What machine is this ejector pin compatible with?

This ejector pin is designed for use with corner nailing machines (钉角机), including both pneumatic tabletop and CNC-type models that use standard V-nail feeding systems.

What material is the ejector pin made from?

The pin is manufactured from hardened tool steel, giving it excellent wear resistance and durability under repeated high-impact nailing cycles.

Can I use this pin for other nail sizes?

This pin is specifically matched to the nail channel dimensions of standard corner nailers. Always verify the cross-section of your machine's push-pin slot before ordering.

Corner Nailing Machine Ejector Pin – Professional Framing Tool Component

The Corner Nailing Machine Ejector Pin is a critical consumable for any picture-framing workshop relying on pneumatic or CNC corner nailing machines. Without a properly functioning ejector pin, nail feeding becomes erratic and corner joints suffer misalignment, leading to wasted moulding and costly rework.

Key Features of the Corner Nailing Machine Ejector Pin

  • Square cross-section rod for precise guidance inside the nail channel
  • Precision-ground pyramid (diamond) tip on both ends for consistent V-nail contact
  • Smooth surface finish to reduce friction and prevent jamming
  • Compatible with standard pneumatic and CNC corner nailers

Why a Quality Ejector Pin Matters

In high-volume framing production, the Corner Nailing Machine Ejector Pin cycles thousands of times per day. A worn pin causes nail misfeeds, incomplete nail seating, and costly frame rejects. Replacing it with a precision-made part keeps your machine running at peak efficiency.

Application

Used exclusively in corner nailing machines (钉角机). Works with the nail feed slot (送钉槽) and nailing die (钉模) to drive V-nails squarely into mitered frame corners. Suitable for softwood and hardwood mouldings.

Installation Tips

Clean the nail channel before installing the Corner Nailing Machine Ejector Pin. Insert with the pyramid tip facing the nail bed. Test with dry cycles before resuming full production.
