For Beginners — Injection Moulds

: The plastic solidifies within the mould to take its final shape.

: These define the internal and external shape of the part.

: Common materials for beginners to work with include ABS , Nylon , and Acrylic , each having different shrinkage rates that must be accounted for in the mould design. Manufacturing & Prototyping Injection Moulds for Beginners

: Vertical faces should have a slight taper (typically 0.5 to 1 degree) to allow the part to slide out easily without sticking.

: The frame that holds all other components in place. : The plastic solidifies within the mould to

: Maintaining uniform wall thickness helps prevent defects like "sink marks" or warping during cooling.

: Made from aluminum or epoxy, these are cheaper and faster to produce but only last for a few hundred or thousand cycles. Manufacturing & Prototyping : Vertical faces should have

: Internal passages for water or oil to regulate the temperature of the mould.
