Powertrain Unit Factory manufactures components vital to Honda's high performance, high quality automobiles, supplying Honda's factories domestically and globally. Its automated production line and strict quality control enables integrated production from materials to finished products.
Powertrain Unit Factory has evolved, flexibly accommodating changing times.
Engine Valve Plant is established in Moka city, in accordance with Honda's first satellite plant concept. Began with a staff of 35, consisting of five associates from Wako Plant and locally-hired staff.
Component Plant and Valve Plant are established within the same industrial complex.
Production of Honda's uniquely developed Constant velocity universal joints began.
Components Plant absorbs Valve Plant as the Moka Plant.
Buggy engine production commences.
World's first fully-automated crank forging line.
Aluminum wheel production commences in Japan and the US simultaneously.

Haga Plant, First Site absorbed by Moka Plant.
Takanezawa Plant transferred to Suzuka Factory.
The 4,500t press line completed in March, 2005 is a world-class forging line culminating all of Honda's hot forging technologies.
Single pressing machine capable of forging various components such as crankshafts, transmission gears and hypoid gears, at industry-leading cycle times.
Setup for a 5,000t press that took 3 associates 40 minutes, was reduced to one associate taking 10 minutes for a 4,500t press, drastically improving productivity.
By succeeding in the replacing of graphite as a parting agent for crankshaft forging with a reusable "white" parting agent, liquid waste was reduced to zero, realizing a clean facility.
Oxide scale scatter typical of hot forging is managed by a "Scale recovery device," a "tub" surrounding the press, collecting and channeling scale to a basement pit, which is then taken outside of the building by conveyor belt.
* Parting Agent: Liquid used in forging press to separate product from mold, acting as a lubricant and coolant.
* Oxide Scale: Thin membrane appearing on material surface when heated.
