Leak Testing Machines

A leak can be defined as an unintended crack, hole or porosity in an enveloping wall or joint, which must contain or exclude different fluids and gases allowing the escape of closed medium. Critical leak spots in closed systems are usually connections, gaskets, welded and brazed joints, defects in material, etc. A leak test procedure is usually a quality control step to assure device integrity, and should preferably be a one-time non-destructive test, without impact on the environment and operators. Several leak-testing techniques are available, spanning from very simple approaches to systems that are more complex.

Torr has developed itself as a master in Leak Testing technology. Torr has near about 1200 satisfied and delighted deliveries & installations of leak testing machines of different type. We have developed unique Leak Testing Machines which are highly in demand. Our Leak Test Machines which have the capability of challenging tiniest leakages with highest accuracy with pressure drop & void methods.

A dedicated machine known as a leak testing machine is utilized to discover and measure leaks in systems, components, or items to ensure they meet watertightness or airtightness specifications. These machines are essential in industries such as consumer electronics, automotive, aerospace, and medical equipment, where even small leaks could compromise performance, safety, or regulatory compliance.

Leak testing: What Is It?

An important quality control process known as leak testing detects unanticipated pathways through which gases or liquids can exit a closed system. Prior to placing products for sale, the process helps manufacturers detect defects such as cracks, poor seals, or improper assembly. Depending on the product design, material, and use, numerous methods exist to perform leak tests.

Typical Techniques for Leak Testing

• Pressure Decay Testing: Once air pressure has been applied to the component, the system monitors any loss of pressure over time. A loss indicates a potential leak.
• Mass Flow Testing: Measures the speed at which air flows through a component under constant pressure. A greater flow rate could be an indication of a leak.
• Vacuum Decay Testing: This test uses a vacuum and is similar to pressure decay. An increase in pressure following the removal of the component suggests a leak.
• Differential pressure testing refers to comparing a test part with a known, quality reference part. Changes in pressure readings may indicate leakage.
• Helium or Hydrogen Leak Testing: This technique requires trace gases, e.g., helium or hydrogen, to be introduced into the component. Leaks are detected by detectors when they find any gas going out.
• Bubble Testing: Air is introduced while the component is submerged in water. Bubbles indicate a leak.

Uses in Various Industries
Leak testing machines are required in most industries:

• Automotive: Inspecting radiators, air conditioning components, and fuel systems.
• Medical Devices: Maintaining the integrity of devices like IV bags, syringes, and catheters.
• Aerospace: Verifying whether fuel systems and aircraft cabins are air-tight.
• Consumer electronics: Ensuring that equipment is sealed to prevent dust or water entry

Attributes of Modern Leak Testing Equipment
Modern leak testing equipment often possesses the following attributes:
Automated Sealing Mechanisms: In order to ensure trusted and consistent testing.

• Sensitive Sensors: Capable of detecting trace gas levels or very small pressure changes.
• Data Logging and Analysis Tools: In order to assist in quality control and document test results.
• Operator-Friendly Interfaces: Touchscreens and software that allow operators to easily observe tests and define parameters.
• Integration Capabilities: The ability to integrate automated test procedures into the production lines.
