This week, we are sharing a case study on automatic sorting for felt materials.
A customer approached us with an issue where their felt products had thickness defects and requested full-scale sorting.
The product in question is a rectangular die-cut component that exceeded the upper limit of thickness tolerance, making it impossible to assemble with other parts. This caused significant production challenges for the customer.
Product Information for Sorting
- Size: Thickness 2.1mm (±0.2mm) × Width 15mm × Length 33mm
- Quantity: Approximately 45,000 pieces
Felt material presents a risk where thickness irregularities are difficult to detect at the raw material stage, increasing the likelihood of defective parts being mixed into production.
Using a dial gauge for manual measurement can cause slight compression, making it difficult for human inspectors to measure accurately and sort efficiently.
How Does Automatic Sorting Solve This Issue?
With our automatic sorting machine, we achieved:
✅ Cycle time: 1 second per piece
✅ Daily output: Over 20,000 pieces per shift
Challenges in Sorting Felt Material
Felt material easily tangles, requiring a parts feeder to separate each piece properly.
Additionally, the product tends to twist or deform, making it challenging to accurately measure the minimum thickness using image analysis.
However, we successfully sorted the parts with precision:
✅ Accepted parts: Thickness 2.2 – 2.6mm
❌ Rejected parts: Thickness 2.7 – 2.8mm
