Large Punch Press Cylinder Stutters On Downward Extension

An OEM had a hydraulic distributor design an HPU for a punch press he wanted modified to punch large stainless-steel discs that were then sent to a forming press. The final product was the end caps for cylindrical air compressor tanks. After the used press was mechanically upgraded they installed the new hydraulic power unit, […]

Hold It Down – Vacuum Clamping

By Daniel Pascoe President of Davasol,  Inc. Most of the articles I have authored for Fluid Power Journal have been about vacuum pick and place, which is the most common application in fluid power circles for vacuum components. However, a relatively common application for the same components is the opposite of pick and place:  material […]

Low Vacuum High flow

By Daniel Pascoe Most vacuum pick-and-place applications require a moderate vacuum level of about 20+”Hg. For example, a 40-mm diameter cup has a theoretical lifting force at this vacuum level of about 17 lbs. This is of course affected by numerous conditions such as inertia and surface type. There are many options the user may […]

Hold It Down

Most of my previous articles have been about vacuum pick-and-place, which is the most common application in fluid power circles for vacuum components. However, a relatively common application for the same components is the opposite of pick-and-place, and that would be material hold-down or vacuum clamping. Industries such as sign manufacturing, glass production, fiberglass fabrication, […]

Cold Hard Facts: Five Key Criteria for Selecting Low-Temperature Valves

Cold Hard Facts: Five Key Criteria for Selecting Low-Temperature Valves by Bob Cadwell, Business Development Manager, ASCO Specifying and consulting engineers, engineering houses, original equipment manufacturers (OEMs), and end-users depend on valves to control the flow of compressed air or other fluids, and on cylinders to control motion. But the cold truth is that low […]

Vacuum Cup Holders

Vacuum cups are often mounted directly to machinery via a cup fitting as shown in the cup assembly in Fig. 1. This cup fitting will screw into the machinery lifting arms or handling device. If only one cup is being used or a pair to pick up cardboard sheets on a carton-erecting machine, for example, […]

Handling Large Loads

By Daniel Pascoe Most vacuum pick-and-place applications involve the handling of small parts such as semiconductor components or food packaging items, which are very common in industry. Less common is the handling of much larger loads such as roofing panels, drywall sheets, diamond plate floors, concrete sewer pipes, and so on. Although these products are […]

Intelligent Pneumatics Move Fluid Power into the 21st Century

By Frank Langro, Director – Pneumatic Automation, Festo, and Sandro Quintero, Product Manager – Valve Terminals & Electronics, Festo Pneumatic valve technology has remained relatively stable for more than 60 years. Over that period, developments in sealing technology have improved valve service life. Solenoid advances have increased switching speed and reduced power, but the basic directional […]
