Laser Plastic Welding

Process reliability
for medical technology

Laser plastic welding provides safety and reliability

Traceable processes, cleanliness in the application

We are big on process reliability and quality assurance LPKF makes it possible to ensure traceability and accurate reproducibility in processes. After all, we know that the adherence to specific cleanliness conditions and process validation are important factors in the production of plastic components in medical technology.

Application examples for medical technology

Clean, fast, flexible, reliable, and suitable for clean rooms: The LPKF laser systems for plastic welding make it possible to produce safe, hygienic, and hermetically sealed joints between plastic components – without (chemical) additives, foreign bodies, or particle contamination and with only slight mechanical component strain. For example, this technology is used when joining plastic housings or geometric bodies and in microfluidics.

Cylindrical bodies

Small to large cylindrical bodies made of plastic are joined by means of a laser in a radial welding procedure: catheters, valves, pins.

Cartridges

Precise execution of fine channel geometries – for perfect diagnostic results without swirls, additives, or particles

Housings

Laser-welded housings – truly impermeable with hygienically impeccable joints and a corresponding appearance

Transparent parts

Transparent plastic components joined by laser – for microfluidics or for components that are transparent for aesthetic or functional reasons

Process reliability and quality assurance

LPKF laser systems secure the process chain

Quality and profitability are ensured through flexible production options, material-preserving processing, hygienic and high-precision process sequences, and the traceability of all process steps. LPKF systems allow for integration in existing manufacturing execution systems through standardized electrical and mechanical interfaces – including with regard to Industry 4.0 integration.

And what is the weld seam like?

  • Weld seam widths in the micrometer range
  • Absolutely impermeable seams
  • Particle-free result
  • Extremely fine and visually appealing seam structures

Continuous process monitoring and process control – conveniently provided through the user’s superordinate, central control system – guarantee quality assurance. The welding process can be documented for each individual component using multiple testing procedures.

 In addition, the systems can also be equipped as versions suitable for clean rooms and integrated in production lines.
