The recent years have seen a co ntinuously increasing demand for light-weight compo nents made of polymers. For this reason fusing of polymers in complete system solutions with diode lasers has become more and more im portant. ROFIN already covers a co nsiderable 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 functio nal kit co nsisting 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 co ntrol software for the joining process has been specially developed for polymer welding applications e.g. to deliver a setting signal and level for process co ntrol and quality assurance. Data can be logged for process statistics and quality management.

ba sed on state-of-the-art components

The polymer welding solution is ba sed 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 co ntrol allows for a co nstant welding temperature and hence optimized results.

The most flexible platform for challenging applications

With the recently extended MPS family, co nsisting now of the MPS Compact, MPS Flexible, MPS Rotary and MPS Advanced, ROFIN looks forward to creating truly outstanding solutions for challenging polymer laser welding applications in the near future.
