Our patented cera2heat® matrix heating system enables heterogeneous, precisely defined contact heating of surfaces.

Each of the regularly arranged, small heating pixels, with independent temperature settings, can be individually programmed and controlled. Similar to a TFT screen, the precise temperature of the heating pixels can be visually projected as a thermal image.

The heating system consists of 4 x 4 cm (1,57 x 1,57 inches) modules that can be arranged in arrays and combined to form individual surfaces. Due to this modular design, cera2heat® can be integrated or retrofitted to almost any machine.

Our heating system cera2seal® is specifically designed for sealing and welding processes.

For the first time, complicated packaging geometries can be implemented – including complex irregular shapes. Additionally, our heating system allows for the combination of varying sized rings and sealing bars.

Customized arrangements of individual heating circuits combined with integrated temperature sensors are the key behind this innovative seal heating system, allowing for precise control of the temperature distribution.

For exceptional and particularly demanding applications, we also offer individualized, tailor-made heating systems based on cera2seal® and cera2heat® technology.

From planning to implementation, we support you through the entire process to ensure you have the right application:

• Optimal temperature distribution through finite element calculations
• A heating layout suitable for your application
• Manufacturing of individual heaters for small or large series production
• Control and regulation electronics, fully integrated solution with minimal space requirements

Many technical parameters of the heating system can be individually adjusted to meet your needs:

• Surface to be heated
• Temperature and power distribution
• Dimensions
• Heating output
• Maximum temperature
• Heat-up rate

By using market-leading simulation software in conjunction with our own toolboxes, we simulate the performance of product layouts, as well as predict the influence of various external factors.

• Simulation of thermoforming processes: we determine the optimal temperature profile for the selected shape and material combination to achieve the best possible material distribution.
• Simulation of top load pressure behavior: we optimize the material distribution for all shapes, with regards to a given mechanical load, in order to comply with process requirements e.g. top load pressure limits.
