Case Studies
Weld lines and sink marks – just a question of visual appearance?
At the beginning, when LEWITT entered the microphone market, most of the produced parts were die-casting components. Sometimes small plastic parts were used in the assemblies. They were low in complexity, significantly small in size, but most of all hidden from the customer's view and not really challenging from an engineering and quality point of view. Whilst expanding into other product segments of the professional audio industry, the need to use larger and more complex plastic injection molded parts became a reality. As a result, the engineering team had to face new challenges, namely mastering the design and the production of such parts according to the market requirements ...

Similar and yet completely different!
In process simulations, users too often rely on extrapolated material data, or data for supposedly similar materials. Studies on fiber-reinforced plastics clearly show that such "family values" cannot replace individual measurements on the compounds. A case study from the Moldex3D database.

Drop by Drop
Plastic Innovation GmbH is taking a new approach to the economical and sustainable development of bicycle frames with carbon fiber-reinforced plastics. In the conception of functionally integrated and injection mold-ing-appropriate designs, SimpaTec supports the company with up-to-date simulation expertise. The frame of the first fully functionable demonstrator, an e-bike with a challenging low-entry design is manufactured fully automatically in a cycle time of 90 s by the WAIM method.

High Gloss – Paintless and Painless
Skillful application of the evaluation and analytical options afforded by process simulation, including designing the best temperature-control system and making comparisons with alternative manufacturing processes, smoothes the way to efficient product development and manufacturing. Doing this from the very start of a project enables investments to be weighed and qualified, and technical, economic or environmental concerns to be taken into account, as exemplified here by a part with a high-gloss surface.

Holistic virtual product development - Traditional concepts meet micromechanical approaches
The question is at which point a cycle begins. A cycle that has existed for many years in the context of virtual product development and has been customly accepted. But is this the right question? If we question this approach, new aspects consequently arise. For example, whether existing, previously proven mechanisms can or must be supplemented or extended in order to achieve set goals, perhaps even to exceed them, and if so, how?

More is less
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.

Crafty simulation – creative design
In many areas, when developing plastic components, almost every process and every mold or die is optimized in advance with the aid of simulation tools. But when it comes to thermoforming simulation is still used quite infrequently. Compared to using prototype tooling, however, software tools can save both time and money.

Gating balance in multiple cavity tools
Many plastic components are manufactured in multiple cavity tools. This goes hand in hand with the problem of unbalanced filling. In Moldex3D, not only the cavity, but also the gating system is meshed with volume elements.
