Sink marks occurring on injection moulded parts are mostly undesired because of optical reasons. CADMOULDÆ 3D-F is able to predict sink marks and visualize associated optical deffects. Download full article...
This application sheet describes how DEFORM-3D simulations can be used to predict the formation of defects due to metal folding onto itself. Optimized processes can be develiped prior to tool manufacturing for production tryouts. Download full article...
Successfully modeling solidifi cation of Cast Iron is of great help for the foundries to reduce their production costs and thus to increase their profi ts. If the basic physical solidifi cation phenomena are correctly modeled by the simulation tools mold rise ring can really...
Editorís Note: This article discusses the recent advances made in the simulation of the hot-stamping process. A threepart article providing an overview of this growing technology appeared in the December 2006, January 2007, and February 2007 issues of STAMPING JournalÆ. The use of ultrahigh-strength steel (UHSS)...
Blanking and piercing are shearing operations. These involve elastic and plastic deformation, as well as ductile material fracture. Material is stressed between two cutting edges and fracture occurs from void initiation, growth and subsequent hole coalescence. The process takes place through the thickness of the material...
Modeling of wear in hot forging helps optimize tool life with a reduce cost, since physical trials are avoided until a satisfactory result is achived through simulation of the hot forging process. This technique allows the evaluation of several preforms and process conditions, among which...
I want it cheaper. I want it better. I want it faster, preferably yesterday. The pace of business in the metal stamping industry continues to escalate. And the trend is not going to reverse. Balancing cost against quality and time can be a real challenge. Add...
Cold Forging Innovation Project is a project to bring together Tier 1 suppliers, cold forging suppliers, material suppliers, tool suppliers, machinery suppliers and lubrication suppliers to strenghen the cold forging supply chain in Mexico. Download full article...
A study was conducted on the manufacture of a flanged shoulder bolt blank on a two die ñ three blow header. The method of manufacture is a common one that includes trap extrusion of the initial wire, a cone upset and final forming of the head without the...
