The Metropolitan Administration of Bangkok and surrounding industrial zones—including Samut Prakan, Pathum Thani, Samut Sakhon, and the Eastern Economic Corridor (EEC) hubs like Chonburi and Rayong—form the beating heart of Thailand’s plastic manufacturing and recycling economy. Under Thailand’s national Bio-Circular-Green (BCG) Economic Model and the Roadmap on Plastic Waste Management 2018–2030, the region is undergoing an unprecedented transformation towards 100% circular plastic recovery.
Thailand's stringent ban on single-use plastics and mandated recycled content in packaging (such as rPET for food and beverage bottles) has escalated the demand for food-grade, high-purity recycled resins. Factories supplying major FMCG brands in Bangkok must install advanced melt filtration systems capable of removing gels, carbonized specks, and particulate down to 20 microns.
High concentrations of blow molding, film blowing, and injection molding facilities in Amata City, Bangpoo, and Navanakorn generate thousands of tons of post-industrial regrind (PIR) daily. Local recycling factories require continuous pelletizing extruders that minimize thermal degradation while handling volatile polymer flow rates.
Bangkok's tropical climate yields high ambient humidity and damp post-consumer waste (PCW) feedstocks (PE films, PP bags, PET bottles). Machinery tailored for this region must feature extended L/D ratio extruders equipped with dual-zone high-vacuum degassing ports to prevent porosity, bubbles, and pinholes in the final re-granulated pellets.
Modern polymer recycling demands an integrated engineering approach. To process contaminated agricultural films, woven bags, and rigid electronic scraps effectively, a plant must synchronize crushing, friction washing, thermal drying, vacuum degassing extrusion, and microscopic melt purification into a continuous automation loop.
Our single-screw and twin-screw granulating systems engineered for Bangkok factories feature specialized L/D ratios ranging from 30:1 to 36:1. Incorporating bimetallic alloy barrels and double vacuum degassing zones (-0.095 MPa), the system efficiently extracts residual moisture, ink solvents, and low-molecular-weight volatiles prior to melt filtration.
Filtration is the ultimate gatekeeper of polymer quality. Utilizing SUS 304 and SUS 316L multi-layer sintered metal mesh, leaf disc filters, and candle filter cartridges (CPF), our machinery captures microscopic contaminants without inducing shear degradation or excessive pressure drops (ΔP) in high-viscosity melts like rHDPE, rPP, and rPET.
| System Type | Optimal Feedstock Type | Filtration Precision | Throughput Capacity | Bangkok Industrial Suitability |
|---|---|---|---|---|
| Water-Ring Strand Pelletizing | Rigid Regrind (HDPE, PP, ABS) | 80 - 150 Micron (Screen Mesh) | 300 - 1,200 kg/h | Ideal for Samut Prakan rigid drum & crate recyclers. |
| Underwater Pelletizing System | PET, Soft PVC, High-MFI PP | 20 - 50 Micron (Candle Filter / CPF) | 500 - 3,000 kg/h | Essential for food-contact packaging lines in EEC. |
| Air-Cooled Die-Face Cutting | Filled Masterbatch, LDPE Film | 100 - 200 Micron (Hydraulic Dual-Piston) | 150 - 600 kg/h | Cost-effective for smaller workshops in Pathum Thani. |
| Automatic Backflushing Continuous | Post-Consumer Agricultural Film | 40 - 80 Micron (Sintered Wire Mesh) | 400 - 2,000 kg/h | Uninterrupted 24/7 operation with minimal operator labor. |
Procurement executives and plant engineers in Bangkok face a critical choice between expensive European machinery, localized assembly resellers, and direct-from-factory sourcing from leading Chinese OEM specialists (such as Pujiang HG Plastic Machinery). Direct factory procurement delivers unparalleled economic and engineering advantages.
Direct China factory procurement offers a 45% to 60% CAPEX savings compared to Western European alternatives without compromising component quality (incorporating Siemens motors, Schneider electrics, RKC temperature controllers, and Japanese NSK bearings).
Unlike standardized off-the-shelf reseller units in Thailand, our engineering team custom-configures screw profiles, barrel vent placements, heater band specs, and filter micron ratings tailored strictly to your specific factory layout and scrap contamination profiles.
Leveraging the ASEAN-China Free Trade Area (ACFTA), machinery imports accompanied by Form E certificates enjoy zero-to-minimal import tariff rates in Thailand. Maritime transit from Ningbo/Shanghai to Laem Chabang Port takes just 5 to 7 days.
Engineered for real-world manufacturing conditions, our plastic pelletizing lines and polymer melt filters are deployed across diverse industrial scenarios throughout Thailand:
Challenge: Heavy paper label contamination, mineral fillers, and dirt sticking to crushed rigid flakes.
Solution: Heavy-duty wet crusher line paired with a double-stage pelletizing extruder. Integrated with continuous dual-piston hydraulic screen changers and SUS 304 filter mesh packs to extract sand and metallic debris without stopping production.
Challenge: High moisture retention, low bulk density, and thermal sensitive film material resulting in degraded melt index (MFI).
Solution: Integrated Cutter-Compactor Shredder-Pelletizing System. The friction heat pre-dries the film before forced feeding into the extruder, while vacuum degassing removes moisture, creating uniform, bubble-free pellets.
Challenge: Strict requirements for IV (Intrinsic Viscosity) retention and microscopic black speck filtration down to 25 microns for sheet extrusion and fiber spinning.
Solution: Polymer Candle Filter Assembly (CPF) featuring SUS 316L pleated wire mesh filter elements, ensuring long operational life and exceptionally low pressure drop.
