Automotive Underhood Solutions

We offer a range of welding technologies to help automobile manufacturers around the world build lighter, more fuel-efficient cars. 

A Proven Partner in Reducing Vehicle Weight and Emissions

Our complete spectrum of welding technologies for underhood components helps automobile manufacturers cut costs and meet tougher fuel standards. From manifolds to carbon canisters, we work with manufacturers to identify the optimal welding process. Whether leveraging new advances in laser, vibration and ultrasonic technologies or applying time-tested techniques such as hot plate, infrared, thermal and spin welding, we’ll work with you in our application labs around the globe to design and implement the right solution.

Automotive Underhood Applications

Air Intake Manifolds

Decreasing vehicle weight is a critical automotive manufacturing goal. Branson welding technology helps achieve that and sustain higher-volume production. Vibration welding allows the manifold to be made by joining two halves, rather than molding a single piece. This reduces cost and cycle time.

Manifolds produced this way have been able to withstand the burst pressures that engine combustion generates and have become the industry standard.   


Rack-and-Pinion Boots

Branson’s hot-plate welding technology creates a strong structural weld and hermetic seal, making it ideal for joining rack-and-pinion boots. A cost-effective production method, this technology allows complex geometries with irregular or curved walls to be joined. Eliminating consumables and overcoming part warping with corrective melting, hot plate welding technology allows assembly of parts produced by two different molding processes.   


Turbocharging Housings

By packing more into existing cylinders, turbocharger technology allows automotive manufacturers to get the same powerful performance from a smaller displacement engine while reducing emissions. Branson’s plastic welding technologies are used to create exhaust housings for turbochargers that can withstand a harsher operating environment of higher temperatures and increased pressure. This technology enables manufacturers to meet their goals of reducing vehicle weight and lowering costs. 

Carbon Canisters

Branson’s plastic joining technology plays an active role in helping automotive manufacturers reduce harmful emissions. Plastic welding situates carbon canisters in the vehicle powertrain, where they capture chemical emissions from fuel systems before they can escape into the environment. This technology is customized for individual customer needs so that it meets specific engine demands, fuel tank sizes and regulatory requirements.

Electronic Control Units

Laser technology from Branson safely joins together the plastic parts that contain sensitive or delicate components and might be damaged by vibration, heat or other welding methods. The low force of laser welding contains no vibration and is inherently safer for these parts. Branson’s welding technologies are used to create protective housings for the electronic control unit (ECU) as it conducts operations vital to the operations of a vehicle, including regulating the fuel injection system, ignition timing and idle speed control system.
