RAPA Automotive Celebrates the 10 Millionth HIS®

RAPA Automotive Celebrates the 10 Millionth HIS®

The 10 millionth HIS® (hydraulic impulse storage system) recently rolled off production line 1 at the Selb plant – precisely on 05.07.21 at 10:51:21. If that’s not a reason to celebrate.

“We are very proud of this production success,” says Production Manager Hartmut Popp. With a team of around 80, production hall 3 currently produces around 8,500 parts every day. On the second production line, around 8.3 million parts come off the assembly line, bringing total production to around 18 million since the start of production in 2009. Deliveries are made to the fifth largest automotive supplier.

RAPA congratulates the team on the production success and reaching the mark of ten million products.

The HIS hydraulic impulse oil storage system is an additional component for 8-speed automatic transmissions that enables a start-stop function. . It is a springloaded piston accumulator that fills with oil during driving and tensions a spring. This reserve, which is about 100 centiliters in size, is fed back into the hydraulic system by the spring at lightning speed when the engine is started, creating sufficient oil pressure to actuate the shift elements of the automatic transmission required for startup. With HIS®, an additional pump (electric hydraulic pump) or more powerful oil pump on automatic transmissions are no longer needed, because it ensures start-stop capability and requires very little electrical power. It is easy to install and requires no major modifications to the transmission. The start-stop function reduces fuel consumption by a further 5 percent.

The HIS® is not only manufactured at our site in Germany, but also at our plant in the USA. Here, series production began in 2015. RAPA continuously invests in the Auburn production site and since the start of production, the manufacturing capacities of the US plant have been steadily increased. Today, US production stands at 3.5 million HIS® components.
