Problem Statement

The demand for hot stamped components in the automotive industry has been increasing due to the advantages of the hot stamping process. However, existing experimental setups face challenges such as difficulty in formability determination, achieving uniform temperature, and controlling cooling rates. Larger experimental setups also struggle to achieve higher velocity and specific strain rates

Uniqueness of the Solution
  • Simulates industrial hot stamping processes on a lab scale. 
  • Enables accurate formability determination at various temperatures and environmental conditions. 
  • Allows for cooling using air, water, or argon. 
  • The setup includes a die and punch with specific configurations to facilitate detailed analysis of smaller components.
Prototype Details

A prototype of the apparatus has been developed and tested, demonstrating its capability to simulate industrial hot stamping processes and perform formability tests on various materials under controlled conditions

Current Status of Technology

The technology has been designed, manufactured, and tested using a Gleeble-3800 machine. It has been successfully used to determine the formability of various materials including aluminum, magnesium alloys, and different grades of steel.
