Durham Box Upgrades Gluing With Baumer hhs Xtend3

Durham Box, a UK corrugated packaging manufacturer, has upgraded its gluing operations with a combination of cold glue and hot melt systems from Baumer hhs. The November 4 case study details how the converter moved from Xtend2 to Xtend3 controllers and replaced a hot melt unit on its e-commerce packaging line with an Xmelt system. For Kylin readers, the story is useful not because it announces a single machine, but because it shows how a converter treats glue application as a quality and uptime problem, not just a consumables cost.

Why Gluing Is a Control Problem, Not a Cost Problem

Corrugated converters operate in a price-competitive segment where a single defective batch can erase the margin on a large order. Glue application sits at the center of that risk: too little glue and the box fails, too much and it slows production and creates waste. Durham Box frames its investment as a way to make gluing processes “stable and reliable” while increasing line availability. The takeaway for any packaging producer is that the controller and the sensor matter as much as the glue itself.

The Xtend3 Upgrade

Durham Box has used Baumer hhs equipment for more than ten years. In early 2026 it moved its Xtend2 controllers to the Xtend3 generation across its gluing lines. The new controllers act as the central unit for both cold glue and hot melt application, combining gluing control with quality monitoring in a single interface. Durham Box cites intuitive operation as a reason the controllers support stable processes, and highlights their reporting functions for analyzing process data and making ongoing improvements.

Cold Glue on Folder Gluers

Two folder gluers and one multipoint gluer are equipped with four Xcold cold glue systems from Baumer hhs. Each is a complete system made up of high-performance application valves and quality control sensors. The company says it replaced equipment from other suppliers with these systems when it first partnered with Baumer hhs, and has kept them through the latest update because they perform reliably at high production speeds.

The Xmelt Hot Melt System for E-Commerce Packaging

The most concrete change in the case study is on the e-commerce packaging line, where Durham Box replaced an existing hot melt unit with an Xmelt system built for that application. The system is built around an XM-100 FC melter with a 100 kg tank capacity and a high melt rate, which the company says supports non-stop production. An HLT-300 hot melt sensor continuously monitors the adhesive to confirm it is applied to each box blank to specification.

Why the HLT-300 Sensor Matters

The HLT-300 does more than detect the presence of glue. It checks temperature and the properties of the pressure-sensitive adhesive to verify that the surface of the glue beads is uniformly closed and that the packaging will reseal properly. For e-commerce boxes, resealability is a functional requirement, not a cosmetic one. A sensor that confirms the glue bead is closed and resealable moves quality checking from a post-production sample to the process itself.

What the Numbers Do and Do Not Say

Durham Box reports that the new equipment has increased the availability of its gluing lines “by several hundred hours a year” and that the number of customer complaints has dropped since installation. These are directional results from a single customer case study, not independent benchmarks. The release does not provide before-and-after defect rates, glue consumption figures, or a payback period. Converters should read the results as evidence that controller and sensor upgrades can move the needle on uptime and quality, while validating the specifics against their own line conditions.

Three Checks Before Upgrading a Gluing Line

• Controller coverage. Confirm the controller can run both cold glue and hot melt, and that it exposes the process data you need to analyze, not just a black-box setting.
• Sensor function. Ask whether the sensor only detects glue presence or actually verifies bead closure, temperature, and resealability for your specific adhesive.
• Application fit. Match the melter and valve to your throughput and adhesive type. A 100 kg tank and high melt rate support long runs, but may be over-specified for short, varied jobs.

Cold Glue vs. Hot Melt: The Right Tool for the Job

Durham Box runs both, and the case study illustrates why. Cold glue systems on the folder gluers handle the structural bonding where the adhesive has time to set, while the Xmelt hot melt system handles the e-commerce line where resealable closures and fast set are priorities. The two technologies are not competing; they solve different problems on different parts of the floor. Converters choosing gluing equipment should map their own product mix to adhesive types before specifying machinery, rather than defaulting to one technology across all lines.

What This Means for Kylin Readers

Kylin’s gluing equipment sits on the same principle: stable, controllable glue application is what separates a reliable packaging line from one that produces intermittent defects. The Durham Box story reinforces that the controller and the monitoring sensor are as important as the application hardware. A well-specified gluing system should give operators visibility into what is being applied and confidence that every blank meets the spec, whether the adhesive is cold glue or hot melt.

For converters building or upgrading a gluing station, the lesson is to evaluate the complete system, control, valve, sensor, and reporting, rather than the melter or tank alone. The goal is not simply to apply glue, but to apply it consistently and verifiably across every job.

FAQ

What did Durham Box upgrade? It moved from Xtend2 to Xtend3 controllers and replaced a hot melt unit on its e-commerce line with a Baumer hhs Xmelt system.

What is the Xmelt system built around? An XM-100 FC melter with a 100 kg tank and high melt rate, plus an HLT-300 hot melt sensor for continuous adhesive monitoring.

How many cold glue systems does Durham Box run? Four Xcold systems across two folder gluers and one multipoint gluer.

What results does the company report? Increased line availability of several hundred hours a year and a drop in customer complaints, described as single-customer results rather than independent benchmarks.

Turning the Signal Into a Gluing Decision

The Durham Box case study is a reminder that gluing is a control problem as much as a chemistry problem. Converters who treat the controller and sensor as an afterthought leave uptime and quality on the table. Those who specify the complete system, and verify it against their own adhesives and product mix, gain a more stable and measurable production process.
