<UpdatedDate date="2026-06-02" readingTime="~10 min read" />

The plastics industry, including injection molding, extrusion, blow molding, thermoforming, and compounders, is the third-largest manufacturing sector in the United States by employment. Injection molding alone represents the largest share of that workforce and capacity.

<KeyTakeaways>

- US plastics manufacturing generates roughly $430 billion in annual shipments and supports about one million direct jobs.
- Injection molding specifically accounts for an estimated $40 billion to $50 billion in US shop revenue.
- Custom injection molders number around 5,500 in the US, with most operating fewer than 50 employees.
- Automotive, packaging, medical, and consumer products drive the bulk of injection molding demand.
- All-electric presses now account for over 40% of new machine orders.

</KeyTakeaways>

## How big is the US plastics manufacturing industry?

<StatSnippet value="$430B" source="Plastics Industry Association, 2024" sourceUrl="https://www.plasticsindustry.org/research-data">
US plastics manufacturing annual shipments.
</StatSnippet>

<StatSnippet value="1M" source="PIA, 2024" sourceUrl="https://www.plasticsindustry.org/research-data">
Direct US plastics manufacturing employment.
</StatSnippet>

US plastics manufacturing covers every form of plastic conversion, with injection molding the largest single segment by revenue and employment. The industry directly employs about one million workers across roughly 16,000 establishments.

## How many custom injection molders are in the US?

<StatSnippet value="~5,500" source="Industry estimates, 2024" sourceUrl="https://www.plasticsindustry.org/research-data">
US custom injection molding shops as of 2024 industry estimates.
</StatSnippet>

Captive molding operations inside larger OEMs (automotive parts makers, appliance manufacturers, medical device companies) account for additional but unmeasured capacity. Most custom molders run 20 to 80 presses, though tier-1 automotive molders operate 200-plus press facilities.

## What end markets drive US injection molding demand?

<BarChart title="Estimated share of US custom injection molding revenue by end market, 2024" unit="%" series="Automotive:24|Packaging:22|Medical and pharma:15|Consumer products:11|Electrical/electronics:9|Industrial/MRO:8|Construction:6|Other:5" />

Injection molded parts touch nearly every consumer-facing product. Four core end markets together account for roughly 70% of US custom-mold revenue.

<Callout type="insight" title="The medical molder advantage">

Medical injection molders work to ISO 13485 and FDA standards, run validated processes, and serve customers with multi-year design cycles. Medical work pays better margins than commodity automotive but demands tighter quality systems and longer sales cycles.

<StatSnippet value="$95,000" source="BLS / industry, 2024" sourceUrl="https://www.bls.gov/oes/current/oes514111.htm">
Median annual wage for US toolmakers, including injection mold builders.
</StatSnippet>

Plastics manufacturing wages have climbed substantially over the last three years. Process engineers and program managers typically sit between $75,000 and $130,000. Senior toolmakers in aerospace or medical clear $100,000.

## Which states have the most plastics manufacturing?

<DataTable caption="Top states by plastics manufacturing employment, 2024">

## What share of new injection presses are all-electric?

<StatSnippet value="40%+" source="Plastics Machinery Manufacturers Association, 2024" sourceUrl="https://www.pmmainc.org/">
Share of new North American injection press orders that are all-electric, displacing hydraulic.
</StatSnippet>

<StatSnippet value="~6,000" source="PMMA, 2024" sourceUrl="https://www.pmmainc.org/">
Annual North American injection molding machine shipments.
</StatSnippet>

All-electric machines run quieter, use less energy, and offer better repeatability than hydraulic, which makes them the default choice for medical, optical, and tight-tolerance work.

## How fast is automation expanding in injection molding?

Robotic part removal is now standard equipment on most new injection presses. End-of-arm tooling has matured enough that shops can switch jobs in under 30 minutes for many runs. Lights-out molding, where presses run unstaffed overnight using vision-system quality control and automated stacking, is mature in large shops and growing in mid-size shops.

<StatSnippet value="60%+" source="Industry survey, 2024" sourceUrl="https://www.pmmainc.org/">
Estimated share of mid-to-large US injection molders running lights-out shifts as of 2024.
</StatSnippet>

<PullQuote source="Plastics Industry Association, 2024 Size and Impact Report">
US plastics manufacturing has added more than 110,000 jobs since 2017, reversing two decades of slow decline as reshoring and medical demand pulled capacity back to North America.
</PullQuote>

## What does this mean for molders in 2026?

The competitive picture rewards specialization. Generalist molders without process expertise in a defined end market increasingly lose work to shops with vertical focus. Medical molders with cleanroom capacity and ISO 13485 certification win disproportionate share. Automotive molders with PPAP discipline and validated processes win the long programs. Consumer molders with fast tooling and packaging finishing capabilities win the volume work.
