The Electrical Upsetting (Metal Gathering) Process
We believe that getting the perfect bulb shape is pure science and not an art. In the Electrical Upsetting process, a high density electric current at very low voltage is made to pass through a portion of bar stock, which is held against an anvil and clamped between two jaws to generate sufficient heat to make the portion red hot and plastic. An upsetting force is applied axially on the rod against the anvil, making the portion which is in plastic stage, to deform into a bulb shape and to gather the required volume.
Key Unique Features
Our Electrical Upsetting (Meta Gathering) Machines
ETA follows an Engineered-To-Order(ETO) process in most of the cases as building a product starts with understanding customer requirements. For a very limited off-the-shelf models, we have a Make-to-Order (MTO) approach though. Below is a sampling of machines that we have built for our customers under the Electrical Upsetting (Metal Gathering) category.
