1.0 - Introduction
When designing an engineering component, the right material is selected based on a combination of properties, processing characteristics, sustainability and performance. Selecting the perfect blend of materials will fetch great benefits to any engineering business such as lowering costs, reduce failures and bring significant advantages over the competition.
However, the process of material selection is an extremely complicated matter. A wide range of material types and manufacturing methods available to be chosen from. Furthermore, there are other design requirements such as the economical factor, safety, performance and aesthetics, as well as environmental impact and sustainability.

It has many advantages over the other materials. Several properties that favor its use in the making of tyres are:
1. Abrasion Resistant Surface
2. High corrosion resistance
3. Extremely Durable
4. High Heat Resistance
5. Cheaper material
When compared with other material used to make tyres such as natural rubber and wires, Styrene-butadiene Rubber given above is cheaper as well as has a very low amount of abrasion which allows it to serve its purpose.
4.0 - Sustainability Issues
Styrene-butadiene rubber will not decompose easily because it has a very high melting point. Since Styrene-butadiene rubber contains only Carbon and Hydrogen atoms, burning of Styrene-butadiene rubber will produce CO2. This is harmful to the environment. But the main advantage is that it can be recycled. So therefore it can be used again.

5.0 - Processing Techniques
Processing techniques firstly include the gathering of raw materials. Next the raw materials are mixed together. Then the materials are prepared by extrusion, calendering and bead building. Then they are sent to the the tyre building material.The tire building machine pre-shapes radial tires into a form very close to their final dimensions. Afterwards it is sent into the curing process.The curing press is where tires attain their final shape and tread pattern.Finally, the tyre is inspected by automated machines to ensure the final outcome is
We use metals to construct all kinds of structures, from bridges to skyscrapers to elevators. The strength as well as durability of materials that are crafted out of metal make the materials ideal not only for construction but also for many other applications.
A key difference that we can observe is that in the mentioned processes, instead of having a piece of raw material and using tools to cut, drill and remove parts from it until obtaining a desired shape, these techniques build the product layer by layer and thus generate little to no waste compared to traditional methods. Whereas elimina...
Bias ply tires are composed of multiple layers starting with nylon plies at 45 degree angles to the bead in order to form the carcass. Each of the nylon plies is covered with a rubber cushion along the wire bead in order to protect them from tearing while under tension. Enveloping the carcass of the tire is the tread and the sidewall both of which are made of rubber. The threads and sidewall of the tire are made by injecting rubber into a mold. Rubber is used because it is a very versatile material that can withstand the large amounts of friction involved in landing a
Forging is a faster process than casting therefore; the continuous product of the forging will be more reliable. On the other hand, the forging machinery will sometimes require metal-forming dies therefore; the machine will have to reach the correct temperature to properly shape the pieces. The only difference is that the two methods have different processes which manufactures the product such as the forging process basically involves shaping the raw material using compressive force whereas; casting is a way that the raw material has to be liquefied an poured into a mold and the shape is made correctly. There are many limitations to using a casting machine to a forging for example, the casting’s advantages is that any type of metal could be used to cast which is good however, the company will only be using one for its method to manufacture a wrench significantly, any size of casting could be produced which suggest heavy products could be used up to 200 tons. Furthermore, casting is the best machinery to use to composite components
Many different stakeholder groups have expressed opinions that either favorably or negatively view Styrofoam, but the positions taken by the owners, customers, and the
There are many obstacles to coming up with a good design for engineers. Taking an ethical approach, one should be able to assume that the design they asked for was given due diligence and put together by a team of professional engineers who live by the Code of Ethics for their professional organization.
Polymer-Polyethylene is partially crystalline as well as amorphous because it has crystalline and amorphous regions. Also it has linear chains so this is the simplest structure compared to a branched or network chain. This can be of an advantage to it over other types of materials as its good toughness and elongation makes it very significant in the engineering industry as it can be moulded or extruded into shape...
Some of the key parts of any bicycle are the frame, forks and wheels. The most common type of bicycle frame is known as the double diamond. It is called this because if you look at the frame, it is diamond shaped with 2 smaller triangles forming the front and rear. This designed has endured because it is easy to build, strong and efficient. The tubing that a frame is made with is usually round but can be many different shapes even on the same bike. The reason for this shaping is to increase the rigidity or improve the ride quality. For instance, the sloping tube that goes from the front of the bike to the pedal junction of the frame is sometimes ovalized along the horizontal axis at the pedal junction to make the frame flex less side to side. Frames have been made from many materials including wood, steel, aluminum, titanium and carbon fiber just to name a few. Each of the materials have a strength to weight ratio, tensile strength and cost of production that must be taken into account before deciding which will work best. For example, when a frame made of beryllium was introduced, the strength to weight ratio was very high. The weight was extremely low but the cost wa...
Extruded is cheaper, a lot of ductile, and most well-liked for bending and forming. Acrylic is additionally obtainable in
Product formation is the widely usage of 3D printing since it provides cheap test out of dimensional products for designers and engineers before producing by expensive tool and manufacturing process.
Material handling system is an important equipment and in the design of an effective manufacturing design. One of the main tasks in material handling system design is the selection and setup involving apparatus, demanding comprehensive technical understanding along with methodical research. Material handling equipment selection is a very complex and tedious task. The main factors contributing to the complexity of the equipment selection problem is the constraints imposed by the facility and materials, a variety of disagreeing design and style requirements, anxiety inside functional environment, and some of equipment varieties in addition to designs accessible. In recent years, the equipment selection
Material handling plays an important factor in moving, storage and the control of goods. It can also be said as the equipment used to handle the cargoes. Goods are different in types and shapes. Material handling is intrinsically associated with production flow. Material handling can be classified into two categories (1) Traditional; In traditional it is more towards using human power and is usually minimize since it depends on the capabilities of the human to handle the task. (2) Modern; in this category is it related more to using robotic
Materials engineering and computer engineering are two of the modern examples of industrial engineering. Industrial engineers have the challenge of incorporating today’s leading technological advances with the production of them in manufacturing facilities. Their purpose is to maximize output, while minimizing the costs for materials and production. This is why industrial engineers must have knowledge of product development, materials processing, optimization, queuing theory, production techniques, and engineering economy. Industrial engineers must have adequate skills in computer aided design and computer aided manufacturing.
