1. A mold straight ejector pin is a simple, cylindrical steel shaft used in injection molding to push cooled plastic or rubber parts out of the mold cavity. 2. Material: SKD61 3. Hardness : 48-52 HRC 4. Simple Geometry: Uniform cylindrical shaft without any stepped or tapered changes in diameter. 5.Standardization: Highly standardized in the industry, making them incredibly easy to replace and maintain, which minimizes production downtime.

Application : 1.Standard Plastic Parts: Best suited for parts with a simple, uniform design, minimal undercuts, and consistent wall thicknesses. 2.Mass Production: Frequently used in conventional, multi-cavity injection molds for high-volume manufacturing. 3.Shallow Draft Angles: Used where the part design easily releases from the core plate without the need for specialized, contoured, or stepped pins.

Key Features of Ejector Sleeve Pins : 1. Hollow Design: Fits over a core pin (or mandrel) within the mold, allowing it to push the part edge without interfering with the internal diameter, as explained in. 2.Uniform Force Distribution: Unlike standard round pins, sleeves distribute force around the entire circumference of a, say, circular boss, minimizing the risk of tearing or breaking the plastic part. 3.Material and Hardening: Usually manufactured from high-performance materials like H13 steel (hardened to 48-55 HRC) or SKD61 stainless steel for corrosion resistance, ensuring long-lasting performance under high-pressure conditions. 4.Surface Treatments: Available with DLC (Diamond-Like Carbon) coatings to reduce friction (coefficient 0.1-0.15), enhancing wear resistance and reducing sticking in clean room or medical applications. 5.Minimal Cosmetic Impact: By pushing on the base of a boss, the "witness marks" or pin marks are often hidden, which is crucial for high-quality finished products. Application : Ejector sleeves are primarily used in plastic injection molding for specific part geometries that are prone to sticking or damage. 1. Cylindrical Bosses and Ribs: Ideal for ejecting cylindrical parts with thin walls. 2.Deep Cylindrical Features: Used in projects requiring high-precision removal of hollow, tube-like parts. 3.Sticky Resins: Beneficial for materials that adhere strongly to the core, as the 360-degree force reduces sticking, as shown in. 4.Medical and Precision Parts: Often used in cleanroom molding due to their ability to be treated with friction-reducing coatings. 5.Typical Example: Used to eject plastic caps, threaded parts, and gear assemblies where the entire edge needs to be pushed.

A flat ejector pin (or ejector blade) features a rectangular or flat-topped cross-section. It is specifically designed to push molded parts out of an injection mold in tight or angular spaces—like deep ribs, thin walls, or core details—where standard round pins are too wide or would cause surface damage. Features : 1. Rectangular Profile: Provides a larger, flat surface area to push on, distributing the ejection force more evenly over narrow sections of the part. 2.Specialized Materials: Typically manufactured using through-hardened or nitrided tool steels (like SKD61) to handle the extreme pressure and sliding friction of high-volume molding. 3.Custom Fit: Often machined via wire electrical discharge machining (EDM) to fit precisely at the bottom of deep product ribs without interfering with the mold cavity. Application : 1.Deep Ribs & Bosses: Ideal for ejecting tall, narrow structural ribs that would otherwise stick tightly to the mold wall. 2.Thin-Walled Sections: Distributes force across weak, thin areas to prevent the pin from punching through or cracking the plastic part during ejection. 3.Component-Specific Ejection: Used when part geometry restricts the use of standard round pins (such as on angular edges or flat stepped surfaces).
