The ranking of plastic machinery manufacturers is based on three criteria: overall strength, specific machine types (injection molding/extrusion/blow molding/auxiliary equipment), and specific market segments. The top tier overall consists of Haitian, Kingway, Chen Hsong, and Yizumi, with leading manufacturers in each specific machine type.
For overseas buyers to choose a manufacturer, the ranking is only meaningful if they first select the machine type.
I. Comprehensive Strength Ranking: First Tier
Selection of Leading Enterprises in China’s Plastics Machinery Industry (China Plastics Machinery Industry Association, ranked by main business revenue and net profit): Haitian International (Ningbo): Ranked first in both comprehensive strength and injection molding machines; number one in global sales; over 43,000 units delivered in 2025; Jinwei Machinery (Shanghai): Ranked first in the plastic extrusion molding industry for 15 consecutive years; exports to over 120 countries; Zhenxiong Group (Hong Kong/Shenzhen, founded in 1958): A long-established Asian brand; clamping force covers the entire range from 20 to 6500 tons; Yizumi (Foshan Shunde, 300415): Strong in large two-platen extruders/all-electric/multi-component machines; over 140,000 units in operation globally; followed by L.K. Technology, Bocheng Intelligent, Tairui Machinery, Fuqiangxin, and Xinyi Group (the leading brand of plastic auxiliary equipment), etc.
II. Ranking by Machine Type: Who is the King of Which Line?
Injection Molding Machines: Haitian ranks first, followed by Chen Hsong/Yizumi/LK/Bortron/Terrey (All-electric export ranking: Changfeiya > Yizumi > Chen Hsong > Tertron > Bortron); Extruders: Kingway has been ranked first for 15 consecutive years, Dalian Rubber is second, Jiangsu Bell/Shandong Tongjia are in the top ten (for twin-screw modification, look to Nanjing Keya/Ruiya); Blow Molding/Blow Molding: Suzhou Tongda (top three in the industry), Shandong Tongjia, Jinming Machinery (for PET bottle blowing, look to Dayilong, Zhangjiagang cluster); Plastic Auxiliary Equipment (Dehumidification/Drying/Conveying): Xinyi Group “China’s No.1 Brand of Plastic Auxiliary Equipment”; Film Equipment: Jinming Machinery (multi-layer co-extrusion up to 11 layers), etc.
III. Industrial Clusters: Production Capacity Map
Ningbo/Hangzhou: Core injection molding machine cluster (Haitian, Chen Hsong Ningbo Base, Tairui, Bocheng), accounting for approximately half of the national injection molding machine production capacity; Shanghai/Suzhou/Zhangjiagang: Extruder and blow molding equipment cluster (Jinwei, Tongda, Zhangjiagang blow molding cluster); Foshan/Shunde: Yizumi, Chen Hsong South China Base, strong in auto parts injection molding; Shantou: Jinming Machinery film equipment; Qingdao/Shandong: Tongjia (Jining), Aucma series plastic machinery.
Procurement from nearby locations can reduce logistics and after-sales costs.
IV. How Overseas Buyers Use Ranking Lists
First, **select ranking lists by machine type**:** For injection molding, look at the comprehensive ranking list; for extrusion, look at the extrusion ranking list; for blow molding, look at the blow molding ranking list—do not use the comprehensive ranking list to select extruders; Second, **initial screening of ranking lists + configuration comparison**:** Select 3-5 companies and have each company report their configuration and price based on your product (material/weight/output); Third, **trial production and mold testing**: Use your raw materials/molds to conduct trial production in the manufacturer’s workshop to verify output and quality; Fourth, **factory inspection and service assessment**: Overseas network, spare parts, remote diagnostics (Haitian/Jinwei/Zhenxiong have extensive overseas network coverage); Fifth, **contract finalization**: Write the cycle time/precision/energy consumption into the acceptance clauses, with a 30% deposit + 70% payment upon acceptance.
V. Tips to Avoid Pitfalls
First, **overall ranking ≠ suitable:** Haitian is ranked first in injection molding, but for extrusion lines, choose Kingway—match the machine model accordingly; Second, **be wary of refurbished/downgraded equipment:** Request factory inspection reports, serial numbers, and a list of brands for core components (servo/screw/temperature control); Third, **don’t neglect auxiliary equipment:** Auxiliary equipment such as dehumidifiers, dryers, and conveyors (like Xinyi) determines the stability of the entire plant; don’t just focus on the main machine.
Industry insiders remind you: Plastic machinery rankings provide “who’s bigger and stronger,” but the answer to purchasing lies in “machine model + trial run + service”—for injection molding, choose Haitian, Zhenxiong, and Yizhimi; for extrusion, choose Kingway; for blow molding, choose Tongda Tongjia; for auxiliary equipment, choose Xinyi.
Match the machine model, conduct trial runs and factory inspections before paying the final payment.
