Multi Station Stress Crack test for PET bottles
1Pages

Multi Station Stress Crack test • Automatic or Semi Automatic configuration • Compact design, smalf footprint. • Maximum Pressure Set Point 8 Bar • Individual test stations can be disabled if required • Interlocked safety circuit • Upper & lower pressure setpoints programmable * • Adaptors available for most neck sizes/types "Available on Automatic version only A PLC controls the process and monitors each test station. After the bottles are toaded the cycle starts by pressurizing each sample to a pre programmed Set Point pressure. After a programmed time to allow for bottle size creep the NaOH solution is released from the reservoir to the required level around the base of each sample. Pressure in each sample is monitored and the time of failure for each station is recorded by the controller and also exported to a PC. SEMJ AUTOMATIC: After the samples are loaded the user opens a valve to pressurize each sample, (pressure pre set on local regulator). Timing & release of the NaOH solution is by a separate manually operated valve. Monitoring of failure is observed and recorded Somex Ltd, Ballyvourney, Macroom, Co. Cork, Ireland email: info@somex.ie
