Introduction
Huizhou Tianhong Machinery Manufacturing Co., Ltd. (惠州市天宏机械制造有限公司) is a China-based plastics machinery manufacturer in Huizhou, Guangdong Province, specializing in high-precision plastic melt filtration equipment for recycling, pelletizing, and extrusion applications. The company’s core product family is its TL and TX series of screenless or automatic melt filters, which are positioned around continuous operation, high filtration precision, and reduced consumables use in plastics reprocessing lines.
Founded in 2021, Tianhong has built its market identity around melt filtration systems used in recycled pellet production, pipe extrusion, and sheet extrusion, with reported sales activity in domestic and export markets. The company states that its TX series carries CE and ISO certifications and is supported by proprietary patents, while exhibition and product materials describe its focus on uninterrupted filtration, maintenance intervals beyond 30 days, and filtration precision down to 250 mesh (60 μm). In industry terms, Tianhong operates in a niche segment of the plastics machinery sector that links polymer recycling, extrusion quality control, and production efficiency.
History and Development
Tianhong’s public company materials indicate that it was established in 2021 and is headquartered in Huizhou, a manufacturing hub in Guangdong’s industrial belt. From its launch, the company concentrated on plastic melt automatic filters rather than general-purpose plastics machinery, giving it a specialized position in a technically demanding segment of extrusion filtration.
A second development milestone is the company’s reported creation of the TX series screenless melt filters, which it describes as a proprietary design protected by multiple patents and supported by CE and ISO certification. These systems are presented as an engineering response to two chronic issues in recycling and extrusion: pressure stability and downtime caused by screen changes.
A third milestone is Tianhong’s expansion into international trade and industry exhibitions. Company news states that by 2025–2026 it had been active at CHINAPLAS and reported export business in countries including Turkey, Indonesia, Argentina, the United Kingdom, Uzbekistan, Jordan, and Japan. That pattern suggests an effort to position the company not only as a domestic supplier but also as a cross-border provider of niche filtration systems.
Business Operations and Segments
Tianhong’s business is centered on equipment for the plastics recycling and extrusion filtration chain. Its product pages and company profile identify several main lines:
- Plastic melt automatic filters
- Plastic melt filter scrapers
- Plastic melt filter screen plates
- Plastic recycling filter control cabinets
- Electric oil pump hydraulic stations
The company describes its operations as combining customized R&D, manufacturing, and after-sales technical support. It also states that its team includes engineers and commissioning technicians familiar with plastic recycling production equipment and process requirements, which is consistent with the integration needed for melt filtration systems in extrusion lines.
Public profile data on its own website describes Tianhong as a relatively small enterprise, with 51–100 employees and annual sales in the range of US$10 million to US$50 million. A Chinaplas exhibitor listing identifies the company as a “Shining Niche” company, reinforcing its specialization within a narrower industrial segment rather than a broad-machinery portfolio.
Products and Technologies
Tianhong’s principal technology is screenless melt filtration, a class of equipment used to remove contaminants from molten plastic during recycling and extrusion. Its TX series is described as using a patented structural design that enables continuous operation, meaning the filter can keep running without the production interruptions associated with conventional screen replacement.
Key technical characteristics cited in the company’s materials include:
- Filtration precision up to 250 mesh (60 μm) for the TX series.
- A maintenance cycle exceeding 30 days, which the company says lowers labor and consumable costs.
- A TL650F model with a filtration area of 600 mm × 500 mm × 4 and a maximum filtration capacity of 4,000 kg/h.
- A TX650 model described as using 26 spiral-arranged blades and filtration micropores in the 40–120 mesh range, with a maximum output of 1,000 kg/h in one product listing.
- Product applications in PE, PP, ABS, EPS, XPS, PS, PET, and PVC recycling and in pipe and sheet extrusion lines.
The company also states that it uses laser drilling machines, a vacuum heat treatment workshop, and testing equipment in production, indicating an in-house manufacturing and quality-control capability relevant to precision filtration components. In process terms, this suggests an emphasis on durable filtration plates, wear resistance, and controlled pore geometry, all of which are important for stable melt flow and consistent pellet or sheet quality.
