In the heart of the Upper Midwest lies a powerhouse of precision and reliability—Harbor Plastics, a woman-owned leader in custom plastic injection molding based in Minnesota, just 15 miles west of Minneapolis. It’s not just what Harbor Plastics does—it’s where they do it that sets them apart. Minnesota has emerged as a national hotspot for injection molding, and Harbor Plastics leverages the region’s strengths to offer customers unmatched advantages in quality, speed, and cost-effectiveness.

1. Minnesota: A Strategic Hub for Injection Molding

Minnesota’s rise as a key injection molding hub stems from several factors:

• Robust manufacturing ecosystem: With roots in precision manufacturing, Minnesota supports a thriving landscape of plastics, medical device, automotive, electronics, and consumer goods production.
• Skilled workforce & innovation: The state boasts a highly educated, experienced labor pool connected to advanced research and technical education infrastructure.
• Efficient supply chain & distribution: Companies benefit from a strong network of mold makers, material suppliers, and proximity to major logistics corridors facilitating fast and economical shipping across the U.S. Plastic Industry.

This powerful manufacturing foundation amplifies Harbor Plastics’ operations, giving us access to superior talent, materials, and infrastructure.

2. In-House Expertise: From Concept to Completion

Harbor Plastics embodies full-service precision:

• Custom mold building: Our highly skilled engineering team works closely with clients to design, craft, and optimize molds tailored to exact specifications, with durability and efficiency in mind.
• Comprehensive process control: Our company manages the entire workflow—from CAD/CAM-driven design, mold build, injection, to secondary operations—all under one roof.
• Lean operations: Harbor Plastics adopts lean manufacturing practices fueled by continuous improvement—guided by team members like a Six Sigma Green Belt—to minimize waste, reduce costs, and boost productivity.

This integrated approach ensures tight quality control, faster turnaround, and responsive collaboration from start to finish.

3. Cutting-Edge Injection Molding Capability

Harbor Plastics’ production floor is purpose-built for precision and flexibility:

• Equipment range: Our machinery accommodates shot sizes up to 51 ounces and clamping forces between 60 to 350 tons, allowing us to mold both intricate small parts and larger, more robust components.
• Volume flexibility: Whether you need a short-run prototype or a high-volume production run, Harbor Plastics delivers. We can execute projects in as little as two days and offer rush services when timelines are tight.
• Lean, efficient production: Lights-out manufacturing and streamlined processes underscore our dedication to speed and cost-effectiveness.

4. Diverse Solution Portfolio Across Industries
