e-Axle Unit Products

Output Shaft

Process	Cold Forging + Machining
Weight	Up to 3 kg
Features	Cold forging and machining processes, which have been common in the past to separate production lines, will be combined into one, and customer’s machining processes will also be actively incorporated to realize inexpensive, high-value-added manufacturing.

Output Shaft

Counter Driven Gear

Process	Hot Forging + Cold Forging
Weight	Up to 7 kg
Features	A partial cold forging method is applied to hot forgings for higher precision. This method greatly reduces or eliminates the customer's machining process, resulting in significant cost reductions.

Counter Driven Gear

Differential Ring Gear

Process	Hot Rolling Mill
Weight	From 2 kg to 6 kg
Features	The hot rolling mill method, which enlarges ring-shaped hot forgings at high temperatures, is the most suitable method for manufacturing differential ring gears. We provide low-cost, environmentally-friendly products with industry-leading high yields and energy-saving technologies.

Crankshaft

Crankshaft for Small Serial 3-Cylinder Internal Combustion Engine

Process	Hot Forging
Weight	Up to 10 kg
Features	We developed a method of forming two small crankshafts that are connected together and then splitting them in a later process to achieve high productivity and resource conservation. We provide high-quality products at low cost.

Crankshaft for Small Serial 3-Cylinder Internal Combustion Engine

Connecting Rod and Cap

Process	Hot Forging
Weight	Up to 2 kg
Features	We provide high-quality products at a low cost in response to customer requests, using the near-net-shape technology we have developed over many years. We also propose steel products for further functional enhancement.

Connecting Rod and Cap

Transmission Products

By choosing and combining the optimum forging methods according to the product specifications, we can achieve unprecedented high functionality.

Transmission Products

CVT Primary Shaft Parts

Process	Hot Forging + Machining + Cold Forging
Weight	Up to 5.5 kg
Features	Cold forging technology for high-precision inner splines that are difficult to machine was developed to achieve drastic reductions in machining time and cost reductions.

CVT Primary Shaft Parts

CVT Secondary Shaft Parts

Process	Hot Forging + Machining + Cold Forging
Weight	Up to 7 kg
Features	Partial cold forging is applied to hot forged parts with long shafts, eliminating machining of parking lock gears. This greatly reduces or eliminates the customer's finishing machining processes, resulting in significant cost reductions.

CVT Secondary Shaft Parts

Drive Pinion

Process	Warm Forging
Weight	Up to 3 kg
Features	We developed a warm forging technology that can be used to forge parts at lower temperatures than hot forging. Warm forging enables near-net-shaping of the entire product as well as deep holes, greatly reducing the customer's finish machining processes. We also contribute to the reduction of CO₂ emissions due to lower temperature forging.

Drive Pinion

Counter Driven and Drive Gear Parts

Process	Hot Forging + Cold Forging + Machining
Weight	Up to 7 kg
Features	Partial cold forging is applied to hot forged parts, eliminating machining of parking lock gears. This greatly reduces or eliminates the customer's finishing machining process, resulting in significant cost reductions.

Counter Driven and Drive Gear Parts

Differential Ring Gear Parts

Process	Hot Rolling Mill + Machining
Weight	From 2 kg to 6 kg
Features	The hot rolling mill method, which enlarges ring-shaped hot forgings at high temperatures, is the most suitable method for manufacturing differential ring gears. We provide low-cost, environmentally-friendly products with industry-leading high yields and energy-saving technologies.

Differential Ring Gear Parts

Planetary Ring Gear and Other Ring-Shaped Parts

Process	Hot Forging + Cold Rolling Mill, Hot Rolling Mill
Weight	From 1 kg to 4 kg
Features	In addition to the hot rolling mill method, we also use the cold rolling mill method, which enlarges ring-shaped hot forgings at room temperature, and we propose this technique based on the parts specifications. We provide low-cost, environmentally friendly products with industry-leading high yields and energy-saving technologies.

Process	Hot Rolling Mill
Weight	From 2 kg to 7 kg
Features	The hot rolling mill method, which enlarges ring-shaped hot forgings at high temperatures, is the most suitable method for manufacturing differential ring gears. We provide low-cost, environmentally-friendly products with industry-leading high yields and energy-saving technologies.

Differential Ring Gear

Drive Pinion

Process	Warm Forging, Hot Forging
Weight	From 1.8 kg to 5 kg
Features	We developed a warm forging technology that can forge parts at lower temperatures than hot forging. Warm forging enables production of near-net-shapes of entire products as well as multistage axles and greatly reduces the customer's finish machining processing. We also contribute to the reduction of CO₂ emissions due to lower temperature forging.

Drive Pinion

Axle Shaft Parts

Process	Hot Forging + Cold Forging
Weight	From 4 kg to 12 kg
Features	The flange part (round shaped or cross shaped) at the end of the shaft is hot forged, and the shaft part is cold forged (extrusion method) after hot forging to achieve high yields. Since the dimensions of the shaft after cold forging are highly precise, the customer can perform machining-less finishing.
