Detail Models Inc. bodies are examples of the "blow-mold" process, in contrast to "vacuum-forming". Blow mold bodies are made in a manner similar to the way plastic bottles are made. With blow-molding, the fine details (body lines, grilles, scoops, gas caps, etc.) are molded into the outside of the body (where they belong) and stand out much better. Unfortunately, negative molds are considerably more difficult and expensive to make than positive molds, so the blow-molding process didn't work out so well economically for making slot car bodies.
