The inner diameter processing of sleeve pins, primarily using gun drilling, is also playing a significant role in the machining of cooling holes in castings!
The "Ejector Pin" is a precision metal part capable of processing cooling holes and cooling holes for jet cooling. For narrow cooling holes, we use a hole drilling electrical discharge machine for processing. We can also process jet cooling holes with a diameter of Φ2 and a depth of 250. Additionally, if necessary, we can accommodate vertical polishing to enhance release properties through PVD, PCVD coating, TD treatment, and DLC treatment. If you have any concerns regarding the lifespan of ejector pins, please feel free to consult us. 【Features】 ■ Capable of processing cooling holes and cooling holes for jet cooling ■ Uses a hole drilling electrical discharge machine for narrow cooling holes ■ Can process jet cooling holes with a diameter of Φ2 and a depth of 250 ■ Careful attention is paid to the SR part at the end to prevent cracks ■ Supports various coatings *For more details, please refer to the PDF document or feel free to contact us.
