DLC Coated Jector Punches Single-Stepped

Single-stepped jector punches are used in injection and die tooling where consistent downward travel and stable alignment are critical. This DLC-coated variant helps maintain punch surface integrity during repeated jector actuation and die cycling.

• Automotive and appliance die operations: For die sets that run frequent strip/punch cycles, the stepped shank improves guidance repeatability, reducing lateral wear and improving positioning. The DLC surface is suited for sliding and impact loading against die components.
• Electronics connector and terminal stamping: When tight hole-to-punch register is required, engineers can select a shank diameter in the 4–25 mm range and match the tip geometry (round/rectangle/oblong/double-flatted) to the cavity form. The SKH40-equivalent base plus DLC helps extend punch life in harder, abrasive contacting areas.
• Production dies with jector-type actuation: Use the single-stepped design to support reliable standard shank mounting in tool sets, helping stabilize the punch during return and rebound.

This product uses SKH40-equivalent powdered high-speed steel as the core material. HSS powder grades are engineered for uniform carbide distribution, supporting high wear resistance while retaining adequate toughness for punch applications.

• Wear resistance: The DLC (XCD) coating improves resistance to sliding wear and surface degradation under repeated jector action.
• Hardness/heat treatment: The meta description specifies the SKH40-equivalent base grade; specific HRC and the exact tempering/quench condition are not provided in the provided data, so hardness should be verified to match your tool steel spec sheet.
• Trade-offs: Compared with softer tool steels, HSS typically offers higher abrasion resistance, but can be more sensitive to edge chipping if mounting/clearance is not controlled.
• Coating vs. base: DLC primarily protects the surface; the underlying HSS provides toughness to tolerate intermittent impact loads.

Select dimensions by matching the punch’s shank and head features to your die set jector guidance and cavity punching requirements. The shank diameter D is available from 4–25 mm with a specified tolerance of +0.005/0, m5, so choose the diameter that corresponds to your guide/bushing bore and desired fit.

• Tip geometry: Pick the tip shape (round, rectangle, oblong, double-flatted round, radius rectangle) and use PC (1.8–9 mm) plus P (1–18) to align the tip region to cavity geometry.
• Length match: Choose the L dimension from the available ranges (e.g., 40–80, 40–100, 50–80, 50–100, 60–100 mm) and set the full-length alteration via LC (32–90.1 mm).
• Tolerance considerations: The toleranced shank diameter affects guidance friction and repeatability; confirm your mounting/guide design accounts for m5 fit behavior.

Configurable vs. fixed: Tip shape, shank diameter D (4–25 mm), and several length/alteration parameters (L, LC, LCT, LMT) are selectable across stated ranges.
