Titanium investment casting is the process of using a mold to create shaped pieces from titanium. Titanium is used in a variety of applications, although it is most famous for its use in airplanes, spaceships, and jewelry. However, many traditional commercial products have titanium or titanium alloy parts and pieces that help the products work daily.
The metal casting process has changed little in the thousands of years since its original invention. Today’s copper casting companies have invented new machines and casting materials that make the process easier and defects less likely, but in the end, the overall casting process remains the same. First, the copper is melted, then poured into a mold and allowed to harden. After the metal hardens, it is removed from the mold and polished and modified until it reaches the desired shape, texture, and brightness.
One of the parts of the investment casting process that I initially found hard to understand was the process of removing the wax patterns and runner from the ceramic shell once it hardens. If you scour the Internet’s offerings on the lost wax casting process, if you find anything at all, it might not always be clear how the whole investment casting process works, let alone how each stage in the process is executed. This can be the case with a lot of industrial processes, and as someone who regularly writes about industry, I know that this can be frustrating.
I am a terrible golfer. That’s not to say that I don’t enjoy it, but I have no illusions about my abilities as a golfer or my prospects for improvement. This past summer, after having played golf maybe a dozen times every year since late elementary school, I sank my first par. It was simultaneously exciting and embarrassing (but mostly exciting). My current set of clubs is composed mainly of stainless steel club heads and, I think, stainless shafts. They’re certainly not professional quality, but I’ve never had a legitimate reason to complain about them.
I have always imagined cold chamber die casting to look something like a scene from an old cartoon where the character is suddenly encased in an entire block of ice. I imagined the process froze the metal quickly into the shape of a mold. Of course, this is not really the case. Freezing hot metal suddenly can cause the metal serious stress and even cause breakage in the metal. Cold chamber casing does not have so much to do with adding cold temperatures to the metal as it does with carrying the melted metal from one machine to another for die casting.
The process of die casting aluminum using the cold casting method is similar to the hot casting process, but has one major difference. Rather than the metal melting in the same machine as the mold itself, the melted metal is melted in a different machine, then transferred to the die casting chamber via a cold chamber. There are both advantages and disadvantages to the cold casting process for die casting aluminum, but cold casting is usually used with aluminum due to the high melting point of the metal.
In an age of the latest and greatest in cooking technology, many chefs are making a surprising switch to one of the oldest cooking materials in the books. Cast iron pots, pans, skillets, kettles and more are often preferred to new specially formulated instruments in professional kitchens. Often more economical in the long run, durable cast iron cookware even add an extra something to every dish they help prepare. Chefs, food critics and researchers alike have long noted the benefits of this versatile material in the arenas of both health and taste. The advantages do not end at the dinner table, however, as is evidenced by the continued use of grey iron castings in the industrial sector for an ever expanding line of products.
