Metric Close Space Straight Punches with XCN Coating

Where used: close-space straight punches are common in production injection mold tooling whenever the tool designer needs a punch to enter a tight cavity area and still maintain stable alignment during repeated cycles.

Scenario 1 – Automotive connector housings: use these punches in forming/punching operations for small features such as local bosses, vent details, or insert seats where die space is limited. The close-space straight geometry supports consistent engagement even as the die surfaces wear over runs.

Scenario 2 – Consumer electronics and thin-wall parts: apply them for clean, repeatable perforations or relief features in tight, multi-cavity layouts. The XCN coating is suited to reduce friction at the punch/die interface, supporting longer wear life when cycles are high and misalignment tolerance is small.

Scenario 3 – Medical device housings: for features requiring predictable repeatability, select the head style that matches the punch approach path—angled head (AWX) for constrained tool access or regular head (AXX) for straight engagement.

These metric close-space straight punches are supplied with an XCN coating, engineered to improve sliding performance against the mating die steel. In mold tooling, that typically translates to lower friction, reduced galling risk, and improved wear resistance under repeated punching loads.

Heat treatment: the provided specifications do not list the underlying base steel grade or hardness (HRC), so heat-treatment state (e.g., quenched & tempered, nitrided) cannot be confirmed from the data given. When selecting for high-cycle service, verify the manufacturer’s datasheet for the base material condition and target HRC.

• XCN-coated variants generally offer a wear/friction advantage versus uncoated punches in tight die environments.
• Angled head vs regular head affects tool layout and contact geometry; it does not change the coating’s core purpose of protecting the punch surface during sliding engagement.

Start with cavity/core feature matching: choose the correct punch Type based on tool access—Angled head = AWX or Regular head = AXX. This selection helps ensure the punch can enter the mold space without interference while maintaining straight alignment at the working end.

Match length (L): the fixed L range is 40–100 mm. Use L to provide sufficient stick-out and guidance for your punch holder and the depth of the die cavity/core feature.

Verify cross-section dimension (P): the fixed P dimension is 0.8–7 mm. P should correspond to the intended punch working diameter/profile relative to the mating die opening and the required clearance/land geometry.

• Tolerance & fit: keep clearance consistent with the mating die opening design; tight close-space tooling typically demands controlled alignment and minimal side loading.
• Configurable vs fixed: in this dataset, only Type is variable; L and P are defined within the stated ranges.
