Most important factor of core pins is smooth continuous line, especially where a radius meets a straight line. Highly developed, sophisticated ingenuity of Dynamo guarantees smoothness. |

Water Cooling Hole The hole is concentric to the O.D. within 0.03mm(0.012") This prolongs pin life by providing equal cooling in all directions. |

To work on form pin pictures above, prepare two electrodes, finishing one for EDM with ±0.01mm(0.0004 inch) tolerance. After EDM, application of Magaria treatment takes off EDM scale, tough hard skin and leaves a metallurgical stableness necessary against erosion and deposit. |

Positioning pin hole

Flat for positioning

Self sealing pin (1) Controls flash direction
(2) Screw Inspected by first grade screw gauge

Erosion, deposit and solder resistant. Low thermal conductivity and adiabatic thereby making flow lines difficult to develop. Very light and anti-rust material. |
![]() |
Reduces erosion, deposit and soldering. Cooling efficiency is 4 times that of H13. This material is very difficult to machine. |

*After request, it will be manufactured. Our specially developed draw polish machine produces smooth symmetrical straight lines without any undercut which is usually caused during hard polish. Perfect for long draw hole of aluminum products. |
