5-Ton PET Broom Filament Fully Automatic Production Line Put into Operation
The complete turnkey project—including design, manufacturing, installation, commissioning, and trial production—is now fully operational and running with stable performance. The system is applied to a wide range of industrial and food-grade filtration products, such as dewatering mesh monofilaments, food-grade filter mesh, juice press filter mesh, and other filtration components.
1. Phase II Launch: Building a More Advanced PET Monofilament Production Line
Following the successful operation of the first PET monofilament production line, the client initiated the second-phase project: a 5-ton PET broom filament production line designed for expanding output and improving product quality. The excellent performance of the first line strengthened the client’s confidence in our equipment and engineering services.
The new line integrates the latest technology in PET filament extrusion systems, energy-saving control, and automated operation, ensuring the client can scale their PET broom filament machine and cleaning brush filament production line to meet future capacity planning and product upgrades.
2. Challenges: Recycled PET Processing & Production Stability
The raw material consists of recycled PET bottle flakes. Despite washing, the flakes still contain contaminants that affect PET recycling filament processing, such as:
Dust, lightweight label fibers, oil contamination
Occasional metal fragments
PET material’s tendency to oxidize or carbonize during heating
Micro-impurities leading to spinneret blockage, filament breakage, surface scratches, and diameter fluctuation
These issues reduced output, increased downtime, and pushed operational costs higher.
The client needed a PET monofilament plant turnkey solution specifically optimized for recycled PET to enhance process stability and final filament quality.
3. Customized Solution: Purification + Filtration + Stable Extrusion Structure
To meet the requirements of PET broom filament machine and PET brush filament production, Xinliaoyuan engineered an upgraded purification and filtration system tailored for recycled materials.
1) Raw Material Pretreatment & Purification
Hot-air circulation drying + cyclone dust removal to control dust and fiber residue
Oil-removal module for surface contamination
High-intensity magnetic iron-removal device to protect the screw and die head
2) Melt Filtration & Recycled PET Stability Control
3.5 m² dual-column melt filter for long filtration cycles and fewer interruptions
Optimized temperature control and screw structure designed specifically for recycled PET monofilament extrusion, reducing degradation and stabilizing melt flow
These configurations ensure smoother operation of the PET filament manufacturing equipment and improved process reliability.
4. Project Results: Improved Stability, Output, and Filament Performance
1) Product Quality Improvement
Smoother and more uniform filament surface suitable for broom filament production line and cleaning brush filament production line
Enhanced tensile strength and knot strength
Reduced filament breakage and fewer spinneret blockages
2) Output & Efficiency
Stable daily output of approximately 5 tons
Reduced downtime and better raw-material utilization
Higher automation lowers labor cost and operator workload
3) Service Delivery
Factory test-run with material before shipment
On-site installation, commissioning, and operator training ensured smooth trial production
5. Client Feedback
“The production line operates reliably, and the entire process is now more controllable. Both broom and brush filaments meet our quality expectations. With the Phase II project, our production capability became more complete.”
