Thickness measurement in glass: application of the Magna-Mike 8600

In the glass industry, the difference between a world-class container and a rejected batch is measured in microns. Whether in the mass production of tequila bottles in Jalisco or in architectural glass in the central part of the country, the uniformity of the walls determines mechanical strength and final safety.

Controlling thickness prevents line stoppages due to breakage and reduces raw material waste. AtZION NDT, we help migrate from slow destructive testing to real-time quality control throughNon-Destructive Testing (NDT).

How to measure glass thickness

non-destructively?

There are two leading technologies that we select based on the geometry of your piece:

1. Hall Effect (Magna-Mike 8600): Ideal for complex containers, bottles, and small parts. It uses a magnetic probe and a steel ball (target) to measure even in corners and bottoms where other sensors fail.

2. High-Frequency Ultrasound (39DL PLUSand45MG): The solution for flat glass, mirrors, or pipes where a ball cannot be introduced. It works by measuring the time of flight of an acoustic wave.

Hall Effect or ultrasound

for quality control?

• Hall Effect Principle: The equipment detects the strength of the magnetic field between the probe and the ball. As the thickness of the glass varies, the intensity changes proportionally, allowing for real-time recording of minimum values as the probe is slid.

• Ultrasonic Principle: The transducer emits a pulse that travels at ~5,600 m/s in glass. These characteristics allow for the detection of laminations, lack of adhesion, or the measurement of coatings in thermal glass.

Regulatory Framework and Quality Standards: The Language of Technical Certainty

In the glass sector, compliance with national and international regulations is the boundary between a local supplier and a global exporter. The use of NDT technologies in ZION NDT ensures that your production aligns with the most demanding standards:

International Regulations: ASTM and ISO

• ASTM C147:Establishes standard test methods for the internal pressure resistance of glass containers. The uniformity of thickness is the determining factor to avoid critical failures under pressure.

• ASTM E797:Standard practice for measuring thicknesses using the manual ultrasonic pulse-echo method. It is the regulatory basis for the use of equipment such as the 39DL PLUS and 45MG.

• ISO 8113:International standard that specifies the resistance to vertical load for glass containers. An inconsistent wall thickness compromises structural integrity during stacking.

• ISO 9001:Although it is a management standard, process control through digital measurement with data logging (Data Logger) is essential for the traceability and continuous improvement required by this certification.

National Regulations: NMX and NOM

• NMX-E-153-CNCP: Mexican standard that regulates glass containers for food and beverages. It defines the resistance and safety parameters that containers manufactured in the national territory must meet.

• NOM-002-SCFI: Related to net content and tolerances. Although it focuses on the product, the accuracy of the container's volume directly depends on the consistency of the glass wall thickness.
