SCZA Oil-Free Slide Units for Loose Core - Inclined Pin Height Fine Tuning

SCZA oil-free slide units are used in injection mold tooling where a loose core must travel with controlled positioning via an inclined pin mechanism, especially in compact cavities with undercut features. These units support inclined pin height fine tuning, which helps maintain consistent core engagement/disengagement over long production cycles.

• Automotive connector and housing molds: Use the fine-tuning range to stabilize loose-core motion and reduce the risk of misalignment during high-cycle molding. The oil-free design helps limit friction and wear in frequently actuated slide systems.
• Consumer electronics and appliance parts: When tight repeatability is needed for subassemblies, select the unit with the correct inclined pin diameter (12–30 mm) to ensure smooth, stable travel.
• Small-feature multi-part molds: For slide plate angles in the 2–10° range, the product’s oil-free slide mechanism supports predictable motion without relying on lubrication.

The provided product specifications focus on functional fit parameters (inclined pin diameter and slide plate angle). No steel grade, heat treatment state, hardness (HRC), or surface treatment is included in the input data for this SCZA variant.

• Material/heat treatment: Not specified for this item; therefore, hardness and wear-resistance trade-offs (e.g., quenched & tempered vs. nitrided) cannot be stated from the current dataset.
• Manufacturing process: Not specified; however, oil-free slide mechanisms are typically engineered to maintain low friction in repeated cycles, emphasizing dimensional stability for consistent motion.

Correct selection is primarily determined by matching the inclined pin diameter D and the mounting angle of slide plate A to your mold geometry. This SCZA unit is applicable for D = 12, 16, 20, 25, or 30 mm.

• Step 1: Choose pin diameter: Select the SCZA variant whose D matches the inclined pin used in your loose core mechanism.
• Step 2: Verify slide plate angle: Confirm your slide plate A mounting angle is within 2–10° (or the dataset’s available value of 0° when applicable). This affects the effective travel and engagement behavior.
• Step 3: Match cavity/core motion: Use the pin-height fine tuning capability to align the loose core timing to cavity requirements, especially for undercuts.
• Tolerance/fit: No tolerance values are provided in the input data, so engineers should rely on their own pin and plate machining tolerances and confirm assembly clearance during trial fitting.
