Current State of Laser Technology in Production

Lasers have become a widely adopted tool in various production sectors due to their high precision, well-controlled local energy application, and the cleanliness they provide during processes. As a result, lasers have established a significant presence in the manufacturing industry.

At EVOSYS, our expertise lies in laser plastic welding, laser soldering, and micrometal welding for the automotive, medical technology (medtech), and consumer goods sectors. Our focus on these applications enables us to deliver optimal solutions tailored to your needs. A commonality among these applications is the fundamental system technology requirements, which ensure the most cost-effective solutions over the long term.

In the automotive industry, applications include the production of sensor and fluidic components, as well as assemblies for interior and design elements in vehicle bodywork. In the fields of medical technology and pharmaceuticals, lasers facilitate the hygienic production of devices and consumables. Furthermore, in the consumer sector, lasers can be applied in a variety of contexts, such as the manufacturing of components for smartphones, printers, and other everyday devices.

Benefits

Laser welding of plastic has been an integral part of production in the automotive industry for more than 20 years. In addition to its flexibility, the industry appreciates that plastic welding has the following characteristics. It is
fast

clean

process-safe

economical
Example of application

Cover welding of a gearbox

The assembly shown in the picture, made of PA6 GF30 natural/black, is joined by means of quasi-simultaneous welding. The laser welding process must be as economical as possible and reliably achieve a seal of the IP6K7 category.

Due to the customer’s flexible production concept, which works with a belt transfer system, a solution based on our process modules was developed. The EVO 3800 is completely integrated, ensures laser class 1 and is equipped with all necessary communication interfaces. The process setup as well as any necessary adjustments are conveniently implemented with the EvoLaP process software.

Medtech
Secure and reliable

Due to the constant development of new treatment methods, the importance of reliable production processes in the healthcare sector is rapidly increasing. We support you with our engineers and their many years of experience in the field from the very first development steps for new products and associated joining tasks right through to the complete solution for your production. Absolute reliability, complete documentation and the implementation of the highest cleanliness requirements are always in the foreground. Laser welding of plastics is the ideal process to meet these requirements. Production according to GMP standards is easy to ensure with EVOSYS equipment.

Predestined for innovative medical devices

Laser welding of plastics is established as a safe joining process. Our EVOSYS specialists always find the optimal solutions for new products. In addition to flexibility, the industry appreciates that plastic welding has the following characteristics. It is
- clean and particle-free
- free from additives
- reliable
- suitable for the clean room
Example of application

Clear-transparent welded joint

Laser welding with a wavelength of 2µm is particularly exciting for medical products. This can be used, for example, to process assemblies as shown in the picture. The big advantage: no additive is required! The process can be used with many common materials (PP, MABS, COC). For the production of very high quantities, the EVO 0800 integration systems are particularly suitable. They can be used in all standard automation solutions. Their advantage lies in easy integration and online process monitoring.

Consumer
Fast and cost-efficient

Miniaturization, design and extreme packing density are the most common requirements we encounter in the field of consumer products. We provide support at an early stage with our process and production expertise. This means that targets can usually be exceeded. But laser welding of plastic can also be the best option for everyday products. Systems from EVOSYS are always the best choice.

Plus points from A to Z

Laser welding of plastic is ideal for almost all joining tasks. In addition to the extremely high cost-effectiveness, users particularly appreciate these advantages:
- emission-free
- low-maintenance
- fast and precise
- robust
application example

Siphon in the sanitary area

Cost-effectiveness and freedom from particles were at the forefront of this application. A cover is joined to the front and back of the natural/black polyamide assembly using quasi-simultaneous welding.

Due to the mixed batch production with other similar assemblies, a complete system is predestined for production. The EVO 2800 is particularly suitable due to its intuitive operating concept, easy process changeover using the EvoLaP process software and integrated process monitoring.
