What is Precession Inox Lost Wax Casting and 3D Modeling?2020-10-03
Inox lost wax casting introduction
High-precision inox lost wax casting is actively used in metallurgy. The method has established itself as one of the most effective ways to create parts of complex shapes.
Generally, investment casting allows you to obtain castings that do not require machining.
Precision casting is used for all types of ferrous and non-ferrous metals. Therefore, to create a mold, a patented mixture of low-melting materials is used.
Inox lost wax casting manufacturing process
The production of inox lost wax casting is a complex technological operation. Therefore, high quality of the final product is possible only with full compliance. Moreover, it comes with the requirements for the manufacture of parts from steel billets.
The order of operations for preparing forms:
- preparation of molds
- model composition pressing
- holding the composition until hardening
Basically, shell metal is poured from ladles. The mixture temperature reaches 900-950 degrees Celsius. Furthermore, temperature control during casting is provided by an automatic metal casting system.
The resulting alloy is processed on special machines.
Inox lost wax casting dimensions
Inox lost wax casting are of 5-8 grade of accuracy. The dimensions of the cast element are as close as possible to the parameters of the part. Similarly, it simplifies its mechanical grinding. Often, the manufacturing precision is so high that no machining is required at all.
Casting from the Essaii is widely demanded in everyday life. A number of companies across the world are using casting products. The company's products are used in:
- mining and
- other industries
There is currently no industry in the world where precision cast stainless steel parts are not used. The basics of high-precision casting technology using wax models have been known for a long time. And craftsmen of ancient Babylon 4 thousand years ago have been using it.
In China, Inox lost wax casting from stainless steels was widely used in the 1940s for the manufacture of aircraft engine blades. However, new requirements arise. And modern casting technologies become unique. Currently, China and world manufacturers keep their lost wax casting technologies in know-how mode.
What is precession Inox lost wax casting and 3D Modeling?
The modern precession Inox lost wax casting process begins with the transfer of a 3D model of a future part. Commonly, a 3D model can detect errors at early stage. The cad system optimizes design very well so one can check the future mistakes. Furthermore, this process is quite quick and low cost.
For example, it is effective for reducing the weight of the part. Moreover, it is important to assess the possible risks of obtaining defects. Therefore, we can change he possible results by seeing the faults. s Hence, it allows reducing the technological defects.
Application of modern CAD systems in low wax casting model
At the next stage, the base mold is designed and manufactured. It forms the wax models of the future part. The mold is a technically complex. Furthermore, it is responsible device. It requires high-precision modern 3D printers for mechanical purposes.
The quality of the future part made by Inox lost wax casting depends on the quality of mold manufacturing. Similarly, it also depends on the materials and design too. The service life of the mold is from 10,000 to 50,000 models. After it the mold is not used.
Precision Inox lost wax casting: The mold is a complex critical product
Before being fed into the mold, the wax mixture is prepared. The wax is heated and melted in a special machine to a liquid state. Subsequently, it is mixed with a mixture already in use from previous wax parts.
The heated wax composition is pumped into a settling tank. This process is important to check for mechanical impurities. The finished wax mixture is filled into molds. So, it forms a lost wax model. Molds filled with a wax mixture cool down gradually.
After the wax mixture has hardened, it is removed from the mold. A thorough cleaning in Inox lost wax casting process is vital. Cleaning is carried out on a conveyor-type basis. It goes through wax models in a washing mixture. After that, the models are blown with an air stream to eliminate moisture.
Inox lost wax casting Initial quality control is carried out manually. A specialist examines the wax model for damage and removes excess material. The finished wax-ups are left in a dedicated room for final drying until use. Often wax models are made just before the order is fulfilled in the required quantity.So as not to create additional storage space / inventory.
How to get ceramic shape in wax casting process?
The ceramic shape ensures a smooth surface of the parts. The prepared wax model of the part is covered in several cycles with special refractory mixtures. Hence it ranges from fine ceramic to sand.
At the end of the formation of the ceramic mold, it is heated: the wax model is smelted using a steam oven. The melted wax flows out and is subsequently used in the recirculation of the wax. There remains a ceramic mold, a chill mold, ready for casting from stainless steel.
Before casting the product, the ceramic molds are heated to the appropriate temperature. In addition, this prevents the molds from splitting when in contact with the molten metal during pouring. After pouring, the metal solidifies.
How to remove ceramic mold from wax casting?
Generally, the ceramic mold is removed using a special vibration-shock machine. Unnecessary sprues are / removed. The sprue exit points are carefully ground. Heat treatment is carried out if necessary. Moreover, details are brought to the relevant requirements of the Customer.
Hence, the result of a series of such complex Inox lost wax casting is a high-quality part. It meets modern requirements for assembly units. First of all, this refers to the repeatability of properties and dimensions of parts.
