Sand casting and lost wax casting are two application areas of the current manufacturing process and a wide range of sculpture casting methods.
The sand casting method uses clay bonded sand as a modeling material to produce castings. Since it was applied thousands of years ago, most countries in the world, including the United States and Japan, are using the sand casting method to produce crafts. Sanding is a method of producing a product by pouring molten metal into a cavity of a mold and cooling it. The sand type raw material is mainly sand, and is mixed with binder, water, etc., so the sand casting method is simple and easy to operate, the material production cost is low, and it can be applied to the production of copper, plastic and other handicrafts, and is also more than the lost wax casting. The cost and manpower consumed are small. However, although the sand casting process is simple, there are many factors that change the processing of old sand, new sand and auxiliary materials. If any of the links are monitored, there is no guarantee that a certain key performance is within the control range. There may be problems. In addition, sand casting is more suitable for the manufacture of blanks, because its production process determines that this manufacturing method cannot be perfect in detail.
The lost wax method and the Tao Fan method are called the two bronze craft manufacturing methods. They are specialized precision casting methods for metal materials such as bronze. The principle of the wax is derived from the incineration method, which was first and foremost in the middle and late Shang Dynasty. The method is: using beeswax to make the model of the casting, and then filling the core with the other refractory material and applying it to the external fan. After heating and baking, the wax film is completely melted and lost, so that the whole casting model becomes empty and then watered inward. The melt is cast into an object. It is one of the three major casting techniques in ancient China. The materials are made of lime triple soil and carbon powder, which are easy to obtain. With the development of science and technology, it was gradually replaced by zircon, zircon sand and mullite.
China's bronze culture has a long history, and it has been around 4,500 years since its formation. The prosperous Bronze Age (Xiazhi Warring States) lasted for 1600 years. Cast bronze sculptures range from ceremonial to daily necessities, and many types of crafts have been produced in the late beauty of bronze. The patterns and shapes of bronze crafts in each era are different, and the details are amazing. The lost wax casting rule is a casting method that perfectly presents the beauty of the details of the bronze. Most of China's ancient tripods, furnaces, music bells, and neems were made by the lost wax method. Intersected in the sanding method, the lost wax method does not require the mold to be taken out of the sand type, so that it is possible to cast a handicraft with a very complicated shape, fine and beautiful shape. For crafts, unique details and fine grinding are essential. A good bronze crafts, naturally pay attention to the perfection of each detail and the fineness of the objects, so that it can be more ornamental and collectible. The fly in the ointment is that the lost wax process is complicated and consumes a lot of craftsman energy. However, a perfect handicraft must be more hard work and luck, which is the value of crafts.
