Choosing the Right Adhesive and Epoxy Dispensing Machine for Specific Applications

An adhesive dispensing machine can be an integral part of many manufacturing processes. They provide a precise and metered application of adhesives, epoxies, or other compounds to parts and assemblies. Automating these tasks with adhesive dispensing equipment is essential to making many processes viable, and such adhesive and epoxy dispensing systems have become widespread across electronics manufacturing and other industries.

Dispensing Machines for Different Types of Compounds

Within the category of adhesives, epoxies, and similar compounds, there is a wide variety of choices. The manufacturers who develop dispense systems must cater to this variety, providing equipment that can handle many different types of components.

Among the most important distinctions for dispense systems is that between one-part and two-part adhesives. Some adhesives, like silicone, are simply applied as an individual component. However, epoxies and similar compounds require two parts. The epoxy resin must be combined with a hardener in order to cure.

This process must be carried out at the time of application, so any epoxy dispensing systems must have the capability to handle two-part compounds. Many systems will have multiple modes of operations that allow for both one-part and two-part applications. Some even include multi-component capabilities beyond that, allowing for a mixture of many components at the time of application.

Automated Application With Dispense Systems

Simply having the ability to move adhesives from a drum to a part isn’t enough for modern applications. Adhesive dispensing equipment must also have the capabilities to carry out the precise and accurate application. Parts and assemblies will all have their own unique shapes and sizes. Today, robotic systems incorporated into this equipment make it possible to apply compounds in any form, arrangement, or quantity.

Manufacturing across different sectors can have a variety of unique application requirements. Effective equipment must be able to meet these needs. Adhesives, epoxies, sealants, and more could be applied in the form of beads, dots, in-filling, gaskets, or potting. The versatility and precision required are key differentiating factors when finding the right adhesive dispensing equipment.

An effective dispensing machine must also be capable of working at the specific scale required. Individual applications can vary widely in what weight of compound must be applied per part and per hour. Epoxy dispensing systems could use a light bead or fill entire assemblies with potting components. Dispense systems must have not only the precision necessary but also compatibility with various feed packages.

Specific Material Considerations

A dispensing machine needs to be properly suited to its specific application. The compounds used can vary widely in their physical and chemical properties. This means there are many factors to take into account when finding the right epoxy dispensing systems. Viscosity is one major factor, as any machine will have design specifications dictating a specific viscosity range.

The mix ratio is also an essential factor. When multi-part compounds are used, many systems can struggle to maintain accuracy and precision at high mix ratios where one component significantly outweighs the other. Considering this and other unique constraints for individual applications is key to ensuring that the right equipment is chosen.
