Rigid Plastic Washing Line for PP, HDPE, PVC
Turn crates, caps, pipes, and housings into clean, dry regrind. Our rigid‑wash system removes labels, oils, and fines, then dries to sub‑3% moisture for trouble‑free pelletizing.
- Sub‑3% residual moisture
- Removes labels, oils, adhesives
- Configurable throughput and layout
Key Benefits
Quick highlights that power modern, reliable recycling operations.
Lower Moisture, Higher Yield
Consistently reach sub-3% moisture for efficient pelletizing and stable throughput.
Superior Decontamination
Removes oils, labels, glue, and fines for cleaner flakes and fewer rejects.
Broad Material Compatibility
Handles LDPE/LLDPE films, BOPP, non-woven PP, rigid items, and more.
Efficient Utilities
Optimized washing loop cuts water and energy usage to lower operating costs.
Robust, Low-Maintenance Design
Industrial components built for uptime with simplified service and spare parts.
Scalable & Customizable
Configurable layout and capacities to match your floor plan and growth.
Regrind Materials Showcase
Common regrind categories we process and reuse across applications.

PP regrind
It’s common to see them as plastic chairs, toy parts, baskets, trash cans, pipes, bottles, bottle caps, and others because they provide stronger protection for goods.

HDPE regrind
HDPE regrind is widely used in containers, plastic bottles, pipes, playground equipment, and more due to its high strength, impact resistance, and chemical durability.

PVC regrind
PVC regrind is widely used in pipes, flooring, cable insulation, and window frames due to its durability, chemical resistance, and adaptability for various applications.

ABS regrind
ABS regrind is commonly used in automotive parts, electronics housings, toys, and appliances, valued for its toughness, impact resistance, and excellent surface finish.

Rigid Plastic
Producers are exploring solutions for PE pipes, PP containers, ABS automobile components, and more, with diverse origins across industries.

PET regrind
PET regrind is extensively used in bottles, food containers, and packaging due to strength, clarity, and excellent barrier properties for freshness.
Our Process
Six tightly integrated stages remove contamination, reduce moisture, and prepare plastics for reuse.
Pre‑Washing & Sorting
Remove large contaminants and prep materials for downstream steps.
Granulation
Uniform size reduction enables more effective cleaning and handling.
Intensive Washing
Friction cleaning lifts labels, dirt, and adhesive residues.
Separation
Sink‑float separates contaminants and isolates target materials.
Rinsing & Dewatering
Final rinsing and mechanical dewatering cut moisture significantly.
Thermal Drying
Controlled hot‑air drying achieves low residual moisture.
