Etymology: "Preform" is a plain compound: the prefix "pre-" (before, in advance) joined to "form" (shape). The sense is literal and technical, meaning a shape made before the final product exists, as with a rough blank that is later finished or moulded. Its parts are traceable back through Latin, where "prae" meant "before" or "in front of," and "form" came into English through Old French from Latin "forma." The prefix "pre-" reached English through Middle English, which is why the word can be read at a glance: nothing is hidden in it, and it simply says what it does. The compound was built in English from these two existing pieces, so the history is a matter of assembling known parts rather than a single dramatic turn in meaning.
