SiboDur iron alloy-The Company has a license and partnership agreement with Georg Fischer Automotive AG in which Georg Fischer grants the Company a license to use its SiboDur alloy in Japan and South-East Asia. The use of SiboDur allows a much lighter construction of chassis parts in iron and competes successfully with aluminum and steel forgings in terms of performance and weight at a lower cost.
SHORIK quench-solidified aluminum powder alloy-The aluminum alloy contains 20% silicon. The UTS of the SHORIK alloys exceed 450MPa and can be maintained even at 150℃.
Cast iron parts (brake disc rotor)-The Company produces the brake disc rotor only in Indonesia for supply to Japanese OEMs. -The Company supplies the crankshaft for Mitsubishi Motors' 1.8-liter engines.
Cast iron parts (brake drum)-The Company produces the brake disc only in Indonesia for supply to Japanese OEMs.
Piston ring-DLC (Diamond Like Carbon) coating is used to reduce friction on engine components. Installed vehicles: Nissan "Note" (low friction piston ring for spark ignition engine), Mazda SKYACTIV engines (new oil ring (RNS-M、GN-T))、Toyota "Aqua" (new oil ring (RNS-M、GN-T))
Other engine parts (lifter)-DLC (Diamond Like Carbon) coating is used to reduce friction on engine components.

SiboDur - Iron alloy-Acquired a license of SiboDur and signed partnership agreement with Swiss-based Georg Fischer (GF). The Company will manufacture on behalf of GF in Japan and South-East Asia, and GF on behalf of Riken in Europe. -Optimally designed products made from SiboDur, a high-strength ductile alloy, offers reduction in product thickness and weight
Seal ring-The Company estimates its domestic market share of seal rings is approximately 90 percent
Piston ring-The Company estimates its domestic market share of piston rings is estimated to approximately 50 percent

<Preventing Aluminum Adhesion Technology>
- Thermal resistance and wear resistance were improved thanks to the review of solid lubrication and improvement of binder made from thermal resistance resin.
<Surface Treatment Technology>
-DLC (Diamond-Like Carbon) / Amorphous Carbon
|application||material for cylinder||Features|
|periphery||cast iron||less friction + better fuel consumption|
|aluminum||preventing aluminum adhesion and scuffing + wear resistance + less friction|
|lateral||-||measure to abrasion of groove in the piston (preventing aluminum adhesion)|
Deformed Hollow Tilt Camshafts
- Making shaft hole at the core along cam profile achieved weight reduction and less machining cost. Possible to make a hole of the oil-through-bore at one time.
- A combination of bonding techniques and downsizing allowed to reduce weight and to minimize engine size. A barrel shaped type reduced sound at the time of engine revolution and achieved to enhance the quietness. At the same time, less friction was achieved.
Aluminum Alloy Retainer
- Resistant to abrasion and achievement of weight reduction
Processed material parts
Double Wishbone Type Steering Knuckles
- Cost reduction by near-net-shape treatment of complex dimension. Reduced the
back-end process as well as realizing the easier-cutting. The unified component reduced
Strut Type Knuckles
- The unified casting part of complex dimension.
Lower Control Arm
-Deletion of forged product and stamped product
