Automated connection of medical components for maximum output
Perfect for automated assembly: Thanks to minimized welding times and real-time process control, ultrasonics is ideal for manufacturing medical components in high volumes. Find out the advantages of the technology for your application in this article.
Joining Plastics of Medical Devices Without Adhesive
Particularly for medical products with direct skin contact, high wear comfort and skin compatibility are crucial for the quality of the product and customer satisfaction. Manufacturers should therefore avoid chemicals such as IBOA and connect plastics with processes that do not require adhesives, solvents or environmentally harmful substances - ultrasonics make this possible.
The switch from PVC to thermoplastic elastomers (TPE) in medical technology promotes health and environmental protection. TPE is phthalate-free, biocompatible and easier to recycle, which reduces the risks of allergies and environmental pollution. Despite challenges in joining TPE, ultrasonic welding offers an effective solution for stable and durable joints. This step improves product quality and minimizes health risks in the medical industry.
Minimal scrap rates with twice as fast cycle times: New developments in ultrasonic welding enable an optimization of production and can permanently reduce manufacturing costs for batteries and wire harnesses. A big help comes from the experience gained in the welding of plastics.
Increasing the sustainability of EV with ultrasonics
Sustainability becomes particularly interesting for companies when combined with cost savings. However, is that possible in the production of electric vehicles? As a particularly efficient, safe, and material-friendly process, ultrasonic welding offers some exciting options.
Utilizing the digital potential of battery manufacturing
Up to 150 data points per welding process: Ultrasonic welding offers exciting opportunities for the digitalization of battery production - both in manual workstations and automated systems. If the data is used correctly, both safety and efficiency can be permanently increased, and new standards can be set in quality control.
Unlocking the potential of Digitalization with ultrasonic welding
The most valuable resources in manufacturing are no longer materials or machines. It is the data. Whether in automated systems or at manual workstations: Every welding process of battery cells or wire terminal applications offers the opportunity to collect valuable digital information.
Joining medical applications quickly and sustainably with ultrasonics
Connecting plastics without adhesives: Using ultrasonics as a joining technology, companies can produce their applications skin-friendly and eco-friendly. If certain specifications for the components are met, the process can also be used for sensitive applications with complex geometries.
