Hot Melt Glue System

A hot melt glue system is a complete adhesive installation: the melter, the pump, the heated hoses, the applicators and the controls that tie them to your production line. Buying the parts is straightforward. Making them work together as one system, at your line speed and on your material, is the part that decides whether the investment pays off.

BIT Hotmelt Technology designs, builds, integrates and services these installations. Since 1982 we have worked on everything from a single application point to fully automated multi-head systems.

From Single Machine to Complete System

A single melter with one gun is a machine. It becomes a system once adhesive application has to be coordinated with everything else on the line: product position, line speed, changeovers, quality checks and alarms.

That coordination is where most of the value sits. A hot melt glue system that compensates for line speed keeps the same bead length whether the line runs at half or full output. Systems that read product position apply adhesive only where a product actually is, instead of spraying into gaps. Systems that monitor tank level and temperature warn an operator before a fault becomes a stop.

Without that layer, you have equipment that works when someone is watching it. With it, you have a process.

What We Integrate

The hot melt glue systems we build are assembled from five layers, each specified around the product rather than the catalogue.

Melting and supply. Tank, grid or drum units sized to your consumption, with automatic filling where refilling has become a task in itself.

Distribution. Heated hoses and manifolds feeding one or many application points, with independent temperature zones so viscosity stays constant across the whole circuit.

Application. Guns, heads, modules and nozzles selected for the pattern the product needs — bead, dot, slot, spray or swirl.

Control. Pattern and timing control, line-speed compensation, level and temperature monitoring, fault alarms and integration with the machine controls you already run.

Reactive adhesives. Where the process calls for PUR, the system is built sealed and moisture-free, with dedicated circuits and a purging routine.

Retrofit or New Build

Not every project is a new line. A large share of the hot melt glue systems we deliver are retrofits: an existing machine that needs a second application point, an ageing unit replaced without touching the rest of the line, or a manual gluing station converted to automatic application with a mounted applicator and a sensor trigger.

Retrofits are usually the fastest route to a measurable result, because the surrounding line already works. The questions are mechanical mounting, trigger signal and adhesive choice — not a redesign.

How a Project Runs

We start with the product, not the equipment. What is being bonded, on which materials, at what speed, in what environment, and what does the bond have to survive.

Then we test. In our test centre we run your product with candidate adhesives on production equipment. You see the bead, pull the bond apart and see the consumption before a specification is written.

Then we specify and build. Melter capacity, number of outlets, applicator type, nozzles and control logic, sized with headroom for the growth you expect.

Then we install and hand over. Including operator instruction, because the best-specified system still fails if nobody knows the purging routine or the temperature settings.

And we stay. Preventive maintenance, spare parts, workshop repairs and service on site.

Where They Are Used

Hot melt glue systems run in packaging and carton sealing, labelling and end-of-line automation, furniture and panel production, filter manufacturing, automotive components, mattress and textile production, and electronics assembly. The principle is the same everywhere; the configuration is not, which is why we specify each one from the product backwards.
