In the plastic pellet production process, color purity often directly determines the product's selling price and market competitiveness. Especially for transparent, white, or light-colored plastic pellets, even tiny black specks can affect the appearance and quality of the final product.
The high-end pellet manufacturing industry has long faced systemic challenges in reducing losses and improving quality, particularly in meeting high purity requirements and controlling minor defects.
During the plastic pelletizing process, unstable temperature and pressure control can easily lead to carbonization, forming black specks (carbon deposits). Common impurities in these plastic pellets can range from burnt-yellow, irregularly shaped, large black specks to tiny specks (as small as 0.1mm) barely noticeable to the naked eye.
Previously, most plastic sorting equipment on the market could only identify and remove black specks larger than 0.35mm, failing to address smaller defects. This presented a headache for many demanding customers.
WESORT integrates high-precision optical inspection and intelligent purification technologies to develop a quality assurance solution covering all pellet categories.
The high-definition plastic pellet color sorter, equipped with micro-difference recognition technology, efficiently identifies and removes quality defects such as subtle color differences and tiny black spots (≥0.1mm) in virgin, recycled, and modified pellets.
By combining micro-difference imaging with AI deep learning algorithms, it can accurately identify and present millimeter-level quality defects in defective particles. Its one-click operation and automated process make it suitable for static laboratory environments and can be seamlessly integrated into production line systems for real-time monitoring and quality control.
Four-channel high-definition plastic pellet color sorter

As a professional plastic sorting equipment manufacturer, WESORT's crawler-type plastic color sorter has achieved a quantum leap in black spot detection accuracy and sorting efficiency:
1. High-precision detection: It can detect not only common large black spots but also tiny black spots smaller than 0.35mm, meeting the stringent requirements of high-end plastic pellet processing plants.
2. Multi-defect recognition: Simultaneously removes defects such as burnt brown particles, irregularly shaped particles, large black spots, and small black spots (0.1mm) to ensure the purity of finished pellets.
3. Belt-type design: More stable conveying, reducing vibration and missed selections, ensuring accuracy and stability of the sorting process.
4. High-efficiency production capacity: Maintains high sorting accuracy and consistency while processing large quantities of plastic pellets.
