Usually, the bottle cap is made of plastic through the injection molding process, coupled with today’s environmental protection, with the quality of recycled materials varying, these factors inevitably cause a variety of defects, common such as appearance defects: deformation, burrs, surface roughness, etc., such as size defects: diameter deviation, height inconsistency, wall thickness is not uniform, such as material defects: bubbles, cracks, color difference, pollution.
Below is a case study from Intsoft Tech on bottle cap machie vision defect detection.
Detection content
| No. | Defect type | Method | Detectable or not |
| 1 | Black spot | Positive light detection | YES |
| 2 | Gap | Positive light detection | YES |
| 3 | Scratch | Positive light detection | YES |
| 4 | With or without thread | Bevel detection | YES |
| 5 | Anti-theft ring | NO |
Note: All images of detected items should be clearly visible for detection by Intsoft Tech’s equipment.
Detection efficiency: More than 120 pieces per minute (depending on the feeding speed of the product)
