Once the formalities of quoting, placement, and design approval have been completed, the actual

construction of the mold will begin. The mold base becomes of extreme importance, as it not only will retain and position the cavities and cores, but contains the plastic feed system and the temperature control circuits. The mold base is the means by which the cavities and cores are coupled to the molding machine. Standardized mold bases are available in almost any form desired. (See Fig. 7-2.) These mold bases are designed and available with widths inch less than the standard tie bar spacing offered by machine manufacturers. The standardizing of mold bases was developed by 1. T. Quarnstrom of Detroit Mold Engineering (later shortened to D-M-E) during World War 11, to better meet the need to supply completed molds quickly for the war effort. These standard mold bases are available in a variety of widths and lengths, which meet the majority of mold requirements. Standardized mold bases offer many advantages to the moldmaker, including extremely quick delivery, cost savings over one-of-a-kind construction, and a very high-quality product that will complement the quality of the cavities and cores, on which the moldmaker now can concentrate. Additionally, the use of standardized mold bases quickens design time, as placement of the basic components, such as leader pins and bushings, return pins, locating ring and sprue, has been predetermined.
