Some can be used for the sentimental task of preserving your child's hand or footprints to waterproofing cables that will be used beneath the surface of the ocean. Instructions 1 Decide what project you are going to do that requires a casting compound. Are you going to be casting your child's handprints or footprints? Are you going to be creating free-form sculptures? Are you going to be creating a particularly large sculpture? Are you going to be creating life casts? 2 Choose the casting compound that best suits your needs. For casting your child's footprints or handprints, you can use something that contains MoldGel Molding Powder, CastRite Casting Powder, which dries and sets easily. 3 Create figurines with art plaster that can also be used to make molds to repair broken sculptures. 4 Do life cast molds with Artform mold material and cement. 5 Use Permastone Casting Compound for creating sculptures that are break-resistant. You can paint it with a wide variety of paints and water colors, oils and more. 6 Make detailed sculptures using Por-A-Kast resin. Por-a-Kast resin can be poured into molds to create sculptures that can cure quickly as well as be drilled, sanded, or ground if needed. You can paint this casting compound easily. 7 Explore Abatron for industrial casting compounds. These casting compounds can be used in many applications from being exposed to radiation or underwater.

The size of the sculpture can be quite small to over 5 feet. However, the process is quite arduous, thereby requiring significant patience and dedication to the project. The results can be a highly professional art piece that can then be painted. INSTRUCTIONS 1 Sketch out your designs to determine what sculpture you will be making. 2 Use wax to create the three-dimensional sculpture of your design. For small fruit-sized models, they should stick out about 2 inches. 3 Poke wax rods or wires into the model (leaving them somewhat exposed). 4 Encase the entire object by dipping it into a mixture of 1/3 plaster and 2/3 sand (also known as the "investment"). The rods will still be affixed to the wax model, but all will be completely covered by the investment. 5 Put the covered wax model on low in the oven, after the investment has hardened, until the wax has entirely melted out. 6 The remaining empty shell is then filled with hot metal. When the metal is solidified, the mold is broken with the revealed sculpture. 7 To paint the sculpture, use metal-safe paints and make your own designs on your new art piece.

Die casting is a versatile process used to create everything from simple parts for small toys to components of complex machinery, and it can be used to make many copies of the same item with no significant differences in each item. Die Making There are many different styles of die that can be used to create parts. A single cavity die can be made, producing an individual part with each use. Multiple-cavity dies are used to create multiple copies of an element, all in one casting. The cavities are connected by thin channels through which the alloy can flow from one cavity to the next, allowing them all to be filled. After casting, the tubes connecting the elements are then cut off, and the metal that connected the pieces is melted down for reuse. Similarly, a unit die is used to create multiple elements that will then be assembled into a single unit. As with a multiple-cavity die, the elements are connected by channels. Injection Once a die has been created, the alloy is injected into it and is allowed to solidify into a final component. The metal is injected into the die and pressed down with high pressure, up to 4,000 tons, which allows it to convert from liquid to solid quickly. This can be completed at both high and low temperatures. Finishing The casting procedure allows for a great deal of flexibility when it comes to applying a finish to a cast metal. The dies can be made to include a surface area that is smooth and can be polished as well as a surface that can be textured if desired. Once a piece has been cast, it can also be plated with another metal. Some metals, such as zinc, are better suited for casting when a plating will be applied after. Assembly The die casting procedure is extremely precise, allowing for the rapid production of many nearly identical parts. The ability to re-create these parts with such accuracy can greatly speed up the assembly process, as a mechanism can be created using multiple die cast elements, and all of the elements will fit together seamlessly as the parts are unlikely to have any defect that will prevent the pieces from fitting together properly.

Fri, 03 Feb 2012 14:06:25 -0600 http://www.metalcastingzone.com/metal-casting-forum/die-casting/pressure-die-casting-process#7111 If you are a model car collector, many of the cars in your collection may have been manufactured by die casting. Die casting allows you to mold metal into various shapes. Before die casting, many metals were welded and hammered together. This resulted in a time-consuming and costly process. Aluminum, iron and lead are alloys that can successfully undergo the die casting process. Although there are other methods of die casting, pressure die casting is considered to be a process that provides accurate and durable molds. Background Die casting is the process of forcing molten metals into mold cavities. The metal hardens and takes the shape of the mold. Tin and lead were the first two alloys to undergo die casting. Before die casting became widely used, plastic molding and sand casting were used to shape metal. Plastic molding resulted in a less-durable and heat-tolerant product. Sand casting results in a rougher mold and a slower production time. . Process Cold-chamber and hot-chamber are the two main die casting process types. Pressure die casting is a variation of the two. During pressure die casting, metal alloys such as aluminum and tin are melted in a furnace. The molten material is injected with extreme pressure into steel molds. These steel molds, or dies, are made prior to the die casting process. They are reusable and recyclable. Cold-chamber machines have an injection piston connected to the furnace. This prevents corrosion better than hot-chamber machines. The injection pistons on hot-chamber machines are immersed in the molten metal. The molten metal is then shot into the mold with extreme pressure and speed. This results in a uniform, durable part that has dimensional accuracy. Uses Die cast alloys are used in many products. Automobile parts may undergo an aluminum die casting process. Die casting aluminum auto parts make them lighter and faster to manufacture. Aluminum is usually cast with silicon and copper because pure aluminum is more susceptible to cracking and shrinking. Mirrors, gas tanks and engine housings are auto parts that are made by die casting. Die cast drum hoops give drums a sharper and clearer sound. Cookware may also be manufactured by die casting in order to make it more durable and environmentally friendly. Advantages Although there are other methods of manufacturing metal products, die casting has advantages over other processes. Die casting results in a smoother surface that you can paint over with ease. You can combine a broader range of shapes and parts to make one mold. This results in faster and more efficient production. The die casting machinery and dies may be considered costly, but the die casting process is economical if a high volume of products is made.

