INCH PINS, SLEEVES, BLADES Core Pin Retainers

Core Pin R etainers

Precision made of superior quality thermal shock resisting hotwork die steel Hot-forged heads provide uniform grain flow, higher tensile strength Outside diameter nitrided to 65-74 HRC hardness and finished to minimize wear Centerless ground and polished outer diameter

DME Standard Core Pin Retainers offer better performance than a set screw and allow the core pin to float within the counter-bore. Conveniently machined in the same setup and location as the corresponding pin hole, Core Pin Retainers eliminate labor costs to make individual backup plates.

DuPont ™ Krytox ® TM7 grease is specifically designed for the lubrication of seg- mented molds, both electrically and steam-heated. This lubricant eliminates car- bon residue buildup on the molds associated with hydrocarbon and hydrocar- bon-based synthetic greases. It exhibits excellent adhesion, allowing the opera- tor to significantly increase production by extending lubrication intervals. The TM7 will not bleed out to the parting line due to high heat tolerance and will last in excess of 5000 cycles, based on average curing times, without relubrication. Krytox ® TM7 is a fluorinated grease with polytetrafluorethylene (PTFE) thicken- ers and selected additives. It has excellent thermal stability and load-carrying abilities. TM7 has a high degree of chemical inertness and extremely high hydro- lytic stability. Contact with boiling water or steam has no effect on this product, it will stay in the location it was applied, providing the best lubrication possible.
