Standard Heat Pipes
The PIPCAR Heat Pipe is the ideal way to cool cores. It ensures optimum moulded component quality. It also maximises productivity by minimising both cycle times and tool down time resulting from blocked waterways. It simplifies tool design and construction thereby reducing costs. It is available in a wide range of standard sizes - see table 1. Non-standard sizes can also be readily supplied.

Application
Figure 1 shows a typical installation.
In general, the largest possible diameter Heat Pipe should be chosen that can be accommodated without unduly weakening the core. The core should be drilled out to the nominal Heat Pipe size plus 0.1mm. Our Therma-Grease should then be used during installation of the Heat Pipe to fill the radial gap and improve heat transfer.
We recommend that a minimum of 20% of the heated length should be in contact with the cooling water. Please note, however, that many applications using less than this recommended minimum have been successful.
Temperature Ranges
The standard range (STD) operates from +5oC to +250oC (Heat Pipe temperature) and is suitable for use with nearly all plastics.
The low temperature range (LT) operates between -40oC and +125oC (Heat Pipe temperature) and should only be used when cooling with chilled water below +5oC
Materials
Both ranges are made from electroless nickel plated high conductivity copper to BS2871 C106 (ISO-CU-DHP).
Tolerances
Diameter: +0.00mm/-0.10mm.
Length: +0.00/-0.50mm.
Ordering
CP1000 - diameter x length / temperature range.
E.g. CP1000 4.0 x 125/ STD
Imperial size Heat Pipe
PIPCAR also make Heat Pipes in a large range of imperial diameters and lengths

Temperature Ranges
The standard range (STD) operates from +40oF to +480oF (Heat Pipe temperature) and is suitable for use with nearly all plastics.
The low temperature range (LT) operates between -40oF and +260oF (Heat Pipe temperature) and should only be used when cooling with chilled water below +40oF
Materials
Both ranges are made from electroless nickel plated high conductivity copper to BS2871 C106 (ISO-CU-DHP).
Tolerances
Diameter: +0.000”/-0.005”.
Length: +0.00/-0.020”
Ordering
CP - diameter x length / temperature range.
E.g. CP 1/8 x 4 / STD
