Although it is not a new technique, the use of slide molds allows more accurate reproduction of details than traditional two-piece molds. This is done by using injection molds with moving parts (known as "slides") that are inserted into the mold to form parts and then removed so the part can be extracted from the mold. It helps increase the authenticity of the model and reduce the number of parts by molding details onto larger parts. Weld patterns between plates, gratings, one-piece hull and turret interior are common features included in Dragon kits. The usage of slide mold technology has caused Dragon to rely less on photo-etched parts (See Smart Kit, below).
