Leak Test
MCK Robotics and Equipment specializes in developing automated industrial leak testing devices. This equipment checks for leaks and checks for holes, pores, or cracks in parts.
Sealing is characterized by the ability to prevent the penetration of external elements into the interior of a part, circuit or housing, be they fluids, particles or air.
In this sense, if we want to prove that a product, material, container or hermetic seal has the appropriate configuration and sealing to prevent the passage of any fluid, we carry out the industrial tightness test.
The devices developed by MCK Robotics and Equipment are fully customized and with great attention to the peculiarities of each Client's products.
Leak testing is a procedure for verifying and measuring the tightness of components. It also serves to determine whether an object or system is operating within a specific leak limit.
A leak occurs when there's a defect—a hole, crack, or some other type of flaw—in an object, allowing the liquid or gas it contains to escape. Leak testing uses pressure to find these defects so they can be fixed as part of regular maintenance procedures.
We develop and manufacture leak testing systems to meet customer needs.
Leak tests using different technical concepts:
Pressure drop;
Differential pressure with reference standard body;
Immersion.
Several methods and/or test gases can be used:
Vacuum;
Nitrogen;
Helium;
Oxygen.
Detection methods in leak testing
Pressure drop: uses the change in pressure of an object or system under positive pressure to identify defects that cause leaks.
Pressure-vacuum: This method uses the pressurization of a test object and a reference volume. If a leak exists, the difference between the two will decrease.
Vacuum decay: This technique uses the pressure change of an object or system under negative pressure to identify leak faults.
Burst: Increases pressure to find the point at which the device will open, i.e. burst.
Chamber: Used to identify leak-causing defects in a sealed environment, such as a device or packaging.
Occlusion: identifies obstructions in the flow path of a gas to discover defects that cause leaks.
Products manufactured by MCK Handling can be purchased in up to 48 installments, using the BNDES card or through special financing conditions through FINAME .
