Purpose: Lateral extrusion process with a lost core for cross fittings is suggested. At first, cavity of tube is filled up by low temperature melting alloy. Then low temperature melting material is solidified to be the "lost core". The third, the material is extruded for lateral direction to be a cross-fittings. After deformation, low temperature melting alloy is melted and removed. The...
Purpose: The authors discuss deform mechanism of lateral extrusion process with a lost core for cross fittings. Outline of the is as follows: At first, cavity of pipe, or channel material, is filled up by liquid of low temperaturę melting material, for instances, low temperature melting alloy, ice (or water) and wax. Then low temperature melting material is solidified to be a soluble core of pipe...
