A twin injector does lams nicely. All of the pictures of the ripper baits are done using a twin injector. I've never been a fan of plates and find that splitting a color can be done as easily by hand filling half of a mold if the mold is oriented to a top and bottom. The single cavity of the Ripper cnc molds injects great with the twin and the baits are slick too. The bottom and single cavity in the Essential mold responds well to the twin as well. Having several of the molds can increase productivity, especially when a twin is used.
