What Is a Blade Ejector Pin?
Blade ejector pin, also known as flat ejector pins,When traditional cylindrical ejector pins encounter challenges in ejecting thin-walled, narrow-slot, or complex-structured parts, blade ejector pins offer a superior solution. Their flat/rectangular cross-section design better accommodates these specialized spaces and distributes ejection force by expanding the contact surface area. This significantly improves ejection performance, effectively preventing product deformation, flash marks, and scratches.
As an ejector pin supplier with over 23 years of experience, HTX offers custom manufacturing based on provided drawings, with materials including SKD61 and stainless steel. Precision grinding ensures reliable ejection without displacement.

Blade Ejector Pin Types and Customization Solutions
HTX has standard pins in stock, and we can also custom non-standard blade ejector pins for special requests.
Universal flat structure suitable for routine ejection scenarios in most injection molds.
Width, thickness, and length can be customized based on mold space and product geometry.
To ensure performance in special environments, SKD61, stainless steel and tool steel can be choose.
Applications of The Blade Ejector Pin
The flat cross-section design of blade ejector pins is particularly suitable for scenarios with special ejection requirements:
Thin-Walled ProductsTheir wide contact surface effectively distributes ejection force, preventing wall perforation or deformation.
Complex or Confined SpacesThe flat shape accommodates irregular areas and narrow gaps where cylindrical pins are difficult to position.
High-Aesthetic RequirementUniform force distribution significantly reduces the risk of surface defects such as eject marks or indentations.
Anti-Rotation EjectionThe non-circular cross-section effectively prevents component rotation or displacement during ejection.
Manufacturing of The Blade Ejector Pin
Our blade ejector pins are manufactured entirely in-house using high-performance equipment throughout the entire production process to ensure product performance:
Premium certified raw materials such as SKD61 and stainless steel are selected. After precise CNC machining, they undergo heat treatment or nitriding, followed by high-precision grinding and fine polishing. All finished products undergo rigorous dimensional and visual inspection to ensure each blade ejector pin operates stably under high-frequency, high-intensity conditions.

How to Order Custom Blade Ejector Pins from HTX
Send your drawing with blade dimensions, head configuration, and any special requirements.
Our engineers check tolerances, material suitability, and manufacturability before moving forward.
Blade profiles are CNC-machined to exact specifications, with tight control on flatness and thickness.
Optional nitriding or coating is applied, followed by dimensional checks and surface finish verification.
Pins are securely packed and shipped to meet your schedule—no damage, no delay.
Bladed ejector pins distribute ejection force by increasing contact area, effectively preventing white marks and deformation on products. Their compact cross-section allows access to narrow areas unreachable by round pins. The stable, non-rotating structure ensures precise ejection positioning during operation.
Overall, it achieves more uniform force distribution, thereby enhancing mold durability.
Yes, both of the thickness, the width and the length can be customized. Suitable both for metric and imperial. We can custom the pins 100% according to the drawing.
No, the blade ejector pin is primarily used for special structural requirements where the round one cannot reach.
In high-temperature environments, SKD61 is recommended. In rust-prone environments, stainless steel is recommended.
Yes, we will control high-precision tolerance according to the mold requirement. We can meet ±0.002mm for the tolerance.
Lead time depends on the complexity and quantity of the custom order. Standard production takes 7 days. Rush orders can be accommodated upon coordination.
