US Standard mold bases by DME refers to the primary DME mold base offering in the USA and Canada. This standard was developed by DME in the late 1940s and has been an industry standard for over 60 years. Today, this includes A-Series, B-Series, X-Series, AX-Series, and T-Series which may vary in the number of plates used but for the most part, component positions in the X- and Y-axis directions are positioned in the same locations. For this reason, only the A-series plan views are detailed in the DME Mold Bases and Plates catalog.
MoldBasics, and Edge Base are modeled after the US Standard A-Series mold base, with some variations. MoldBasics was offered by DME as an economical form of the A-Series with some reduced or simplified features (although the MoldBasics mold base would be produced with the same exacting standards and quality as a US Standard A-Series mold base). For example, a MoldBasics mold base would not be shipped with finished ground parting line surfaces, and the mold maker would be expected to finish-grind the parting line surfaces.
The Edge Mold Base is a unique standard offering, modeled after the US Standard A-series. However some of the features are in different positions versus DME A-Series. Please refer to the appropriate pages in the DME Mold Bases and Plates catalog for details specific to the Edge Mold Base.
