Spiral Groove Ejector Pins

Spiral Groove Ejector Pins are mainly used in a plastic, pressure casting mold, The function of these parts is to separate forming products from mould.
MATERIAL: SKD61
HARDNESS: 48-52HRC

The feature of spiral groove ejector pin:

1. It can prevent block due to thermal expansion from slide.
2. spiral groove effectively to exhaust air in core from mold.

Scope of application of spiral groove ejector pins：

1. Suitable for molds with a cavity temperature of 80-200°C;
2. Suitable for high-speed ejection, gap ejection mold;
3. Suitable for long maintenance time of molds, continuous forming unmanned operation, and precision forming in mass production.

Precautions:

Spiral groove ejector pins are not suitable for use in the high-gloss mirror and transparent product molds.
