Manufacturing Basics

The Shop Floor is the place to find "how-to" topics from installing dies to the correct procedure on how to clean a plant floor. Each topic is brought to you by well-known wire and cable industry professionals.

The recommended contact point on the reduction zone of a die should be 75% to 100% of the wire diameter. The bearing (or land) of a die is downstream of the drawing cone, and although it plays no part in the prior reduction in area of the wire, it does help to preserve the wire size. A bearing surface that is too large will increase the drawing stress because of friction.

This course presents a classification of wire breaks from a perspective that compares material defects to process-related problems. Rod defects will include both casting and rolling issues such as internal voids, foreign contaminants, rolled-in scale, hot cracks, and surface porosity. The effects of wiredrawing speed and lubrication will be discussed with respect to generation of fines, shaving, galling, and other surface defects.
