Global Geographical Distribution Of Extruder Manufacturers
Extruder manufacturers mainly concentrate in North America, Europe, Japan and China.
In recent years, emerging manufacturing hubs such as India, Southeast Asia, and Türkiye have been gaining importance, especially in cost-sensitive and regional markets.
The global twin-screw extruder market has steadily expanded over the past few years. In 2023, the market size was approximately USD 2.88 billion, growing to around USD 2.99 billion in 2024 and USD 3.14 billion in 2025, and reaching approximately USD 3.25 billion in 2026. The growth has been primarily driven by increasing demand from plastics and polymer processing, construction materials production, advanced compounding technologies, and the rising adoption of high-performance materials in consumer and industrial applications. The twin-screw extruder segment continues to benefit from technological innovation, including energy-efficient designs, precise process control, and multi-material processing capabilities.
China, as the world’s second-largest economy, has played a leading role in the twin-screw extruder market. In 2026, China’s twin-screw extruder output accounts for a significant share of the global market, driven by both export expansion and domestic demand. Alongside China, other notable regional markets include Japan, Germany, and Canada, which have maintained steady growth, with Germany and Japan leading in high-end, specialized extruder technologies, and North America focusing on precision and automation in extrusion processes.
China Extruder Manufacturers
China has been one of the world’s leading exporters of plastic extrusion machinery, including twin‑screw and other extruder types. Historical trade statistics show strong export performance: in the first half of 2021, the total import and export value of 12 key categories of plastic machinery in mainland China reached nearly USD 2.88 billion, with extruder exports growing faster than imports during that period. From January to November 2022, China imported about 1,000 extruders but exported 109,000 units, reflecting significant outbound shipments. In the first half of 2023, the export value of extruders was USD 362.9 million, maintaining year‑on‑year growth.
More recent trade data indicate that in 2024, China’s extruder export value reached approximately USD 925 million, accounting for about 25% of global plastic extruder exports, with export volume representing around 58% of total global units shipped. This sustained export footprint underscores China’s long‑term expansion in production capacity and global competitiveness. Improvements in machine quality, coupled with increasingly comprehensive after‑sales services — such as preventive maintenance, remote diagnostics, and rapid response support — have enhanced the appeal of Chinese extruders in international markets.
Nanjing-China's Twin Screw Extruders Manufacturing Base
Nanjing, home to many extruder manufacturers, has the name “base of extruders” in China. Most of the companies here are small-scale enterprises. The shake-up of the industry has never stopped, and the extruder manufacturers keep evolving their technology and updating their service consciousness. The aftersales service that used to be door-to-door maintenance when machines get something wrong has turned into comprehensive services including preventive maintenance, in order to provide maximum help for users.
The extruder manufacturing technology in Nanjing is so sophisticated that the quality of extruders in Nanjing can definitely be guaranteed if you want to import Chinese extruders. Your main concern should be focused on service. You’d better choose companies that have been established for a long time as they survive the test of time and fierce competition. With years of export experience, they know the importance of service, hence, they have a strong sense of service and a high degree of credibility.
Some extruder manufacturers are now capable of offering complete extrusion lines and can even undertake turnkey projects. Their advantages lie in cost-effectiveness and fast service, which enable them to compete with medium and large companies. These manufacturers are the best choice for small and medium-sized enterprises in plastics production.
Jintang, Zhoushan, China's Screw Base
As a core piece of equipment in plastics processing, screw extruders rely on the pressure and shear generated by the screw’s rotation to fully plasticize and uniformly mix materials. Over 75% of all screw products in China originate from Jintang Town, Zhoushan City, Zhejiang Province, earning the area the nickname “China’s Screw Base.”
The industry has been designated as a key support project for industrial quality improvement in Zhejiang Province. Currently, Jintang has established a multi-tiered, high-standard system encompassing “Made in Zhejiang” group standards, association standards, and national/industry standards, laying a solid foundation for high-quality development. For example, the industry not only follows widely used industry standards such as “Nitriding Single Screw and Barrel for Plastic Machinery” (JB/T 8538-2011), but also actively leads higher standards: core products are produced in accordance with association standards such as “Nitriding Single Screw and Barrel for Plastic Machinery” (T/ZZB 2161—2021), and have pioneered the adoption of advanced “Made in Zhejiang” group standards, including “Screw Of Full Hard For Plastics Machinery”(T/ZZB 0873-2018).
The establishment and implementation of this comprehensive standards system has significantly enhanced the consistency, reliability, and market competitiveness of Jintang’s screw products, continuously driving the local industry toward a new stage of high-end, intelligent manufacturing.
