Metal products and components cannot last long in their bare form, which is why surface treatment becomes necessary. There are various methods for surface treatment, such as painting, plating, thermal spraying, heat treatment, and vacuum film coating (vapor deposition). Among these methods, vacuum film coating (vapor deposition) requires a high vacuum environment and improves hardness and wear resistance.
Vacuum film coating (vapor deposition) methods can be broadly divided into two groups: Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). PVD is a deposition method where solid materials are vaporized by heat or plasma and the vapor condenses on the surface to form a coating. Depending on how the solid material is vaporized, it can be further categorized into thermal evaporation, ion plating, and sputtering methods. On the other hand, CVD uses chemical reactions where a precursor gas containing the elements for
The NeoDry G Series of dry vacuum pumps is the newest addition to the Kashiyama pump product line.

The Role of Mass Flow Controllers in Precise Gas Control
In vacuum furnaces, mass flow controllers (MFCs) are crucial for precise and stable gas flow control, ensuring accurate atmosphere control and preventing oxidation, especially during processes like carburizing, annealing, and CVD. In this blog, we'll explore the in's and out's of MFCs.
Purpose of MFCs:
Vacuum furnaces require precise control of the gas environment to achieve specific outcomes, such as preventing oxidation, maintaining a specific atmosphere for a process, or controlling the chemical composition of materials. MFCs enable this by accurately controlling the flow rate of gases like nitrogen,
A cryopump is a mechanical device that uses a freezing process to remove gasses and vapors from a sealed space. It is commonly used in chemical laboratories and other environments where it is critical to maintaining a high level of purity. In many cases, cryopumps are used in conjunction with other types of pumps to create an ultra-high vacuum. When operating, the cryopump draws in gas molecules and then cools them to such a low temperature that they liquify. The liquid then falls into a holding compartment, leaving the area being pumped virtually free of atmospheric contaminants.
How does a cryopump work?
Cryopumps use a cryogenic pump head to remove gasses from a system. The pump head works by condensing the gas onto a cold surface, usually made of metal. The gas is then drawn into the pump body by a vacuum, and the cycle repeats.
This process is typically used in high-vacuum environments, such as those

Maybe you’ve been in the vacuum and component industry for decades. Maybe you’re new, or learning the ropes. Whether or not your expanding your expertise, or simply shopping for vacuum components, you should know how to differentiate the most common terms and products for your application.
IES Technical Sales works with some of the world’s top vacuum manufacturers and component manufacturers.
That’s why we are sharing this robust glossary for ultra high vacuum terminologies. Here, we’ll define the vacuum vocabulary and the most common items you will come across in the industry.
Analytical Instrumentation - Any device or appliance that measures the composition, structure, or properties of a substance. Vacuum is used in analytical instruments such as mass spectrometers, chromatographs, electron microscopes, and particle accelerators to create low-pressure environments for accurate analysis and observation of
ConFlat flanges and fittings are part of the family of ultra-high vacuum (UHV) components that compress a copper or elastomer gasket between two stainless steel flanges to create a vacuum-tight seal. But, if a tight seal is not maintained, or if it is improperly placed between flanges, UHV pressure will not be maintained.
This ConFlat flange guide will take you through the steps for how to install these flanges onto your system to ensure it runs smoothly and effectively.
Before moving on, wear proper gear, like lint-free gloves when handling any part of vacuum components that eventually encounter any part of the vacuum atmosphere.
Step 1: Cleanliness Examination
Examine both flanges for cleanliness and that sealing surfaces have no dents or scratches. Any damage, in the form of scratches, dings, dents, etc. OR debris, such as dust, lint, dirt, etc. can affect the integrity of the vacuum seal.
ISO centering rings are inserted between two flange faces and secured with an encompassing flange clamp. The included O-ring provides the vacuum seal.
Centering rings from IES are sourced from leading suppliers. They are precision components constructed from durable materials, such as 304 stainless steel and 6061 aluminum, ensuring dependability and reliability over time. ISO centering rings from IES are designed for ease-of-installation and low maintenance properties, helping to make them a convenient solution for a variety of applications.
Bonded door seals for gate valves and slit valve door seal applications provide improved sealing performance versus conventional O-rings by reducing particle generation, extending seal life and minimizing replacement time during preventive maintenance.
DuPont™ Kalrez® bonded door seals are designed for easy installation and low particle generation. They combine a custom seal design and proprietary adhesion technology along with the excellent plasma resistance of Kalrez® perfluoroelastomer seal materials developed for semiconductor applications. The seal is held in a “fixed” position versus conventional O-rings, thereby eliminating “rolling/twisting” and abrasion during door actuation. In addition, the seal design has been optimized using finite element analysis (FEA) to minimize high concentrations of localized stresses. As a result, both particle generation
