Mini Slide Core Units

Ultra-compact mini slide core units for small undercuts and tight spacing.

Boundary Check: Mini Units vs Standard Slides

Mini slide core units are self-contained, pre-engineered assemblies that save design time, but they have strict load limits.

✅ You're in the Right Place If:

  • The undercut feature is small (e.g., small holes, snap fits under 10mm wide).
  • Mold space is highly constrained (multi-cavity medical/electronic molds).
  • You want to eliminate the design time required to calculate pin angles and clearances.

🔄 Consider Switching To:

If the required stroke exceeds 15mm or injection pressure is massiveStandard Slide Cores — Mini units lack the structural footprint to resist high tipping moments.

Compact Design Principles

Integrated Kinematics

Mini slide units encapsulate the angled pin, sliding body, and locking block into a single cylindrical or compact rectangular cartridge. This guarantees perfect alignment, as the critical tolerances (H7/g6) are machined at the factory rather than relying on the mold builder's plate boring accuracy.

Pre-Load Mechanisms

Many mini units utilize internal springs rather than angled pins for actuation. The mold closing force compresses the spring and locks the core, while opening releases the spring to pull the core. This entirely eliminates the need for angled pin clearance calculations.

Application Scenarios

💉

Medical Syringe Molds (32+ Cavity)

Requires 32 tiny side-holes. Designing 32 traditional slides is impossible due to space constraints.

Recommended:Cylindrical Mini Slide Units (Ø12mm)
Design Rule: Ensure the mold base pocket for the mini unit has a locating tolerance of +0.02/-0.00 to prevent unit shifting under pressure.
