Business Operations and Segments
Ningbo Haijiang’s core business is the design, manufacturing, and sale of injection molding machinery. The company also advertises related offerings in moulds, blow molding machines, and auxiliary equipment, indicating a machinery-centered model that extends across parts of the plastics processing workflow.
Its operations appear to combine manufacturing with export-oriented sales and customization. Public descriptions refer to one-stop customized solutions, automated assembly and testing support, and long-term cooperation with clients in sectors such as 3C electronics and new energy. This suggests that Haijiang does not merely sell standard machines but also supports application-specific system integration.
The company’s business scope is consistent with a mid-sized industrial equipment producer:
- Machine manufacture for thermoplastic molding
- Process specialization in energy-saving and high-speed systems
- Custom engineering for niche applications
- Export sales through multilingual and international channels
Products and Technologies
Haijiang’s product range centers on plastic injection molding machines with multiple process variants. Publicly listed product families include:
- Energy-saving injection molding machines using servo or variable-displacement pump systems
- PET preform injection molding machines for beverage and packaging applications
- Thin-wall container high-speed machines for fast-cycle packaging production
- Double-color / bi-color machines for multi-material or multi-color parts
- PVC pipe fitting machines for building materials and plumbing components
- Vertical injection molding machines for insert molding and compact production layouts
The company’s technical descriptions point to a broad equipment envelope, with machine capacities reported from 50 tons to 1,680 tons on some listings, and clamping-force ranges extending up to 15,000 kN on others. The machinery is described as computerized, automatic, and based on screw-type plasticizing systems, with hydraulic and mechanical clamping arrangements appearing in product listings.
