Evosys Laser GmbH develops and manufactures tailor-made systems for laser welding of plastics that are distributed in the UK by TLM Laser.
Evosys recently started offering a new, patented welding process that leads to a significant increase in efficiency. With so-called Advanced Quasi-Simultaneous Welding (AQW), selected plastics can be processed even more economically.
Numerous test series have shown that welding times can be significantly reduced in some cases. The process makes use of the absorption properties of the plastics and combines two different wavelengths that are alternately guided over the welding zone in a controllable pattern. Experience with Advanced Quasi-Simultaneous Welding shows an improvement in process time compared to the standard process with only one laser source.
The new process can be applied to materials such as PC, but other common plastics are also conceivable in the future. Parallel to the patent granting process, the necessary system technology for the AQW process was developed and optimized for series use. “Our customers can test the process extensively in our Technical Center at any time and use it later for their series production,” explains Frank Brunnecker, managing partner of Evosys Laser GmbH.
