When to Use Investment Casting

Lost wax investment casting, commonly known as investment castings, produces a variety of metal components with exceptional as-cast surface quality and precise detail. These are shaped into interior or exterior features, thin walls, and internal passageways to achieve a near-net shape. Compared to conventional metal casting methods, these properties generally result in significant material, labor, and machining cost savings.

Uses of Investment Casting


Experts use investment castings when there are external shaping and stringent tolerances. Likewise, it is also used when the parts are shaped or non-symmetrical with an exquisite detail.

Tolerance impacts product design, manufacturing, and quality control, making them crucial to the ultimate product’s success. As a result, setting tolerances and the amount of allowable variation in cut components is an essential aspect of the quality cost.

The goal is to balance lowering costs excessively and imposing too many regulations. Inspections, specialized equipment, higher scrap, and lower yields can all be increased by a tighter tolerance than is required.

Sand Casting

Investment casting is also resorted to when the wall thickness is too thin for sand casting. Sand casting molds are made by compacting sand around a pattern or model of the final product. It is usually mixed with clay as a bonding agent and saturated with water.

The design is taken from the mold once it has been torn apart. The mold’s two pieces are reassembled, and the void is filled with molten metal. It is then opened, the sand is removed, and the item is removed once the metal has cooled sufficiently.

Types of Investment Casting 

Though investment casting, also known as lost wax casting, has been around for thousands of years, there have been improvements to the method. The modifications are intended to improve the pattern development procedure and address the use of wax. Evaporative pattern casting is the general term for lost wax casting because the material used to produce the pattern is removed or evaporates.

What Are the Different Kinds?

Casting in Foam

Engineers can use it to produce three-dimensional renditions of their conceptualizations. It is a manufacturing process used to make decorative, elaborate, and intricate metal shapes, arrangements, and designs.

Investment Casting in Water Glass

Instead of ethyl silicate, the water glass is employed as the shell’s binding agent. The technique, which dates back to the 1950s, has a material cost and manufacturing cycle advantages. It has a simpler technique, operation, and parameters that may be accomplished by ordinary personnel, resulting in increased production and efficiency.

Casting with Direct Investment

The first approach involves carving the pattern by hand or machine to generate a one-up version that is then treated using the lost wax method. This method is used to make a prototype, produce small batches of final products, or determine dimensions.

Sand Casting

Sand casting is used to make huge pieces by pouring molten metal into a mold hole that has been formed out of natural or synthetic sand. The cavity is constructed by using a pattern, which is usually made of wood or metal and is the same shape and size as the actual item. The cavity is somewhat larger as a result of the pattern being slightly oversize, which compensates for the contraction of molten metal during cooling.

Procedure of Investment Casting

Investment castings are one of the most common metal casting techniques today. Equipment and methodological advancements have kept up with demand throughout the years. The wax is melted out of the mold by heating it in an oven, leaving a ceramic shell mold for casting. 


 What Is the Mechanism?

 Construction of a Metal Die

The master die’s size must be carefully determined, taking into account the wax pattern’s predicted shrinkage, the ceramic material invested over the wax pattern’s expected shrinkage, and the metal casting’s expected shrinkage. 

 Production of Wax Patterns

The mold or die is inserted with hot wax and allowed to set. Any internal characteristics may necessitate the use of cores. The wax pattern is an exact reproduction of the part that will be manufactured.  

 Making a Mold

 The thickness of the ceramic shell is determined by the size and weight of the item being cast, as well as the metal pouring temperature. The solidified ceramic mold is flipped over and baked in an oven until the wax melts and drains away. As a result, a hollow ceramic shell is created. 


 Liquid metal pours into the pouring cup, via the central gating system, and into each mold cavity on the tree while the molten metal is still hot. The metal flows freely through thin, precise areas thanks to the pre-heated mold. The mold and casting will cool and shrink together, resulting in a casting with increased dimensional accuracy. 


The metal cools and solidifies after it is placed into the mold. The length of time it takes for a mold to solidify depends on the material used and the thickness of the casting. 


The ceramic molds break down and the casting can be removed once it has solidified. Manual or water jets are commonly used to break up the ceramic mold. Individual castings are detached from their gating system tree after being removed by human impact, sawing, cutting, burning, or liquid nitrogen cold breaking. 


To smooth the part at the gates and remove defects, finishing processes such as grinding or sandblasting are typically used. Heat treatment may be used to harden the final product, depending on the metal from which the casting was made.

Reasons to Use Sand Castings

Flexible Mold

The mold boxes made up of sand casting are extremely reliable and easy to make.  The sand mold can hold the metal’s shape as the metal cools down to reveal the desired cast design. The use of sand casting allows you to create highly complex shapes in almost any size and form from nearly every type of engineering alloy.   

Cost-Effective and Relatively Cheap

One reason why most metal castings around the world are manufactured using sand casting is that it is relatively cheap and cost-effective. Sand casting is one of the few available processes for metals that can be recycled because of its reusability. Its ability to mold sand to be reused is a great asset in manufacturing operations.  

Strong and Resilient

Sand casting molds provide the best outcome possible because it can withstand the high temperatures of liquid metal it holds when creating designs. It can also manage thermal contraction, metal flow, and gas venting to prevent defects and impurities during the process. By using high-quality sand in creating the mold, your project will not melt, burn, or crack as molten metal is poured into it.

Cast Iron vs. Cast Steel: The Advantages and Disadvantages

Castings investment is one of the most popular methods for producing long-lasting and high-quality components. Because casting allows for a high level of detail, no extra manufacturing or assembly is required. While a variety of materials can be cast, steel and iron are the most used due to their outstanding mechanical qualities in a wide range of applications.

Castings Investment components

Differences Between Cast Iron and Cast Steel


Cast iron is a reasonably simple material to work with because it pours smoothly and does not shrink nearly as much as steel. Cast iron is a great metal for architectural or ornate ironwork structures such as fencing and street furniture because of its flowability. 

Resistance to Corrosion

When it comes to corrosion resistance, iron is superior to steel. That doesn’t rule out the possibility of corrosion in either case. Both metals will oxidize in the presence of moisture if left unprotected. They will eventually decay totally. The coating is advised for both steel and iron castings to prevent this. 


Because of the lower material prices, energy, and labor required to manufacture a final product, cast iron is frequently less expensive than cast steel. While raw steel is more expensive, prefabricated steel is also available. Sheets, rods, bars, tubes, and beams are among them.

Advantage and Disadvantage of Cast Steel

It is known that the design flexibility of cast steel is its key feature. The designer of the casting has the greatest creative freedom. Complex forms and hollow cross-section pieces are now possible. Cast steel, on the other hand, has poor shake-suction, wear resistance, and mobility. When compared to cast iron, the casting performance is poor. In addition, the costs are higher than with regular cast iron.

The Advantage and Disadvantage of Cast Iron 

Cast iron provides a number of advantages, including high wear resistance, machinability, and low notch sensitivity, to name a few. Its tensile strength and elongation, on the other hand, are extremely low. As a result, it can only make a restricted number of metal items that aren’t physically demanding.

Steel and iron castings both have advantages and disadvantages. Depending on the application and physical features, either should be employed.
