Reshoring Injection Molding After years of offshoring, many companies are bringing manufacturing back.
But reshoring isn’t always the right answer. Here’s how to analyze the decision with real numbers and real risks.
Understanding the Reshoring Trend

The Bottom Line Reshoring decisions should be based on total cost, not just purchase price.
When you factor in quality, inventory, risk, and responsiveness, the math often shifts. Use complete TCO analysis. Consider risk explicitly. And don’t assume offshore is always cheaper or domestic is always better. Make decisions based on facts, not assumptions. That’s how you improve your supply chain.
