Forging Forming
 |
| Process | Warm forging and controlled cooling of gears and shafts |
| Equipment | MME 2000, PK2500 forging line |
| Introduction | 900-950℃ warm forging technology used on gears, decarburization 0.05mm on forgings, controlled cooling process to avoid normalization process |
 |
| Process | Monoblock film treatment and cold forging |
| Equipment | Forging line for dog gears |
| Introduction | Monoblock filming technology used, runout of forged dog gears 0.06mm max., cold forging datum consistent with machining datum |
 |
| Process | Cold extrusion of shafts |
| Equipment | MML 1250 extrusion line |
| Introduction | Cold extrusion process used on shafts at multiple work station, runout of extruded shafts 0.50mm max. and machining allowance at one side 0.75mm |
 |
| Process | Isothermal normalizing |
| Equipment | Isothermal normalizing line |
| Introduction | Isothermal normalizing at controlled atmosphere (0.3%wt carbon potential) to improve cold forging performance and avoid CO2 decarburization, as a result to restrict surface oxidation and non-martensite structure |
