Aerosol leak testing is an extremely important part of the production process. When dealing with flammable gases, aerosol manufacturers cannot afford to use untested technologies. In order to provide our customers with solutions that guarantee the highest production quality and safety for their customers (the finished can is pressurised to between 6 and 10 bar!), we offer safe and proven aerosol leak testing systems.
The use of Automatic Test Waterbath is one of the most popular methods to check the tightness of aerosol cans. The unit consists of a bath unit, drive unit, dryer and control cabinet and does not require an additional operator. The aerosol cans filled with the product, slowly passing through the bath, are immersed in water at 60°C for 3 to 5 minutes. If any of the cans is leaking, it should explode at this point. Leaking cans are removed from the production line. After leaving the bath, the containers are dried by a high-pressure air stream. Solmatic currently offers three automatic baths adapted to production lines with different capacities. Each unit is capable of performing leak tests on 60, 80 or 120 cans per minute. Such a system - although proven and effective - is, however, quite energy intensive. It requires about 1000-1500 litres of water to be brought to a high temperature and maintained at that temperature at all times.
Aerosol manufacturers are constantly looking for new and better ways to test aerosol tightness. At Solmatic, we have developed an innovative device for an individual order of one of our customers in Poland - a can leak detector (gas presence detector gate). The device is used to check gas leakage from aerosol cans on the existing process line and eliminate cans with gas leakage from further production. The gas sensor gate cooperates with a transporter on which aerosol cans inspected by the gate are moved. Our device is equipped with eight highly sensitive sensors which examine the gas spectrum. Aerosol cans filled with gas are transported through two test stands. If the sensor detects gas, it means that the can is leaking. The defective unit is blown off the conveyor by a compressed air nozzle and falls into a container at the bottom of the unit, from where it is picked up by the operator. The leak sensor is the first device of its kind developed at Solmatic. Our goal is to continuously improve this technology to make it a cheaper and more energy-efficient alternative to traditional methods of aerosol container leak testing in the future.
The Laboratory Test Waterbath (manual) is the equivalent of the Automatic Test Waterbath, which carries out tests on a smaller scale. The unit is operated by a single operator. The unit holds eight product-filled aerosol cans. The operator uses a lever to immerse the test cans into the heated water to visually detect leaks in the test cans and eliminate defective units from the production line.
