Gelatin is a translucent, colorless, brittle (when dry) and flavorless solid substance which is derived from the collagen. Mainly inside cow skin (hide) and bones. It is commonly used as a gelling agent in food, pharmaceuticals, photography, and cosmetic manufacturing.Substances containing Gelatin or functioning in a similar way are called Gelatinous. Gelatin is an irreversibly […]
3D printing uses different types of processes to manufacture parts and prototypes for wide range of applications. This process is quick and cost effective. In order to produce parts with different mechanical properties and usage, we need different kind of 3D printed materials. This article will help you to choose right material for process and […]
3D printers need to convert the 3D models into printable file format. A slicing software can do this job. It converts the STL file into layered structure. The 3D printer slicer or slicing software converts 3D model in STL format into G code format. The slicer first converts object into stack of layers followed by […]
3D printing is changing the way we make things, especially when it comes to creating physical products. This is a learning path that will cover the history of 3D printing, as well as how business and consumers can use additive manufacturing to their advantage. Many different manufacturing technologies are used by engineers to produce different […]
KF Assembly The KF or NW vacuum fittings consists of two identical flanges, a center-ring and an aluminum clamp. This assembly has a wingnut fastener which helps to frequently connect and disconnect without any tools. The KF or NW flange surface have 15o angle. This helps to create effective vacuum seal by clamp. The mating […]
Carbon Carbon occurs in different forms. For example, diamond, graphite, carbon nano-tubes, fullerene and graphene with different bonding and structures. Same carbon cab be used to make synthetic diamonds by chemical vapour deposition process. Graphite and diamond are most common forms of carbon and on the other hand graphene is recent development with new applications. […]
Plasma Enhanced CVD is a chemical vapour deposition process which deposits thin films. In this process deposition takes place from gas state to solid state on a substrate. Reacting gases creates plasma which helps for chemical reactions. The Plasma Enhanced CVD process takes place at 250 to 350 °C and because of low temperatures the […]
Low pressure chemical vapor deposition (LPCVD) is a deposition technology that uses heat to initiate a reaction of a precursor gas on the solid substrate. This reaction at the surface forms the solid phase material. Low pressure (LP) is used to decrease any unwanted gas phase reactions, and also increases the uniformity across the substrate. The […]
Documentary letter of credits in import/export business A documentary credit in international trade represents an irrevocable commitment by the bank to pay the seller for goods or services. The amount of payment and time period are mentioned in credit documents. Documentary credits are and essential part in world trade today. It is a better way […]
Atmospheric Pressure Chemical Vapour Deposition is a CVD method. A Basic CVD system can typically broken up into the following three components (1) precursor delivery; (2) the CVD reactor; and (3) exhaust management. As we explained in CVD article above. Atmospheric Pressure Chemical Vapour Deposition is a CVD method at normal pressure (atmospheric pressure). Which […]
