DIN 9861 D

2025-08-29

DIN 9861 ejector pins, various ejector pin types, and Dayton punches for precision molds, ensuring durability, accuracy, and reliable injection molding performance.

In the field of injection molding and die casting, the choice of ejector pins directly impacts production efficiency and product quality. Among the international standards, DIN 9861 D ejector pins are widely recognized for their precision, durability, and reliability. Featuring a 60° conical head design, these pins ensure stable performance and longer service life, making them a preferred solution in automotive, electronics, and medical molding industries.

⚙What is DIN 9861 D?

DIN 9861 D refers to a specific type of ejector pin defined by the German industry standard DIN 9861. Ejector pins are essential components in injection molding and die casting, used to push the molded part out of the cavity once the forming process is completed.
The Type D variation features a conical head (60°) design, offering higher stability and better load distribution compared to flat-head ejector pins.

➤ Key Features of DIN 9861 D Ejector Pins

Standardized Design – Manufactured according to DIN 9861 D, ensuring compatibility and interchangeability across molds worldwide.
Conical Head (60°) – Provides strong structural support, reduces stress concentration, and minimizes risk of pin breakage.
High-Precision Tolerances – Ground cylindrical body with tight tolerances for smooth operation inside guide holes.
Durable Materials – Commonly made from hardened tool steel, HSS, or alloy steel, offering superior hardness (HRC 58–62) and wear resistance.
Surface Treatments – Options include nitriding, TiCN, TiN, or WPC coating, enhancing lifespan and reducing friction.

➤Applications

DIN 9861 D ejector pins are widely used in:

Plastic injection molding – Ensuring reliable ejection of molded parts.
Die casting – Suitable for aluminum, zinc, and magnesium alloys.
Automotive molds – High precision and durability for complex parts.
Electronics & medical device molds – Where accuracy and surface finish are critical.

➤ Advantages of DIN 9861 D Pins

Longer service life due to hardened and coated materials.
Reduced downtime and maintenance in high-volume production.
Standardized dimensions make them easy to replace and source globally.
Cost-effective solution for improving mold efficiency.

➤Conclusion

DIN 9861 D ejector pins are a crucial mold component offering precision, strength, and durability. Their standardized design with a 60° conical head ensures stable performance in demanding injection molding and die casting applications. For manufacturers in automotive, electronics, packaging, and medical industries, DIN 9861 D ejector pins provide a reliable choice to improve production efficiency and extend mold lifespan.
