Articles about Castings, Machined Components and more!

The history of mechanical engineering is as old as civilization. Indeed, humanity would never have been where it is right now without the invention of manufacturing processes like castings and machined components.

Stay with us as we explore this subject via interesting articles in this knowledge base.

Castings Basics

Casting is a mechanical process whereby a molten metal or its alloy is poured in a mould and allowed to solidify. The object then gets the shape of the mould.

Castings are integral to the engineering industry, and have been in use for the last 6000 years. Casting....

Ductile Iron Casting - The Process

Ductile iron casting refers to a process in which magnesium / Cerium (as an alloy of magnesium / Cerium) is added to cast iron. It was first manufactured by K.D. Mills in 1943. While most varieties of cast iron are comparatively brittle, ductile iron castings are much more ductile due to the in....

Flywheel Flanges

What are Flywheels?
Flywheels are mechanical components that store kinetic energy and convert it later into circulatory motion. Essentially, these are big wheels that require a lot of momentum to start, but once they start are hard to stop. This momentum is typically used in situations wh....

Gear Cases

As we have seen elsewhere, there are various types of gears like spur gears, bevel gears, rack and pinion, helical gears, etc. By their very definition gears mesh with each other. It is therefore very important to keep the teeth and the meshing area free of anything that interferes with their workin....

Spur Gears, Helical Gears, Bevel Gears and Worm Gears

Gear Cases
A gear is a mechanical component with tooth members that transmit either power or motion between two shafts. The teeth of the gears mesh with each other without slipping. When two gears run together, the one with the larger number of teeth is called the gear and the one with sm....

Machined Castings

Machining is a material removal process (like cutting, grinding, etc.) that uses some sort of cutting tools to produce the desired size and shape in an object. The object is typically cut from a larger piece of stock, which is available in a variety of standard shapes.

Castin....

Machined Components

Machining is a process that uses tools like milling, shaping, drilling, etc. to work on material to give it different shape or size. Machined components are widely used in all industrial products. They came to the fore after the industrial revolution of the 18th century. Machined components are made....

Pump Housings

A pump is a mechanical device that provides sufficient pressure to move the fluid through the system at the desired flow rate. It is therefore a means of transforming mechanical work into fluid energy. Pumps can broadly be classified as centrifugal pumps and positive displacement pumps. By far,....

Rotors

Rotors are defined as any mechanical parts that rotate. Rotors are ubiquitous - they are used in diverse applications like turbines, turbopumps, centrifugal pumps, fans, centrifugal compressors and other thermal and hydraulic machines. They are also used in many synchronous and asynchronous ele....

Windmill Hubs

Introduction
We have been using windmills as an alternate form of energy for a long time now. Scientists have experimented with many designs, shapes and number of blades for a windmill, but have more or less finalized on a three blade design now.

Windmills ca....

Applications of Ductile Iron Castings

Cast iron is an alloy that contains more than 2 to 2.5% carbon. It is also called as grey cast iron. The second type of cast iron is ductile cast iron that contains magnesium in addition to the carbon. As the name implies, ductile iron castings are more ductile than the normal cast iron. While ....

Effects of Various Elements in Ductile Iron Castings

Ductile iron has grown in prominence as the chosen material in castings. It is highly tensile, has excellent castability and better mechanical properties than cast iron or gray iron. It also is low cost casting material.

The properties of ductile iron castings depend on....

Mechanical Properties of Cast Iron

Cast iron is an alloy of carbon (over 2%) and other elements. The rigidity and dampening factor of cast iron make it an excellent material for machine tool frames and parts.

There are many ways of classification cast irons. Some of the common classifications are based o....

Inoculation of Cast Iron

Inoculation is an important process in the production of cast iron. Essentially, inoculation means fast cooling of the cast iron production to enhance its qualities. This is done by the introduction of fine nuclei (less than or equal to 4 micron) of desired element that influences the structura....

Heat Treatment of Ductile Cast Iron

The Heat Treatment Process
Mechanical properties of alloys and castings are structure-sensitive. Their magnitude largely depends on size, shape and distribution of various micro constituents. These mechanical properties can be changed quite drastically by varying the relative p....
