Metal casting is the process of melting metal, pouring it into the mold and solidifying it into the desired shape in the mold. It is widely used in the production of large parts used in heavy machinery and equipment. The molds of this method are divided into disposable or permanent. The word comes from the reuse of permanent molds. Investment casting, also known as investment casting, is a manufacturing process that uses wax molds to shape disposable ceramic molds. Create a wax model with the exact shape of the object to be cast and immerse it in the ceramic material.
After the ceramic material solidifies, turn it over and heat it until the wax melts and flows out. The cured ceramic shell is used as a replaceable coating mold. The mold is filled with molten metal and then cooled. Then use the used mold to break the metal die castings.
Why is investment casting important?
Investment casting is a manufacturing method known for its ability to reproduce complex shapes and patterns with exquisite details. Lost wax casting is preferred to avoid time-consuming tasks, and large gears can be costly.
It can also be used as a medium of art and decoration. Investment casting is mainly used in industry, although small business owners and craftsmen can use other materials to produce it on a smaller scale to make art and jewelry.
This is usually used to make metal parts and machine parts.
Investment castings are used in a range of industries, including firearms, food services, oil and gas, and the energy sector. It can be found in your daily life, such as your refrigerator, car and other parts. Instead of making each model individually in a facility equipped with expensive equipment and a large number of employees, they can produce thousands of models using permanent or even one-time models.
This method is very important for its quality control. Can make a perfect wax mold, can accurately mark the details of the mold. This may not be the most economical for the environment because all molds and castings will be lost in the process. But value for money is worth it.
Simple steps, high demand and employment opportunities. This is the perfect recipe for a great way to mass produce parts and components for all major industries!
What is investment casting process?
We will explore step-by-step guidelines on how to complete the investment process. There are many steps, but this is an interesting way! Read on to learn more!
First, we create the model
Many metal casting methods require the creation of patterns, which are copies of finished objects used to create molds. These patterns can be permanent or disposable and can be wax, wood or plastic.
Then the mold is ready
According to technology, molds are made using various methods. For example, CNC machines can be used to make permanent metal molds, while sand molds are made by placing a sand mixture outside the design. Mold manufacturing is a professional technology related to mold manufacturing.
However, for lost wax casting, the mold is made of the wax representative of the final product. Wax gives it a smooth surface and exquisite details of each work. Then it is brought into the high-temperature chamber and melted, leaving only the mold and filling material.
Then we fill the mold
Heat the metal or other material until it melts and then pour or press it into the mold. For example, in investment casting, metal is melted and poured into the mold, filling every corner of the mold. Then, let it dry and cure. Once this step is completely completed, we can move on to the next part.
Now let's delete the product
The casting is removed from the mold after cooling and solidification. This means that for procedures such as sand casting, the mold must be destroyed to contact the components; For permanent molds, the two halves of the metal mold are disassembled and ready for reuse.
For sand castings, the mold can be redone with the same sand. Once dissolved, the sand can be reused. However, for investment castings, the mold is damaged in this process.
Finally, the final touch up
If the product is metal, the parts can be polished and repaired. This will give them the desired gloss and final gloss. If defects are found, the part will be discarded.
Application of metal castings
And more! It's amazing when what we don't even know becomes a thing and a part of an important and important thing in each of our lives.You may also know people who work in this industry and know that it has created a lot of jobs over the years.
Why is casting more popular than manufacturing?
Investment casting produces precision parts while reducing material waste, energy consumption and subsequent processing. It also ensures the production of very complex components. Therefore, design engineers can benefit a lot from the investment casting process.
The manufacturing process involves many online methods. This includes forging, welding and, most commonly, stamping. Manufacturing is the process of using labor, equipment, tools and biological or chemical treatment or formula to manufacture articles.
It can either refer to the large-scale transformation of raw materials into finished products, or it can refer to the manufacture of more complex objects by selling basic products to manufacturers to manufacture goods such as vehicles, aircraft or household appliances.
well. Casting is a kind of manufacturing!
The most convincing reason manufacturers use molding is that it provides incredible design freedom. This is a highly adaptable method that allows the use of complex design processes that cannot be achieved by other manufacturing methods. In addition, because it includes a relatively simple and easy production process, it allows a rapid transition from raw materials to final products.
Pouring something into the mold and releasing it is what makes it so good. Making a perfect mold has the precision of wax loss casting, which can economically reduce the production time.When using the machine to perform this process, you may encounter problems and worry about hiring special staff to deal with these problems.
The cost of a machine may exceed the cost it can produce in a short time.
Since there are no restrictions on the assembly of components or shapes, molding also allows the creation of visually pleasing patterns. In order to achieve an appropriate casting finish, a variety of casting procedures can be used. Sand casting has a rough appearance, while die casting and investment casting have a smoother appearance. Casting also helps to reduce residual stresses in the finished product.
Cost reduction is the most obvious benefit of using casting process.
Casting greatly reduces manufacturing costs because it allows the integration of multiple elements in one production. It also requires shorter manufacturing time, thereby reducing prices. In addition, design freedom and flexibility are translated into reducing processing and metal overhead.
Investment casting process is very suitable for manufacturing precision parts with less labor and cost. Very simple, it can be expanded to generate short-term profits.
