Introduction
Suzhou CAIVI Plastic Machinery Co., Ltd. (苏州凯威塑料机械有限公司) is a Chinese manufacturer of plastic extrusion, recycling, washing, pelletizing, and auxiliary machinery based in Zhangjiagang, Jiangsu Province. The company serves processors involved in plastics conversion and recycling, with product lines that include pipe extrusion lines, recycling and pelletizing systems, washing lines, shredders, and related auxiliary equipment.
CAIVI is positioned within the plastics machinery segment of the wider plastics industry, where equipment makers supply the process technologies used to transform virgin or recycled polymer feedstock into pipes, pellets, pallets, and other downstream products. Its published materials emphasize high automation, stable operation, energy efficiency, and process control, particularly in systems designed for PP/PE, PVC, PPR, PEX, PET, and mixed waste-plastic recovery.
The company appears in the CHINAPLAS exhibitor directory, underscoring its participation in major regional plastics-industry trade activity and its visibility among machinery suppliers in the Chinese market.
History and development
Publicly available sources suggest that CAIVI was established in the mid-2000s, with third-party business directories giving founding dates in 2005 and 2008; the discrepancy likely reflects inconsistent directory data rather than a confirmed reorganization date. The company’s online presence indicates long-running engagement in plastics machinery manufacturing and export-oriented sales activity.
A few development milestones are identifiable from the available materials:
- CAIVI built its business around extrusion and recycling machinery, including single- and multi-screw extruders, recycling systems, and auxiliary equipment.
- The company expanded into complete process lines for pipe production and waste-plastic recovery, rather than limiting itself to stand-alone machines.
- More recent exhibition and news materials show continued participation in industry events, including CHINAPLAS 2026, which suggests sustained commercial activity in both domestic and export markets.
Business operations and segments
CAIVI’s operations are centered on the design and manufacture of machinery for plastic processing and recycling. Its product portfolio shows two broad business segments:
- Processing and extrusion equipment, including pipe extrusion lines and related extrusion systems.
- Recycling and resource-recovery systems, including washing, shredding, and pelletizing lines for post-consumer and post-industrial plastics.
The company’s published materials and marketplace listings also suggest an emphasis on turnkey or semi-turnkey production lines, which is typical of machinery suppliers serving processors that require integrated material handling, cleaning, melting, filtration, and downstream forming capabilities.
Products and technologies
CAIVI’s product range covers several machinery categories used across the plastics value chain:
| Product category | Typical use | Technical notes from available materials |
|---|---|---|
| Plastic pipe extrusion lines | Production of PEX, PE, PVC, PPR, HDPE and related pipes | The company states that its systems are designed for stable operation, high output, low energy consumption, precise temperature control, and dimensional accuracy. |
| Recycling and pelletizing lines | Conversion of PP/PE film, sheet, and other waste plastics into pellets | CAIVI describes PID temperature control and automatic high-efficiency filtration as part of the process. |
| Plastic washing and recycling lines | Cleaning and sorting of PP/PE/PET waste streams | The process includes crushing, cleaning, and sorting to remove impurities before pelletizing. |
| Waste plastic pallet production lines | Production of plastic pallets from recycled PP/PE material | The company emphasizes automation, lower labor demand, and high-strength finished pallets. |
| Shredders and auxiliary equipment | Size reduction and support functions | Directory listings identify single-shaft shredders, while the company also markets dryers, feeders, crushers, and chillers. |
One product area of particular technical relevance is CAIVI’s waste-plastic extrusion and molding equipment, which industry event coverage describes as using two-stage extrusion plus compression molding, with wear-resistant alloy steel in key parts and PLC control with PID temperature regulation. That configuration is consistent with equipment designed for converting recovered plastics into higher-value structural products.
Applications and end markets
CAIVI’s machinery is aimed at processors serving several end markets:
- Water supply and drainage pipe manufacturing
- Municipal infrastructure
- Home decoration and building systems
- Plastic recycling and resource recovery
- Logistics and industrial pallet production
- Environmental materials and recycled products manufacturing
Its pipe machinery is specifically described as suitable for pipe applications used in water supply, drainage, municipal, and home-decoration scenarios, while its recycling lines are positioned for the recovery of post-consumer film, bottles, sheets, and mixed waste plastics.
Global presence and market position
CAIVI is headquartered in Zhangjiagang, a major plastics machinery cluster in Jiangsu Province with convenient access to the Shanghai economic region and export logistics corridors. This location places the company within one of China’s established manufacturing ecosystems for plastics processing equipment.
The company appears to maintain a sales and export-oriented profile, with marketplace listings, trade platforms, and contact directories indicating international trade activity and machinery export support. Its presence in exhibition databases and trade directories suggests that it competes in the dense Chinese plastics machinery market primarily as a specialized equipment supplier rather than as a large integrated conglomerate.
Sustainability and environmental initiatives
CAIVI’s sustainability narrative is centered on plastic recycling and high-value resource recovery. The company repeatedly frames its washing, pelletizing, and pallet-production lines as tools for turning waste plastics into reusable feedstock or finished goods.
Its website materials highlight several environmental and operational benefits:
- Reduced waste through recycling and reprocessing of PP/PE, PET, and other polymer streams.
- Energy-saving processing, supported by temperature control and filtration systems.
- High-value recycling, including the conversion of waste plastics into pallets and pellets for downstream manufacturing.
At the same time, CAIVI’s activities should be viewed in the context of the broader plastics industry, where recycling systems are increasingly important but remain dependent on feedstock quality, contamination control, and end-market demand for recyclate.
Financial performance and economic impact
No audited financial statements or verified revenue figures were identified in the available sources. On the basis of public materials alone, CAIVI appears to operate as a mid-sized machinery manufacturer serving both domestic and export customers through standard product lines and custom-engineered systems.
Its economic role lies in supplying machinery that supports:
- Plastic manufacturing capacity
- Recycling and circular-economy infrastructure
- Local employment in Zhangjiagang’s machinery cluster
- Equipment exports linked to Asian, Middle Eastern, African, and Latin American markets, as implied by trade and exhibition references.
Leadership and corporate governance
Publicly available sources provide limited formal governance information. The company’s contact and sales materials identify trade and sales personnel, but do not provide a full board structure or management disclosure comparable to a listed corporation.
The company’s English-language materials emphasize a business philosophy centered on customer service, technical support, and quality manufacturing, while Chinese-language descriptions refer to advanced production equipment and inspection systems. These statements are promotional in character, but they indicate a corporate focus on manufacturing reliability and after-sales support.
Innovations and future outlook
CAIVI’s most visible innovation themes are automation, integrated recycling lines, and process control. The company’s product descriptions repeatedly stress:
- High automation
- Stable output
- Low energy consumption
- Precise temperature control
- Automatic filtration and cleaning
- Turnkey recycling-to-product workflows
These are all relevant capabilities in a plastics industry increasingly shaped by regulatory pressure, recycled-content demand, and the need to improve the economics of waste-plastic processing. Future growth for firms like CAIVI is likely to depend on continued refinement of recycling-line efficiency, compatibility with mixed and contaminated feedstocks, and the ability to supply complete systems that reduce operating complexity for processors.
