Laser Welding

Laser welding simplifies the production process


Medical devices with complex assembly operations, for example, hoses and valve functions can have high failure rate during the assembly and service.

To minimize the risk when developing a new medical device, designers often choose well-known, proven construction methods and solutions. However, gluing processes require processing time in production and at the same time they are harder to control and requires special measures like exhaustion and process surveillance. Ultrasonic welding can be difficult to control and is suitable primarily for simple assemblies. Use of new and innovative methods of assembly requires a convincing cost benefit and a convincing case story.

Laser welding of plastics has been used by Technolution since 2006, but is still unknown to most plastic constructors.


Laser welding of plastic parts is a simple, fast and stable process

  • Reduces errors during assembly and service
  • Reduces assembly time
  • Increases reproducibility

Plastic components can be joined to units that replaces complex, time-consuming assembly work. More features can be integrated – for instance fluid transport, valve functions, connections, construction elements, …

Laser welding requires investment in process equipment, but the ROI is ensured through shorter process time, reduction of errors and a stable quality. Manufacturers of laser welding equipment offers laser welding of components and therefore the company can avoid or postpone investment in process equipment.


The development work is carried out close cooperation with the clients’ development and production team.

Technolution participated in the entire process from concept development and design of devices, identification and procurement of laser welding tools, design of jigs and production of the finished devices.
