Insulation materials

KRAFT is a leading manufacturer of machines and plants for processing insulation materials.

In the field of insulation materials, they process for example polyurethane (PUR/PIR), sandwich elements with metallic and flexible protective layers, XPS, EPS and mineral wool.  In times in which due to energy conservation and environmental protection more and more demands are made regarding heat insulation, these products have become an indispensable and future-oriented material.

With our expertise and decades of experience and innovation, KRAFT offers the optimum solution for every application (conveying, sawing, trimming, profiling, machining, storing).
Individual and customer-specific special solutions complete the range of services offered by KRAFT.

Our automation team develops efficient control systems based on Beckhoff or Siemens, according to the respective customer-specific requirements.  Customized concepts provide a considerable increase in productivity and quality for the future.

Host computer systems ensure a process-optimized data exchange between your ERP system and the KRAFT machinery and plant control systems.

Application example

The endless strand of the element coming from the sandwich plate conveyor is divided into motherboards via diagonal saws and passed to the cooling and hardening section via roller and belt conveyors.

The cooling and hardening section, executed as a space-saving paternoster system (as option as horizontal cooling section), ensures steady dimensions of the insulation panel, which is subsequently passed on for further processing.

The longitudinal edges are processed in throughfeed with tongue/groove, a shiplap or a smooth contour via longitudinal profiling equipment.

In the cutting saw, the motherboards are cut to pre-defined, small formats and fed to the cross-profiling.  Optionally, the insulation panels can also be provided with tongue/groove, shiplap or smooth contour in the cross direction.

Conveyors transport the processed insulation panels to an accumulation station and align them.

A stack gantry creates packages from the insulation panels.  These packages pass through the shrink wrap tunnel and are packed according to customer’s requirements.

By means of a package stacker, the packages can be offset crosswise depending on the format, stacked up to a height of 2,400 mm and passed on to the finished parts storage.
