Vacuum System Leak Detection
Leaks in a vacuum system can be defined as an undesired gas flow and may be proven to exist as well as pinpointed for repair by applying leak detection techniques. When assessing vacuum system performance, leaks can be a frustrating aspect of operations. There are several classes of leaks: True leaks – cracks or holes allow […]
Types of Vacuum Pumps
When designing your vacuum system, one of the most important choices you need to make is the type of pump(s) you’ll use. When designing your vacuum system, you want a pump that will remove gas particles, not introduce contaminants, and not affect its surroundings by introducing stray electric or magnetic fields. Ideally, pumps should be […]
Critical Infrastructure – The Care and Feeding of Suppliers
Ever have a supplier miss a deadline? Was it a big one? What did it cost you? Supplier failures are an all-too-common fact of business, and as easy as it may be to villainize suppliers for failures, sometimes it is simply out of their control. Shipments stuck in customs, logistics hang-ups, and mis-entered purchase orders […]
Vacuum System Pretreatment and Cleaning
Achieving the ultimate pressure of a vacuum system is greatly affected by the amount of gases or vapors contained within the system. To improve initial pumping efficiency following assembly or maintenance activities, outgassing can be reduced by properly pretreating the components within the system. The higher the ultimate pressure specification, the greater the need for […]
Selecting Materials for Manufacturing Vacuum Systems
Material selection is crucial in all aspects of a vacuum system, especially when using precision fabrication equipment to build vacuum chambers. Vacuum chambers play a big role in precision fabrication where maintaining controlled environments is essential for processes. In a vacuum vessel, the walls must be strong enough to withstand the pressure difference of the […]
9 Main Processes Used for the Deburring and Finishing of Metal Parts
Deburring is the process of chamfering or rounding sharp corners formed on a metallic part during the machining process. Deburring can also remove the raised edges and small pieces of material that may remain attached to a workpiece after it has been machined by a cutting tool or grinding wheel. Finishing processes alter the surfaces […]
