Introduction
ZHANGJIAGANG CITY GRACE MACHINERY CO., LTD. (张家港市格雷斯机械有限公司) is a Chinese manufacturer of plastic extrusion and plastic recycling equipment based in Zhangjiagang, Jiangsu Province. The company presents itself as an integrated supplier covering design, research and development, production, sales, and service, with a business focus on extrusion systems for piping and profiles as well as recycling and washing lines for post-consumer and industrial plastics.
Grace Machinery is positioned in the midstream plastics machinery segment rather than as a resin producer or processor. Its product scope includes single-screw and twin-screw extruders, downstream auxiliary equipment, pipe extrusion lines, and recycling systems for materials such as PET, PE film, and related waste streams. Company and exhibition listings indicate that it serves export markets and participates in major plastics industry trade platforms, including CHINAPLAS.
History and Development
Grace Machinery was established in 2012, according to multiple business directories and company profile listings. Public filings and local government records also identify the company as a technology-oriented small and medium-sized enterprise in Jiangsu, including recognition as a high-tech enterprise and as a specialized and innovative SME in provincial listings.
Several milestones are evident in the public record:
- 2012 founding and development as an export-oriented plastics machinery maker.
- Expansion into extrusion and recycling systems with a broader portfolio of pipe, profile, washing, and granulation-related equipment.
- Technology upgrading in recent years, including promotion of low-melt-temperature extrusion and large-diameter pipe systems, plus PET recycling lines with high throughput and water recycling functions.
By 2024, the company was publicly associated with advanced production-management methods such as lean manufacturing and MES-based production control, alongside a reported manufacturing site of about 53,000 square meters.

Technical characteristics
Grace Machinery has highlighted low-melt-temperature extrusion technology and a 36L/D parallel twin-screw extruder in company communications, describing these systems as advanced by domestic standards and comparable to international benchmarks. The firm also states that it has experience in large-diameter pipe production, including a φ1600 mm pipe line mentioned in its public materials.
In recycling, the company promotes high-efficiency washing lines with throughput reportedly ranging from 500 to 5,000 kg/hour for certain PET systems, and a water-recycling design intended to reduce resource consumption. For film recycling, it has described equipment capable of handling agricultural film with high sand content, using a pre-washing unit and water circulation to improve cleaning performance and reduce operating costs.
Its exhibition and product listings also emphasize modular system design for different feedstocks and end uses, including bottle-to-bottle, sheet, and chemical fiber applications.
Applications and End Markets
Grace Machinery’s equipment is used in several plastics-processing and recycling end markets:
- Water, drainage, and electrical pipe manufacturing
- PVC and PE pipe production
- Plastic profile extrusion
- PET bottle recycling and rPET preparation
- Film recycling, including agricultural film washing
- Granulation and material preparation for downstream processing
The company’s public materials suggest a particular emphasis on circular-economy applications, especially PET bottle-to-bottle recycling and water-saving wash systems. That positioning aligns with broader industry demand for equipment that supports recycled-content production, waste reduction, and lower water and energy intensity.
Global Presence and Market Position
Grace Machinery is an export-oriented Chinese machinery manufacturer headquartered in Zhangjiagang, a city known for plastics processing and machinery production clusters. Public listings describe it as serving customers in a wide range of countries, with references to 70-plus and 80-plus export markets in different sources.
The company is visible on international and industry trade platforms, including CHINAPLAS exhibitor listings and global business directories. Its public market position appears to be that of a specialized machinery supplier with strengths in extrusion and recycling lines rather than a diversified conglomerate.
Sustainability and Environmental Initiatives
Sustainability is a visible part of Grace Machinery’s product positioning, especially in recycling systems. The company states that its PET recycling lines incorporate water recycling to reduce freshwater consumption and support environmental protection. It also emphasizes equipment designed to convert waste plastics into reusable feedstocks for bottle-grade, fiber-grade, and sheet applications.
At the same time, the company’s sustainability profile is primarily product-led rather than reporting-led in the public sources available. The available materials do not provide a detailed corporate carbon inventory, emissions target, or verified life-cycle assessment data. The clearest evidence of environmental contribution is therefore through the enabling role of its machinery in plastics circularity.

Its economic impact is better understood through:
- Export manufacturing and foreign-market sales
- Local industrial employment in Zhangjiagang and Suzhou-area manufacturing clusters
- Support for downstream plastics conversion and recycling capacity, particularly in PET and pipe systems
Leadership and Corporate Governance
Public sources identify the company as a privately held enterprise founded in 2012. The reviewed materials do not provide a full board structure or detailed governance disclosures. Available listings show multiple named contacts, including sales and marketing personnel, which is typical of mid-sized export manufacturers operating through direct customer relationships and trade platforms.
