New M-Series Vibration Welders Deliver Higher Frequency, Higher Power
Branson Ultrasonics Corporation has introduced the new M-Series linear vibration welders. The M Series includes high-power linear vibration welders, employing the company's new two phase digital drive. This drive technology enables higher power to be delivered to the parts to be welded.
The VW-6UH pictured at right is the workhorse of our series of Ultra Hy-Line linear vibration welders, which employ the company's proven electromechanical vibrator and new digital drive controller. The vibrator and controller provide precise control of the weld process. Many new features are available from the Windows NT-based software, including:
An active matrix "human" touch screen (HMI) with an interactive color TFT interface and Pentium-based (Windows NT) software is extremely user-friendly and includes the storage of multiple setups and graphical SPC charting.
A diagnostics program, which allows the machine, with a known tool weight, to be compared to a known set of conditions (run before the machine ships from Branson's facility). This enhances machine troubleshooting capabilities.
15 HP digital vibrator, for precise control of amplitude, from 0.040"to 0.070" in increments of 0.001" This drive supports an 80 lb. top tool weight capacity and a part size of 48" X 20".
Branson has developed a new line of controls for the Ultra Hy-Line Vibration Welders, incorporating the most comprehensive feature package in the industry. Highlights include:
Pentium®-based processor in an industrial grade computer
Color touch screen controls
Windows 95® operating system
Wonderware® software for screen generation
Real time statistical process control (SPC)
Alarm history
Three (3) welding modes
Self-tuning capability
Amplitude and force profiling
Lift table linear displacement transducer
Process verification through alarm limits
Front panel printer available as an option

Branson's Hy-Line series of linear vibration welders employ the company's patented and long proven electromechanical vibrator and a new digital drive controller to provide better control of the weld process along with many other new features not available on current equipment.
The VW-4H, at right, includes: A hydraulic lift and clamp system which includes two proportional valves to control the speed of the lift table and the clamp force applied to the parts. This system allows the operator to input as many as eight (8) weld forces and times to provide an accurate control of the weld meltdown velocity. It is also possible to input up to three (3) hold forces to secure the parts as they cool after welding.
A new controls system using Branson's proprietary control package, EPIC (Enhanced Processing Industrial Computer). This system is a microprocessor STD BUS based, 80x86 single board compatible control package. All system parameters are set through a 24 key tactile feel membrane operator interface with a 4x20 LCD large character readout. The EPIC system monitors the welding parameters and controls all functions of the machine.
SPC capabilities. The microprocessor program will provide a data stream to a communication port to enable the user to hook up a computer and log the weld parameters over a period of time. The data can then be manipulated by the user's program to provide a printout in any number of forms: bar charts, histograms, or range charts.
Branson L-Series linear vibration welders are complete plastics assembly systems designed to weld large or irregularly-shaped thermoplastic parts. The model VW/4L (at right) will handle parts up to 33 inches long by 18 inches wide (838 x 457 mm, or multiple smaller parts.
The VW/4L has a 10 Hp digital power supply with nominal adjustable vibrating frequency of 240 Hz. Modular construction also allows the individual components (vibrator assembly and power supply/control panel)to be adapted to automated or custom systems.
The Mini II vibration welder has the smallest footprint in the industry (2' x 4'), yet offers all of the advantages of the vibration welding process with enhanced performance, ease of operation and added serviceability features.
The Mini II's increased stroke (up to 15" max.) and platen size can handle parts up to 7" (178 mm) long by 9" (230 mm) wide. Additionally, it features a TCP Quick PanelT™ touch screen operator interface that is both accurate and user-friendly.
Branson introduces the Mini II Ergo Vibration Welder. The Mini II Ergo is a full-featured linear vibration welder with load height adjustment - the welding surface can be raised or lowered to accommodate operator height - and the smallest footprint in the industry (3 feet X 4 feet), yet offers all of the advantages of the vibration welding process with enhanced performance, ease of operation and added serviceability features. Significant Features of the Mini II-Ergo vibration welder:
Load height adjustment - the welding surface can be raised or lowered to accommodate operator height.
Ergonomic design features such as banner opti-touch start buttons with an anti-tie-down feature and an emergency stop button are mounted on the frame. The likelihood of accidental and repetitive motion injuries is decreased. · The solid-state, 5.0 hp power supply has an adjustable vibrating frequency (nominal 240 Hz) and is housed in a standard NEMA 12 enclosure. This enclosure is equipped with a fuse-disconnect switch featuring a door-mounted operating handle.
The Mini II can handle parts up to 7" (178 mm) long by 9" (230 mm) wide. It has a 15" machine stroke. a drive fixture weight capacity of 4-5 lbs. (1.8 - 2.3 kg) which provides access to a broader base of applications.
An accurate and user-friendly TCP Quick PanelT touch screen interface.
It is light and compact enough to be mounted on casters and moved next to an injection molding machine or work cell, if desired
Branson produces large part vibration welders in many configurations. Single and double vibrator head machines are produced to customer specifications to meet their unique needs.
Typical applications handled by these welding systems include:
