This is WEG – Casting and Machining


WEG is one of the world’s largest manufacturers of electric motors, but they are also more than that. They are a world class manufacturer of industrial electric equipment. WEG is built on a foundation of vertical integration that gives them the ability to control the quality of all of their products. This is the first in a series of articles highlighting some of WEG’s manufacturing process. 3663527418_a700a2bfc9WEG has several foundries on site where they make their own cast iron. By investing in new technologies WEG is able to strictly control the quality and consistency of their cast iron frames. WEG’s newest foundry is almost wholly automated, bringing some of the world’s most advanced technology to bear in the manufacturing process. The new foundry consists of a 6000kW induction power supply connected to two 8 ton Heavy Steel Shell furnaces, a 1000kW induction power supply connected to a 60/71 ton channel furnace that is used for holding molten metal. An Automated Pressure Pouring System with vision pouring controls makes casting safer and more precise. All equipment in the foundry can be controlled as one system. WEG cast iron parts are then machined with the exacting levels of precision that WEG demands of its manufacturing process and products. More than 40,000 cast iron parts are machined every day at the main WEG facilities in Jaragua do Sul in Brazil.
