Aluminium has an exceptionally broad range of abilities, properties, physical, chemical and mechanical characteristics, which are manifested through an extensive number of alloys.

Briefly on aluminium:

• Very low specific weight. About 1/3 of iron.
• It can be easily shaped, rolled, drawn, extruded, welded and therefore it is the ideal metal for construction. Its module of elasticity (70.000MPa) is 3 times lower than of iron. Under load conditions, an aluminium structure has 3 times greater elastic elongation than an iron ore.
• Aluminium and most of its alloys range from resistant to very resistant against various forms of corrosion. Due to its close chemical affinity with oxygen, the metal’s physical surface is permanently covered with a layer of aluminium oxide, which is a very effective way of preventing further corrosion. It is this property that makes it popular with construction, marine engineering and the transportation industry (automobiles, trains, aircrafts). Its near-to-zero maintenance cost in combination with its low specific weight, make aluminium the ideal choice.
• Aluminium is a good thermal and electrical conductor.

Brass metal has several different applications. As the metal has a similar appearance to gold and is available in a variety of shades, it is often used for decorative & architectural elements. Additionally, the workability and machinability of the material lend it to use in the manufacture of plumbing, electronics, and musical instruments.

However, the alloy does exhibit a few distinct properties compared to pure copper and other copper alloys. For example:

• Susceptibility to stress-cracking: As brass is stronger and stiffer than pure copper, it is more susceptible to developing stress cracks.
• Malleability and formability: Compared to bronze, brass is more malleable. Additionally, it is easy to cast or work.
• High melting point: Brass has a melting point of approximately 900°C. The exact melting point differs based on the concentration of different metals in the alloy.
• Non-ferromagnetic: As brass is not ferromagnetic, it is much easier to process for recycling.

Depending on the additional metals added to the alloy, it can demonstrate varying characteristics, such as a variable melting point or greater corrosion resistance

Forging is a manufacturing process where metal is pressed or forged under great pressure into high strength parts known as forgings. Forged Components are shaped by a Forging Hammers. Forging on the hammer is carried out in a succession of die impressions using repeated Strokes. The quality of the forging components, and the economy and productivity of the Forging process depend upon the tooling and the skill of the operator.

Features:

• Highly endurable
• Excellent performance
• Accurate dimensions
• Rugged construction
• Cost effective

A fastener is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Welding is an example of creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel. The most common types of fasteners are the screw, nut and bolt, possibly involving washers.

The CNC machine tool automatically processes the parts to be processed according to the pre-programmed processing program. We put the processing route of the parts, process parameters, tool trajectory, displacement, cutting parameters (spindle rotation, feed, back-feeding, etc.) and auxiliary functions (tool change, spindle forward, reverse, Cutting fluid on, off, etc.), write a machining program according to the instruction code and program format specified by the CNC machine tool, and then record the content of this program on the control medium (such as perforated paper tape, magnetic tape, magnetic disk, magnetic Bubble memory), and then input into the numerical control device of the numerical control machine tool, so as to direct the machine tool to process the parts.

This entire process from the analysis of the part drawing to the production of the control medium is called the preparation of the NC program. The difference between CNC machine tools and ordinary tool machined parts is that CNC machine tools automatically process parts according to the program, and ordinary machine tools need to be operated by humans. We can achieve the purpose of processing different parts by changing the program that controls the operation of the machine tool. Therefore, CNC machine tools are particularly suitable for processing small batches and complex shapes requiring high precision parts.

Because the CNC machine tool needs to process the parts according to the program, after the programmer has compiled the program, it is input into the CNC device to direct the machine tool to work. The input of the program comes through the control medium.

Punching (Punch & Die) is a forming process that uses a punch press to force a tool, called a punch, through the work piece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal, paper, vulcanized fiber and some forms of plastic sheet. The punch often passes through the work into a die. A scrap slug from the hole is deposited into the die in the process. Depending on the material being punched this slug may be recycled and reused or discarded.

Punching is often the cheapest method for creating holes in sheet materials in medium to high production volumes. When a specially shaped punch is used to create multiple usable parts from a sheet of material the process is known as blanking. In metal forging applications the work is often punched while hot, and this is called hot punching. Slugging is the operation of punching in which the punch is stopped as soon as the metal fracture is complete and metal is not removed but held in hole.

Surface finish can provide durability, protection, and a decorative appearance. Over the next last 7 years we have explored different types of finishes and how they are beneficial for different types of parts.

The Stainless-Steel Fittings are the ones used with seamless pipes to maintain the integrity of the system as a whole. There are standards like the ASME B16 9 Stainless Steel Fittings to govern the nominal sizes of the fittings. The Mss Sp-43 Stainless Steel Fitting for example is a corrosion resistant, low pressure wrought stainless steel standard. There are Stainless Steel Welded Fittings that are used for stainless steel piping. While Stainless Steel Welded Pipe Fittings are common, their variations such as the Fabricated Stainless-Steel Fittings are also used. Depending on the need of the application and the type of the fitting, the materials could differ.

Pipe Fittings are Piping component that helps in Changes the direction of the flow such as elbows, tees. Changes the size of the pipe such as reducers, reducing tees. Connect different components such as couplings and stop the flows such as Caps.

There are different types of pipe fitting used in piping. Pipe Fittings used in piping work are listed below.

• Elbow
• Tee
• Reducer
• Union
• Coupling
• Adapters
• Valve
• Cross

Valves are mechanical devices that controls the flow and pressure within a system or process. They are essential components of a piping system that conveys liquids, gases, vapours, slurries etc.

Different types of valves are available: gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc. Each of these types has a number of models, each with different features and functional capabilities. Some valves are self-operated while others manually or with an actuator or pneumatic or hydraulic is operated.

There are many valve designs, types and models, with a wide range of industrial applications. All satisfy one or more of the functions identified above. Valves are expensive items, and it is important that a correct valve is specified for the function, and must be constructed of the correct material for the process liquid.

Regardless of type, all valves have the following basic parts: the body, bonnet, trim (internal elements), actuator, and packing.

FUNCTIONS FROM VALVES ARE:

• Stopping and starting flow
• Reduce or increase a flow
• Controlling the direction of flow
• Regulating a flow or process pressure
• Relieve a pipe system of a certain pressure

Our gear units have quite a choice of gear-cutting and gear-forming techniques at their disposal, including hobbing, shaping, grinding, broaching, milling and rolling. Every production process is inevitably a compromise between ease of machining, good surface finish, profile accuracy, speed of output and economic production. All metal-removal operations leave minute ridges and scratches, caused by tool shapes or by the motion of rotary cutters; ‘perfect’ profiles and finishes are not obtainable with normal industrial processes. Tooling marks and deep scratches act as stress raisers, which occasionally lead to fatigue failure and tooth breakage. Such a failure almost invariably starts in the fillet radius at the root of a tooth, and may be caused by the use of a cutting tool with too small a radius.

Most gears benefit from careful running-in under light load, since in this way the teeth acquire the surface finish needed for good lubrication and smooth running. In effect, they are given a final production operation, without which the process of surface failure might be initiated as soon as service operation begins.

The life of a gear can also be limited by poor assembly. If a pinion is clumsily pressed onto a shaft, for example, it is likely to operate in an overstressed condition and fail at an early stage, even through running well within its designated rating.

A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. A hinge is useful in mounting glass panels. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom.
