Versatile use Applications in laser welding of plastics are versatile and can be found in various industries. Whether small, narrow weld seams or large-area welds – weld seams produced with the laser are visually appealing and are often integrated into the design of a component. The process has become particularly established for components that required reproducible weld seam properties, such as a hermetic seal for fluidic components. Mobility Mobility is the headline of individual freedom of movement. Whether by automobile, plane, train or bicycle. Laser welding of plastics is used...

Laser welding of plastics is the preferred method in medical technology for applications with high safety and hygiene requirements. This is because laser welding produces contamination-free and reliable joints. Many electronic components are protected from environmental influences by a plastic housing. Sealing with laser beams has established itself in various applications.

Customized solutions 1 | Consulting 5 | ervice S and support 2 | Welding tests Leister provides its customers with comprehensive and competent support in evaluating the optimum welding process for specific applications. Proposals for material selection, support in component design through to the selection of the welding process are the first steps, which are checked by welding tests in one of our application centers. Only then is the implementation discussed. Of course, we also accompany our customers during installation and after delivery through one of our service centers.

Suitable material Functional design The right choice of material is also crucial for the success of laser welding of plastics. In numerous tests with different materials, we have developed a welding matrix and published it on the Leister homepage: Weldable materials with laser. The design of the welding zone is subject to general and process-related guidelines for laser welding of plastics. Depending on the application, these can be requested from Leister.
