Temperature control

Sensors for stable heat input

Detect temperature deviations before they adversely affect the component

In plastic welding and laser-based surface processing – such as surface hardening – every degree counts. Differences in material, geometry, or fluctuations in laser power can affect the temperature distribution in the process zone – and thus the result. Our sensor system measures the temperature using a pyrometer in sync with the process and provides the data used to continuously adjust the energy flow. This is particularly crucial in processes such as deposition welding and surface hardening, where heat must be applied with pinpoint accuracy to very small areas.

Temperature control in use

Soldering PCBs

PCBs have tight tolerances during the soldering process. Uncontrolled heat leads to solder evaporation and oxidation – rapid or slow cooling causes warping, cracks, and crystal structure defects. Without temperature control, rejects are inevitable.

The temperature control sensor system regulates heat input precisely and locally. You get clean solder joints without any additional cleaning – and rejects rates will drop significantly. The system flexibly adjusts parameters to accommodate different materials.

Laser surface hardening of gearbox components

Laser surface hardening requires extremely precise temperatures. Temperatures that are too low result in incomplete hardening – temperatures that are too high can cause warping, cracks, or unwanted microstructural changes. To avoid rejects or rework, the temperature is often adjusted manually, which increases production time.

The sensor system continuously measures the surface temperature during the laser process and automatically adjusts the laser power accordingly. This keeps the temperature within the optimal range. This allows you to create stable processes with reproducible results.

Laser surface hardening of bending tools

During laser surface hardening of tools, uncontrolled temperature spikes can occur, leading to deformation and tolerance deviations. This increases wear and reduces the durability of the tools. Manually monitoring the temperature during the production process is time-consuming and expensive.

The sensor system monitors the temperature at critical points in real time and adjusts the laser power accordingly. Predictive data analysis detects overheating in advance. This helps you prevent warping, reduce rework, and increase throughput.

Laser surface hardening of turbine blades

During the hardening process of turbine blades, the energy of the laser beam is often distributed unevenly, depending on the geometry and surface structure. Overheating in one area and rapid cooling in another can lead to warping and cracks, which impair the efficiency of the turbine engine. Without effective monitoring, high-quality results are therefore difficult to reproduce.

The sensor system accurately measures the temperature in the curing zone and automatically adjusts the laser power accordingly. The optimal curing temperature remains constant – the surface is protected, throughput is increased, and quality is ensured to meet the most stringent requirements of the aerospace industry.

Plastic welding of control units

Plastic components such as housings, connectors, and sensors require precise welding temperatures. Temperatures that are too high can cause material deformation and damage – while temperatures that are too low can result in an incomplete bond. Contaminants or variations in the glass fibre content further exacerbate the problem.

The temperature control sensor system continuously measures the temperature in the fusion zone and automatically adjusts the laser power accordingly. Defects and material variations are reliably detected. This helps to achieve tight, high-quality welded joints – consistently and without rejects.
