Precision Measurement of Black Milk Tea Lids with Sinowon Optical Imaging System

In precision manufacturing, accurate geometric dimension measurement directly impacts product quality and production efficiency. Sinowon, a leading Chinese manufacturer of optical measurement equipment, delivers exceptional performance in complex workpiece inspection. This case study demonstrates how our high-precision imaging measurement system overcomes challenges in measuring black milk tea lids.

1. Technical Challenges in Milk Tea Lid Measurement

As critical food packaging components, milk tea lids require precise dimensional control for proper sealing and user experience. Traditional methods face three key issues:

• Material Properties: Black surfaces absorb light, making edge detection difficult
• Curved Geometry: 3D measurement capability required for arched designs
• Production Demands: Need for fast, non-contact batch inspection

Sinowon's imaging measurement systems address these pain points through innovative optics and AI algorithms.

2. Sinowon's Advanced Measurement Solutions

A. Multi-Light Source Imaging System
Our patented coaxial LED ring flash and collimated light system adaptively adjust intensity/angle to capture high-contrast images of black surfaces (0.01mm edge resolution).

B. Measurement Software
Proprietary algorithms enable:

• Lid diameter (±2μm repeatability)
• Thread pitch (auto-recognition)
• Seal groove depth (3D profiling)
• Eccentricity/circularity (full perimeter analysis)

C. Smart Batch Inspection

• Auto-positioning: No fixtures needed
• One-touch measurement: 15 seconds/part
• Data traceability: Automated SPC reporting

3. Case Study: PP Black Milk Tea Lid

Using Sinowon Vision Measuring Machine vs. traditional calipers:

• 8x faster measurement speed
• Zero contact deformation
• Full-dimension inspection (diameter, threads, flatness)

4. Industry Applications

Our technology extends to:
✔ Food packaging (bottle caps, cans, tableware)
✔ Electronics (black connectors, shields)
✔ Precision hardware (bearings, gears)

ISO 9001 certified for quality assurance.
