Branson 107 Orbital Welder
Orbital vibration welding is a frictional process that uses an electromagnetic drive to create relative motion between two thermoplastic parts. This constant velocity motion generates heat, which raises the material temperature at the joint to its melting point. The motion is stopped after sufficient material is melted. The plastic then solidifies and forms a permanent bond.
Branson 107 orbital vibration welder, used to seal plastic cases and junctions for automotive and other industries. Orbital welding is optimal for plastic joining especially with tall unsupported sides.
The DVW2 Series utilizes a proven hydraulic lift and clamp system already found on Branson’s Hy-Line Series. The standard version comes with a Siemens S7 PLC with TCP Quickpanel Jr. monochrome operator interface. Weld control is available in time mode or an optional meltdown (collapse) mode.
New Features
• 11 kW digital power supply with adjustable frequency (180-240 Hz).
• Front operator door allows free access to working area of machine for tooling and maintenance.
• Accessible machine leveling feet.
• Hydraulic power unit at side of machine for easier access to working area for automation and maintenance.
• New sound enclosure design provides greater noise attenuation.
Other Features :
• Constant velocity orbital motion (orbital units) results in more welding power in short weld times.
• With the orbital model, omnidirectional motion enables welding of taller, unsupported vertical walls. No wall is ever perpendicular to welding motion since motion is in all directions.
• Lower weld amplitudes (less than 0.030 inch for some applications) reduce part clearance requirements. Flash is displaced less, and its character is more homogeneous.
• Adjustable frequency allows tool design flexibility.
• Programmable control - precise machine control is easily modified to integrate robotics, pick & place, and tooling requirements.
• Closed loop amplitude control.
• Front accessible touch pad interface.
• Internal lighting.
Typical Sequence of Operation
- The parts to be welded are loaded into the lower tooling fixture with the top part placed in the approximate final assembly location.
- Cycle is initiated by activation of two anti-tiedown start buttons.
- When the closed position is reached, the top part is positioned in the upper tooling fixture.
- The welding head is driven at the desired amplitude and frequency while the parts are clamped together under a controlled clamp force.
- After the contact surfaces have melted, the vibration stops, and the parts are centered. The material is allowed to solidify as the plastic parts are held under clamp load.
- At the end of the hold period, the table returns to its home position and the welded assemblies are removed.
