Process vacuum
Leak testing
Many parts and systems must be airtight to operate correctly. Vacuum is a fairly common method of conducting leak tests. When vacuum is applied, any leaks are detected by small changes in pressure.…
Vacuum forming
During vacuum forming (thermo-forming), the ambient atmospheric pressure is used to form/press pre-heated plastic sheets over a mold. Air is rapidly evacuated from the mold by a vacuum pump and a..…
Evacuation and filling of liquids
In final assembly of certain machines/products like cars and refrigerators, fluid systems are filled before the machine/product leaves the manufacturing facility. To speed up the process of filling…
Vacuum lamination/bagging (vacuum infusion)
During the manufacturing of laminated products like veneer sheets and plastic hull of a a boat, vacuum is used to eliminate bubbles and thereby increase the material strength.
Vacuum packaging
Many food products including meats, poultry, coffee and produce are often packaged under vacuum in order to extend their shelf life. In Modified Atmosphere Packaging, MAP, a gas is introduced into …
Vacuum for instrument calibration
Vacuum is used for simulation of different atmospheric pressures and different altitudes for instrument calibration. Advantages with Piab No service required on Piab vacuum pumps Easy adjustable...…
Vacuum drying
Removal of liquid from a solid material with the aid of vacuum. Drying with vacuum is often used when products are sensitive to heat (cause oxidation), to recover toxic material or if the final...<…></…>
Evacuation of molds
Vacuum is applied on mold cavities to give molded products a better definition. Advantages with Piab No service required on Piab vacuum pumps Low noise level Easy to install
Evaporation/crystallization
Vacuum is used to reduce the point of boiling so that an optimised temperature and pressure can be applied during evaporation or crystallization of liquids. Advantages with Piab No service required…
Filtering of liquids
Vacuum is used to achieve a wider differential pressure of a filter material to get a more effective and faster filtration. Typically used in applications where liquids are separated from solids...…
Degassing
To achieve an effective degassing of oils and other liquids, vacuum is used. The largest possible surface area is exposed to vacuum. Advantages with Piab No service required on Piab vacuum pumps Ea…
