When maintaining high-performance operation of the hot melt adhesive machine, you can take many measures to reduce downtime and improve system performance. Please remember that downtime equals production loss.
1) Apply hot melt adhesive at the correct temperature. Using the correct settings can avoid many troubles. You may also want to try using a metallocene hot melt that can melt very cleanly, reducing accumulation and carbonization.
2) Regularly flushing the hot melt system, including the hot melt hose, not only helps maintain the hot melt equipment, but also extends the service life of the hot melt hose and hot melt gun.
3) There is nothing worse than waiting for parts for a long time to prepare spare parts for the hot melt system. These spare parts include glue gun nozzles, glue gun heating modules, hoses, and air filters. This mainly depends on the frequency of use.
4) Make sure to keep the lid on the hot melt machine closed, as this will eliminate the entry of debris. We open the lid to facilitate frequent addition of hot melt adhesive, but the presence of foreign objects in the system may cause multiple problems, not only with the glue furnace, but also with hoses and glue guns or nozzles.
5) Ensure to minimize idle time as much as possible during work. Long term high temperature without using the machine can lead to scaling and carbonization of the hot melt adhesive machine.
Direct answer: The most secure arrangement for sealing and gluing points is to leave 20-30mm at both ends, evenly distribute in the middle, and cover a total length of about 60% -70% of the sealing length. The common three-point, five point, and strip continuous methods have their own applicable scenarios. Choosing the wrong arrangement not […]
Hot melt adhesive particles are solid adhesives that are heated above their melting point before being applied to a substrate. According to the desired application, hot melt adhesive has various appearances and textures. They do not require a curing or drying period as they quickly solidify when cooled to the freezing point. Therefore, hot melt […]
Under standardized storage, the shelf life of EVA hot melt adhesive granules is usually 12-24 months; Polyolefin and other systems can last longer. But ‘shelf life’ does not mean ‘just leave it at will’, the environment determines the actual usable time. Key factors affecting shelf life Reference for shelf life of different systems system Reference […]
Although EVA hot melt adhesive is an excellent solution for many industrial applications, it requires careful control of the high temperature during the process to avoid smoke problems. When hot melt adhesives are heated, they inevitably release some smoke. That is the odor detected while working near the hot melt nozzle. Although some smoke is […]
