Introduction
KONRUN INTELLIGENT MACHINERY (NINGBO) CO., LTD. is a Chinese manufacturer of plastic extrusion machinery and related downstream equipment, headquartered in Yinzhou District, Ningbo, Zhejiang Province, China. The company presents itself as a producer of extrusion lines for pipes, profiles, plates and sheets, cast film, and related single-screw and twin-screw extruders, along with washing and recycling pelletizing lines and auxiliary equipment for plastics processing.
Within the plastics industry, KonRun is positioned in the machinery and equipment segment rather than in polymer production or plastic compounding. Its stated focus on extrusion technology, process integration, and customer-specific mechanical design places it in the supply chain that converts polymer raw materials into finished or semi-finished plastic products used across construction, packaging, and industrial applications.
The company describes its development strategy as combining European extrusion technology with in-house design and fabrication, emphasizing high-precision control, efficient extrusion, and manufacturing quality. Publicly available exhibitor listings also identify the firm as a specialized and sophisticated enterprise in China’s industrial policy framework, including recognition as a “Little Giant”-type enterprise, which typically denotes a smaller firm with specialized technical capability and niche market relevance.
History and Development
KonRun’s own company materials state that it was built around a production base in Ningbo’s Yinzhou area and developed through long-term work in plastic machinery research and development. The company’s public-facing materials also show an established service and contact network in Ningbo and a related industrial base in Jiangsu, indicating expansion beyond a single-site operation.
Key development milestones visible in the available sources include:
- Formation of a dedicated manufacturing base in Ningbo and the establishment of internal functions such as sales, technical center, extrusion department, quality control, and product testing.
- Broadening from core extrusion machinery into recycling-related lines such as washing and pelletizing systems, reflecting a shift toward circular-economy processing equipment.
- International exhibition participation and export-oriented marketing, including repeated exhibitor and supplier video listings on ChinaPlas and other trade platforms, indicating an outward-facing commercial strategy.
Business Operations and Segments
KonRun’s business appears centered on the design, manufacture, and support of complete plastics processing lines. Its main operational areas include:
- Extrusion systems for pipe, profile, board, sheet, and cast film production.
- Recycling and pelletizing lines, including washing and soft plastics recycling equipment.
- Single-screw and twin-screw extruders, which serve as core process machines for melting, conveying, mixing, and shaping thermoplastic materials.
- Downstream and auxiliary equipment, including cutting systems and packaging-related machinery.
The company also states that it maintains a customer service function that covers consulting, technical support, complaint handling, and after-sales coordination, suggesting a project-based business model in which machine delivery is followed by installation, commissioning, and support.
Products and Technologies
KonRun’s product portfolio is built around extrusion-line engineering and associated process modules. The company’s English-language materials identify the following major product categories:
- Plastic pipe extrusion lines
- Plastic profile extrusion lines
- Plastic plate and sheet extrusion lines
- Cast film extrusion lines
- Single-screw extruders
- Twin-screw extruders
