As U.S. manufacturers continue to contend with disruptions to the global supply chain, manufacturers are looking to source more supplies at home. One study found that 60% of manufacturers plan to source more supplies domestically in 2022~2023.
The global industrial marketplace continues to see heightened domestic sourcing activity, including greater demand for plastic injection molding services, which reported thousands of searches from industrial buyers interested in plastic injection molding in 2022. Year-over-year category searches on the google were up 30% in 2022, while requests-for-quotes rose 112.71% and catalog downloads increased 31.57%. This trend reflects the growing number of manufacturers looking for domestic supplies, including plastic injection molding companies.
Meanwhile, the global market for injection molded plastics is expected to reach a value of $473.4 billion by the year 2027. Currently, the industry is valued at $339.3 billion.
Today we’re taking a quick look at some additional facts on the plastic injection molding industry and exploring the top ten plastic injection companies in the United States.
Plastic Injection Mold Sector Overview
The plastic injection mold industry is a fairly small and specialized sector with 555 US-based companies. Half of these manufacturers are located in the Midwest.
The practices of this sector closely reflect that of other manufacturers:
• 8% of plastic mold manufacturers import raw materials, which is slightly lower than the 11% average across all manufacturers.
• 76% of plastic mold makers focus on domestic distribution. This is slightly higher than the 70% of all manufacturers that sell their products on the domestic market.
This emphasis on the domestic market and local suppliers could indicate a potential for expansion on new markets for plastic mold manufacturers.