Applications and End Markets
Tianhong’s products are primarily used in plastic recycling granulation, pipe production, and sheet extrusion. The company explicitly links its filtration equipment to thermoplastics such as PE, PP, ABS, EPS, XPS, PS, PET, and PVC, which covers a broad set of commodity and engineering polymer reprocessing streams.
Its product descriptions also connect the equipment to downstream sectors producing:
- Recycled pellets
- Plastic pipes
- Plastic sheets
- Aluminum-plastic plate structures
- Other thermoplastic extrusion products
This customer base places Tianhong within the recycling-enabling layer of the plastics industry, where filtration quality directly affects melt cleanliness, die stability, and finished-product consistency. The company’s emphasis on uninterrupted filtration is especially relevant for facilities seeking to improve yield and reduce the downtime associated with manual screen changes.
Global Presence and Market Position
Tianhong presents itself as an exporter with global sales and international customer trust. Company news states that export business in 2025 reached markets including Turkey, Indonesia, Argentina, the United Kingdom, Uzbekistan, Jordan, and Japan. Its contact materials also identify a Turkish market exclusive authorized representative, which indicates a targeted sales structure in at least one foreign market.
In the market context, Tianhong occupies a niche position in the plastics machinery sector rather than a broad line of extrusion or injection molding equipment. Its specialization in melt filtration places it at an interface between recycling technology, extrusion process optimization, and plant efficiency. For processors and recyclers, this type of supplier competes on filtration precision, operational continuity, maintenance burden, and integration with extrusion lines rather than on machine breadth alone.
Research and Development
Tianhong consistently emphasizes in-house development and proprietary design in its product descriptions. The company states that its TX series is supported by core patents and that it holds independent intellectual property rights over its melt filtration systems.
Its development focus appears to include:
- Patented structural design for continuous filtration.
- Precision micro-pore drilling using laser equipment.
- Heat treatment and inspection processes for component durability and performance consistency.
- Customer-specific R&D and technical support across the equipment life cycle.
This R&D profile suggests a manufacturing model based on incremental mechanical innovation, process robustness, and adaptation to recycling-line operating conditions rather than on large-scale polymer chemistry or resin development.
Sustainability and Environmental Initiatives
Tianhong frames its equipment around energy saving, consumption reduction, and continuous production, which it presents as a route to lower carbon emissions in plastics processing. From a process standpoint, the company’s argument is that longer running times, fewer screen changes, and lower consumable use can reduce waste and improve operating efficiency in recycling and extrusion plants.
The sustainability case is therefore indirect but material: melt filtration systems can support the use of recovered plastics by making contaminated feedstocks more processable and by improving the economics of recycling operations. At the same time, these claims are best understood as equipment-level efficiency benefits rather than as evidence of broader lifecycle emissions reductions across the plastics value chain.
Quality Management and Certifications
Tianhong states that its TX series has obtained CE certification and ISO system certification. These references are relevant to international market access, especially for industrial equipment sold into multiple jurisdictions where conformity, documentation, and manufacturing consistency are central procurement criteria.
The company also stresses its use of testing equipment, vacuum heat treatment, and structured production capabilities as part of quality assurance. In technical equipment markets, such manufacturing controls are significant because filtration performance depends on both dimensional accuracy and long-term wear resistance.
Innovations and Future Outlook
Tianhong’s near-term development path appears to be centered on three themes: higher filtration precision, lower downtime, and broader export penetration. The company’s exhibition activity at CHINAPLAS and its ongoing product updates suggest that it is seeking visibility among processors and recyclers looking for more efficient melt-cleaning technologies.
Its future competitiveness will likely depend on whether it can continue to refine filter durability, maintain production consistency across heavier-duty applications, and adapt its filtration systems to evolving recycling streams and extrusion requirements. In the plastics machinery segment, these factors matter because recyclate quality, line uptime, and operating cost remain central purchasing criteria for processors evaluating specialized filtration equipment.
