Lost Wax Casting

Lost wax casting process can also be referred to as investment casting in the casting sectors as professional terms. Lost wax casting kit is the critical tools to the lost wax casting processes, such as lost wax bronze casting, lost wax ductile casting, etc. Lost wax casting is recognized as one of the oldest metal casting method in the industry which belongs to the process that is based on lost wax investment casting method.

About four thousands of years, lost wax castings and precision investment casting processes were used to form precision molds all over the world industrial sectors for different kinds of works. According to the historical record, the first form archeologist has found so far was based on the beeswax for the formation of patterns. The pattern formed is for the purpose of casting processes. Though this was the old way, it is still very accurate and convenient to do for modern workers.


How Lost Wax Casting is Used Today?

The great productivity and wide industrial usages are the main advantages of the lost wax casting. This casting process is still used by many industrial users now. This method can bring the optimal work piece components with great repeatability level, accuracy rates, and versatile flexibility ratios. The integrated benefits of this method make investment casting process popular so far in the metal working industry for high performance alloy materials’ processing.

For modern industry, there are mainly four benefits commonly recognized in the processing of lost wax casting. These four benefits are assembly process reduction, flexible design, cost down benefit, and detail casting capacity. First of all, for assembly process reduction, the investment casting process can do a lot as several components can be made as one casting object, which reduce the costs of handling, inspection, assembly, and other procedures. For the point of flexible design, the investment castings are able to manufacture precision details with great dimensional accuracy that is hard to be achieved by other casting methods under the same budget. Thirdly, the point is about money. For cost down benefits, business owners using this method can save a lot of resources such as energy, money, and processing steps. So it is widely recognized that investment castings are the optimum casting methods in the casting sector.

Lastly, for detail casting capacity, it is very convenient for users since the investment castings can cast objects with fine details such as holes, bosses, splines, lettering, threads, etc. This feature is hardly seen on other casting methods as all other alternative methods with the same budget level can hardly achieve this result. 


Lost Wax Iron Casting & Lost Wax Bronze Casting

Like the case that bronze casting can be referred to as casting of bronze, iron casting can also be referred to as cast iron. Together with the lost wax casting method, these two elements are the most ancient cast metal packages in the human civilization history that drove the humanity towards progressions in technology. Lost wax casting of iron is a metalworking process that produces a group of iron based work pieces. Iron-carbon alloys with carbon content greater than 2% is a conventional iron casting products. The usefulness of iron casting derives from its relatively low melting temperature. The alloy constituents affect its color when fractured as well as the mineral casting. Fractures with different colors indicate different conditions and the mutations, and onsite operators are requested to know how to deal with those conditions on time. 


Lost Wax Mineral Casting

Lost wax method can also be applied to mineral casting. Mineral casting conducted by the lost wax casting process is also considered polymer-bonded mineral casting, which is a construction and design material with enormous potential. During the operation of casting, selected minerals and a low proportion of epoxy resin-based binding agent form the basis for a high performance casting materials for a wide range of technical and artistic applications. Different from iron and bronze casting, this is a metalworking process that produces a group of iron-carbon alloys with carbon content greater than a certain level of percentage. The alloy constituents affect its color when fractured, that is, white cast iron has a carbide impurity which permits cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack, and this will initiate countless new cracks once if the material breaks. The influence of this phenomenon is obvious and operators have to come up with the instant dealing methods. 


Lost Wax Ductile Casting

Ductile castings are often recognized to be ductile iron investment casting applications. Normally, ductile iron is also called as ductile cast iron, which is a type of graphite rich cast iron product which was discovered in the days of year 1940s. Regarding the tension issues, while most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance value. This is thanks to its nodular graphite inclusions make the best usages. Different from traditional iron casting, ductile casting is a metalworking process that produces a group of iron-carbon alloys with carbon content greater than a certain level of percentage.

The value derives from its relatively low melting temperature. Ductile casting technology is widely applied in the industry worldwide and many of the industrial insiders recognize this as the ideal way to form the cast of their ideal items. This means that ductile iron is not a single material, but rather, it is a part of a group of materials which can be produced with a wide range of properties via the control of their microstructure frame. Lost wax casting can be applied to various mineral materials and make the usages feasible to even ordinary workers rather than highly experienced experts.
