Have you ever wondered how they make those metal toys or components that we see every day? It’s pretty interesting! One popular process for producing these metal items is called sand casting. So, what is sand casting? This process involves creating a mold from sand and the special shape that has to be cast called pattern. Once the mold is ready, it pours in liquid metal to make the final product. The sand is very useful as it helps in proper molding the metal, and then after that when we pour out the molten hot bronze into this mould, on cooling of the same with time becomes hardens and can disassemble all sides/moulds. What a great way to get the metal part out of that wet sand!!!
An alternative technique to produce metal parts is die casting. Die Casting Dies castings work by extremely for high melting temperature metals liquid metal is pressed in to the mold. This means the mold fills with metal very well. And a great thing about die casting is that it allows parts to have tight tolerance shape and size wise, so the final part looks just how we designed. On the other hand, die casting is often more costly than alternatives for metal parts fabrication. Moreover, making changes to the design is not as simple once you have gotten it cast in mold - disadvantage if ever intended too for a later follow-up tweak.
A sand cast needs to be done right otherwise the product in your hand will not have any resemblance of what you intended it at most and even if its anything close, characterizing details like size may differ completely. To begin with, you place a pattern of the object which corresponds to what you want to construct into a container then fill it up with sand. You then gently pull the template from sand. This creates a void or cavity in the sand which is identical to the pattern shape. Then you pour the liquid metal in this cavity. From there, the metal cools and hardens, ready for you to remove that moulding sand with model finished. Green sand and oil sands are some of the various types of available sands for this process. That comes down to what you want the end result look and feel like.
It is not a newly established process as die casting has been in existence for some time now; however, it just got even better and efficient. Centuries ago this work had to be done by hand and today computers make the molds, which take great skill in designing them. It makes the die casting process faster and more precise than it was ever before. Other new thermo-mechanically capable materials and superalloys are also being developed that can withstand higher temperatures/pressures. It means that die casting is becoming more practical due to its many possible applications with different kinds of metal parts, making it useful in numerous industries.
Which is best way to manufacture- Sand Casting or Die Casting? The answer to this question will depend entirely on what you are trying to build and how much money is in your pocket. Both are generally forgiving in terms of revisions and tweaks to the design as well sand casting tends to be more cost-effective than die casting. One con is that it may create a less precise product in the end. Die casting, on the other hand, often delivers impressive levels of accuracy and detail— but it can be more costly to change the design once locked in. Ultimately, you want to narrow down the best way for your project.
