Good Reasons to Use Thermal Pin™ Heat Conductors

Cool Molds Fast to Reduce Cycle Time

Because THERMAL PIN heat conductors always transfer heat toward the cooler end. In small cores, you can cool to a water channel in areas that had previously been inaccessible to water cooling. In solid cores, you can draw heat from the plastic to the mold base or to remote water channels. Most solid core applications pay for themselves in 4 to 12 weeks (Application and installation literature is available.) In blow molding, the hollow THERMAL PIN heat conductor uniformly cools the end of the blow pin. Hollow THERMAL PIN heat conductors evenly cool the necks of blow molded bottles. (Ask us for literature on blow molding and other applications). In your mold cooling applications, see our THERMAL PIN heat conductor DESIGN GUIDE on the facing page to see if you can reduce your cycle time.

Level Hot Spots to Improve Part Quality

Because THERMAL PIN heat conductors are virtually isothermal, not only do they transfer heat fast, they do it evenly. They eliminate hot spots which cause sink marks, pulling, and spotting.

Give You Remote Cooling to Fix Damaged Molds

THERMAL PIN heat conductors transfer heat to the coolant. You can now isolate the coolant from mold components which have problems with seepage or leaks.

Eliminate Scale and Plugging to Reduce Maintenance Costs

Scale often plugs up the small-diameter water channels going into the core. You don't need these narrow water channels when you use THERMAL PIN heat conductors.

Eliminate Water Lines to Reduce Tooling Costs

Rather than use a bubbler, which requires two sets of water lines, use THERMAL PIN heat conductors which need only one.

Transfer Heat Where You Need It to Reduce Cycle Time On Thermosets

For example, finned THERMAL PIN heat conductors transfer heat into rotational molds to heat the plastic more quickly and more evenly, regardless of variations in mold thickness.

The THERMAL PIN Heat Conductor is not an Ordinary Heat Pipe

Noren Products, Inc., has taken heat pipe concepts and adapted them to cool plastic molds. Traditionally, heat pipes have been used to transfer a steady heat load. More than a decade ago, we designed THERMAL PIN heat conductors (TPhc's™) to function under cyclic heat loads like those encountered in injection molding, blow molding, and other plastics processing. The modifications we made are, of course, proprietary.
