The new line has a combined press stamping capacity of 7,900 tonnes, making it the fastest and one of the biggest and most powerful press lines across JLR, stamping both steel and aluminium panels, the company said in a statement.
Commenting on the development, Jaguar Land Rover, Operations Director-Halewood, said the new press line reinforces Jaguar Land Rover's long term investment in UK manufacturing.
"This investment ensures we can make more panels, even more efficiently and will continue to do so for many years to come," he added.
The new press line will speed up the delivery of the required volume of pressed parts produced at Halewood.
The company said installation of the metal stamping press will be completed by the end of March and trial pressings will commence in April and the facility will begin stamping panels for use across Jaguar Land Rover from the Summer.
"By Autumn the facility will be up to full speed making up to 20 strikes per minute," it said.
The line will help to feed the body shops across Jaguar Land Rover which are working around the clock to meet increasing global demand its vehicles.
