LSR Part Removal: Flexible Part Handling and Mold Access

LSR parts can be flexible, thin, sticky, or easy to deform depending on geometry and material grade. Part removal should be reviewed early because it affects cycle stability, scrap, operator workflow, and possible automation planning.

For vertical molding, table layout and mold access may determine whether operators can remove parts safely and repeatably.

What You May See

• Parts stretch or tear during removal.
• Parts stick to the cavity or core.
• Operators need extra time or special handling.
• Part shape changes after removal.
• Cycle time becomes inconsistent because removal is difficult.

Review Points

Review part removal together with material cure, mold design, and machine access:

• Part thickness, undercuts, ribs, seals, and thin edges.
• Mold release, surface finish, and ejector support.
• Curing stability before removal.
• Manual access to the lower mold or table area.
• Whether parts can be removed by hand, air assist, robot, or custom fixture.
• Whether flexible parts need support after removal.

Machine Configuration Notes

Slide table machines may help when the lower mold needs to move out for safer manual access. Rotary table machines may be discussed when loading and removal can be separated by station, but suitability depends on mold and part handling.

The correct approach should be reviewed with mold drawings, part samples or drawings, material grade, and target output.
