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.

Combat Downtime

Downtime for an average production line can cost a company, at minimum, between $150 – $170 per minute. This makes it vital for companies to identify factors and equipment that impact production capacity.

Why are Hot Melt Adhesive Systems so important?

Hot melt adhesive systems are often overlooked as just a cog in the production packaging line. However the reality is that these small systems are vital to processes like primary paperboard packaging as well as the key to ensuring protective secondary packaging. Furthermore any disruption to the heating, transferring and adhesive application process results in the slowing if not complete shut down of a production line.

While literal monetary translation of the 1-10-100 principal is debatable, there is no question a proactive approach to maintenance that considers prevention cost, corrective cost and failure cost will reduce downtime and yield significant savings.

How to optimize Hot Melt Part Maintenance and Purchases

To ensure quality, longevity, and support for hot melt glue equipment one should purchase from a well-established manufacturer such as Universal Systems SE, Nordson, Graco, ITW Dynatec or Robatech. All these companies have engineers on staff to discuss equipment selection, technicians to address maintenance questions, and sales representatives who can assist with product procurement and replacement.
