High-efficiency continuous candle filters, disc assemblies, and recycling lines engineered for intense polymer melt purification.
Addressing the structural shift toward circular economy compliance, material yield maximization, and energy-efficient polymer reprocessing.
Global nonwoven fabric manufacturers—producing Spunbond, Meltblown, Spunlace, and Airlaid materials—face strict zero-landfill mandates. Buying decision-makers require advanced recycling equipment capable of converting edge trim, roll off-cuts, and post-industrial waste directly into virgin-grade resin pellets without damaging molecular weight distribution.
Traditional recycling methods subject Polypropylene (PP) and Polyester (PET) nonwovens to excessive heat history, leading to drastic Melt Flow Index (MFI) spikes and chain scission. Technical buyers actively seek Original Design Manufacturers (ODM) providing dual-vented vacuum degassing extruders and gentle plasticizing mechanisms.
Nonwoven manufacturing demands immaculate polymer purity to avoid spinneret nozzle clogging during re-extrusion. B2B procurement specs demand integrate continuous melt filtration—such as Stainless Steel SUS304/316L Candle Filters and Leaf Disc Filters—capable of sub-20 micron rating retention.
An end-to-end technological breakdown of high-output pelletizing lines designed for low-density, high-surface-area synthetic fiber scrap.
Heavy-duty integrated cutter-compactors mechanically pre-shear and friction-heat nonwoven webs, converting fluffy scrap into dense agglomerates ready for smooth extruder feeding.
Specially designed L/D 34:1 to 38:1 single or twin screws plasticize polymer melt under precise temperature zones, featuring high-vacuum vents to purge moisture, spin finishes, and volatile organics.
Utilizing automatic dual-bolt hydraulic screen changers equipped with multi-layer SUS 304/316 Pleated Candle Filters or Leaf Discs, removing degraded gels and micro-particles.
Precision cutting blades slice molten polymer streams under temperature-controlled water. Dynamic centrifugal dewatering yields uniform, dust-free spherical pellets.
As a specialized ODM exporter, Pujiang HG Plastic Machinery Co., Ltd. integrates custom melt filtration units directly into nonwoven recycling machines. The inclusion of high-area Stainless Steel Melt Pleated Candle Filters or Leaf Disc Filters dramatically extends filtration lifespan, prevents backpressure surges, and eliminates production downtime. Compared to standard single-mesh screens, our candle filter assemblies expand effective filtration area by up to 500%, allowing recycled melt to seamlessly feed high-speed spunbond lines without causing filament breaks.

Tailoring engineering design, safety protocols, and thermal controls to regional manufacturing standards across North America, Europe, and Asia-Pacific.
European nonwoven converters are strictly governed by mandatory Recycled Content Directives. Procurement intent centers around zero-emission equipment with CE certification, ATEX-rated explosion-proof electricals, and energy recovery systems.
US buyers emphasize continuous duty cycles, high hourly tonnage output, and heavy-duty mechanical reliability. Machinery must satisfy NFPA/OSHA workplace safety standards and electrical components must meet UL/CSA certifications.
Rapidly expanding hygiene and medical nonwoven hubs require versatile recycling machines capable of handling varying MFI inputs (Spunbond PP scrap mixed with SMS or Meltblown off-cuts) while maintaining low operational expenditure.
Over two decades of precision manufacturing excellence in polymer melt filtration systems, leaf disc filters, screen mesh elements, and custom plastic recycling machinery.
Every recycling line is engineered to order. We customize screw geometry, barrel heating zones, filter micron ratings, and pelletizer configurations according to your exact polymer rheology.
Our polymer candle filters and screen mesh components are fabricated using top-tier SUS 304 / 316L stainless steel, undergo vacuum sintering, and pass ultrasonic bubble-point testing.
From initial lab sample testing of your nonwoven waste to machine commissioning, operational training, and long-term consumable replacement—we provide end-to-end global service.
Our low-energy pelletizing systems allow nonwoven producers to reintroduce up to 20-30% recycled pellet content into virgin spinning lines without compromising web tensile strength.
