, but over time, deformation of the rack will affect the accuracy of laser engraver engraving. Laser engraver should be a good framework, the use of high-quality steel welded together and used to produce high-quality cold-rolled steel chassis. When users buy machines to see whether or not to use the framework of the structure and the thickness of metal chassis, intensity can be found in good and bad quality.
3) the functions of the machine:
Some people familiar with the sigh of the laser engraver, laser engraver current configuration has increased so much, the price and drop it in previous years, how gratifying it. But soon it was said, not by those who dressed??external things, if
Compared to the reliability and maintenance services to facilitate cost-effective, many new devices are smaller than in previous years, the “third kind” of. The author believes that users should pay more attention to the cost-effective laser engraver, “Medium configuration affordable” laser engraver of this is the best choice. Into a lot of user errors, I hope to buy their own laser engraver is “versatile” and what can be done and can do everything, which is significantly wrong. Laser engraver from the purchase of the following uses to explain:
a) carving rubber plate for printing carton:
Most can be used to laser engraver engraving rubber plate, there is no need for you to select those numerous, very fast machine, because the function of those numerous little you can not; carving also do not have access to fast, because carving rubber board speed
Express the depth of the engraving will not be able to meet the printing needs. Recommended: the purchase of suitable rubber plate engraving laser engraver, cheap, fast return of investment.
b) carving crafts:
Most can be used to laser engraver carving handicrafts, in accordance with the requirements of choice:
Bamboo carving, wood, small accessories: Select small machines, such as the size of 300X400, cheap, high precision carved wooden box, wine: Select 500X700, 600×900 size of the machine, and have a take-off and landing platform, or else take a long wooden box do not go.
Carved bamboo, tea tube: Select 500X700, 600×900 size of the machine, and have a take-off and landing platform, and equipped with rotating engraving device.
Large carved wood engraving: 600×900 format options to choose the machines and take-off and landing platform requirements, and can pass the machine before and after the expected, such large-size wood carving can also be easily.
The production of cards: Choose 500X700, 600×900 size of the machine, and have a cutting platform, cutting speed of the machine, otherwise the edge of paper painted yellow.
c) acrylic cutting board
Most laser engraver can be used to cut acrylic plate, but my recommendation is to choose a dedicated laser cutting machine, for laser cutting machine laser cutting for optimized design, cutting a very good effect. If you still insist on enough to buy an ordinary laser engraver, a choice that must have a “knife-bed” installation laser engraver. Remember: Do not believe what some manufacturers say 60w, 80w machine can cut 20mm thick acrylic, this is impossible, even if we manage to cut through, it is appalling the cutting edge. Normal values:
60w of the laser engraver can cut the 8-10mm Acrylic, 80w of the laser engraver can cut Acrylic of 8-15mm.
d) clothing, leather carved cutting
Choice of cutting speed, and a cellular platform cutting laser engraver.
