When many companies encounter bottlenecks in development and encounter difficulties, they choose to use second-hand laser marking machines. In fact, this is a very unsafe place for the machine. Not only others use it, but also various unexpected problems will occur. It doesn't exist either. Let's analyze whether or not to buy a second-hand laser marking machine.
First of all, the after-sales service of second-hand marking machines is not guaranteed. After a problem occurs, the seller will not provide you with after-sales service, and the manufacturer will not provide you with after-sales service. Many manufacturers will only buy their machines directly, and buyers will provide after-sales service, so this One needs to be very careful. Some people also say that second-hand laser marking machines will work well after a period of running-in, after all, these are only a few. This issue requires special attention.
Therefore, it is still very risky to buy a second-hand laser marking machine, so everyone should not buy second-hand when economic conditions permit, but should choose a regular laser marking machine manufacturer to buy. This can completely avoid the trouble caused by later construction.
As we all know, the brain of a laser marking machine is the laser, and the loss of the laser also determines the performance of the whole machine. Buying second-hand laser marking opportunities will often find problems. The general laser loss is mainly due to the defects of the quartz glass itself and the metal transition impurities, which affect the scattering, absorption and dispersion of light during the transmission process. Generally, it is divided into scattering loss, absorption loss and dispersion loss.
