In the process of using the high speed injection type glue dispenser, the problem will be caused by various reasons. For example: epoxy, the sealing problem caused by glue curing, and curing the bubble. These conditions often perplex the application manufacturers. Therefore, when choosing high-speed dispensing machine, do not only care about the high cost of purchase. As the saying goes, "a penny and a piece of goods", we must choose a high speed sprayed dispenser with good reputation. The situation is causing the most glue seal problem, because the price is cheaper, the quality of dispensing machine is also a serious problem, leading to a design flaw or the durable. Tight seal, material bucket and pipeline and other aspects, seemingly complex pipelines, specific glue to select a special feeding tube and so on. There are usually two reasons for the poor curing, one, the precision of the proportion of glue is not enough. Two, the mixing effect is not good. Therefore, the precision of the metering pump is very important. There are two ways of static and static mixing. As for which way to choose, it should also be determined according to the practical nature of glue.
