TASK 6 First technique Second technique Materials used Different metals are used for different products. Some of the commonly used metals are, Mild Steel, Carbon Steel, Stainless Steel, Cast Iron, Aluminium, Copper, Brass, Silver, Lead etc. Ceramics are used for various products. Ceramics are made from organic and non-metallic and are mixed with graphite, diamond, carbon, barium Cost The cost of manufacturing products from metals is the most expensive. Also, the process for metals with higher melting temperature will be more expensive as more energy is required in order to melt them. The cost of manufacturing products from ceramics is quite reasonable and is much cheaper the manufacturing products from metals. Also, the process of manufacturing is much shorter and easier them the process of metals. Amount of time taken The amount of time taken depends on the process used for manufacturing. Usually the products made by sand casting take the longest as the process is very long. The longest section in this process is the part of making the mould. The amount of time taken depends on the type of process used (e.g. Slip casting, ceramic shell casting etc.) but the overall time taken to manufacture products from ceramic is less as compared to that to metals. Complexity The complexity of products made from metals depends on the type of process used in the manufacturing of that product. For example, if the injection process is used for the manufacturing, a complex shape
* Copper, gold and aluminum are all alloyed with other metals to make them harder.
For the industries the larger equipment is used which is made up of metal or ceramics.
My role as a teacher is to create stimulating classes giving the learners the opportunity to develop and achieve skills associated with ceramics practices. I start by firstly understanding the assesment criteria set out by the AS board,
How long does it take to make a Steinway piano? How many parts make up a piano? It takes nearly one year to build a Steinway piano following the model of making the world's finest piano. A handcrafted Steinway contains more than twelve thousand parts.
The fabrication of a mold takes two to four weeks, depending on the amount of work the machinist already has scheduled, even though the fabrication process itself takes only three to five days. There are 13 master machinists in the company, and it is always the same machinist who was assigned to the design team. This means an unequal amount of work is distributed among the machinists. The estimated time for this step can be further shortened if the use of resources can be managed effectively.
Pipe charges are different from castings charges for two reasons. The chemical composition of ductile iron pipe is different from ductile iron castings, and the pipe-making process has a higher yield (over 80% vs. 50% to 60%) than the castings process, therefore leaving less ductile iron return available for remelting.
Bakelite's molding process had a number of advantages. Bakelite resin could be provided either as powder or as preformed partially cured slugs thus increasing the speed of the casting. Thermosetting resinsof Bakelite though require heat and pressure during the molding cycle, but without being cooled it could be removed from the molding process, hence the molding process becomes faster [36]. Because of the smooth polished surface that is obtained, Bakelite objects required less finishing. Bakelite can be molded very quickly thus it is good for mass-production of identical units. Moldings are smooth, retain their shape and are resistant to heat, scratches and destructive solvents. Phenolic resin products may swell slightly under conditions of extreme humidity or
3D printing uses a process known as "additive" manufacturing. That means that the solid, three-dimensional object constructed will be made by adding the desired material in layers. The first successful outcomes of additive printing occurred back in the 1970’s. One of the advantages of using additive printing is that it takes less time than having to get a big enough piece of material and then making a mold before starting the process.(Additive) Those both also add to cost which is saved using this process. Also, there is a
Manufacturing is a step of process used to convert raw materials into some useful part or product. In our day to day life the parts or a product that are used which are manufactured or derived from another materials it is fundamental objectives for all the problems, and these parts are manufactured by using some of the equipments.
Ceramics originated in the Shang dynasty and persisted throughout classical China and still has a substantial impact in the modern day. However, The first porcelain was produced in the east which was where the Han Dynasty was located. The Chinese appreciated this item because it defined classical pottery in the Neolithic cultures, the bronze age etc. It was typically made of porcelain clay or pottery stone threw different processes such as proportioning, molding, drying and firing. The artifact you see above in blue and white is the normal look of porcelain pottery pieces back then because that was the design that was first produced which became a known representative from then to now. It also promoted economic and cultural exchange between
There are various materials which can be used on aircrafts. Composite and alloy materials are the primary component used due to the ability to combine certain materials with different strengths together to create a composite or alloy. These have ultimate properties that are needed to create an aircraft to be used safely in application. Composites are used due to the extreme high strength to weight ratio, although using large amounts of metals can be strong, unlike composites this would be too heavy. Composites essentially are designed to create a lighter aircraft, which over a long period of time, would be more cost effective for company running the plane, due to fuel savings.
Porcelain tiles have a long history of being one of the favorite flooring materials in the average household, due to its durable characteristics, low maintenance cost, wide range of styles as well as resistance to wear and tear. Porcelain tiles are a branch of ceramic tiles that is made in a slightly different method with different ingredients. The manufacturing process of the tiles involves clays and other components fired together at intense temperatures to produce porcelain tiles. Originated in China, as the time goes on, the demand for porcelain products like china crockery increased and became more popular. As the popularity of porcelain began to grow and spread throughout the world, slowly many countries began to manufacture porcelain. In the early 1700s, they were being used in monumental buildings like churches and parliaments. Even though this traditional product may look simple, behind it lies a long and complicated manufacturing process.
Ceramic Matrix Composites are composed of a ceramic matrix and embedded fibers of other ceramic material (dispersed phase).
In the new global economy, the development of traditional ceramics industries has become a central issue for individual ceramicists and craft enterprises alike. In Oman, over the past decade the Public Authority for Crafts Industries (PACI) has played a strong role in supporting the traditional ceramics industry. However, recently, competition from imported pottery and the negative impacts on local markets has become a pressing issue. The purpose of this paper is to address the ways in which individual Omani ceramicists and traditional pottery enterprises can successfully compete against imported ceramics.
• Casting is one of the earliest manufacturing process. It is the first step in making most of the materials.
