A Guide to the Manufacture and Uses of Hongtuo metal castings
If you are unfamiliar with Hongtuo metal casting, then you are not alone, however, it is basically a process where metal is heated at high temperatures until it melts. This liquid metal is then poured into a mould or cast, allowed to cool down, so that it takes on the form of the mould or cast that it was poured into. Once it has been fully cooled, the cast is removed, and the finish item is then checked for imperfections, polished and is ready to be sent to wherever it is needed.
The Benefits of Castings
Components made this way are better suited to aspects of manufacturing where specialist parts are needed, and where machine welding would cost too much. Aside from the cost benefits, another advantage to Hongtuo metal casting is that it is easy to reproduce identical parts, quickly and easily. This means that replacement parts can be made to order as well as making it a lot easier for the design to be tweaked and changed.
The Mould or Cast
The cast or mould is one of the most important parts of the whole Hongtuo metal casting process, as this is the shape of the finish product. The moulds or casts are often made in a foundry, and companies will often send their design requirements to the foundry in order for them to begin the process of making the mould.
Difficulties that can arise during the Process
The Hongtuo metal castings process is not the simplest manufacturing procedure, and it is possible for a number of problems to arise during the procedure. For example, if any outside pollutants or impurities make their way into the metal when it is in its liquid state, then there is a chance that when the metal solidifies it will contain imperfections and weak spots. Air bubbles are another problem that can arise during the casting process, and this can lead to a weakening of the metal.
There are many uses for Hongtuo metal castings, even now in the 21st century, and some of the most important parts for vehicles are still made using this method. Powertrain components such as pinion housings, differential cases and brake callipers are all made using a Hongtuo industry casting technique, and these parts are used in commercial vehicles, farming vehicles, trains, plant machinery, and even offshore wind farms.
