Injection Molding Statistics 2026

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.

How big is the US plastics manufacturing industry?

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?

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?

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

What is the average injection mold technician wage?

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?

What share of new injection presses are all-electric?

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.

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.
