Stepped Ejector Pins

Stepped ejector pins are mainly used in a plastic, pressure casting mold, The function of these parts is to separate forming products from mould.
MATERIAL: SKH51
HARDNESS: 58-62HRC
COATING: TiN

TiN coating ejector pin feature:

1. The advantage of Tin coating is high hardness, small friction coefficient, to help enhance productivity and products quality.
2. Improve corrosion resistance, Such as engineering plastics when shaping to produce air Tin coating can prevent ejector pin from air corrosion resistance.

Recommend the use of occasions:

1. Fast cycle shaping or ask long service life mould
2. Can’t apply to this mould with lubricating oil
3. Usage this material of mould easy to produce air( engineering plastics, including the fiberglass resin)
4. Ejector pin easy wear and tear to this mould.
5. Request this mould for high wear resistance, release, corrosion resistance.
