Foundries can be uncomfortable and dangerous places for people to be because of the hot metal, dust, noise, and fumes, but they are perfect places for robots.
Robotics may be used to automate a wide range of casting and foundry processes. Although material handling is a natural use, robotics can also be employed for ladling molten metal, processing sand cores, and die lubrication.
MATERIAL HANDING – Pouring molten metal requires a steady hand, and the right robot has the greatest degree of stability. A foundry robot skims dross and ladles metal more steadily than any person, which minimises spills while optimizing quantity.
SPRAYING – When dies are open, a lubrication coating frequently needs to be sprayed over their surfaces. This is an easy task for a robot. It simply follows the predetermined path each time and can be designed to optimize mold release by placing more material where it is required, and less where it isn’t.
FOUNDRY OPERATIONS – Although sand casting foundries differ slightly from other foundries, they have many identical jobs for robots. One instance of minimising damage is when handling sand castings. Others include core assembly and extraction, metal skimming, and pouring.
MATERIAL REMOVAL Sprue, which includes undesirable runners, risers, and flash, is a necessary component of casting and needs to be eliminated before parts are transferred to downstream processes. A foundry robot can load cast objects into a de-gating or trimming press or carry a grinding wheel or another cutter to remove this extra material.
