The topic of glue and epoxies and the machines that dispense them are quite closely related, but may be considered distinct as well. The actual glue and epoxy administered through dispense valves, epoxy dispenser pumps, and other fluid dispensing systems are a topic on their own, such as their contents and uses. Meanwhile, interested engineers may consider how these dispensers are made, such as static mixing nozzles, cartridge dispensers, and more. These static mixing nozzles and more are the hardware aspect of glue or epoxy dispensing, and these machines should be in good condition when used. They can be part of a larger machine in a factory, but others may be handheld devices used by home repair experts, carpenters, and more. That includes mounted static mixing nozzles on a glue gun.
Using These Glue Dispensers
What makes for a quality glue or epoxy dispenser? As one example, static mixing nozzles may be used, and these static mixing nozzles come in a variety of models and types, such as EXACT and the like. To put it simply, static mixing nozzles are used to mix and dispense adhesives that come in two separate parts. Often, it is meter mixing machines and adhesive cartridges that make use of static mixing nozzles, and the two separate ingredients cannot be stored together until used. Otherwise, glue or epoxy would form inside the cartridge or dispenser, and that cannot be allowed. They come into contact only during the exact moment of application, and something similar can be said about polyurethane injectors.
Polyurethane injectors also use hardware to keep their ingredients separate, and when plastic good are being made in a factory, they are injected and mixed together to form the final product in its liquid phase in the mold. Often, the machine will use a great deal of pressure, such as over 1,000 psi, as well as heat, to help facilitate this mixture and to help create the final product in the mold.
Either way, these static mixing nozzles are known for being one-time use and they are often low-cost, making them practical for use in a factory or other production site. These nozzles may also make for precise mixing, allowing the compounds to form in exactly the correct ratio to ensure consistency in the products created. This helps a factory maintain quality assurance in anything that it makes, and also helps to minimize any wasted material to further make this process efficient.
What sort of factories might make use of these static mixing nozzles? Car plants often make use of them, as many car parts require sealing to prevent gases or liquids from going where they don’t belong. Automated or handheld static mixing nozzles and dispensers can be found here, and the same is true in a factory producing home appliances. And of course, medical equipment production also involves the use of static mixing nozzles and related dispensers.
Epoxy is easily released with simple handheld dispensers, and these dispensers may not even require electricity at all to function. Rather, the user will place a tube of epoxy in the open slot, then secure it in place and remove the tube’s cap for application. A trigger will force a lever and flat plate forward in the dispenser, using pressure to squeeze out epoxy like an oversized toothpaste bottle. This is a simple and convenient way to dispense epoxy, and an exhausted tube of epoxy can simply be removed and replaced with a fresh one. A user can easily see when a dispenser’s epoxy tube is nearly dry.
