Mold base nomenclature
The standardization and mass production of mold bases has resulted in naming conventions for basic mold parts that follow across all manufactured lines of moldbases and mold components. On top of that most manufacturers have adopted the DME dimensional standards for plate size and feature location.
Most molds can be built using standardized mold bases. Many internal components also may be purchased as standardized components. Here are a few of the key mold components readily available off the shelf.
Leader pins and shoulder bushings
Guided ejection systems
Ejector pins, sleeves and blades
Due to the variation between the shapes of plastic parts many of these standard components must be customized for your aplication.
The leading companies selling mold bases and/or hardware include PCS, DME, Progressive, Misumi, Hasco, and National.
