Ensuring part quality while minimizing scrap

Elastomer Parts - Finding the Optimal Runner System via Virtual DoE

Increasingly complex plastic parts, which need to meet economical as well as ecological standards, pose an enormous challenge for injection molders. Tools like the virtual DoE, featured by the Sigmasoft Virtual Molding Technology, help rising to these challenges, e.g. by finding the optimal mold design for runner systems. This can help to increase the part quality by a substantial amount while reducing scrap in early stages of the development phase.Weiterlesen...

Efficient framing of car glass windows

The assembly of plastic components is one of the most innovative applications of the injection molding process. In this case, two or more injection molding processes are sequentially strung together, either within a machine or by the combination of individual machines by means of a handling system. But the assembly by injection molding is not limited to plastic components, but also non-plastic components, such as wood, metal or glass can be assembled with plastic by injection molding. The latter is increasingly used for mounting gaskets on automobile windows. The efficiency of this assembly process is largely determined by efficient glass pane manipulation. LWB-Steinl has more than 20 years of experience and presents the options.Weiterlesen...

Coatings make sealing rings even more efficient

Anti-friction coating for first-class performance

Was Dichtungen können müssen, ist nicht hoch genug zu bewerten. Obwohl sie C-Teile sind, müssen sie A-Funktionen übernehmen. So sollen sie möglichst den ewigen Zielkonflikt zwischen hervorragender Dichtwirkung, niedrigster Reibung und geringst möglichem Verschleiß auflösen. Eine Beschichtung mit Gleitlack bringt Elastomerdichtungen allen konkurrierenden Zielen näher. Diese Nachbehandlung und Veredelung eignet sich für Großserien genauso wie für Kleinstmengen ab Losgröße 1.Weiterlesen...
