Simulation par ordinateurIndex. décimale : 668.4 Plastiques, vinyles Résumé : In the realm of virtual product development, the idea of the cycle has been around for many years. But where does the cycle begin? When we take a closer look at this concept, new aspects rightly start to emerge. For example, whether it is possible or necessary to augment or expand existing, hitherto proven mechanisms so that goals can be achieved, or perhaps even surpassed - and, if so, how this is to be accomplished.

Structures multicouchesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Making the production of optical lenses economical while maintaining a certain level of product quality poses a huge challenge. Aside from the need to modify the geometry of the molded part, there is often a debate about the right production strategy. Injection-compression molding may offer an alternative to injection molding in terms of quality, but it is also cost-intensive. This is where simulation can serve as a decision-making aid. Note de contenu : - Injection molding or injection-compression molding ?
- Simulation insights and differences
- Multi-layer injection molding shortens cycle time

Température -- ContrôleIndex. décimale : 668.4 Plastiques, vinyles Résumé : Short product lifecycles and high demands on injection molded parts require efficient product development methods. Besides new process management strategies, simulation is an important component at an early stage of product and mold development. This article validates the simulation of the water-assisted injection molding technique, compares two fluid-assisted injection molding techniques (FAIM) and presents a typical practical application.
