In mold design, as in bulk production, it is beneficial if you can produce as many parts as possible in a single shot.
For mold design, it is also very important to be able to eject the plastic product quickly and to be ready for the next shot without wasting movements.
Rods, an air blast, or a plate are typically used for the ejection stage of injection molding.
Every second in the injection molding process translates into money, so it is critical to minimize the mechanisms of molding to as few and as fast as possible. A design and engineering firm that is familiar with the nuances of injection molding will create parts that will lend themselves to optimized mold design.
