What are Straight Ejector Pins?
Straight Ejector Pins are made of superior quality SKD61, thermal, shock-resisting hot-work die steel
Hot-forged heads provide uniform grain flow, higher tensile strength
Core hardness 40 HRC
Outside diameter nitrided to 50 HRC hardness and finished minimizing wear
Heads annealed for easy machining
Centerless ground D diameter
Injection mold components Straight Ejector Pins, mainly used in plastic, pressure casting mold. The function of these parts is to separate forming products from molds.

Straight Ejector Pins Application
1. In plastic molds, separating the product from the mold is also the most commonly used;
2. Carbide Ejector Pin, such as tungsten steel Ejector Pin, can be used to pass longer and thinner holes;
3. The Ejector Pin is also called the lifting-top. It is a conical metal round rod with a head that is assembled on a lathe or grinder to support the workpiece and make the workpiece rotate around it, but it is completely different from the Ejector Pin of the plastic mold accessories;
4. Plastic mold Ejector Pin can also be used inside the mold, it can play a stabilizing role, and is called an insert pin.
The types of plastic mold Ejector Pin include flat Ejector Pins, dome pin, Shoulder ejector pin, standard Straight Ejector Pins, non-standard Straight Ejector Pins, etc.
The materials of plastic mold Ejector Pins are SKH51, SKD61, SKD11, 65Mn, etc.
SKH51 thimble has better toughness than SKD61; SKD61 thimble can withstand a high temperature of 1600℃, and the surface of SKD61 Ejector Pin can improve the wear resistance of Ejector Pin after nitriding.
65Mn Ejector Pin is of poor quality, brittle, and easy to break. Some plastic molds are no longer assembled and used with 65Mn Ejector Pin.
The standard model of Straight Ejector Pins for lathe and grinder:
The standard for fixed thimble is GB/T9204.1-1988, and the standard for rotary Ejector Pin is JB/T3580-1998.
