Le bas entretien et les bas coûts de fonctionnement

Failure to detect leaks in lids leads to massive re-checking jobs or customer complaint. 100% light testing with Sencon’s on-press End Light Tester Package ELTP will find leaks that have a detectable light path through the fault. But more complex faults - like rivet cracks - may not allow light to pass and will go unnoticed. An additional gas pressure test is needed.

MLT is a real time testing unit designed to detect these ‘micro-leaks’. The system works at the limit of dry seal capability, while at the same time avoiding product damage. Sencon believe that MLT achieves the best mix of sampling speed and test sensitivity, offering the most practical and economic solution to detecting micro-leaks in can lids.

High Sensitivity

MLT discriminates leakage in 0.01cc increments with a typical detection threshold of 0.05cc /10 seconds on 202 lids in the manufacturing environment. Detection can be set as low 0.03cc if the seal surfaces are cleaned more frequently.

High Sampling Rate

The online MLT can test 2.4% of production output with a press speed of 750 ends per minute, per lane.

Low Maintenance, Low Running Costs

Once installed, MLT keeps running reliably. Regular wiping of the test chamber seals being the only maintenance required.

Class Leading Performance

MLT offers 10 to 100 times increase in test resolution compared to previous pressure change test systems.

Low False Rejects

All lids rejected by a tester demand extra attention to confirm the leak and initiate the appropriate action. False rejects therefore waste time through unnecessary investigation. Based on detailed research, MLT is set by default to work at realistic detection thresholds in order to avoid rejecting good product through active monitoring of background noise that allows the system to operate at maximum sensitivity while ensuring minimum false rejects.

Intelligent Sampling for Complete Protection

MLT can automatically adjust its sampling rate to ensure that ends from all belt pocket are being sampled. Sampling from the line at regular, fixed intervals could mean that ends are
tested from only one group of belt pockets, as the belt and the sampler fall into synchronisation. To avoid this, the on-line MLT has an option called “walk the belt”, which monitors and varies the sampling rate to ensure that lids from every belt pocket are sampled. In this mode, the average sample rate is 15 lids per minute, but overall protection against faulty product is effectively greater.

Real Leakage Rates Displayed

MLT not only indicates traceable leaks, the system is configured to display actual leakage rates expressed in cm3 (cc).

Flexible Installation and Modular Expansion

MLT is a modular system, enabling budgeted purchases and fully compatible system expansion. From 1 to 4 heads can be installed to suit different press configurations.

Avoiding False Rejects

Lids rejected by a tester demand extra attention to confirm the leak and initiate the appropriate action. False rejects waste time through unnecessary investigation. Based on detailed research, MLT is set to work by default at realistic detection thresholds that avoid rejecting good product.
