Definition
A reference point marked on a composite or sheet metal part that corresponds to a specific location on the original mold or tooling. Mold points are used during layup, trimming, and assembly to ensure the part matches the engineered shape and aligns correctly with adjoining structures.
Plain English
A marked spot on a part that matches a known spot on the mold it was made from, used as a reference for shaping, cutting, or fitting the part correctly.
Context Anchor
Seen in aircraft structural drawings, templates, and layout work for formed or contoured airframe parts.
Derivation
From 'mold' (the form a part is shaped in or on) and 'point' (a specific reference location). Together: a reference location tied back to the mold, so the finished part can be checked against the original tooling.
Why Pilots Care
A pilot may not use mold points in flight, but accurate mold points help maintenance technicians repair or build aircraft parts so the finished shape matches the approved design.
Analogy
It is like a dot on a pattern used for cutting fabric: the dot itself is small, but it helps the finished piece come out in the right shape.
Intuition Check
Do not read mold here as mildew or contamination. In this term, mold means the intended shape or form of an aircraft part, and point means a precise reference location on that shape.
Example Sentence 1
The technician aligned the mold points on the new composite skin with the matching marks on the airframe before bonding.
Example Sentence 2
After cure, measurements from the mold point confirmed the repaired surface matched the original contour.
