This isa high-strength steel that has the physicalproperties needed to withstand thecontinuous punishment – the friction, the thermal andmechanical stresses – of plastics molding and die casting.Reason No. 2D-M-E has developed its own technology for hot-forging and some of its ownextremely sophisticated equipment. Totally automatic, this equipment controlstemperatures closely within 9°F (5°C), a major factor in producing uniform grainflow in D-M-E Ejector Pins and Sleeves and Core Pins, and in increasing theirdensity and tensile strength.Reason No. 3To give the strongest bond between the hard surface case and tough core,D-M-E uses a “new generation” nitriding process. Automated equipment monitorsand controls temperatures, processing time, and the ammonia atmosphere closelyand continuously – the only way to produce ejector pins and sleeves with highsurface hardness and good, tough cores.Reason No. 4After they’re finish ground and nitrided, D-M-E Ejector Pins and Sleeves aresent through an extra surface finishing operation. This gives them an exceptionallysmooth surface finish which greatly reduces friction and wear that can causetroublesome flash in ejector pin holes.Reason No. 5In addition to in-process inspections for surface hardness, case depth (ejector pinsonly), surface finish, and radius under the head, D-M-E checks and double checksits ejector and core pins for dimensional accuracy, concentricity and straightness.Reason No. 6D-M-E has the world’s most complete line of standard pins and sleeves – in stock –ready for immediate delivery to you.

This alloy provides severaladvantages, including better conductivity, increased strength,reduced wear and resistance to rusting. Performance CorePins are ideal for use in high-volume applications where partquality, fit and finish are critical.Reduced cycle timeIt is often difficult or expensive to adequately cool the areasurrounding the core pin in a mold, especially when moldingthick-walled parts. Depending on the design of the mold, itmay even be impossible to run water lines near the pin, thusgreatly increasing cycle times.The copper-based alloy used in Performance Core Pins cansignificantly reduce mold cycle times by increasing the rate ofheat transfer. The Performance Core Pin, when used in placeof traditional C- or CX-type pins, will provide up to 10 timesthe rate of heat transfer. Heat is transferred at twice the rateof pins made of a beryllium-copper alloy.In addition, the low-adhesion characteristics of the pins makepart ejection faster and easier. All of these advantages combineto reduce the overall cycle time and increase productivity.Improved part qualityThe excellent thermal diffusivity of the pins provide ahomogenous temperature profile throughout the core surface.Uniform temperatures result in reduced post-mold shrinkageand warpage, improving the quality of the part. Also, becauseof the low-adhesion characteristics of the pin, parts are notdamaged by adhesion to the pin during part ejection.Lower machining costsThe high thermal conductivity of Performance Core Pinsreduces the need for complex cooling designs that canrequire hours of additional machining. Plus, the pins requireno additional heat treatment and can be machined usingconventional methods or EDM.Longer service lifePerformance Core Pins have a high resistance to thermalstress, wear and abrasion. This assures long life undervirtually any molding conditions. With appropriate alterationto pin diameter, they can be used in conjunction with standardejector sleeves. The dissimilar metals and compatible coefficientof friction will reduce metal-to-metal pick up and wear.Wide range of sizesPerformance Core Pins are available in 21 pin diametersfrom 3/32- to 3/4- and 3-, 6-, 14- or 20-inch lengths.Typical MoldAs shown in the pie chart, mold cooling comprisesthe largest part of the mold cycle.
