What is the accuracy of the investment casting process for steel?
There are two main controlling factors in this process When an investment casting sets it generally shrinks upto a few millimetres from its cast size. Depending on the complexity of the component being made more advanced machinery or more skilled die makers may be required to produce the required shape. In a premium casting upto 1/8 of a millimetre is attainable- to achieve this however there will high set up costs due to the following items. When designing the die to accomodate for post-cast shrinkage the number and complexity of calculations and simulations will be large. The cost and machining time for the die cutting, and the cost of the materials involved will be much higher. The die will require a long post-process, both before production commences and between batches to maintain die consistency and quality. For a commercial standard casting this tolerance will be around +/- 0.5mm depending on the complexity of shape. On the lowest budget this can grow to as high as +/- 2mm. All the above applies for castings <0.5kg.
What is meant by two mold casting?
There are two molds that you put together to make the casting, so the part is easier to get out of the mold ----------------- If two or more (sets) of molds were necessary to produce the casting. Picture a statue, one mold was used to create the body and a second mold was used to create an outstretched arm, that is attacted separately.
Why is AC used?
The power source is AC. Hence AC is used. DC application is limited.
Is solar heating of water more cost effective than electricalof water?
Solar water heating is generally more cost effective than an electrical water heater. Though solar water heaters usually have a higher initial investment if commercially purchased.
Are there more deadtime stories episodes on nickelodeon?
There will be ATLEAST 25 more episodes, they are in the process of casting and filmin then. ~A Friend
Where can one find information about lost wax casting?
Information about lost wax casting can be found on the wikipedia free encyclopedia website labeled as lost-wax casting. The process is more commonly known as investment casting in its modern version.
Would you make them protrude from the surface or recess them into the surface on sand casting?
For sand casting, it is more common to recess features into the surface rather than have them protrude. This is because recessed features are easier to achieve and maintain during the casting process, while protruding features may be less precise due to the nature of sand casting.
What is jewelry casting?
involves pouring molten metal into a mold. This process lends itself more readily to mass production of the jewelry
Does the casting go into the well water?
No, the casting process for well drilling does not involve casting materials into the well water. The casting, which is a protective structure made of metal or PVC, is installed around the well casing to prevent contamination from surface water and to provide structural support.
Where can one find more information on casting aluminum?
There are many places where one can find more information on casting aluminium. A good place is the website "kineticdiecasting" to find more information on casting caluminium.
If the freezer plug pops out will the engine still be good?
The frost plugs are not frost plugs. They are actually openings to allow the release of the casting sand from the casting process I have seen engines survive a freeze up like this but have seen many more that did not.
What is Serial casting?
Serial casting-- A series of casts designed to gradually move a limb into a more functional position.
Where are the open casting calls for JONAS?
The Casting is over...because they finished filming season one but when season 2 starts casting you can go to disneys studios and ask for more information of where the casting would be and etc... Hope that helped
What the process called when you melt metel down and skim?
The process of melting metal and removing impurities by skimming off the top layer is called "skimming." This is commonly done in metal casting to ensure a cleaner, more refined final product.
How did the presidential election process begin to change in the early 1800's?
the popular vote become more important.
What casting process allows the use of chills?
The casting process that allows the use of chills is known as sand casting. In this method, chills are placed within the sand mold to absorb heat from the molten metal, promoting solidification in specific areas and reducing the risk of defects like shrinkage or porosity. This technique enhances the mechanical properties of the final cast product by ensuring a more uniform cooling rate. Chills can be made from various materials, including metal or ceramic, and are strategically positioned based on the design of the part being cast.
