Investment casting Robotic Shell System, for Industries

Listing ID #4263924

The Robotic Shelling System - The automated and robotised

shell production solution for an Investment-Casting foundry.

Shelling is done by dipping the wax assemblies in a series of

ceramic slurries and coating them in refractory sands.

It is critical that this process is fully automated using a robotic

shelling system; any inconsistencies in the shell thickness and

porosity, that arises from uneven sanding or draining of the

ceramic slurries, or improper drying process can cause trouble

later in the process. Resulting in defects in the castings and

hence rejections.

Doing all these processes manually simply does not give the

precision or repeatability to perform this task in a satisfactory

manner.

RoSS is a comprehensive shell room solution, which aims to

completely replace human effort to more a efficient and reliable

robotic system. 

To produce complete shell from first coat to seal coat –

ready for de-waxing.

• Shell building is performed as per dip sequence selected.

• Maintaining drying time between coats as per instructions.

• Intelligent prioritising of conveyor sequence to ensure

minimum robot idle time.

• System controlled slurry and sand levels.

• System includes: 7 machines, 6 conveyors, 6 fans, robot and

track.

• As low as 2 persons are required to operate the entire

Shell Room.

• When compared to manual dipping, output per shell may be

increased by upto 30% by increasing shell size,

• Upto 15% saving in shell materials due to reduction in wastage and optimised shelling.
