Explore our core Original Design Manufacturing (ODM) portfolio. Engineered with advanced metallurgical standards, high-torque extrusion drives, and precision micron melt filters for optimal pelletizing output.
The global thermoplastic recycling industry is undergoing a paradigm shift driven by stringent circular economy legislation, corporate ESG commitments, and aggressive net-zero carbon mandates. Regulatory frameworks such as the European Union’s Packaging and Packaging Waste Regulation (PPWR) and the United States FDA Letter of No Objection (LNO) requirements for food-contact recycled plastics (PCR) have redefined the baseline standards for plastic processing machinery. Standard off-the-shelf recycling systems are no longer sufficient to process highly contaminated, multi-layered post-consumer plastic waste stream without causing thermal degradation, melt quality fluctuations, or machine downtime.
As a premier ODM Plastic Recycling Machine Supplier & Factory, our facility specializes in Original Design Manufacturing that integrates advanced mechanical shear, multi-vent vacuum degassing, and high-efficiency polymer melt filtration (CPF candle filter systems and continuous leaf disc screen changers). By custom-engineering machinery according to specific resin melt flow index (MFI), contaminant levels, and target pellet viscosity, we empower global recyclers to turn industrial scrap and post-consumer polymers into high-purity recycled resins rivaling virgin plastic standards.
Building high-yield granulating equipment requires deep expertise in polymer rheology, heat dissipation, and abrasive wear mitigation. Our ODM manufacturing framework covers the full spectrum of recycling technology:
High-torque dual-shaft shredders combined with friction washers remove dirt, paper labels, glue residues, and heavy minerals. Stainless steel friction blades (SUS316/D2 steel) ensure chemical resistance during hot caustic wash cycles for PET bottle flakes or heavily soiled agricultural films.
Our extruders feature bimetallic barrels treated with tungsten carbide alloys (HIP process) to withstand abrasive glass fibers and inorganic fillers. Modular screw configurations allow custom shear profiles to prevent chain scission while maximizing output rates.
High-vacuum multi-vent degassing zones evacuate residual moisture, inks, volatile organic compounds (VOCs), and monomer gases. Dual atmospheric and sub-zero liquid ring vacuum pumps guarantee bubble-free granule creation with zero porosity.
China has established itself as the world’s most comprehensive manufacturing ecosystem for plastics machinery and polymer filtration hardware. Partnering directly with an experienced OEM/ODM factory in Zhejiang, China provides unmatched technical and commercial advantages:
Located in the heart of China’s industrial machinery cluster, our factory maintains direct access to specialized stainless steel foundries, precision CNC machining centers, vacuum sintering furnaces, and automated wire weaving facilities. This localized integration drastically reduces component lead times and cost overheads.
Unlike standard machinery resellers, our in-house R&D team provides CAD/SolidWorks 3D modeling, fluid dynamic simulation (CFD) for melt distribution, and customizable layout engineering. We adapt motor ratings, gearboxes (Flender/Guomao), screw L/D ratios, and control systems (Siemens PLC) to match exact regional voltage and factory footprints.
We adhere to strict ISO9001 quality management systems and CE safety directives. Every recycling line undergoes rigorous dry-running and load testing with real customer raw materials before shipment. Metallurgical analysis, ultrasonic weld testing, and pressure tolerance testing are recorded for every pressure vessel and filter housing.

The global recycling equipment market is evolving rapidly. Global procurement teams and plant managers must align their capital expenditure with five core technological vectors:
Rising demand for Food-Contact Grade recycled PET (rPET) and HDPE requires deep decontamination. Advanced extruders now integrate solid-state polycondensation (SSP) prep reactors and ultra-fine candle melt filters to remove contaminants at sub-micron levels.
To eliminate manual screen changes that cause line interruptions, automated backwashing screen changers and high-surface-area leaf disc filters are becoming industry standard, reducing scrap rates during screen changeovers by up to 90%.
Electricity costs represent up to 40% of operational expenses in pelletizing plants. Modern ODM lines incorporate ceramic infrared heaters, direct-drive motors, and barrel insulation covers to minimize thermal energy loss.
Integrated sensors monitor melt pressure drops (Delta-P), barrel temperature profiles, motor torque, and melt viscosity in real time. Cloud connectivity enables predictive maintenance and immediate remote technical support.
