Picking the right materials and designing for manufacturing work together to make better products more efficiently

 Understanding material properties is paramount in engineering as it lays the foundation for effective material selection, manufacturing process selection, and design for manufacturing
Material properties such as strength, durability, and thermal conductivity influence how a material behaves under various conditions, directly impacting product performance

Choosing the appropriate manufacturing processes based on material properties and design requirements is essential for efficient production. Design for manufacturing further complements this process by optimizing product designs to streamline manufacturing workflows, reduce costs, and minimize waste. Together, this holistic approach ensures that products are not only well-designed but also manufacturable with ease and efficiency.

Key steps in design process include

  • Understanding Material properties and selecting apt material
  • Selecting apt manufacturing process
  • Designing with manufacturing process in mind
