Engineered to handle extreme operating pressures up to 250 bar and thermal thresholds reaching 350°C in demanding Saudi polymer manufacturing plants.
Under the transformative framework of Saudi Vision 2030 and the National Industrial Development and Logistics Program (NIDLP), the Kingdom of Saudi Arabia is aggressively expanding its downstream petrochemical sector. Riyadh has evolved into a powerhouse for high-value polymer conversion, transforming raw resin production into complex extruded films, synthetic textiles, automotive polymers, and food-grade packaging.
The industrial zones across Riyadh—including MODON Riyadh Second and Third Industrial Cities—require continuous-operation polymer filtration systems capable of processing dense Polypropylene (PP), Polyethylene (LLDPE/HDPE), Polyethylene Terephthalate (PET), and Polyamide (Nylon) melt streams. In high-output polymer processing lines, minor particulate contaminants, gel specks, or degraded polymer gels lead to catastrophic line stoppages, spinneret degradation, and film tears.
As a premiere ODM Polymer Candle Filter Factory & Company serving the Riyadh market, Pujiang HG Plastic Machinery Co., Ltd. delivers custom-engineered metal matrix filter cartridges designed specifically to withstand harsh regional desert climates, extreme ambient processing temperatures, and continuous heavy-viscosity throughput.

Riyadh plastic processors often face extended lead times from Western OEMs. Our dedicated ODM manufacturing route guarantees expedited dispatch, customized CAD fitting, and buffer stock options for regional distributors in Saudi Arabia.
Whether your plant runs Maag, Nordson, Kreyenborg, BKG, or custom Asian extrusion platforms, our ODM engineering team manufactures candle filter cartridges matching exact thread, hexagonal nut, and flange specifications.
Every single polymer candle filter element undergoes rigorous bubble point testing (ISO 4003), flow permeability verification, and non-destructive ultrasonic seam weld inspection before export to Riyadh ports.
Discover how gradient porosity, metallurgy selection, and zero-dead-leg geometry optimize melt flow dynamics in high-viscosity applications.
We utilize prime grade certified metals tailored to chemical resistance and temperature thresholds:
Our candle elements feature a multi-tiered sintered structure designed to optimize dirt holding capacity while maintaining strict absolute rating boundaries:
In high-viscosity resin melt streams—such as those encountered in Riyadh's large-scale polypropylene pelletizing and BOPP film lines—stagnant melt flow regions ("dead legs") lead to thermal degradation. Stagnant polymer remains inside the filter housing under high temperature, breaking down into carbonized black spots and cross-linked gels that periodically shed into the clean filtrate.
Pujiang HG’s ODM engineering team utilizes Computational Fluid Dynamics (CFD) modeling to design custom internal support cores. Our internal core tubes feature variable-pitch perforations and smooth hydraulic transitions. This design ensures uniform fluid velocity across the entire length of the candle element, eliminating stagnant zones, minimizing total pressure drop ($\Delta P$), and preventing carbon spot contamination in high-purity Saudi packaging products.
Providing engineered continuous polymer filtration (CPF) media across key industrial sectors in Riyadh, Jubail, and Yanbu.
For flexible packaging manufacturers in Riyadh's Industrial Cities, line tears during biaxial stretching cause thousands of dollars in lost operational efficiency per hour. Our pleated SUS 316L sintered felt candle filters remove sub-micron gels and hard catalysts, guaranteeing high tensile strength and clear optical clarity for food packaging films.
Supplying the healthcare, hygiene, and geotextile industries under Saudi Vision 2030 initiatives require flawless melt spinning. Our ODM candle filter bundles feature ultra-fine micron ratings (5μm to 15μm) that protect delicate spinnerets from hole blockages and filament breakage during high-speed spinning.
As Saudi Arabia implements circular plastic initiatives, recyclers in Riyadh process contaminated post-industrial and post-consumer PE/PP scrap. Our heavy-duty wire mesh screens and robust candle filters handle high dirt loads, protecting downstream underwater pelletizers and screen changers.
Pujiang HG's commitment to advancing polymer melt filtration through nano-technology surface treatments and digital monitoring integration.
Traditional stainless steel filter surfaces tend to accumulate cross-linked polymer degradation products during long campaigns. Pujiang HG is deploying advanced SilcoTek chemical vapor deposition (CVD) coatings and nano-passivated ceramic thin films onto SUS 316L candle filters. This surface treatment reduces melt adhesion by 65%, facilitating faster TEG cleaning cycles and preventing carbon buildup during extrusion shutdowns.
Integrating smart pressure sensor telemetry with numerical filter-cake building algorithms allows Riyadh plant engineers to forecast exact filter element clogging curves based on melt temperature, shear rate, and resin batch viscosity variations. This eliminates unscheduled shutdowns and optimizes cleaning schedules for continuous polymer filtration (CPF) duplex systems.
Importing industrial components into Saudi Arabia requires full alignment with local regulatory bodies. Pujiang HG provides complete documentation packages required for smooth customs clearance through SABER / SALEEM platforms at King Abdulaziz Port (Dammam) and Riyadh Dry Port:
Pujiang HG understands that fast delivery timelines and reliable technical support are critical for plant managers in Saudi Arabia. Our international engineering desk provides direct CAD drawing reviews, reverse-engineering services for obsolete Western filter elements, and custom dimensional verification within 24 hours of inquiry.
We work alongside regional logistics networks to ensure rapid sea and air freight delivery directly to plant locations in Riyadh, Jubail Industrial City, Yanbu Commercial Port, and Dammam Industrial Estates.
