"We build and upgrade
machinery almost limitlessly"

In the printing and packaging industry, the number of existing systems that are no longer in line with new demands and requirements is increasing. System availability and maintenance-friendliness play an important role in this. The demanded product range and state-of-the-art quality standards cannot be fulfilled by all existing systems. Yet, it is important to remain competitive and secure a strategic advantage.

Crucial factors in this are high product quality, short set-up times, minor waste and easy operation. Completely replacing existing machinery is often too expensive.

In HL Engineering, you have found a partner aiming for top performance. We aim to increase the availability and performance of your machinery as well as extending your product range. Based on our comprehensive process knowledge, we feature complete solutions from the first idea to project completion.
