Investment Casting

What is the investment management process?

For customers who need simple to complex parts made from a wide range of metals, investment mold forming processes offer unique benefits. This technique utilizes missing wax forming processes in which a partial pattern is made of wax. The wax pattern can dipped or covered with a ceramic slurry that hardens to form a mold. The wax melts from the ceramic mold while molten metal poured inside. As the metal cools, the ceramic mold removed to expose the cast metal part. investment casting manufacturers India

The investment process itself involves many important steps. But keep in mind that it really starts with the customer deciding on the dimensions and details of the part along with the type of metal that used. Once we receive this data and documents, our role in the investment process can begin.

Investment measures

Design and manufacture of tools

Tool design and manufacturing processes focus on the tools needed to create wax patterns. The tool must also be designed and manufactured for both water-soluble and ceramic cores.

Production of wax patterns

The step of forming wax patterns involves forming wax patterns that  used to make ceramic shell shapes. Injection molding and injection molding techniques used to create the patterns.

Make a ceramic mantle

The next step in the investment mold process to take a wax pattern and dip it or wrap it with ceramic slurry. The slurry has binders that can cure the ceramic while obtaining the same coating. The ceramic shells harden when the wax  removed by melting or firing.

Melting and casting

Ceramic molds can preheated. Then the process of casting with molten metal in a ceramic pattern begins. The molds are preheated to eliminate cold areas that can cause uneven cooling of the molten metal as it fills all cracks and cracked parts of the mold. When the casting is complete. The metal allow to cool while the part is ready to form.

Cutting and cleaning

The ceramic shell removed to open the casting. The part has now undergone a cleaning process in which all gates and gutters are removed using grinding, cutting and firing techniques. Secondary authorization form

Secondary processing processes help to cut and shape the casting process to suitable surface dimensions. During this phase, different CNC machines can be used depending on the complexity of the part.

Optional heat and surface treatment

Optional heat treatment and surface treatment may be required to improve the metal properties of the part. The heat treatment process usually takes place after cutting and cleaning the part, while the surface treatments take place after the second treatment process. Heat treatment can help harden and impart mechanical properties to the components, while surface treatment can improve some properties, such as corrosion or abrasion resistance. Inspection and packaging

Each finished part is inspected to ensure that only the highest quality components deliver to the customer. The parts are then packaged for shipment to the customer.

The production of the casting is explained in five steps

Components for mass metal production have many process options. While 3D printing is in vogue, high volume production is better than traditional casting. Why? Traditional start-up through the investment start-up process is economical and reliable. The modern molding process involves pouring molten metal into holes in a mold to form the desired shape. The liquid metal is then cooled and allowed to harden before being removed from the mold in solidified form. The molding process has five steps: patterning, shaping, melting and casting, tapping and heat treatment and inspection. Read on to find out more about each step.

Create a pattern

The first step in the molding process involves making a copy of the applied product that can used to shape the mold opening and provide precise dimensions and characteristics. The patterns can made of different materials such as wood, metal, plastic or plaster. The accuracy of the dimensions and design especially important here, because the pattern determines the shape that is available in the design. Accurate calculations needed to ensure that the latest cast products fit and work as intended.

Investment location

Investment molding is a specific type of mold making that uses wax patterns. When the molten metal poured into the mold and left, it will conform to the shape of the wax pattern. The high quality molded product then released and the wax cartridge can be melted down for reuse. form During pressing, the mold ready to receive the molten metal. There are two types of mold making processes: reusable and non-repeatable. As the name suggests, reusable molds can reused and are usually made of metal.


Unusable molds destroyed during the forming process. Sand formation is the most useless molding process. During grinding, the treated sand tightly wrapped around the cartridge and placed on a mat called a “bottle”. Once the cassette removed, the plaster remains.

Melting and casting

The slats can of any ferrous metal (those with iron, such as stainless steel) or non-ferrous metals (those without iron, such as aluminum and copper). Before they can used in the forming process, these metals must  melt in a furnace. The molten metal then poured into the hole in the mold and allowed to harden. Shaking and cleaning. Once the molten metal  fix, it is time for the fourth step: shaking. The mold shake to remove sand from the mold. Any excess metal remove during the cleaning process, often with a hammer or band saw. Drum drums, pressure washers. And air blasters can also used in the production of castings to clean the remaining sand and smooth out any rough edges.

Heat treatment and control

The remaining bar should be the same as the original pattern. Depending on the end use. The product may be subject to different finishes. For example, castings made for heavy industrial use often heat treated to withstand freezing temperatures, humid environments or extreme loads. The tool steel casting combines carbon and alloy steels to ensure wear and abrasion resistance.

Finally, the formation undergoes rigorous testing to check structural integrity and physical properties.

Advantages of die casting

Die casting can have significant advantages over other production processes, which often lead to significant cost savings, not only in the price of the part itself, but also in the total cost of production. When you place a part, you can create complex grids. Including outer wires and complex inner parts with small construction angles – minimizing secondary operations. You can also mix multiple components in one piece, eliminate assembly operations and reduce labor costs with the added benefits of simplified inventory control and greater component coherence.

Other advantages of this casting include:

Variable wall thickness
Stricter approval
A few steps from the raw material to the finished part
Fast times in the production cycle
Edit waste materials
Long tool life, especially for zinc and magnesium
