The challenge
Developping a customized solution
At Meler we meet our customers’ needs and adapt our designs to fit them. To give you an example, we would like to tell you about a solution that we designed for one of our customers, mainly engaged in the production of insulation panels in the construction industry. The difficulty that we faced was that we needed to develop an application that was capable of affixing the layers that make up those panels in a way that was completely accurate, effective and cost-effective way.
Our contribution
What is Meler’s multi-module cold glue application head like?
The cold glue application head has compatible modules that are arranged linearly, all of which can be individually adjusted for grammage control.
Furthermore, it has pilot-operated electrovalves that allow the customer to adjust the application width, a feed air distributor for the electrovalves and another for the modules’ air outlet. They ensure that the Meler cold glue application head offers maximum precision for the application of dots and beads without touching the surface or substrate.
A water dispensing system allows the modules that are currently inactive or are not going to be used for the application to remain submerged. This prevents the cold glue from drying when it comes into contact with air and, therefore, blocking the modules.
The Meler cold glue application head has four inlets for adhesive and a cut-off valve for the water, making it easy to clean. It also has an adhesive tank that is supplied from a higher-capacity tank.
The project (duration, destination, sector)
The advantages of Meler’s cold-glue multi-module applicator
-
- Aplicación muy precisa con una distribución homogénea: gracias a un gran canal de distribución, la presión queda repartida de manera uniforme a lo largo de todo el aplicador, lo que hace que siempre se emplee la misma cantidad de adhesivo en cada punto.
- Highly accurate application with an even distribution: thanks to its large distribution channel, the pressure is applied evenly along the entire applicator, meaning that the same amount of adhesive is always used in each dot.
- Simultaneous application of hot-melt glue to hold the two pieces together while the product is being handled and the cold glue is in the drying period.
- The intermediate adhesive tank, located between the head and the higher-capacity tank, has a level detector.
Impact
- Adjustable to the user’s needs
- Possibility of simultaneous production processes
- Autonomous control of application parameters
