What factors lead to the instability of [UVLED curing equipment]? Among the various performance parameters of UVLED curing machines, stability is a very important one. If a [UVLED curing machine] does not have good stability, problems will frequently occur during use, which will inevitably affect production efficiency and defective rate. As a UVLED curing machine manufacturer, we pay great attention to stability when developing and producing UVLED curing machines. If you have purchased a UVLED curing machine of other brands and the equipment has poor stability, it may be caused by the following reasons: 1. Insufficient experience in heat dissipation design. The ultraviolet LED lamp beads selected by the UVLED curing machine are not well designed for heat dissipation. The assembly process and incoming material deviations cause the lamp beads to overheat, the forward voltage drop is out of control, and the actual power deviates from the lower limit. 2. Insufficient power control. The thermal stability of the UVLED curing machine driving power supply is poor, and the temperature difference is large, which directly leads to a large range of power deviations. When the use environment is slightly harsh, circuit failures are likely to occur. 3. The factory deceives customers with low prices. In order to reduce the procurement cost of LED lamp beads, they were not selected according to the design requirements, resulting in the actual power consumption of the LED deviating from the design value. In order to obtain customer orders at a low price, some manufacturers sacrifice the quality of their products. In the selection of LED lamp beads, they choose cheap and cheaper as the purpose, which leads to the continuous failure rate after customers use them for a period of time. 4. The factory selects materials at a low price and makes them roughly. In order to reduce the cost of the control power supply, the selected driving power supply has low constant current accuracy and is unstable, and cannot adapt to the frequency conversion of various lamp beads. 5. The factory's quality inspection is not in place. Under cost pressure, the production process cuts corners and omits the necessary product quality inspection process. Unqualified products are not eliminated in the factory, but flow into the market.
