Testing Background

Biopharmaceutical, vaccine, and chemical pharmaceutical injection manufacturers have extremely stringent control requirements for key dimensions—such as the bottle neck and body—when producing light-protective medical glass vials. The test specimens in this study are light-protective medical glass vials with a diameter of approximately 23.904 mm, made from Type I borosilicate glass and Type II low-borosilicate glass. Each vial must undergo precision comparison against customer drawings to ensure that every single vial meets the standards for injection packaging materials.

Two Major Challenges in Traditional Testing

1. Low efficiency. Traditional coordinate measuring machines require glass bottles to be placed horizontally in specialized fixtures. The inspection process is cumbersome, and the horizontal orientation prevents full coverage of the bottle’s surface, resulting in blind spots in the measurement results.

2. High changeover costs. Production lines handle a wide variety of glass bottles, and switching between different product specifications requires frequent program changes, leading to lengthy downtime for parameter adjustments and significantly slowing down the production line’s cycle time.

Solution: Telecentric Measurement System

To address these challenges, an online image measurement system has been introduced to enable a “place upright, measure immediately” inspection mode.

Key Features of the Equipment

1. The system offers multiple field-of-view settings ranging from 6 mm to 120 mm, meeting measurement needs for various parts of the bottle, from the neck to the body;

2. The professional optical design seamlessly combines high resolution with high magnification;

3. The compact design facilitates integration into existing production lines; a parallel light source, paired with a high-magnification lens and a high-frame-rate camera, clearly captures the product’s contours;

4. Equipped with OPMS measurement software, which features intuitive operation and enables precise measurement of glass bottle dimensions such as width, length, and height;

5. Compatible with both in-line inspection and offline spot-checking modes, making it suitable for a wide range of applications.

Test Methods

Place the glass products upright on the equipment platform, edit the corresponding measurement program, and click “Acquire.” The system will then automatically complete the inspection and display the dimensional results in an intuitive manner. There is no need to change fixtures or perform any additional operations for the same product; simply replace the product on the platform to quickly proceed to the next round of inspection.

Application Advantages

1. The measurement system offers high accuracy, excellent stability, and good repeatability, with outstanding long-term consistency;

2. The equipment is highly resistant to interference and adapts well to various environments, ensuring reliable output even under complex operating conditions;

3. The measurement process is highly automated and easy to operate, effectively reducing human error and significantly improving testing efficiency;

4. Data is real-time, accurate, and traceable, fully meeting quality control and traceability requirements;

5. We provide comprehensive hardware and software solutions with guaranteed quality, safety, and reliability.