Different industrial plastics require unique processing conditions. Our ODM machinery is tailored specifically to solve process bottlenecks across key sector applications:
Challenge: High-speed film lines generate massive volumes of edge trims and printed waste. Film flakes have very low bulk density and trap significant surface air, leading to feeding bridging and melt surges.
ODM Solution: Integrated cutter-compactor recycling system. The rotating blades pre-heat, compact, and continuously feed film scrap directly into the extruder screw without pre-crushing. Stainless steel leaf disc filters (SUS316L) ensure pinhole-free film blown output upon re-use.
Challenge: Flakes contain paper fibers, metal particles, soil, and mixed polymer contaminants that quickly clog traditional woven wire mesh screens.
ODM Solution: Double-piston continuous hydraulic screen changer paired with multi-layer SUS304 pleated candle filter cartridges. The large surface area extends filter service life by 300% before needing ultrasonic solvent cleaning.
Challenge: Ultra-high intrinsic viscosity requirements; thermal degradation during melting causes fiber snapping during re-spinning.
ODM Solution: Low-shear, high-torque single-screw extruder equipped with a specialized CPF (Candle Power Filter) system. Micron ratings from 5μm to 20μm remove microscopic carbon gels, ensuring smooth filament extrusion.
When sourcing ODM plastic recycling machinery and polymer melt filtration components from China factories, procurement directors should evaluate vendors based on four key operational criteria:
Determine the exact melt flow index (MFI), moisture percentage, and melting point of your input scrap. High MFI polymers require precision pelletizers (water-ring or underwater pelletizing) to prevent strand wrapping and uneven granule size.
Select filter media based on target product quality. Sintered metal fiber felt offers high dirt-holding capacity and low pressure drop ($\Delta P$), ideal for fine filtration down to 5 microns. Woven wire mesh is suitable for coarse filtration (80–200 mesh).
Evaluate continuous operating costs rather than initial capital purchase price. Look for modular screw segments, replaceable bimetallic barrel liners, and easily reusable stainless filter elements that can be pyrolyzed or ultrasonically cleaned multiple times.

OEM (Original Equipment Manufacturer) involves manufacturing machines based strictly on existing designs and CAD blueprints supplied by the buyer. ODM (Original Design Manufacturer) means our factory provides end-to-end design engineering, R&D, structural customization, and metallurgical optimization based on your raw material input specifications and target granule application. ODM allows you to get a completely custom machine tailored to your exact production challenges without maintaining an internal engineering design team.
CPF Candle Filter Cartridges utilize multi-layer pleated stainless steel sintered fiber felt or wire mesh wrapped around a central perforated core. This construction increases the total filtration surface area by 500% to 1000% within the same housing volume compared to flat mesh discs. The increased surface area drastically reduces melt pressure drop ($\Delta P$), lowers shear stress on the polymer, extends continuous operation time between filter replacements, and enables ultra-fine filtration down to 5 microns.
Yes. For heavily contaminated post-consumer waste (such as municipal PE/PP film or agricultural film), our ODM recycling lines integrate a double-stage degassing extruder layout (mother-baby extruder configuration) paired with high-vacuum liquid-ring pumps (-0.098 MPa) and a continuous hydraulic backwashing screen changer. This system automatically ejects solid contaminants while evacuating moisture and residual paper volatiles without stopping production.
We utilize premium grade AISI 304, 304L, 316, and 316L stainless steel. For highly corrosive polymers or flame-retardant additive masterbatches, we also supply Hastelloy C-276 and Inconel filter alloys upon request. All materials undergo spectral metallurgical testing to verify corrosion resistance and mechanical integrity at operating temperatures up to 350°C and melt pressures up to 30 MPa.
Absolutely. Stainless steel melt filter elements are engineered for long-term reusability. Spent filter elements can be cleaned using thermal pyrolysis ovens (calcination to burn off polymer residue), TEG (Triethylene Glycol) chemical boiling, ultrasonic bath cleaning, and high-pressure fluid back-flushing. Proper cleaning protocols allow candle filters and leaf discs to be reused 10 to 20 times, significantly reducing consumables expenditure.
Standard replacement screen mesh filters and stock candle cartridges ship within 7–12 working days. Custom-engineered ODM candle filter assemblies or specialized leaf disc systems take approximately 20–25 days. Complete turn-key plastic granulating and pelletizing production lines have a typical manufacturing lead time of 45 to 60 days, inclusive of CAD engineering approval, CNC machining, assembly, and factory wet-testing.
