Thermal Pins

Noren’s thermal pins are high-temperature heat pipes and are used in a variety of molding equipment – injection molding, blow molding, extrusion molding and thermal form molding industries.

Faster Plastic Mold Cooling: The ability to rapidly transfer heat at high volumes is essential to the molding process, and custom thermal pins give companies the capability to do so continuously and at minimal costs. The specialized heat pipes are custom-designed to fit into most common cores for injection, extrusion, rotational, and blow molding equipment. In addition to rapid heat transfer, thermal pins also provide isothermal cooling to increase yields as well as ensure optimal quality for every mold produced.

Custom-Designed Thermal Pins: Noren’s innovative thermal pin design is so simple and efficient that its cooling is advantageous for maintenance retrofits as well as OEM production applications. One thousand times more conductive than copper of the same weight, thermal pins conduct large volumes of thermal energy away from heat sources.

Noren offers different ways to use the Thermal Pin heat conductors – you can either insert the Thermal Pin into your existing core, or Noren can make your core into a thermal pin heat conductor by processing your cores at their manufacturing facility. The function of Noren’s thermal pin heat conductors is to remove heat very quickly which reduces cycle times resulting in increased yields.

Injection/Blow Molding:
In small cores, thermal pins enable cooling in areas previously 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. 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.

Extrusion/Rotational Molding:
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. Thermal pin heat conductors transfer heat from rotational and rubber molds to heat the plastic more quickly and evenly, regardless of variations in mold thickness.
