Laser welding is a technology that has revolutionized the way plastic parts are assembled in the plastics industry. It offers several advantages over traditional welding methods, including high precision, speed, and minimal damage to the surrounding material. The following are some of the ways laser welding is used in the plastics industry:
1. Joining plastic parts: Laser welding can be used to join plastic parts together, creating a strong and durable joint. This method is especially useful for complex parts with intricate shapes or small features that cannot be easily joined using traditional welding methods.
2. Sealing plastic parts: Laser welding can also be used to create a hermetic seal between plastic parts, preventing the ingress of liquids or gases. This is particularly useful in applications where the plastic parts are exposed to harsh conditions or require a high degree of cleanliness.
3. Cutting plastic parts: With laser technology, plastic parts can be cut with high precision and minimal damage to the surrounding material. This is useful for making customized shapes or cutting parts from larger sheets or blocks of plastic.
4. Marking plastic parts: Laser technology can also be used to mark or engrave plastic parts with text, logos or other designs. This is a precise and permanent marking method that can be used for branding, labeling, or identification purposes.
All in all, laser welding technology has become an essential tool for the plastics industry, allowing manufacturers to create complex and durable plastic parts with high precision and speed. The technology is also environmentally friendly, producing little waste and emissions compared to traditional welding methods.
Laser welding at Plastima
Nowadays, plastic is everywhere: on supermarket shelves, in cars, in medical technology, in toys, in furniture, etc. In all these areas, plastic parts are joined together. If this process has to be, particularly high-quality, reliable, and stress-free, laser welding of plastics is the universal procedure of choice.
This is where LPKF comes in. Particularly in our three core industries - automotive, medical technology, and consumer electronics - we know this field like the back of our hand. We benefit from our knowledge of the standards, regulations, requirements, and challenges in various industries by applying our extensive expertise in laser plastic welding in a targeted way.
Standalone machinesLPKF's PowerWeld machines are "standalone" and available in different sizes. The sizes of the systems are in line with the clampable area of the product and the multiplicity. The dual-clamp system combined with the scanner shifter allows even two products to be welded in one process in the larger systems without sacrificing traceability.
PowerWeld 2×00 series, Compact solution for small/medium-sized products
TwinWeld 3D 6000 series, Patented hybrid welding enables stress-free contouring for complex 3D products.
PowerWeld 6600 series, Economical batch production for larger components using servo clamping technology
PowerWeld 3D 8000 series, High performance and quality for large 3D plastic parts.
LPKF's InlineWeld machines are set up for automation solutions and are available in different sizes. The size of the systems are in line with the clampable area of the product and the multiplicity. The dual-clamp system combined with the scanner shifter allows even two products to be welded in one process in the larger systems without sacrificing traceability.

InlineWeld 6×00 series, Economical series production for medium and larger components universal machine for easy integration
For plastic laser welding, the transparency of materials is crucial. This is measured with the TMG 3 from LKPF.
Since LPKF's TMG 3 is set to 980nm wavelength, it measures with the same wavelength as absorption laser welding systems. This makes it easy to check inline or offline whether the materials to be used are suitable for the laser weld joint. The TMG 3 can therefore be used perfectly for quality purposes.
The cooperation between LPKF & Plastima has stood for more than 10 years!
