MOLD COOLING Heat Pipes - Cooling Pins
Reduce Maintenance and Operating Costs The increased waterline diameter, coolant velocity and heat capacity effectively eliminate scale formation, calcium deposits and the plugging up of small waterlines and ports. In addition, Heat Pipes operate in any coolant without corroding. Upgrade Existing Molds and Dies Heat Pipes effectively solve cooling, cycle time or part quality problems in existing molds. They can be retrofitted as replacements for bubblers or baffles and to provide heat transfer in previously uncooled areas. Salvage Damaged Molds and Dies In certain applications, Heat Pipes can even be used to salvage or repair molds that would otherwise have to be scrapped or extensively reworked.
TPL and TPH heat pipes for injection molding For low-temperature Heat Pipes (40˚-200˚F) use TPL (color- coded BLACK) as a prefix in front of item number in the chart below. For high-temperature Heat Pipes (150˚-400˚F) use TPH (color-coded WHITE) as the prefix. Examples: TPL8600; TPH6500.

Silver heat transfer compound* – HTC06S
ITEM NUMBER HTC06S
A
Contains micronic particles of silver to provide a thermal resistance of 4.75°C
in/watt. The compound is supplied in a 5cc plastic syringe. (DME recommends the Silver Heat Transfer Compound because it has eight times lower thermal resistance than the copper equivalent.) Copper heat transfer compound* – HTC30C
.125'' MIN
TAMP RINGS
“O” RINGS
Selecting the right size and shape The standard diameters and lengths of TPL and TPH Series Heat Pipes will satisfy most applications.
Contains micronic particles of copper to provide a thermal resistance of 38°C in/watt. The compound is supplied in a 5cc plastic syringe.

Length ±.020 NOTE: Heat Pipes cannot be used as ejector pins and parts cannot be molded or cast against them. Also, Heat Pipes cannot be cut, machined, bent or plated. If a special size is required, contact DME to discuss your application.
* For .125" diameter Heat Pipes, do not use applicator tube supplied with Heat Transfer Compound. Apply desired amount of compound directly into core hole.
Tamp ring sets – TARS Each set includes 32 silver alloy tamp rings (enough for installing 16 Heat Pipes) and one hollow tamping tube. Select the required tamp ring set by its I.D. to match the O.D. of the Heat Pipe being used.
