Munich/Germany, July 30, 2015: ROFIN continues the MPS laser workstation success. Its wide range of applications is extended by fusing of polymers. The system is based on the market-leading MPS laser workstation and the DILAS Compact Evolution laser sources and comes with application-specific control software.

The recent years have seen a continuously increasing demand for light-weight components made of polymers. For this reason fusing of polymers in complete system solutions with diode lasers has become more and more important. ROFIN already covers a considerable share of this expanding market with its DILAS diode lasers. However, more and more customers are asking for complete laser polymer welding solutions.

Goal-driven development

The polymer welding system is either sold as a turnkey machine or as a functional kit consisting of laser, clamping unit and software for process control. Within less than a year the new polymer welding solutions are already turning out to be a great success.

HMI and clamping specifically designed for polymer welding

The systems are equipped with a special human machine interface for polymer welding and a work piece clamping unit working with either a pneumatic or a servo clamping drive, manufactured to the customer’s specific requirements. The control software for the joining process has been specially developed for polymer welding applications e.g. to deliver a setting signal and level for process control and quality assurance. Data can be logged for process statistics and quality management.

Based on state-of-the-art components

The polymer welding solution is based on ROFIN’s MPS, a production proven, multi-purpose laser workstation with a multitude of installations worldwide. It houses a DILAS Compact Evolution laser, operating with 980 nm or 880 nm wavelength and a cw power of 150 – 500W. A pyrometric process control allows for a constant welding temperature and hence optimized results.
