Comparative Study of Conventional and Quick Die Change Stamping Process: The Issue of Setup Time and Storage

Abstract

Metal stamping industry has Quick Die Change (QDC) as a form of Single Minutes Exchange of Dies (SMED) as an efficient production technique where the implementation depends on operator’s activities, clamping system, accessories type and position, etc. This QDC could apply to improve the process efficiency, control of inventory and reducing the cost. This research compared the traditional metal stamping process and QDC System (QDCS) of metal stamping. This research was using Focused Group Discussion (FGD), direct observation and experiments, conducted in a private metal stamping company in wider Jakarta region of Indonesia. It was observed that the QDCS significantly reduces setup time, storage space and the cost. The setup time and cost reduced to one third of the conventional and the requirement of storage decreased by 70%. In addition, QDCS reduces the waste significantly.

Mechanical Movement in Stamping Die Design Based on Computer Analysis

“…The variable time slice Δλ may have the following relationship with the basic time slice Δδ, as shown in Equation (2).…”

“…With the rapid development of the manufacturing industry and the fierce market competition, people in today's society have higher and higher requirements for the accuracy and efficiency of stamping parts [1]. The manual feeding method in the traditional stamping process not only has potential safety hazards, but also has low efficiency, which cannot meet the production needs of the current manufacturing industry [2][3]. Improve the automation of the stamping production line and improve work efficiency.…”
