How far away should the vacuum ports be placed in relation to the part being laid up?

Positioning the vacuum ports correctly is crucial for effective vacuum bagging during the composite layup process. A placement of 2 inches minimum from the edge of the part ensures that the vacuum evenly distributes across the entire surface of the layup. This distance allows for optimal resin infusion and helps to avoid air pockets or dry spots that could compromise the integrity of the composite part.

Furthermore, placing the ports too close to the edge can lead to uneven pressure distribution and potential failure in achieving the desired consolidation of the laminate. It is essential to balance the distance to maximize efficiency in the vacuum process while avoiding complications that can arise from too close a placement. Hence, the 2-inch guideline is widely accepted in the industry for maintaining the performance and quality of composite lamination.
