1. Project Overview
-
Location: Malaysia
-
Date: August 22, 2025
-
Capacity: 2000kg/h (2 Tons per Batch)
-
Material: Imported & Local HDPE Rigid Plastics
-
Application: Premium Flakes for Injection Molding & Industrial Piping
2. The Challenge
The client, a licensed SME recycler in Malaysia, faced a dual challenge:
-
Strict Compliance: Malaysia’s environmental policies require imported plastic waste to be processed with high efficiency and zero pollution leakage.
-
Complex Feedstock: The mixed raw materials (local and imported) contained metal contaminants and non-plastic debris, requiring high-precision sorting to meet the quality standards of downstream pipe manufacturers.
-
Consistency: They needed to balance high cleanliness with a stable 2-ton-per-hour throughput to maintain their manufacturing license quotas.
3. Ruili Machinery’s Solution
We designed a comprehensive, multi-stage cleaning and sorting plant focused on purity and automated separation:
-
Advanced Pre-treatment: Integrated a Magnetic Separator and Eddy Current Separator to automatically remove ferrous and non-ferrous metals, ensuring the safety of downstream blades and the purity of the final flakes.
-
Professional Cleansing: Utilized a Constant Temperature Hot Alkaline Solution Tank combined with high-speed friction cleaners to strip away stubborn labels, industrial oils, and glue.
-
Density Separation: A precision flotation/sinking tank was used to isolate clean HDPE from other floating or sinking contaminants.
-
Efficient Drying: A combination of a High-Speed Centrifugal Dewatering Machine and a specialized hot air dryer ensured the flakes reached the optimal moisture level for immediate granulation.
4. Results & Performance
The 2000kg/h line has delivered exceptional results for the Malaysian facility:
-
High Purity Output: Produced clean PE/PP fragments with zero oil residue and minimal impurities, fully meeting the requirements of local injection molding plants.
-
Regulatory Approval: The plant’s efficiency and environmental safety features helped the client maintain full compliance with Malaysian recycling regulations.
-
Operational Stability: Successfully handles the 2-ton-per-hour batch processing requirements with lower labor intensity due to the automated sorting stages.
-
Downstream Value: The flakes are now sold at a premium to building pipe manufacturers, significantly increasing the client’s ROI.
5. Customer Feedback
“Ruili Machinery provided more than just equipment; they provided a compliant solution. The addition of the eddy current separator was a game-changer for our imported materials. We now produce some of the cleanest HDPE flakes in the region, and our downstream partners in the piping industry are extremely satisfied with the consistency.”
