TiCN Coated Jector Punches

This jector punch is used in injection mold tooling wherever repeatable part ejection demands high cycle stability and reduced wear at the pin tip. The TiCN surface is particularly suited to environments with abrasive contact against cores/cavities, helping maintain ejection consistency over long runs.

• Automotive connector and sensor housings: Ideal for ejection in high-cycle molds with tight functional surfaces, where the round or rectangle tip shapes and the spring reinforced option can better absorb impact during ejector travel.
• Consumer electronics housings: Suits precision ejector systems that require controlled tip geometry (e.g., oblong, double flatted round, radius rectangle) to match gate/part contours while limiting abrasion-driven dimensional drift.
• Appliance and industrial component molds: The heavy-load variant supports stable operation under higher ejection force profiles, while the spring reinforced jector configuration improves impact resistance for reliable ejection.

As a TiCN coated jector punch set, the functional performance relies on the hard TiCN coating for abrasion resistance at the contacting tip. While the base steel grade is not specified in the provided data, the coating is typically selected to balance surface hardness and wear life against the underlying core’s toughness for impact-loaded ejection.

• Wear resistance: TiCN reduces surface abrasion, improving tool life when the tip repeatedly contacts formed features.
• Toughness trade-off: Coatings enhance hardness and wear performance, but ejection impact requires a ductile substrate—this is why the design includes a spring reinforced jector option to better manage shock loads.
• Heat treatment state: Specific heat treatment and hardness (HRC) values are not provided in the available specifications, so selection should be confirmed with the supplier’s material datasheet for the chosen build configuration.

Select the punch by matching both the shank diameter and the tip geometry to the ejection requirement of the cavity/core interface. First choose the Shank diameter D within 4–25 mm, and note the D tolerance: +0.005/0 (m5) to ensure proper guide fit in the ejector plate and bushings.

• Tip geometry: Choose Tip shape (Round, Rectangle, Oblong, Double Flatted Round, Radius Rectangle) and confirm P (1–18 mm), W (1–6 mm), and corner R (0.15 mm) are compatible with the part surface contact area.
• Length matching: Use the L option you need (ranges listed: 40–80, 40–100, 50–80, 50–100, 60–100), and then verify the Full length alteration (LC: 32–90.1 mm) / LCT / LMT adjustments for the total stack-up.
• Configurable variants: Select Jector type as Standard or Spring Reinforced, and confirm the heavy-load option if required by ejection force.