The equipment is used for a variety of purposes. The small and controlled flame produced at the end of the torch produces enough heat to melt hard metals, such as steel, iron aluminum, copper and tin. Gas torches are primarily used for industrial metal-cutting, brazing, soldering, welding, melting, plumbing, camping and sweating. These tools have several other applications. They are used in construction sites and workshops. These tools are also used for melting ice and snow. They are used for caramelizing sugars in baked and cooked foods, such as cakes and desserts. They are used in heating and shrinking jewelery, carrying out dental work, automotive operations and bending copper tube and glass. These equipment mainly uses two types of gas fuels, propane gas and MAPP. Propane gas is relatively cheaper than MAPP gas. Propane produces adequate heat for basic plumbing and repair purposes. Propane torches are ideal for basic plumbing and repair jobs. These torches are also used by bakers and chefs to caramelize sugars while preparing desserts and other sweet dishes. MAPP or methylacetylene-propadiene propane gas is capable of producing a higher temperature as compared to propane. It can produce a flame of 5300 degree Fahrenheit. It can speed up repair and plumbing jobs. MAPP torch is ideal for repairing larger pipes with excess water. MAPP gas boils out water at a much faster rate. MAPP torches are also widely used for underwater metal-cutting. MAPP torches are not a good choice for steel welding. It is ideal for welding of copper and aluminum. Gas torches are available in a variety of sizes, including large torches with propane tanks and small hand-held devices. These gas equipment are easily available in hardware stores and DIY shops. It is preferable to choose a torch depending on its purpose. Gas fuel torches produce a very high degree of heat. These equipment can be very dangerous, if not handled carefully. It is advisable to follow the required safety procedures in order to avoid fatal accidents. Extreme care should be taken while lighting a gas torch. These gas fuel torches should be used only with correct equipment. Check all the equipment, such as the fuel source, torch, piping and connections, before you start. Further, it is advisable to wear protective clothing, helmet, mask and gloves to avoid injuries. Make sure first aid and fire extinguishing equipment are kept in the vicinity. Also, make sure that no flammable or combustible liquids are kept in the surroundings. Article Source: http://EzineArticles.com/6762243 This is an article that might help you in your casting hobbies.

A bronze casting demonstration held May 2008 at Glendarragh Studios, Co. Wicklow, Ireland. http://www.umha-aois.com "Umha Aois" (Irish for "Bronze Age") is an ongoing experimental project organised on a volunteer basis by a committee formed of artists & archaeologists. Through research and experimentation we are attempting to rediscover our Bronze Age ancestors' casting methods, and in the process empower the artists involved with unique approaches to working in bronze. This video demonstrates our discovered techniques to date, using bellows to power a small charcoal fired furnace, melting bronze in a hand made crucible, and casting into a clay mould. The mould is broken open afterwards to reveal a typical Irish Bronze Age axehead. Please note that although we are striving for "authenticity", some aspects are still in development, such as the lifting tongs, forged by Umha Aois member Mary Jane Verniere. Also we have not allowed "authenticity" to stifle any creative ideas, and as such we do not pretend that our methods reflect any specific time period or place, but rather we strive for a reproducible approach to working small scale bronze with 'primitive' technologies, taking the Irish Bronze Age as our main inspiration. This is a great video demonstration of bronze casting using the early method of casting. It is great to see this as a part of history in metal casting.

My daughter helped and does the narrative. The addition of perlite not only extends the mixture but insulates the heat as well. This adds a great efficency to the device and saves propane. You can also make a foundry like the original by welding on a piece of chainlink fence pipe for the burner sleeve and welding a few reinforcing wires in the top to secure the refractory cement. Note that all of these types of foundrys locate the burner inlet offcenter to produce the spiral "tornado" effect of the gas as it burns. The fire proof lining is Harbison Walker KS4-plus which has stood the test of time in my first video. very durable with no sign of failure.
