Others New Development Parts

We are now putinng great effort into developing, manufacturing and marketing electric double layer capacitors [EDLC] in order to contribute to future motorized society.
In addition, we are developing various cast-in products utilizing the dissimilar material bonding technology, which effectively use know-how of our main product cylinder liner.

Electric Double Layer Capacitor

The EDLC has electric double layer between electrode and electrolyte instead of derivative,So EDLC is free from chemical reaction like battery. EDLC has higher capacitance and longer charge-discharge cycle life.

As-cast Parts

TPR holds the centrifugal casting technology of the cylinder liner for automobiles, especially the manufacture technology of circumference As-cast(Spiny:mushroom shape projection), and we developed new bonding component parts based on this technology.

As-cast Parts

Use the strong adhesion which is the feature of Spiny bonding component, insert the circumference of small diameter pipe parts with aluminum, we can make parts like bearing, center boss, bush, and so on.

As-cast Parts

By carrying out resin insert molding to an aluminum spiny plate, it makes part lighter weight and strengthen.
