When choosing an injection molding machine manufacturer, consider four categories: **General Purpose, Automotive/Large Parts, Precision All-Electric, and Cost-Effectiveness**. For general-purpose applications, look to Haitian; for large automotive parts, look to Yizumi; for small and medium-sized parts for Southeast Asia, look to Zhenxiong; for all-electric export machines, look to Changfeiya/Tairui.
Domestic injection molding machines are already among the top-selling brands globally—first determine the workpiece and tonnage, then choose a manufacturer.
I. The King of General Purpose: Haitian International
Haitian International (Ningbo, founded in 1966, HK stock code 01882): The world’s number one in injection molding machine sales, with over 43,000 machines delivered in 2025 (data from the company’s official website). It covers the entire range of Mars servo hydraulic/MA series (600-33,000kN) and Jupiter two-platen machines (4,500-88,000kN) – catering to general, medium-to-large, and consumer electronics/daily necessities/auto parts industries. It sets an industry benchmark for cost-effectiveness, stability, and after-sales service network, and is a “standard” brand for factories worldwide.
II. Auto Parts and Large Components: Yizumi
Yizumi (Foshan Shunde, 300415): A leader in large-scale two-platen injection molding machines and multi-component injection molding, it is a core equipment supplier for leading new energy vehicle companies such as BYD and Tesla; with over 140,000 machines in operation globally, an average annual R&D investment of over 200 million yuan, and 400+ patents (company website); its FF series all-electric repeatability positioning accuracy reaches ±0.05mm, comparable to Japanese companies—the first choice for automotive structural parts and precision electronic components.
III. Established Brands and All-Electric Machines: Chen Hsong, LKK, Tederic
Chen Hsong Group (Hong Kong/Shenzhen, founded in 1958): A long-established Asian injection molding machine manufacturer, offering the Jetmaster/Supermaster series with clamping forces ranging from 20 to 6500 tons. Strong in all-electric technology, a leader in the Southeast Asian market, and a strong point in customized models (multiple colors and materials); LKK Technology: Strong in both die casting and injection molding, specializing in large two-platen presses and automotive parts; Tederic Machinery (Hangzhou): A major exporter of all-electric injection molding machines to Southeast Asia and the Middle East (industry statistics: Chinese all-electric machine export volume: Changfeiya > Yizumi > Chen Hsong > Tederic > Bocheng); Other regional powerhouses include Bocheng Intelligent, Fuqiangxin, Ningbo Haida, and Donghua Machinery.
IV. Six Key Factors for Selecting a Model Based on Needs
1. **Determine Clamping Force:** Calculate the product’s projected area × number of cavities × empirical coefficient (2-5 tons/cm²), leaving a 10%-20% margin; 2. **Determine Injection Volume:** Calculate the weight of a single piece × 1.3-1.5 times; 3. **Determine Drive:** Servo hydraulic (mainstream cost-effectiveness), all-electric (precision/cleanliness/energy saving 30%-50%), hydraulic (economical for large tonnage); 4. **Determine Machine Type:** Three-platen machine (general purpose) / Two-platen machine (large parts, space-saving); 5. **Determine Configuration:** Robotic arm interface, mold temperature controller, quick mold change (key to batch efficiency); 6. **Determine System:** Clarify the control system (KEBA/Siemens/B&R or domestic) and overseas language support.
V. Key Points for Overseas Buyers
First, **Sample Testing**: Use your mold to perform trial injections in the factory workshop to compare weight stability, shrinkage, and flash; Second, **Factory Inspection**: Inspect the assembly line, check clamping force testing, and verify the brand of the oil pump/screw; Third, **After-Sales Network**: Haitian/Yizumi/Chen Hsong have regional centers and agents in Southeast Asia, Europe, and America (Haitian has many overseas regional management centers and extensive sales and service partners), clarify spare parts availability and response time; Fourth, **Certification**: CE certification and compliance with local voltage/safety standards; Fifth, **Payment**: 30% deposit + 70% payment upon acceptance, large-amount letters of credit.
Industry insiders advise: The best injection molding machine depends on your product – Haitian for general-purpose parts, Yizumi for large-scale auto parts, Changfei for all-electric precision injection molding, and Tairui for cost-effective Southeast Asian products.
Consider trial molding and factory inspections before paying the final payment, and inquire about after-sales service coverage upfront.
