Urban Honolulu, HI
No verified plastic injection molding companies found.
Hawaii has extremely limited plastic injection molding infrastructure due to its geographic isolation and the economics of shipping raw materials and finished goods across the Pacific Ocean. The only significant plastics manufacturer in Hawaii is Pacific Allied Products in Kapolei, which specializes in PET bottle manufacturing and expanded polystyrene foam products for the construction industry rather than custom injection molding services.
Businesses in Hawaii requiring custom plastic injection molding services typically work with mainland U.S. suppliers in California, Oregon, or other West Coast states who can ship finished products to the islands.
Notes
Research across these three cities revealed significant regional variation in plastic injection molding infrastructure. Cleveland, Ohio sits within the traditional U.S. manufacturing belt and hosts multiple established injection molders with decades of experience, advanced certifications, and diverse capabilities ranging from micro-molding to heavy wall production. All three Cleveland-area companies are located within the greater metropolitan area (15-30 miles from downtown), reflecting typical industrial park locations. The New Orleans metropolitan area has no local injection molding facilities; the nearest companies are concentrated 130-330 miles away in Lafayette, Grand Coteau, and Bossier City. This reflects Louisiana’s stronger focus on petrochemical and energy industries rather than precision manufacturing. Urban Honolulu represents a complete manufacturing gap: Hawaii’s isolation creates prohibitive logistics costs for plastic injection molding operations, forcing local businesses to source from mainland suppliers. Companies verified in this research demonstrated clear specializations (Noble Plastics in defense and solar, ASH Industries in medical and aerospace, Raytech Industries in engineering-grade polymers, Automation Plastics in gas distribution components), reflecting the industry trend toward niche expertise rather than general-purpose molding services.
