Introduction
Demag Plastics Machinery (Ningbo) Co., Ltd. is the Chinese manufacturing subsidiary of Sumitomo (SHI) Demag, located in Ningbo, Zhejiang Province, where it produces injection moulding equipment for China and other Asian markets. The company is focused on hydraulic and hybrid injection moulding machines, with its Ningbo plant serving as a regional production and assembly base for high-performance systems used in packaging, automotive, medical, consumer, and precision parts applications.
The company’s presence in China dates to 1988, when it began importing equipment from its German parent to serve the Chinese market, and to 1998, when it became one of the earliest European injection-moulding brands to establish a local factory in China. Its industrial role reflects the broader internationalisation of the plastics machinery sector, in which global equipment makers combine local manufacturing, technical support, and application engineering to serve fast-growing regional processing markets.
History and Development
Demag’s Chinese operations were built on a long German injection-moulding heritage that the company traces back to the start of machine manufacturing in Nuremberg in 1950. In China, the business began with imported equipment in 1988, before establishing local production in 1998 in Ningbo.
A major expansion milestone came with the development of a larger Ningbo plant that was publicly described as a new production and logistics site of about 26,700 square metres with annual capacity of up to 1,000 injection moulding machines. Later company and exhibition materials describe the Ningbo site as a modern factory with roughly 12,420–12,800 square metres of production area on a site of about 26,705–27,000 square metres, reflecting the company’s continued manufacturing consolidation and capacity growth in China.
By 2025–2026, Sumitomo (SHI) Demag described Ningbo as a key production site for the Asian market and emphasized that the Chinese subsidiary is responsible for production-related assembly and commissioning of injection moulding machines.
Business Operations and Segments
The Ningbo company is a wholly owned subsidiary of Sumitomo (SHI) Demag Germany. Its registered business scope includes manufacturing and sales of plastic processing equipment, hydraulic machinery components, rubber processing equipment, industrial robots, mould-related equipment, and related repair, leasing, and agency services.
Operationally, the site combines:
- Manufacturing and assembly of injection moulding machines
- Sales and after-sales service for China and surrounding markets
- Application support and customised solutions for specific end-use sectors
The company’s website also highlights a complete sales and after-sales network and positioning around customised solutions and automation integration.
Products and Technologies
Demag Ningbo’s core products are hydraulic and hybrid injection moulding machines. Its Chinese plant is described as producing machines with clamping forces from 50 tonnes to 1,000 tonnes in one company source, while related exhibition materials refer to a broader portfolio extending to about 1,300 tonnes for Asian market production.
Notable technology and product characteristics include:
- Hybrid drive concepts, including the Systec C SP model, which the company describes as optimized for energy efficiency.
- High-speed precision moulding capability, including equipment used for packaging applications such as thin-wall products and lids.
