At a glance
Gate layout is part of the material-performance problem in a moulded composite. It can influence the flow pattern and the orientation of reinforcement within the part.
Key points
- A specimen moulded separately may not reproduce the orientation of a complicated production component.
- Use an appropriate inspection or modelling method to investigate orientation where it matters.
- Treat a gate change as more than a cosmetic tooling adjustment.
Technical context #
A specimen moulded separately may not reproduce the orientation of a complicated production component. Measurements from one direction should therefore not be assumed to apply uniformly throughout the part.
What to measure and document #
Use an appropriate inspection or modelling method to investigate orientation where it matters. Compare predictions against physical samples. Test critical directions and locations, and retain the tooling revision with the manufacturing and laboratory records.
Implications for development and specification #
Treat a gate change as more than a cosmetic tooling adjustment. Reconfirm relevant performance before releasing the revised component. The objective is a reliable relationship between the manufacturing process and the intended load path, not the highest result from an unrelated standard bar.
