Problem Statement · Business Challenges

What needed to be solved

Assessing the optimal supplier for chassis ladder production in Northern Europe and determining the overall cost effect of producing side rails in India.

  • Nominating the European main supplier for the chassis ladder assembly
  • Negotiating the supply price with shortlisted manufacturers
  • Determining the manufacturing location for chassis rails - India vs Europe - based on cost, quality, and delivery

Scope of Work

What Emithran was tasked to do

  • 1.Evaluate the existing design to ascertain the cost of the chassis ladder frame assembly using the should-cost methodology specific to Northern Europe
  • 2.Estimate the manufacturing costs for chassis rails produced in India

Key Aspects

  • 1.Ideal process planning with advanced technology integration
  • 2.Appropriate machine selection
  • 3.Precise process parameter determination
  • 4.Contemporary cost data for materials, machinery, and labour at the manufacturing site
