Securing fasteners Weld Systems Integrators Inc (WSI) is offering its new 12J series capacitor-discharge welding equipment to join fasteners to hot stamped, high boron steel. The welders are designed to deliver high peak currents (175,000+ amps) in 3 milliseconds, resulting in total weld times of below 10 milliseconds. The company says that very short weld times with high welding forces result in consistent, high quality projection welds. These welds exceed push-out and torque requirements without damaging threads or creating an unacceptable heat affected zone. Less than 60 amps, single-phase, and no water cooling make the single- and multi-head welding machines suitable for producing projection welds to hot stamped and press-hardened, high boron steel.

Lighter shielding PolyOne has rebranded its ElectriPlast material technology as Surround™ EMI/RFI shielding formulations. These conductive thermoplastic materials shield sensitive electronics from both electromagnetic interference (EMI) and radio frequency interference (RFI). Surround’s long-fiber material is suitable for advanceddriver assistance systems (ADAS), replacing metal in shielding applications. As automakers continue to add ADAS functionality, more electronic control units, cameras, and sensors are needed for the systems to function. In addition to minimizing crosstalk between electronic components, Surround is up to 60 percent lighter in weight and is easier to process than traditional materials such as aluminum or copper. Injection molding also permits more complex shapes and fewer design constraints than aluminum or copper, all without compromising on dimensional stability of the component during use. The Surround range is durable and non-corrosive in long term use, and is customizable, including pre-coloring, to application needs.
