Materials Development Technology

One of the fundamental supports of NHK Spring Group's manufacturing is materials development geared to evolving the actual materials that are used in products.

Steel materials for springs developed jointly with materials manufacturers

POINT1

Joint Development of Spring Materials

As the world's foremost general spring manufacturer, NHK Spring jointly develops high-strength and high-toughness steel materials for springs with material manufacturers according to the required characteristics of the market.

Our metal substrate (right) has excellent heat dissipation performance thanks to the insulation layer we have developed in-house.

POINT2

Insulation Layer Development for Integrated Metal Substrates (IMS)

Our metal substrates, which are available in copper, aluminum, iron, etc., are valued for their "heat dissipation performance". The key to this heat dissipation performance is the "insulating materials" that we develop in-house. In recent years, metal substrates have been attracting increasing demand and attention due to automobile electrification and other factors.
