Introduction
Deten (Nanjing) Machinery Co., Ltd. (Chinese: 南京德腾机械有限公司), also known as De Teng (Nanjing) Machinery Co., Ltd., is a Nanjing, Jiangsu-based Chinese manufacturer of plastics-processing machinery. Established in 2011, the company develops and supplies single-screw and twin-screw extrusion equipment, compounding systems, pelletizing lines, screw elements, screw barrels, and related extrusion solutions.
Deten operates within the machinery segment of the plastics industry, serving processors and compounders that convert polymers into modified materials, pellets, profiles, and other intermediate products. Its stated technical orientation combines Chinese manufacturing capabilities with management and engineering experience associated with German plastics-machinery practice.
The company’s activities reflect several important trends in plastics manufacturing: increasing demand for polymer compounding, greater use of recycled and performance-modified materials, the expansion of plastics applications in new-energy systems, and the need for integrated equipment rather than isolated machines. Deten’s product portfolio is centered on co-rotating and counter-rotating twin-screw extruders, two-stage compounding and pelletizing systems, and single-screw extrusion lines.
History and Development
Deten was founded in 2011 by a group of plastics-machinery professionals associated with China and Germany. The company was formed with an emphasis on extrusion engineering, production management, and practical experience in polymer compounding.
Several developments characterize its subsequent growth:
- 2011: Establishment. Deten began operations as a manufacturer and solution provider for single- and twin-screw extrusion lines.
- Expansion into integrated systems. The company broadened its portfolio from individual extruders to compounding, pelletizing, and two-stage extrusion systems intended for complete production lines.
- Diversification of applications. In addition to conventional polymer modification, Deten identified new-energy and food-processing applications as areas for wider extrusion use.
- Industry-exhibition participation. The company has promoted its machinery through plastics-industry exhibitions, including ChinaPlas-related activities and other Chinese plastics and sustainability events.
These developments place Deten within the broader expansion of China’s plastics-machinery sector, in which domestic manufacturers increasingly provide equipment for material development, recycling, compounding, and specialized processing.
Business Operations
Deten’s business model combines machinery manufacturing with engineering and process-support services. Its activities include:
- Research and development of extrusion equipment
- Mechanical and process design
- Manufacture of extruders and extrusion components
- Construction of compounding and pelletizing lines
- Sales and export support

The company describes itself as both a machine manufacturer and an extrusion-solution provider. This distinction is significant because compounding systems normally require coordination among feeding, conveying, melting, mixing, devolatilization, filtration, pelletizing, cooling, and control functions.
Available company profiles identify Nanjing, Jiangsu, as its operating base, with an address in the Jiangning District of Nanjing. The location provides access to the manufacturing, engineering, transport, and industrial networks of eastern China.
Products and Technologies
Twin-screw extruders
Twin-screw extruders form the core of Deten’s product range. They are commonly used for polymer blending, filler incorporation, reinforcement, reactive processing, masterbatch production, and recycling-related compounding.
The company identifies both co-rotating and counter-rotating twin-screw configurations in its product and service descriptions. Co-rotating machines are widely used for distributive and dispersive mixing, while counter-rotating designs can be selected for particular conveying, blending, or processing requirements.
Listed model examples include the MTS20 and MTS35 twin-screw extruders. In practical operation, equipment of this type typically integrates:
- Multiple gravimetric or volumetric feeders
- Modular screw elements
- Segmented barrel sections
- Heating and cooling zones
- Vacuum or atmospheric venting
- Pressure and melt-temperature monitoring
- Strand, water-ring, or other pelletizing arrangements
The use of modular screw elements allows processors to adjust conveying, kneading, mixing, residence time, and shear conditions to suit different polymer formulations.
Compounding and pelletizing lines
Deten supplies compounding extruders and pelletizing extruders for the production of uniform polymer pellets. A complete line may include raw-material feeding, premixing, extrusion, melt filtration, cooling, pelletizing, screening, and packaging.
The company’s portfolio includes two-stage compounding and pelletizing lines, which separate intensive melting and mixing from downstream homogenization or pellet formation. Two-stage arrangements can be useful where formulation stability, temperature control, throughput, or pellet quality requires separate process zones.
Single-screw extrusion equipment
Single-screw extruders are used in applications requiring stable melting, conveying, and shaping of thermoplastics. They can support profile, sheet, pipe, film, coating, and other extrusion processes, depending on the downstream die and calibration equipment.
Deten identifies single-screw extrusion lines among its areas of manufacture and solution provision.
Screw elements, barrels, and cylinders
The company also supplies key wear and process components, including:
- Screw elements
- Screw shafts and assembled screw sections
- Screw barrels
- Screw cylinders
- Related extrusion components
These parts influence mixing performance, throughput, pressure development, wear resistance, and maintenance intervals. Component selection is particularly important when processing glass-fiber-filled, mineral-filled, flame-retardant, recycled, or otherwise abrasive formulations.
Applications and End Markets
Deten’s machinery is associated primarily with polymer modification and materials compounding. Typical application areas include:
- Engineering-plastics compounding

The company has stated that its activities extend beyond traditional polymer modification into new-energy and food-processing fields. In new-energy manufacturing, extrusion and compounding equipment may be used for specialized polymer compounds, encapsulation-related materials, battery-component materials, and other formulations requiring controlled dispersion and thermal processing.
Food-processing extrusion differs from conventional plastics compounding in raw materials, hygiene expectations, process control, and equipment design. The inclusion of this field indicates an effort to apply extrusion expertise across multiple material-processing industries rather than limiting the business to plastics alone.
Global Presence and Market Position
Deten is headquartered in Nanjing and serves the domestic Chinese market while also pursuing overseas sales. Supplier profiles identify Shanghai as a loading port, reflecting the company’s access to China’s export logistics infrastructure.
Its international position is based primarily on specialized machinery supply rather than the large-scale production of commodity polymers. The company competes in a market that includes established European machinery producers, major Japanese suppliers, and a growing number of Chinese extrusion-equipment manufacturers.
Deten’s stated competitive proposition centers on:
- Integrated extrusion-line engineering
- Cost-performance considerations

Sustainability and Environmental Considerations
Deten’s machinery is connected to sustainability initiatives in plastics manufacturing through applications such as polymer recycling, material reuse, lightweighting, and the production of longer-life engineering compounds. Extrusion-based compounding can incorporate recycled polymers, mineral fillers, fibers, and additives into materials intended to replace virgin resin or reduce material consumption.
Potential sustainability contributions include:
- Processing of post-industrial and post-consumer recycled polymers
- Production of compounds with recycled-content formulations
- Material lightweighting through fillers and reinforcement
- Improved formulation consistency and reduced production scrap
- Integration of filtration and pelletizing systems for recycled feedstocks
The environmental performance of an extrusion line depends on more than the machine itself. Feedstock quality, electricity consumption, heating efficiency, cleaning requirements, filtration losses, pelletizing method, and the final product’s service life all affect overall impact. Recycling processes can also require additional thermal energy and may involve degradation or contamination challenges.
Industry requirements concerning recycled content, product traceability, emissions, and circularity are likely to influence the design of future compounding equipment. Machinery suppliers must therefore balance throughput and process stability with energy efficiency, material recovery, and reliable quality control.
