引用自Deskthority Double shot词条关于Double shot工艺的生产过程

Production
As the name suggests, double-shot moulding is a two step process. In the first step, the legend or graphics to be placed on the keycap, are moulded in plastic[3]. The plastic insert, resulting from the first step, is then placed in another mould, while plastic is inserted under heat to combine both moulds to a single piece keycap.

Despite the name, the moulding process is not restricted to two colours: triple and quadruple[4] shot keycaps exist, where two or three different legend colours are present on a single keycap. The use of more than three colours is however quite rare. More commonly, where multiple legend colours are required, the additional colours are provided using pad printing (dye sublimation would be unsuitable with the ABS material used in double-shot moulding). This is especially true where the extra text is printed on the front of the keycap, such as with NeXT keyboards.

已获知信息：
SP、太豪、GMK键帽所使用工艺均为双色注塑（Double Shot）。
所有二色开口笑对应的工艺应为——单次注塑/注塑成型，英文为Insert molding
所有闭口键帽对应的工艺为——双色注塑，英文为 Double-Shot/Two-Shot/Dual-Injection。
注塑成型和双色注塑都为包胶模具/二次成型工艺的一个细分。
