Application of sequence control injection in modified design of car front bumper

Abstract

In view of lightweight and cost reduction, a bumper has been redesigned, which results in weld lines during the manufacture. For that, a new method of sequence control technology is introduced. The simulation results with the new method and the traditional method were compared. The results showed that the weld lines were removed, and at the same time, the injection balance was better and the injection pressure was decreased by using the sequence control technology. The sequence control technology is of great practical significance to bumper manufacturing. © Published under licence by IOP Publishing Ltd.
