Introduction
HERZOG (CHINA) CO., LTD. (Chinese: 和卓喷嘴阀门系统（宁波）有限公司) is the China-based subsidiary of the Swiss Herzog group, a manufacturer specialized in needle shut-off nozzles and related components for injection molding and elastomer processing. The company is based in Ningbo, Zhejiang, and its China presence is used to serve injection molding machinery builders and plastics processors in the Asian market with nozzle systems, special nozzles, and components for gas- and water-injection technologies.
In the plastics industry, Herzog China occupies a niche focused on precision nozzle technology rather than broad polymer processing equipment. Its core offer centers on shut-off nozzle systems designed for thermoplastic and elastomer applications, with actuation options that include pneumatic, hydraulic, electric, and spring mechanisms. Chinese industry listings also identify the company as a manufacturer of injection-molding nozzle and valve systems and related parts.
History and Development
Herzog’s broader corporate history dates to 1969, when the Swiss business was founded and later concentrated on nozzles and components for the plastics sector. The company states that its needle shut-off nozzles became its core activity over subsequent decades, supported by in-house research and development and Swiss production.
A major step in internationalization was the establishment of a China branch in the mid-2000s, with Herzog materials noting the opening of the China subsidiary in 2005 and the launch of its Ningbo operation in 2007. Company materials describe this move as part of a broader Asian strategy that aimed to combine European engineering standards with local market proximity and service.
More recently, Chinese government innovation and technology lists have repeatedly included the Ningbo company among technology-oriented small and medium-sized enterprises and high-tech enterprise-related records, indicating continued recognition within local industrial policy frameworks.
Business Operations and Structure
Herzog China functions as part of a wider family-owned industrial group with sales and technical support centered on customer proximity and application engineering. Public contact listings show the company operating from Ningbo and maintaining local management and sales-technical leadership for the China market.
The company’s business model is oriented toward:
- Injection molding machinery manufacturers
- Plastic processors
- Users requiring specialized nozzle and shut-off solutions for demanding molding processes
Herzog’s published materials emphasize technical consultation, service support, and solution tailoring rather than mass-market commodity supply. In effect, the China subsidiary serves as a regional access point for a specialized European nozzle technology platform.
Products and Technologies
Herzog China’s principal products are needle shut-off nozzles for thermoplastic and elastomer processing. These nozzles are intended to control melt flow with a shut-off needle, helping reduce drooling and improve process control in injection molding applications.
Reported product and technology areas include:
- Needle shut-off nozzles
- Plunger-type shut-off nozzles
- Special nozzles
- Components for gas injection and water injection technologies
The company states that its shut-off mechanisms may be spring-, pneumatic-, hydraulic-, or electrically actuated, allowing adaptation to different machine architectures and process requirements. Herzog also describes its products as being designed through detailed engineering and precision manufacturing, with emphasis on durability and process-specific design.
From an industrial perspective, this product category is important because nozzle performance can affect:
- Melt sealing and flow consistency
- Cycle stability
- Material savings through reduced drool and waste
- Compatibility with high-viscosity or demanding thermoplastic and elastomer applications
Applications and End Markets
Herzog China serves applications within injection molding and related plastics processing, particularly where controlled melt shut-off is required. The company’s stated customer base includes:
- Machine builders
- Plastic processors
- Users of gas-assisted and water-assisted injection technologies
Company materials also suggest a relationship with broader industrial manufacturing through the emphasis on precision engineering and process stability, although the company’s public profile is primarily centered on plastics processing equipment rather than downstream consumer goods sectors.
Global Presence and Market Position
Herzog’s China subsidiary is part of a small international footprint that includes Switzerland as the corporate and engineering base, with China as a key regional market. The company’s own materials describe the family business as one of the early suppliers of shut-off nozzles and as an established specialist in this field.
The China operation is located in Ningbo, a major industrial center in Zhejiang province with strong plastics manufacturing and machinery supply chains. This location supports access to domestic machinery builders, molders, and technical service networks.
Public materials do not provide verifiable market share data, so Herzog China’s market position is best characterized as a specialist supplier in a narrow but technically important segment of injection molding hardware.
Sustainability and Environmental Considerations
No public sustainability report specific to Herzog China was identified in the supplied sources. However, the company’s product category intersects with sustainability trends in plastics manufacturing because higher-precision nozzle control can support process efficiency, reduce material loss, and improve repeatability in molding operations.
At the same time, the company operates within the broader plastics industry, where environmental scrutiny centers on resource use, process efficiency, and end-of-life impacts. Herzog’s public materials emphasize engineering precision and process optimization rather than direct environmental claims.
Financial Performance and Economic Impact
No audited financial statements or revenue figures for Herzog China were identified in the provided material. The available evidence instead shows the company as a specialized manufacturing and technical-services entity embedded in the Chinese plastics supply chain.
Its economic contribution is best understood through:
- Local manufacturing and service activity in Ningbo
- Technical support for injection molding operations
- Participation in China’s advanced manufacturing ecosystem, including recognition in technology-oriented enterprise lists
Leadership and Corporate Governance
Public contact and networking pages identify Joe Shen as Managing Director of Herzog China and Cyril Liang as Director of Sales and Technology. These listings indicate a locally managed structure aligned with the company’s customer-facing and technical-sales model.
The parent group is presented as a family-owned business with longstanding engineering specialization, and company materials stress internal R&D, quality focus, and service orientation.
Innovations and Future Outlook
Herzog’s innovation profile is centered on application-specific nozzle engineering rather than broad portfolio expansion. The company emphasizes precision design, process adaptation, and support for advanced injection technologies such as gas and water injection.
Likely future themes for the business include:
- Continued support for high-precision injection molding
- Greater localization of service in China
- Integration of nozzle systems with more automated molding environments
- Ongoing adaptation to efficiency, quality, and process-consistency demands in plastics manufacturing
Summary
Herzog (China) Co., Ltd. is a specialized Chinese subsidiary of the Swiss Herzog group, focused on needle shut-off nozzle systems for injection molding and elastomer processing. Its significance lies in precision engineering, local technical support in Ningbo, and its role in supplying machine builders and processors with specialized melt-control components for demanding plastics applications.
