What are the advantages of using moulding?
molding process has several advantages over other molding processes. The following is a short list of what you can expect from utilizing Injection Molding as your form of production.Injection molding allows for high production output rates.When producing your product you may use inserts within the mold. You may also use fillers for added strength.Close tolerances on small intricate parts is possible with Injection Molding.More than one material may be used at the same time when utilizing co-Injection Molding.There is typically very little post production work required because the parts usually have a very finished look upon ejection.All scrap may be reground to be reused, therefor there is very little waste.Full automation is possibl
Why is pig iron called pig iron?
Definition of Pig Iron: The term was derived from the method of casting the bars of iron in depressions or moulds formed in the sand floor adjacent to a furnace. These were connected to a runner (known as a sow) and when filled with metal the runner and the numerous smaller moulds were supposed to resemble a litter of suckling pigs, hence the term pig iron.pig iron is called pig iron because due to it shape and molds. When the iron come out from its mold due to it contain % of carbon and it look black pigs, when it come out of it mold it look like pigs standing in a group so it is called pig iron. answered by vsp the king
What is the difference between cast in situ and precast concrete?
Pre-cast concretes are manufactured in a pre-cast plant or on site (tilted-up construction). Cast in steel moulds with precise dimension. Very good quality control. Delivered and erected on site. Cast in-situ are constructed on site using fresh concrete from trucks and placed by workers. Quality Control is the responsibility of the site manager.
What type of engineer designs legos?
There could be numerous engineers helping to design LEGO bricks. If you're a software engineer, you might be helping to develop internal software for product designers to use, or maybe you're handy with the metal moulds used to cast the LEGO bricks, or maybe you're an expert on the manufacturing line machines. There are so many jobs in the LEGO company that an engineer can fit into many roles when it comes into creating LEGO bricks.
What is the difference between pig iron and cast iron?
Pig iron is cast iron with a very high carbon content: 4% by weight or more. Cast iron has at least 2% carbon by weight. Less than that, and it's steel. Cast iron and pig iron are not called steel, despite being iron carbides, because they lack the structural strength of steel and are extremely brittle. In terms of the microstructure, cast iron and pig iron contain no cementite, austenite, or martensite. Historically, "pig iron" refers to cast iron made by a particular process: the high-carbon molten iron made in a blast furnace was poured into moulds made of sand, which had a particular shape. Narrow trenches would run down the edge of the mould, and then branching off of them there would be the actual ingots. The whole setup looked to the ironworkers like a sow suckling piglets, so the product became known as pig iron.
Can chocolate moulds be used for anything other than moulding chocolate?
Chocolate moulds were originally invented for moulding chocolate but a creative cook or pastry chef can use the moulds for other things. For example, candy fudge other than chocolate flavour can be poured into the moulds while it is still warm and before it sets.
What has the author G E Dunton written?

Is there such thing of moulds?
Yes there is such thing of moulds. In the process of making chocolate the mixture gets poured into moulds to set and to be made into a certain shapw
Why do plain bread do not have any moulds after a few weeks?
The bread that you used is probably too fresh therefore it is not moulding. A stale piece of bread will allow for quick moulding to take place, if placed in dark, warm moist conditions (the right conditions)
What can be made from moulds?
Depends on what you want to make a mould of and what you want to cast into it. Several types are: * Moulds of figures made with lots of undercuts are often made of soft plastic or latex that can be removed from the original and subsequent copies easily. The copies can be plaster or plastic * Moulds made with the lost was method are one use only as they have to be broken off the copy. These moulds can be made of pressed sand or plaster. They are used for hot metal castings. * Moulds for blow moulding of glass or plastic bottles and products can be made of metal (for glass) or hardened plastic or metal of plastic. * Ancient sword makers would carve a mould for the rough shape of the sword in a flat rock and pour the bronze or iron into this mould. Cast Iron ornaments like fences can be produced by a similar method * Moulds for engine blocks are made of a sand/binder mixture and "frozen" into shape by te addition of a catalystic hardener * Moulds for shaped cookies can be plastic or metal * Moulds for jellied desserts can be plastic, glass or metal * Moulds for auto body parts are made of steel. They are often called "dies" * Dental moulds for teeth and similar kit moulds for moulding children's hands etc. are made of a seaweed derivative

How can you melt silicon cup cake case to re use for my own molds?
Silicon moulds are frequently used for small runs of jewellery. I had several silver castings made this way of an Eagle Claw. You could contact a silversmith, or perhaps the appropriate part of a Polytechnic. (Craft School) Major makers of silicon moulding materials, (Dow, ICI?) may be able to help.
