The lab develops metal forming methods for making lightweight, high-strength parts.
AboutAbout the lab
Making light, strong parts through plastic working
The Plastic Working Lab researches and develops metal forming methods that achieve higher strength, lighter weight, higher functionality, and low environmental impact.
The lab works on metal forming that uses the vibration motion of servo presses, and on developing forming methods for lightweight parts.
On the lab's website, it is also introduced under the name "Maeno Lab."
Key terms
- Metal forming
- Processing that applies force to metal to change its shape without cracking it. Examples include pressing and forging
- Servo press
- A press whose pressing motion can be controlled in fine detail
- Hot stamping
- A method of forming a metal sheet by pressing it while it is heated
ResearchResearch themes
This lab researches and develops plastic working methods that achieve higher strength, lighter weight, higher functionality, and low environmental impact. Its research is divided into metal forming that uses the vibration motion of servo presses and the development of forming methods for lightweight parts.
*Illustrative imageMetal forming using vibration motion
The lab studies processing that uses the vibration motion of a servo press. In sheet forging, automatic re-lubrication by load vibration lowers the forming load, and in vibration forging, the lab is developing bonderless forging. In punching holes in thick stainless steel plates, it works on improving the quality of the sheared surface.
*Illustrative imageDeveloping forming methods for lightweight parts
As methods for forming lightweight parts, the lab is developing sheet-forging hot stamping and thickness-increasing tailored hot stamping. It is also working on developing high-productivity hot stamping of heat-treatable aluminum alloys.
