: The two halves of the mould are held together under high pressure.
While traditional moulds are precision-milled from tool steel, beginners and prototypers often use or 3D-printed moulds . Injection Moulds for Beginners
For a deep dive into the technical details and step-by-step assembly, Rainer Dangel’s Injection Moulds for Beginners is a standard industry resource that uses a practical "bowl with lid" example to teach the fundamentals. Injection Moulds for Beginners | ScienceDirect : The two halves of the mould are

: These define the internal and external shape of the part.
For those starting in mould design, several "rules of thumb" ensure a part can be successfully manufactured:
A standard injection mould is a complex assembly of high-precision steel parts:
