Selection Method for Appropriate Materials for Designers in Precision Deep Drawing Processing
This time, we will focus on stamping processes and explain a simple method for selecting materials suitable for stamping for designers.
Rational material selection enables the design of products that are easy to manufacture, leading to reduced costs due to fewer processes, improved productivity during mass production, and enhanced reliability and durability of the products. Designs with high forming difficulty will increase material and processing costs. Indicators of material properties for evaluating materials suitable for stamping include tensile strength, yield strength, elongation, hardness, Erichsen value, limiting drawing ratio, and conical cup value. However, two specific characteristic values that can directly evaluate formability are as follows: 1. The n-value representing work hardening characteristics 2. The r-value (Rankford value) representing anisotropy The n-value and r-value are characteristic values that directly relate to the quality of actual stamping processes, and this evaluation allows for the selection of appropriate materials. *For more details, please download the PDF or contact us.*
