: The mould opens, and the finished part is pushed out. Key Mould Components
: The plastic solidifies within the mould to take its final shape.
: A set of pins or plates that push the cooled part out of the mould.
: Maintaining uniform wall thickness helps prevent defects like "sink marks" or warping during cooling.
: These define the internal and external shape of the part.
: Includes the sprue, runners, and gates that guide the molten plastic into the cavity. Beginner Design Guidelines
Injection moulding is the primary manufacturing process for creating mass-produced plastic parts, ranging from simple bottle caps to complex automotive dashboards. The Core Process
While traditional moulds are precision-milled from tool steel, beginners and prototypers often use or 3D-printed moulds .
