Benefits of Closed Die Forging Machine

Distinct from investment casting, initial costs of forging dies for developing a metal components in closed die forging is quite high, but by comparison, if the parts are in high volume, it is the most cost-effective metal forming methods for the low cost of each part. During closed die forging process, the pressing of workpiece between forging dies will refine the inner grain, and the mechanical properties of closed die forged parts, especially the strength, will be improved. So, when safety factor and strength is considered, like lifting & rigging hardware, closed die forging will be the unique choice. As products are deformed in high precision forging dies, so the toleraces of closed die forging parts are always tight. And surface finish is always good. Normally, we can control closed die forging parts within tolerance +/- 0.5mm. In this way,this forging technic is a net or near net shape process that requires less or no machining.
