WebAs a general rule, we recommend one degree of draft for every 0.0005 in. to 0.0006 in. (0.0127mm to 0.01524mm) of texture depth, or roughly 6 to 7 degrees for a typical wood grain or leather-like finish. As always, refer to the our DFM (design for manufacturability) analysis that accompanies your online quote. WebApr 10, 2024 · In reaction injection molding or RIM, a thermosetting resin is used, rather than a thermoplastic. Two different resins that will react when combined and heated are squirted into the mold, which is then heated up in order for the part to cure. Thus the "reaction" refers to the thermosetting, as when you mix up a two-part epoxy.
