Question
Name four features injection moulding forces onto a design.
Answer
Draft angles so the part releases, uniform wall thickness so it cools without sinking, radii instead of sharp internal corners, and no undercuts.
Question
What is a split line and why does it matter?
Answer
The line where the two halves of the tool meet, which cannot be avoided. A designer chooses where it runs so it looks deliberate rather than like a fault.
Question
How does an assembly line shape a product?
Answer
Parts are designed so they fit only one way round and the product assembles from one direction — which is why so many products have all their screws on one face.
Question
Why do product families share a colour palette?
Answer
Colour changes mean a machine changeover and wasted material, so colours are run in batches from a limited range.
