Branson 3G Laser Welder Demonstrates Clean, Clear, Precise Hermetic Seal Welds
Danbury, Connecticut ( May, 2016)
DANBURY, CONNECTICUT (MAY, 2016) – Branson Ultrasonics, a business of Emerson, will be showing the 3G Laser Welder demonstrating Branson’s Simultaneous Through-Transmission Infrared® (STTIr®) laser welding technological at Med Tech World MD&M East Show, June 14th – 16th, Javits Center, Booth #1939. STTlr laser weld technology is capable of meeting medical device manufacturers’ challenges for a clear-on-clear, particular free, precise weld joint, with superior aesthetic quality, confirming Branson’s position as a global technology leader.
Branson’s Simultaneous Through-Transmission Infrared® (STTIr®) laser welding offers manufacturers the capability to achieve a clean, clear-on-clear, particulate-free, hermetically sealed weld. Branson and Sono-Tek have collaborated in developing an advanced technique for precision application of laser absorbers, employing Sono-Tek’s ultrasonic fine line coating system. The technique applies thin film deposition of a 0.5mm wide line of laser absorber to the weld area, for joining clear-on-clear plastics. STTlr technology is capable of meeting highly specialized manufacturing demands of small geometrically complex devices and does not use vibration force, making it ideal to accommodate delicate parts or those embedded with electronics.
Predecessor laser welding techniques such as scan or trace welding require a laser beam to travel along the weld line of a plastic part, heating and cooling as it goes. STTIr on the other hand, shapes multiple stationary laser beams in a wave guide along the entire length of the weld line. Discrete beam-zone intensity control via a tool map protects delicate structures while assuring uniform weld performance. All the lasers fired simultaneously under a clamp force, heating/melting/and bonding the component parts along the entire weld surface all at once, in a fraction of the time required for trace welding. The wave guide that houses the laser ferrules can be configured on multiple axes to accommodate highly complex 3-D contours, allowing designers to create parts for maximum functionality and ergonomic appeal.
Branson’s 3G Laser Welding System consists of a control and laser banks. It is a compact bench-top controller. It is designed to interface with a single 2000X actuator and up to two Radiance laser banks capable of delivering up to 250 Watts of laser power. This unit is designed to be operated with an external chiller. It offers:
- Unmatched performance and flexibility in a completely modular system approach.
- Laser bank features a new closed loop control system.
- Flexibility and ease of integration is a key principal in the design of the Radiance 3G/3I laser bank.
- SmartFiber optic bundle provides high-efficiency power delivery.
This unit includes DC laser power supplies, CANopen laser bank bus network, 6" LCD touch screen interface, and the ability to control a Branson 2000X Series actuator. The advanced controls include:
- Time and distance welding modes (both collapse and absolute)
- Force measurement
- Process limits with alarms
- Multiple preset memory
- Graphing and weld history data
- Multiple languages
The 3l Welder System is also available offering up to four Radiance laser banks capable of delivering up to 500 Watts of laser power.
