N N Engineering boasts of being the best step ejector pin manufacturers and suppliers in Pune. After a long time of working in the sphere of precision tooling, we have decided to offer the high-quality products and meet the strict demands of the modern injection moulding industries. We have combined premium manufacturing with premium quality.
An ejector pin with this particular fitting is known as Step Ejector Pin. It is a reduced diameter or stepped section all the way along its length (compared to a normal pin). This design allows it to spill out fine or thin sections of a moulded part in a liquid state and minimize stress levels, harm and retain small detail. Complex shaped, or delicate, moulds need Step Ejector Pin to ensure high quality and uniformity of moulded products.
Types of Step Ejector Pin:
As one of the experienced step ejector pin suppliers in Pune, we are offering the best quality step ejector pin.
- Types by Design
- Straight Step Ejector Pin: This is a common design, a step is incorporated in the design to create a point of contact to eject.
- Shoulder Step Ejector Pin: This type of pin is identical to a straight pin except it has a larger diameter shoulder giving it more contact area and a higher concentration of force.
- Sleeve Step Ejector Pin: This is a variant in which a sleeve is placed around a core pin, giving it a larger ejection area and avoiding part damage.
- Blade Step Ejector Pin: Designed to eject certain features or thin spots in order to create a thin, flat point of contact.
- Double Step Ejector Pin: Step ejector pin manufacturers in Pune has two steps in the design to meet certain application requirements.
- Material and Treatment
- Nitrided Step Ejector Pins: Nitrided to give them high durability, wear resistance and high-temperature usage.
- Stainless Steel Step Ejector Pins: Constructed of non-corrosive stainless steel, which is applicable in multiple heavy-duty applications.
- Hot Die Steel (HDS) Step Ejector Pins: Cast with a special hot die steel which is highly strong and is resistant to the heat and pressure of the molding process.
