Innovative surface solutions

The first project was conceptualized in 2017 together with Handl Engineering of Wels for Hasslacher Group’s production site in Stall im Mölltal. This robot-assisted solution is designed for workpieces of dimensions of up to 20 x 3.2 meters and a weight of up to 4 tons.

The panels are attached to the load crossbars with a crane. Due to the spatial conditions, the workpieces are then transported about 60 meters to the coating area. In the infeed buffer, the system scans the shape of the elements without loss of productivity. This way, the spraying programs can be created by taking into account parameters from the ERP system. Two rail-bound robots coat the parts on the front and back side in a fully closed spray booth with controlled air flow. Colors are changed automatically using seven color wheels without loss of time.

After coating, the parts dry in a drying buffer. Finiture’s energy-efficient air drying system “LDP” supports this process. In the dryer, all necessary parameters, such as temperature, air velocity and humidity, can be controlled in order to achieve perfect surfaces.

A workpiece cleaning unit in front of the spray booth, air humidification inside the spray booth, an intermediate sanding machine after the dryer and a water treatment plant complete the production line.

Suitable for cross-laminated timber as well

For Hasslacher Group’s glulam production site in Sachsenburg, Handl Engineering will install a coating line for glulam beams in collaboration with Finiture. The solution is based on the technology used in Stall im Mölltal (robots with scanners). In this case, the transport is done with roller conveyors. The system in Sachsenburg can be used to coat small elements as well as glulam beams of up to 27 meters in length and more than 4 tons in weight. When different coating systems are used on one surface, for example on continuous roof beams, colors are changed automatically without loss of time and the need to stop the workpiece.

A workpiece cleaning unit, intermediate sanding machine and dryer complete the line. The production site was also supplied with a master computer system with which elements can be tracked and data can be transferred from the in-house ERP system. The line will be installed in the 4th quarter.

For its new CLT production site in Wiesenau, another Austrian company, i.e. KLH, also opted for a coating line by Finiture / Handl Engineering. A decisive factor in the decision for Handl and Finiture was their experience with large structural elements. The new line is based on technologies which have already been installed and includes an additional special crossbar buffer and a semi-automatic loading and unloading system. The plant is going to be delivered in 2020.
