The DME “B” Series Mold Base offers economy of design without sacrificing the high-quality steel and workmanship of the “A” Series. The two mold bases are identical except for the “B” Series “two-plate” design. A thicker “A” plate acts as both Top Clamping Plate and upper Cavity Plate. Similarly, a thicker “B” plate eliminates the need for a Support Plate on the “B” side of the mold. The “B” Series is sometimes specified for single-cavity plastics molds or die-cast dies where the cavity and core are machined directly into the Cavity Plates; or where overall mold height is critical. As a two-plate design, cavity inserts have to be

“B” Series Mold Bases are available in the same variety of steels, sizes and plate combinations as the “A” Series. Since the clamp slots are located in the “A” plate, the recommended minimum “A” plate thickness for a “B” Series Mold Base is 1.875. If an “A” plate less than 1.875 is desired, exact clamp slot and center hold specifications must be provided. Unless otherwise specified, the size and location of return pins and screws will be identical to those of the corresponding size “A” Series Mold Base. In addition, unless otherwise specified, the riser height will be supplied to conform with the standard “C” dimension listed for the corresponding size “A” Series Mold Base. To create assembly item number: Use item number prefix shown in chart at right, followed by A and B plate thickness codes. Example: 10.875 x 14 B-Series with 2.375 A-Plate and 2.875 B-Plate = 1114B-23-27
