Slider and Lifter Mold Quote Checklist for Undercut Features
A mold quote that only counts undercuts skips the actuation and wear decisions that drive tooling cost and long-run reliability. This checklist lists what to send before a slider or lifter mold tooling quote.
Slider and lifter mold quotes depend on undercut direction, actuation mechanism and wear point maintenance, not only the number of undercuts.
Undercut direction and mechanism choice
Side undercuts usually need a slider, while angled or internal undercuts may need a lifter or collapsible core. The direction and depth of each undercut determines which mechanism fits.
- Undercut direction: side, angled or internal.
- Undercut depth and draft angle available.
- Whether a slider, lifter or collapsible core fits the geometry.
Actuation and cycle time impact
Mechanical, hydraulic or cam-actuated slides each add cost and cycle time differently. The choice should match production volume and cycle time targets.
- Mechanical cam versus hydraulic cylinder actuation.
- Cycle time impact of the chosen actuation method.
- Interference risk between multiple sliders or lifters.
Wear points and long-run maintenance
Slides and lifters wear faster than fixed mold surfaces, so maintenance planning should identify wear points before the mold reaches high shot counts.
- Angle pin, cam track and slide wear points.
- Lubrication and maintenance schedule for moving components.
- Expected annual shot count and slide life estimate.
