Molding Weight reduction of structural parts such as used in vehicle

Technical Classification:
[ Molding ]
[ Products / Processed Products ]
[ 500% increase of the structural strength ] [ 80% reduction of weight ] [ as compared to steel components ] [ Improvement of fuel economy by weight reduction ]

Point of the Proposed Technology

Current knowledge is based on the older technology before improving adhesion of the carbon fiber reinforced polymer sheet and its development is temporally put on hold because the structural strength targeted was not achieved, but a mold for insert molding of the carbon fiber reinforced polymer sheet is available.


Weight reduction by 80% as compared to steel products
Structural strength targeted was not achieved when using the sheet before improvement of the adhesion of the insert sheet

Conventional Technology

Design and manufacture of the metal progressive die
Metal stamping and forming
Design and manufacture of the direct-pressure type and injection molding die for resins
Molding of resins
Insert molding
 Metal insert
 Joining insert to the metal part⇒injection to the consecutive metal part
Design and manufacture of automated processing equipment
Ultrasonic welding, fusion, welding, joining by crimping, laser processing, assembly
* Manufacture of molded parts for the automotive electrical and electronic system
* Manufacture of molded parts for medical devices
* Manufacture and sale of medical assistive devices

New Technology

A resin molded part is sandwiched between carbon fiber reinforced polymer sheets as an insert and then compressed to form a structural part with high strength without use of metal.

Technology Deployment and Cooperation

Development Stage
Prototyping / experimental Stage (to be completed in 0/0; progress: 30%)
Intellectual Property Right
Joint Researchers (their role)
Mie University for evaluation of properties
Example of Application
Weight reduction by using only resin as the structural material. Higher flexibility in design
*Insert molding technology in which thick wall parts can be sandwiched between carbon fiber reinforced polymer sheets.
Technical Problems
Use of only resin in automotive structural parts. Shortening of the residence time in molding using high damping effects with the robotic arm.
Collaborator needed to Improve
We would like to cooperate with the carbon fiber manufactures for improving the adhesion to the polymer.
