Vacuum Simulation of Aerospace Parts using a two-door Chamber
A Vacuum Chamber is vital when it comes to testing of aerospace equipment and parts. The obvious reason is because space or anything at higher altitudes will be subjected to a pressure differential as compared to sea level pressures. A vacuum chamber not only allows for performance testing of aerospace parts, it also allows for quality and leak testing of such parts. Acrylic is preferrable because acrylic is fully transparent allowing for full view of product during the vacuum test.

An aerospace company had a need to both leak and quality test the parts they were making. Our vacuum chamber was used two-fold; 1. To create a pressure differential (vacuum) and leak test the parts. 2. To create a vacuum and performance test their parts to see how these will behave and perform at different vacuum levels. In order to improve production thruput and efficiency, another requirement they had is that the chamber needed to be accesses from two opposing walls. What you see here is a 20-inch inside dimensions, acrylic vacuum chamber with two-doors. One door is placed on the front wall while the other is placed on the rear wall. Both doors are hinged and front loading. The means that the vacuum chamber can be placed on a table top and accesses from both directions of the table. When the first operator places the aerospace part into the vacuum chamber, and after the vacuum test has successfully completed. The aerospace part can now move onto the next step. The second operator can now open the door from the other side and take out the aerospace part. The business manager is happy with the time savings because the second operator does not have to walk around the table to reach the part after the test has completed. The quality manager is happy too because the part will travel less distance and the risk of dropping or mishandling the part has been reduced.

If you are looking for a custom vacuum chamber or a custom vacuum system, you are at the right place. We have been making vacuum chamber systems and our customers happy since 2008. Contact us to find out how we can help you.

Vacuum Decay Leak Testing Systems
Vacuum Decay Leak Testing Systems are Instruments that detect and quantify a leak by measuring the drop in vacuum (pressure) inside the specimen. During a vacuum decay leak test, the specimen is placed into a vacuum chamber, the vacuum is pulled to a specified setpoint, and the drop in vacuum is monitored and recorded over time. If a leak in the specimen exists, the air will travel from a higher pressure (inside the specimen) to a lower pressure (vacuum chamber). As a results of the additional air, the vacuum levels will drop whereas a leak can be detected and quantified.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Pressure and Vacuum Chamber used for Calibration of Weather Stations across the US
Have you ever wondered how the weather forecast works? You must admit; the weathermen (or weatherwoman) have become a whole lot more accurate over time. 10 years ago, the weather forecast was not as accurate as it is today. Part of the reason is that we have better forecasting technology as in more powerful computers who crunch numbers faster to out a most likely scenario. Another reason is that mathematics, physics, and science has progressed. The main reason however, is that we have better tools and equipment.

Visual inspection is an attractive option because it does not require the purchase of any additional equipment. There are several arguments against Visual Inspection of heat seals; the argument against visual inspection is that visual inspection is subjective, unreliable, operator dependent, or not a valid method of inspection. However, if you have the correct training, procedures, and documentation in place, visual inspection can become a powerful tool in your quest for better packaging.
