Singapore Estes Engineering Pte Ltd

We are offering high pressure leak tester. The estes est-p series product is an advanced leak testing system for empty aerosol cans. An infeed star wheel leads the empty aerosol can onto the machine. Then the aerosol can go into the tester chamber. In the aerosol can, a pressure of up to 8-12bar is created. Any leakage of the can even micro leakage will cause a pressure difference in the test chamber. This pressure difference will be detected by a high accuracy pressure transmitter and measuring system. The system will give a signal to let the leakage can be blowed out when it pass the exit. it is a best replacement product for the water bath tester.

We are offering vacuum leak tester. this machine is to be installed directly on the production line, on line eliminate the defective cans (with pin holes, cracked welding, dented flanges etc.) the working principle of this machine is: detect and get a first pressure value after the cans vacuumed when the cans pass through the working heads, keeping some time, then detect again to get a second pressure value, by the calculation of the plc, compare with the machine setted standard value. If the value is in the standard range, the cans will pass smoothly and go into the next procedure palletizing; if the value is not in the standard range, then means this can is a defective can and will be rejected automatically on the outlet conveyor and collected to a container for factory analyzing use, this is the whole detecting procedure.
