Metric Straight Ejector Punches XVP Coating

Where it’s used: Metric straight ejector punches with XVP coating are used in die and mold assemblies where stable ejection guidance is critical—especially in progressive dies and punch-and-die tooling. Their straight geometry helps maintain alignment between upper and lower tooling during repeated punch cycles.

Scenario 1: Progressive dies for electrical/connector components—these punches support consistent feed and ejection because they are designed for repeatable fit-up in metric tool sets. The XVP coating is suited to maintain smooth surface contact as wear accumulates over production.

Scenario 2: Automotive bracket and sheet-metal stamping dies—stable punch guidance helps reduce misalignment-related wear, improving functional reliability across long runs. Coated surfaces help extend punch service life under frequent, high-cycle impacts.

Scenario 3: General industrial forming tools—when ejector performance must remain consistent, controlled metric dimensions support predictable assembly and ejection behavior.

• XVP coating supports wear resistance for tooling durability
• Straight punch form factor promotes accurate alignment in die sets

Material and coating: This product is specified as a DAYTON Metric Straight Ejector Punch with an XVP coating, engineered to improve wear resistance at the punch working surface. The coating’s role is to reduce surface degradation during repeated ejection cycles, supporting stable guidance.

Heat treatment: No steel grade, heat-treatment state (e.g., quenched & tempered, nitrided), or hardness (HRC) values are provided in the available specifications. Because these parameters directly affect wear/impact trade-offs, they should be confirmed before specifying for unusually abrasive materials, high-impact applications, or tight lifter guidance requirements.

• Trade-off (general): Increased surface hardness typically improves wear resistance, but may reduce toughness if not properly heat-treated—confirm grade/HRC for your load profile.
• Coating benefit: XVP coating is selected to enhance durability under guidance and friction exposure.

Step 1: Match the length (L) to your ejector stroke and tooling stack-up. This series is available in L = 50 to 90 mm. Select a length that provides full functional engagement without bottoming out in the die base or interfering with adjacent components.

Step 2: Verify the P dimension based on your guidance and support layout. The fixed P = 5 to 16 mm range must correspond to the required punch-related feature in your die set (e.g., the defined guidance/support dimension used by your design standard).

• Use the combination of L and P to meet cavity/core spacing and ejection clearance.
• If your assembly includes precision guide components, confirm the required fit class and any local tolerance standard—this dataset lists dimension ranges but does not specify tolerances.
• Configurable dimensions: Length and P are specified as fixed-range options for ordering.

Fit guidance: For stable ejection, ensure your chosen P dimension is consistent with your die set’s guidance clearances and tolerancing approach; otherwise, wear and sticking risks increase during repeated cycles.
