In order to establish a better understanding of the use of Powder Metallurgy components in a modern plug-in hybrid vehicle, a team of engineers from Höganäs China is undergoing a project to tear down a BYD Tang DM hybrid SUV. Currently, the team in Shanghai is dismantling the car to identify the components that are either made from Powder Metallurgy, or which could be converted to Powder Metallurgy.

The BYD Tang is a plug-in hybrid crossover sport utility vehicle developed by Chinese automaker BYD. Its 18.4 kWh lithium iron phosphate battery pack is said to deliver an all-electric range of 80 km (50 miles) from two electric motors, front and rear. The Tang has a 2.0 litre internal combustion engine and is fitted with a Dual Mode (DM) system, allowing drivers to switch between all-electric mode (EV mode) and hybrid electric mode (HEV mode).

The teardown follows on from a similar project in 2017, where a team of engineers from Höganäs stripped back three new vehicles to their component parts. The full report can be read in the Summer 2017 issue of Powder Metallurgy Review magazine.

Powder Metallurgy:The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
