DuPont Mobility & Materials has announced that it will introduce the new Crastin PBT High Laser Transmission Solutions That Enable Automotive Component Manufacturers to Accelerate Production and Improve Performance of Connectors, Sensors, ADAS and Other Sensitive Electrical Components at K Show, October 19-26 , in Dusseldorf, Germany.
“Now commercially available, DuPont offers a full line of new Crastin PBT laser welding solutions. These meet the industry’s need for materials optimized for fast laser welding, while offering significantly improved levels of hydrolysis resistance and dimensional stability,” said Kelvin Tseng, automotive business manager, DuPont Mobility & Materials.
DuPont says laser welding is widely used as the assembly technology of choice for sensitive and miniature applications in the automotive and electronics industries. Since this process does not heat or vibrate the components, it helps prevent damage to internal precision components. Laser welding does not damage the surface of a part and ensures a durable connection. Additionally, laser welding equipment has evolved to allow for very short cycle times.
Three new Crastin solutions have been developed to provide manufacturers with a flexible choice between level of laser transmission, low warpage, and resistance to hydrolysis and chemicals, adds DuPont. For example, one of the new grades offers up to 200% improvement in laser transmission over the industry benchmark, resulting in exceptionally good bonding at fast cycle times. Another offers improved hydrolysis resistance even though it also supports exceptional laser transmission. The third new solution offers superior low warpage performance combined with excellent laser transmission, making it an ideal choice for sensors and electronics enclosures that require high standards of dimensional stability. It also provides the necessary performance in terms of resistance to hydrolysis, the company adds.
“Until now, conventional laser welding solutions have had low levels of hydrolysis resistance,” adds Miles Wang, application development manager, DuPont Mobility & Materials. “Our new solutions improve laser transmission as well as other properties such as resistance to hydrolysis. For our customers, this will create value in both manufacturing and product performance.
