Hybrid Core Pin® - Ejector pin & Corepin
Features
Excellent durability
Three times the life span has been verified compared to the past.
Aluminum die casting is used under severe conditions such as high temperature, high speed, and high pressure. Our hybrid core pins are manufactured using YXR33, which has excellent high temperature strength characteristics in the tip (A) where the melt of aluminum or the like comes into contact, and DAC with excellent toughness (deflection and hard to break) in the pedestal portion (B). By joining two materials with different characteristics using friction welding, we have realized a core pin that is much less difficult to break than in the past.
Quality
Bonding surface strength
Our hybrid core pins have been proven not to break at the junction surface by repeated tensile tests.

Cost
Reduction of total maintenance costs
It can be expected to have a longer life of more than three times as long as conventional core pins. In addition, with the longer the core pin is extended, the mold maintenance time is reduced and productivity is improved.
Integrated production
Integrated production from materials
Compatible with cooling holes
Since it is an integrated production from material procurement to completion, it is possible to manufacture the pin of the standard according to the customer's demand. Cooling holes can also be manufactured. By applying a cooling hole, baking is reduced and longer life can be expected.
