China Extruder Manufacturers

In the first half of 2021,the total import and export value of 12 key plastic machinery in mainland China was nearly US$2.880 billion, up 49% year on year, according to statistics from the General Administration of Customs of China. The import value amounted to US$1.107 billion, rising 40% year on year. The export value of extruders grew faster than import value, with the export value increasing by 23% year on year. The export value and import value of injection blow molding machines increased by 25% and 45% respectively year-on-year.

The design of China’s extruder moves to energy saving and environmental protection. The mainstream trend of the extruder machine industry development goes to specialization, personalization, serialization, standardization, compounding, miniaturization, massification, intelligence, automation, energy-saving, material saving, efficiency and environmental protection.

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

Screw extruders use the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix materials. More than 75% of all screw products in China come from Jintang town, Zhoushan city, Zhejiang Province, which is known as the “screw base of China”.

Zhoushan Jintang plastic machine screw industry was included in the key support projects for industrial quality improvement in Zhejiang Province. Recently, Nitriding Single-screw and Barrel for Plastic Machinery has been officially released as association standards, the drafting of which was led by Zhejiang Huaye Plastic Machinery Co., Ltd. This marks the basic realization of the full coverage of the standard in Jintang’s plastic machine screw industry.

Jintang’s screw industry adopts 4 group standards of Zhengjiang manufacturing including Screw of Full Hard for Plastics Machinery, Conical Counter-rotating Twin Screw and Barrel for Plastics Extruder, etc, covering almost all types of screws for plastics machinery. Moreover, Jintang’s screw industry adopts Single-screw and Barrel for Plastic Machinery and Twin-screw and Barrel for Plastic Machinery as association standards and Screw and Barrel for Plastic Machinery (JB/T 8538-2011) as industry standards. Jintang’s screw industry now has a multi-stepped and full-covering standard system consisting of “Zhengjiang made” group, association and industry standards, which provide standard support for the high-quality development of the screw industry.
