Fakuma 2009

This year's anniversary of the FAKUMA trade fair in Friedrichshafen also marked the 20th time BRANSON of Dietzenbach, Germany, attended this key event for the plastics processing industry. The exhibitor of the first hour and worldwide leader in joining technology presented machines, tools, and application solutions across the entire range of serial welding methods for thermoplastics.

This year's anniversary of the FAKUMA trade fair in Friedrichshafen also marked the 20th time BRANSON of Dietzenbach, Germany, attended this key event for the plastics processing industry. The exhibitor of the first hour and worldwide leader in joining technology presented machines, tools, and application solutions across the entire range of serial welding methods for thermoplastics.

Developments in the field of ultrasonic welding technology have focused on the design of systems for flexible integration with custom applications, the communications capabilities of these devices, as well as on continuously transparent data transmission. This development is epitomised by highly compact and modular power supplies like Digital Compact (with digital I/O) and Professional Compact (with a standardised Fieldbus interface for parameterisation and process data transfer).

Recently, BRANSON has also focused on contactless heating of joining surfaces using broadband infrared in order to meet the increasing demands of automotive and medical technology applications with state-of-the-art joining solutions. Traditional welding methods are frequently pushed to their limits by three-dimensional moulded parts, the use of functional fillers and low-viscosity materials, as well as increasing demands to cleanliness and particle-free welds.

Based on the results of joint industrial research, a robust, mid-wavelength, contour-tracking emitter system was developed that makes use of the self-absorption spectra of typical plastics. Since 2004, this system has proven itself in a large number of highly varied serial manufacturing applications. Flexible metal-screen emitters guarantee a contactless and uniform plastification even for welding surfaces with complex geometries, to facilitate either 'pure' infrared welding or a flawlessly clean subsequent vibration weld process. This highly energy-efficient heating method can also be combined with servo-electrical drives for IR units and tool receptacles to provide precise and dynamic process control and additional energy savings potentials – a technology that is already established as the state of the art in injection moulding.

In order to allow for the consideration and conception of application and material-specific solutions in the early development stages of a product, and to minimise the risk of having to implement costly and time-consuming corrections later on, BRANSON also offers comprehensive consulting services for various serial welding technologies (ultrasonic, rotation, vibration, heating element, infrared, laser) through the Plastic Joining Consulting Group. This approach is complemented by segment-specific market cultivation (e.g. in the fields of ultrasonic cutting, packaging, household appliances, and OEM customers) to focus on typical customer requirements in component development and application implementation.
