Metric Straight Ejector Punches XCD Coating

These metric straight ejector punches are used in injection molding toolsets and precision die stations where consistent part release is critical, especially under high cycle counts.

• Automotive and industrial connector molds: their straight geometry supports direct, reliable ejection from narrow features, helping maintain dimensional stability while ejecting post-molding cores or inserts. The XCD-coated surface improves wear durability for long production runs.
• Packaging and appliance housings with fine ribs: when ejection forces must be controlled to avoid scuffing, the coated punch face contributes to stable sliding performance across repeated strokes.
• Precision die work for small metric components: the flexible L (50–90 mm) length range allows matching the ejector stroke and support structure to the press/tool layout.

Overall, the XCD coating and metric straight format make this variant well-suited for repeatable ejection in compact die cavities where wear and surface stability influence cycle-to-cycle consistency.

The provided product specifications focus on geometry and coating rather than a specific steel grade. As such, the key material performance attribute for this variant is the XCD coating, which is selected to enhance surface durability during repeated ejection and sliding contact.

• Wear resistance: the coated punch face improves resistance to abrasive wear and micro-galling under repetitive forming loads.
• Toughness trade-offs: while a hard surface generally increases wear life, it can be more sensitive to edge loading; proper alignment and support are therefore important to protect the punch tip during ejector actuation.
• Heat treatment state: not specified in the provided data; please confirm the base steel grade and heat treatment with your Axiom Molds representative for hardness targets and tempering requirements.

If multiple coating or material options are offered, selection typically balances surface hardness for wear life versus base toughness for shock resistance.

To select the correct straight ejector punch dimensions, start by matching the required ejector reach to the tool layout and cavity/core position.

• Length (L): choose within the fixed range of 50–90 mm. Use longer lengths when you need additional protrusion to fully clear the part, and shorter lengths to reduce unsupported stick-out and bending risk.
• Diameter/width parameter (P): select from the fixed P = 5–16 mm range based on the clearance and guidance requirements in your ejector plate and die bushing.

Ensure the punch is aligned with the ejection axis to avoid side-loading on the XCD-coated surface. When fitting into an ejector guide or bore, verify the available clearance for smooth motion and to prevent binding during thermal expansion. If your design uses a standard guide system, match the P dimension to the corresponding bore/guided feature, then set L to meet the required part release stroke without excessive overhang.
