When to Replace a Module

One of the most commonly replaced items on any hot melt packaging line is the module. Typically confused with an applicator gun head, the module attaches to the front of the applicator gun and dispenses the glue through the nozzle and onto the applicable surface. If you are experiencing clogging issues with your hot melt line or dripping from the tip of the nozzle, most likely the module has reached it’s end of life and needs to be replaced.

Replacing a module is fairly simple. First make sure the air is disconnected from the applicator. Always wear Kevlar gloves and eye protection when replacing any parts on your active hot melt system. The parts get hot and extending downtime might not be an option, so operator safety is very important. Then, remove the front two screws from the module and pull the module off the surface of the gun manifold. Make sure that you use the new o-rings and screws that come in your new module replacement kit. This will ensure that the new seal is tight and will not leak once operations restart. Also, make sure you are replacing the existing module with the correct replacement module. Below is a list of module options:

Finally, we also recommend to put a new nozzle on every new module. This will ensure that no clogging will occur. If you have a zero cavity or ProBead module, then the nozzle will already be attached.

Zero Cavity Modules and What They Are Used For

There are several different set ups available for your hot melt application. That’s because not all industries use glue application for the same reason. The most common form of hot glue application is standard case packers for mass production high speed packaging. Typically, those lines use standard H200 modules. However, glue application is used to seal other, more specific products. For example, swirl pattern modules are used for glue application on feminine hygiene products, diapers and also for sealing air filters. This blog is going to specifically explain zero cavity modules and what industries use them and why.

Zero cavity modules have a very specific look, with a nozzle head attachment rather than a screw on nozzle. They also come with an E-Z Micro Adjust attachment to manage precision glue application. This nozzle & micro-adjust feature is custom manufactured for precise glue placement on smaller boxes, such as crayon boxes or pharmaceutical products. This unique technology allows for line operators to place a small amount of glue on a small, predetermined location without creating any stringing. Typically, because of this precise requirement, most zero cavity modules are made with either a .008 or a .012 diameter orifice, so that there can never be too much glue applied.

Because zero cavities have a matched piston needle and seat, when they finally wear out, most manufacturers require customers to replace the entire module. Universal Systems does not. We manufacture a rebuild kit specifically for zero cavity modules for a fraction of the price of replacing an entire module. Check out our rebuild kits here: https://www.ussefl.com/products/hot-melt-modules/module-rebuild-kits/.

Not many hot melt application manufacturers offer zero-cavity modules. Luckily, here at Universal Systems we have been manufacturing this specific module for over 25 years.

Hot Melt Equipment Compatibility

Most all packaging lines come with an already installed hot melt adhesive system. This is the entire system that melts the adhesive pellets and transfers that adhesive to the boxes before they are sealed.

It is important to know that just because your packaging line comes with a hot melt system, that does not mean you need to buy the exact brand name replacement parts. Universal Systems SE manufactures an array of hot melt components and equipment at economical prices, that are most likely compatible with your current system.

The key term to focus on is compatibility. The devices and parts used to construct an applicator system are in depth, and we know they can get confusing. Not only do you need the melter itself, but you also need applicator gun heads, modules, nozzles, hoses and pumps.

Choosing the right part, or replacement part, to best fit your company’s needs may be difficult. Universal Systems SE has tried to make this process easier by building our technology to be compatible with all of our largest competitors. We also offer online search capabilities and list all cross-reference part numbers on our website, so that you can match your current part with our Universal Systems part number. This helps to eliminate confusion when ordering replacement components.

Example Cross-Reference Compatibility Comparisons:

ProBilt™ 20 Melter – Compatible to Nordson® P10, 3500 Series, 2300 Series

ClearFlow™ Hoses 4100 Series – Compatible to Nordson® 107286, 107287, 107288, 107289, 107310, 104008, 223838, 100832
