How will this mold laminate in Soft Plastics Posted 11 hours ago · Report reply One thing I do when I look at a mold is visualize, think about where the plastic will go looking at the runner and cavities one one side. So for a core shot, we would pour an ounce or two of hot plastic into the runner followed be an injection. In this mold, that ounce or two would go down that runner, fill the bottom cavity, might get a bit in middle cavity followed by shot. That’s exactly what you would see in final baits. Bottom cavity would be pour color, you might get some core effect in middle cavity, top cavity would be shot color for the most part. That’s why every mold doesn’t do core shots well.
