Here at Premier Die Casting we use a number of machines during our assembly and testing procedures. Using assembly machines promises to produce the best products as quickly as possible. This method has been so successful it has been adopted by nearly every industry today, as virtually all car industries use machines in their assembly process. Other products are tested with a network analyzer, which allows us to examine the output of electrical equipment.
Not only will you see productivity increase through the use of mechanical assembly, you will also see quality improved due to the number of pressure tests that are taken. While network analyzers require a special tech, the information gained from the testing is very valuable. The findings can determine whether or not the product is fit for the market or flawed.
Below we will address the different kinds of pressure tests that are used, and explore the findings we can get from network analyzers.
So why do we care about pressure testing our products? Well, pressure tests are important because they give us reassurance that nothing went wrong in our production process. Testing is used as a safety precaution, but it also ensures that our products are reliable and free of leaks.
In this case we can use two different methods to pressure test our products: hydrostatic and pneumatic. The first method uses water, while the second uses air or any type of alternative nontoxic gas.
Think of it this way, if you have a balloon that is shrinking but you are not sure if there is a leak of not, what are you going to do? Well, for starters you can submerge the balloon in water to see if there is a leak. If there is in fact a leak the point of conflict may bubble. If the leak bubbles that is an example of a simplified (and reversed) air test because it pinpoints the exact cause of the problem.
Network Analyzers are mostly used with electrical equipment, because it is mandatory. The system operates by using the reflection and transmission rates of electrical networks. These variables tend to vary as frequency fluctuates. Monitoring the frequency will tell us at what level the product is operating at, if it is at optimal efficiency, or whether or not there is an issue.
In the case that the device is operating efficiently it will be approved. When the device fails to operate efficiently, it will not be approved. The analyst in accordance with the network analyzer will allow us to trace the issue, and correct it.
