When choosing a stamping method in die-casting mold making, the factors that define each process are cost, time and required geometric tolerances. The 3 common types of production are assembly line, transfer and incremental. Today we mainly introduce the production in the form of assembly line:
Assembly lines are used for small batch production of parts or very large parts that do not fit into a single press. The workpiece is moved from one station to another, adding a feature at each station. Using a combination die, a single punch completes many kinds at a time operate.
The benefits of using an assembly line for die-casting mold making:
Faster production - multiple cuts can be made with multiple dies.
Positioning of blanks - Loading and repositioning of blanks is easy. It can be turned, flipped and moved effortlessly.
Complex Geometries - Generate complex geometries without special calculations or adjustments.
Handling of moulds - moulds are lighter and less expensive to handle.
Tools - Tools are smaller and more convenient.
Disadvantages of using an assembly line for die-casting mold making:
Machine Limitations – Not all presses are capable of loading combined molds.
Slow production speed - Unlike progressive die stamping, wire die machining produces one part at a time, making it slow and time consuming.
Turnaround time - Turnaround time and production volumes are very low and slow.
Cost - Machines must be maintained and controlled by one person, and multiple machines are required to complete a process that increases labor costs.
