Notes
Jacksonville, FL presented significant research challenges with limited dedicated local plastic injection molding companies. The search returned primarily directory listings, SEO landing pages from out-of-state companies, and offshore manufacturing services. Only 2 companies with verified Jacksonville addresses and active plastic injection molding operations were confirmed: S. Gager Industries (a smaller family operation) and Plastic Concepts & Design (established in 1989).
Austin, TX has limited local plastic injection molding presence. Only 2 verified companies were found within the 50-mile radius: Medway Plastics operates a 51,000 sq ft facility in Round Rock (15 miles north of Austin), and Deep South Plastics provides injection molding services from Austin. Several companies serve the Austin market from Houston (approximately 150 miles away), but these fall outside the search radius.
Fort Worth, TX demonstrated the strongest concentration of verified local plastic injection molding companies among the three cities. All three companies (Superior Plastics, Micro Mold Plastics USA, and C&S Custom Plastics) are established local manufacturers with verifiable addresses, active websites, and documented industry certifications. The aerospace and defense certifications held by Superior Plastics and Micro Mold Plastics USA reflect the DFW region’s strong ties to those industries.
