Development of a High-Performance Building Material Using Wood-based Corrugated Panels Manufactured via Cold-Forming Technique

BioResources, 2023
A wood-based sandwich panel with a corrugated core was developed as a building material. A matched-die mold manufactured from commercial plywood was used to fabricate the corrugated panels through a cold-forming process.

Correlating Ultrasonic Velocity in DC04 with Microstructure for Quantification of Ductile Damage

Journal of Manufacturing and Materials Processing, 2023
The detection of ductile damage by image-based methods is time-consuming and typically probes only small areas. It is therefore of great interest for various cold forming processes, such as sheet-bulk metal forming, to develop new methods that can be ...

Wood-based Corrugated Core Sandwich Panels Manufactured Using a Wooden Mold

BioResources, 2023
A wooden matched-die mold was manufactured to develop wood-based corrugated panels. Wood veneers brushed with resin were cold pressed between the mold halves and formed into a corrugated geometry.

Determination of the Optimal Reduction Ratio for Least Springback during Cold Drawing of Seamless Tubes [PDF]

Journal of Applied and Computational Mechanics, 2018
Cold drawing process is one of the most used metals forming processes in industries for forming seamless tubes. This process of plastic deformation of metals occurs below the recrystallization temperature and is generally performed at room temperature ...

Numerical investigation of manufacturing hollow preforms by combining the processes backward cup extrusion and piercing

MATEC Web of Conferences, 2016
Hollow or tubular preforms are used to meet lightweight requirements and reduce production costs of cold formed components. In order to increase efficiency of manufacturing, a combined forming process was developed, which will be presented in this paper:

Mechanical properties and formability of EN AW-7075 in cold forming processes

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Due to a low density and high tensile strength, the aluminum alloy EN AW 7075 T6 offers a high lightweight potential for structural components. Since its formability is limited at room temperature in the T6 temper state, the potential of this alloy for automotive bodies is only utilizable by adapted deep drawing processes.

Investigation of tribological properties of AlMg4,5Mn0,7 in a warm forming process using the barrel compression test

, 2022
S.633-638Within the German Collaborative Research Center 39 PT-PIESA the forming of micro cavities into aluminum sheets is one challenging task. During this forming process high forces and stresses occur which lead to a high tool wear.

Investigation of the suitability of surface treatments for dry cold extrusion by process-oriented tribological testing

, 2022
S.473-479In cold extrusion of aluminum alloys adhesive wear can be prevented by an excessive lubrication of the process. While this causes additional process steps also environmental risks have to be addressed. Hence, dry metal forming, i.e.
