A team of Molex engineers is working to accurately predict how their connectors will work, down to the individual component level, by using fully functional digital replicas to virtually validate their designs. The innovative use of digital twins will help lower costs, reduce recall risk and speed up the time it takes for a product to make it to market.

Engineers at Molex, a Koch company, are taking the idea of digital twins — fully functional virtual replicas of physical products — to the next level.

The engineers have created models that can accurately predict and virtually validate how parts will work down to the component level — enabling customers to have a much better understanding of how their connectors will function throughout their lifespan before even being put into production. This helps lower costs, reduce recall risk and cut down on the amount of time used on physical testing and revisions.

The implementation and innovation around digital twins at Molex have also led the automotive division to transform the way it operates so it can better utilize the technology's capabilities and meet the fast-changing needs of leading-edge car manufacturers.

In the past, the engineers who would simulate what would happen with a given design and the engineers testing the designs operated in mostly separate worlds, with one group working away on equations and the other developing and testing physical products. The team at Molex recognized there was an opportunity to combine their efforts using digital twins, forming one predictive engineering team.

“We took the power of simulation and the power of experimentation and combined them,” says Vijy Koshy, a Molex senior director of engineering. “It’s a small group of people we deployed and told your job is to predict the future through physics.”

So far, the team has been able to create a high-fidelity digital twin that can accurately predict and validate a connector's current rating with 95% accuracy. The model helps eliminate the need for months of physical testing.

And when they do perform physical tests, they’re testing to validate the data predicted by the digital twin, not to see if it meets some specification. With the knowledge the digital twins provide about current rating and other mechanical functions, they’ll create connectors that meet or exceed any other required specifications and work with their customers to come up with solutions to solve the specific challenges they’re facing.

The lessons learned from these early electrical models will also soon be applied to other areas of the connector, such as its mechanical, sealing and thermal functioning. In addition to using these advanced digital twins to develop predictive models for its connectors, Molex is also using them to model and optimize production lines and develop 5G antenna systems for modern cars and trucks.

The knowledge gained is shared with engineers across Molex to improve connector design and reliability wherever they are in the world. Mutual benefit at its best.

Creating value. Transforming life.

Our life’s work is to help people improve their lives by making and innovating products and services our customers value. Our focus is on delivering mutual benefit: Win-win outcomes that make life better for customers and employees alike.

Based in Wichita, Kansas, Koch Industries is one of the largest private companies in America. A diverse set of businesses and industries across the world, we work together to keep improving and exploring new ways to make life even better.

Koch companies are involved in manufacturing, agriculture, pulp and paper, packaging, consumer products, building materials, glass, automotive components, refining, renewable energy, chemicals and polymers, electronics, enterprise software, data analytics, medical products, engineered technology, project services, recycling, supply chain and logistics, global commodities trading, and investments. Since 2003, Koch companies have invested more than $150 billion in growth and improvements. With a presence in about 60 countries, Koch companies employ more than 120,000 people worldwide, with about half of those in the United States.

Stewardship in all we do.

Our approach to Environmental, Social and Corporate Governance (ESG) is different than most. We believe in people and seek a system of equal rights and mutual benefit where individuals succeed by helping others succeed – and where people are empowered to improve their lives and their communities. It’s why we focus on empowering individuals to improve their lives and communities through bottom-up solutions rather than top-down imperatives.

Environmental Stewardship

Consuming fewer resources, minimizing waste and constantly innovating to improve our manufacturing processes and performance is essential to the way we do business – benefiting our customers, employees, investors, communities and planet.

Five environmental stewardship priorities.

With more than 300 manufacturing sites across the United States – and about 100 more globally – we’re one of America’s largest manufacturers. Every day, across those sites, we strive to create more value, using fewer resources than the day before. We do it through constant improvement and innovation – both in the products we make and how we make them, and by managing our resources in a way that benefits our customers, employees, partners, community members and society.

  • Innovation
  • Energy Efficiency
  • Air Quality
  • Water
  • Responsible Resource Management

Social Stewardship

Philanthropy. Health and safety. Diversity and inclusion. Meaningful, rewarding careers and community outreach. These are just some of the vital priorities of social stewardship that empower each of our employees to develop, contribute, self-actualize and create value for the world while supporting communities in which we live.


Our management framework, Principle Based Management™, is based on proven principles of human progress and a deep appreciation for the dignity of every individual. Our private ownership, shared Vision, Values, compliance standards and oversight all help us focus on long-term value creation.
