Investment Casting Leans on Robotization for Future Growth

Collaborative Post

Investment casting (sometimes referred to as lost wax casting) is a very old industrial method. It’s utilized in a variety of sectors to make precise parts, especially in companies that make parts with complex geometries. This article provides an explanation of the procedure, as well as various examples of where robotic automation solutions have been used, as well as the names and contact information for the robotic automation solution providers.

How Robotics are Used in Investment Casting Processes

The patterns can be transferred to different facility areas using robotic arms and conveyor belts with minimal human intervention. This method reduces the chances of the pattern being damaged when being transferred. The robotic arms also aid in the creation of more moulds per minute, lowering lead times for large manufacturing runs.

Wax pattern assembling is another robotics-based procedure used in investment casting. Some wax trees have a lot of different parts. To make the pattern assembly, these parts are attached to the rest of the sprue. This time-consuming job is carried out by robotic arms around the clock, ensuring that all pattern elements are joined in a consistent manner.

Robotic arms dip the wax design into the ceramic slurry, which often requires numerous layers, in the shell-making process. The use of robots in the process improves quality uniformity and worker safety. The robotic arms also ensure that each wax pattern is evenly coated on all surfaces.

Other procedures may also benefit from robotics. Robots may be utilised throughout the cleaning and cutting of the metal component, as well as the secondary machining process, after it has been manufactured. Robotics may be used in laboratory testing operations to perform measurements and determine part accuracy.

Benefits of Robotics in Investment Casting

Boost Productivity

Robots can work at any time of day. They don’t need breaks, and their production doesn’t suffer as a result of the long hours. This benefit aids producers in increasing production and decreasing lead times.


Based on the data provided, robotic arms are programmed to do specified jobs. Even at high production numbers, this procedure assures that every component produced has the same precise dimensions and quality.


Robots are unable to deviate from their pre-programmed parameters. Even with the robots running 24 hours a day, seven days a week, parts and components maintain their uniformity.

Role of CIREX in producing castings

CIREX uses the lost-wax method to create precision castings. These are the highest quality steel castings on the market, with low surface roughness values and accurate tolerances. They are frequently utilised for components that must work in adverse settings, such as extreme temperature changes or when the components must be extremely hard, strong, or light. Special alloys are frequently employed in these castings to achieve these stringent requirements.

Tolerances and dimensions

Castings made with the lost wax process have already attained significant dimensional accuracy. The demand for exceedingly accurate measurements frequently raises the casting’s final price unnecessarily. The company’s goal is to develop the best possible proportions so that the casting process is used as efficiently as possible.

Tolerances for “lost wax” castings are based on the VDG P690 international standard. CIREX’s standard castings are classified as D1.

Tolerances in class D1 are standard.

Exact tolerances are classified as Class D2.

Class D3: Extremely tight tolerances are only available on a limited number of surfaces.

The entire production process is entirely automated, ensuring consistent quality, reducing serial production time, and allowing you to achieve higher dimensional precision than international standards require.

To sum up,

Many redundant and sophisticated functions are included in investment casting processes. Customers can gain a variety of benefits by using robotics to execute these tasks.
