- Product Tolerance: ±0.005mm
- Product Hardness: Varies depending on material and heat treatment
- Customizable: Supports non-standard customization
- Product Application: Plastic molds, die-casting molds, injection molds
Product Description
Introduction
The special shaped ejector pin improves molding flexibility and efficiency by enabling precise ejection of complex or irregularly shaped plastic parts, reducing product deformation and cycle interruptions. Compared with standard ejector pins, it provides better customization adaptability, higher durability, and more stable performance in demanding production environments. This component is widely used in automotive interiors, electronics housings, medical devices, and precision plastic molding industries where complex part geometry, high accuracy, and consistent production quality are required.
Three Key Customization Aspects, Tailored to Your Needs
Matching different customization methods to meet various requirements.
Precision Manufacturing, Excellent Quality
High-Quality Material Selection
The material can be processed from ordinary SKD61, Taiwan SKD61, Japanese vacuum nitrided SKD61, SKH51, etc., based on customer requirements, to suit different operating environments.


High-Temperature Resistance
The product undergoes vacuum nitriding heat treatment, allowing it to withstand temperatures over 600°C. It is 3 times more wear-resistant than conventional processes, making it highly durable and heat-resistant.
High Precision
The tolerance accuracy is high, within ±0.002mm. It has excellent concentricity and perpendicularity, ensuring greater precision and durability.


Strong Stability
Crafted with precision, the product offers strong stability and excellent resistance to bending. It is less prone to deformation, extending its service life by 35%.
