With a view to providing our customers with solutions that guarantee the highest quality of production and the safety of their customers (the pressure in the finished can is from 6 to 10 bar!), We offer safe and proven aerosol leak testing systems. We carry out tests using three machines: automatic test bath, leakage sensor and laboratory test bath.
Automatic test bath
The use of continuously operating test tubs is one of the most popular methods of checking the tightness of aerosol containers with specific dimensions and valve types. The device consists of a bathtub unit, a drive unit, a dryer and a control cabinet and does not require an additional operator.
Let's take a look at the operation diagram of the test bath. Aerosol cans filled with the product are immersed in water at 60 ° C for a period of 3 to 5 minutes while slowly passing through the bathtub. If any of the cans is leaky - it should explode at this point. Leaking containers are removed from the production line. Watch the video: https://vimeo.com/222635544.
After leaving the tub, the containers are dried with a stream of air under high pressure. On offer Solmatic there are currently three automatic bathtubs adapted to production lines with different capacities. Each device is capable of testing 60, 80 or 120 cans per minute for tightness. Such a system, although proven and effective, is quite energy-intensive. It requires bringing to a high temperature and constantly maintaining about 1000-1500 liters of water in it.
Gas presence sensor
Aerosol manufacturers are constantly looking for new and better ways to test aerosol leaks. IN Solmatic we have created an innovative device at the individual request of one of our clients in Poland - a can tightness sensor (gateway for gas presence sensors). The device is used to control gas leakage from aerosol cans on the existing technological line and to eliminate gas leaking cans from further production. The gas sensor gate cooperates with a conveyor on which the aerosol cans checked by the gate move. Our device is equipped with eight very sensitive sensors that study the gas spectrum. How does the sensor work scheme look like in practice? Aerosol cans filled with gas are transported through two test stands. If the sensor detects gas, the can is leaking. A defective copy is blown off the conveyor by a compressed air nozzle and falls into a container located at the bottom of the device, from where it is picked up by the operator. The leak sensor is the first device of this type created in Solmatic. Our goal is to constantly improve this technology so that in the future it becomes a cheaper and energy-saving alternative to traditional methods of testing the tightness of aerosol containers.
Laboratory test bath
The laboratory test bath (manual) is the equivalent of the automatic test bath, which carries out tests on a smaller scale. The device is operated by a single operator.
How does a laboratory bathtub work? The device holds eight spray canisters filled with product. The operator, with the help of a lever, immerses the tested containers in heated water, which enables visual detection of leaks in the tested containers and elimination of defective items from the production line.
Which solution to choose?
It all depends on the preferences, needs and capabilities of the client. IN Solmatic we offer individual solutions that take into account the current requirements of our clients, guaranteeing a comprehensive order process and consulting at every stage of the project.
