By using Expan Maxiwatt cartridge heaters, you can operate your process with less downtime, higher efficiency, faster production times and more uniform heating.
The expandable cartridge Heaters solve two major problems with conventional high density heaters, poor durability and proper fit extraction, improving the accuracy of the temperature with hundreds of attachments and exits for all kind of processes.
With the expandable cartridge heaters we join for the first time the best of the common cartridge heater with a cartridge and an adaptive tuning quick and easy removal.
The Expandable Heaters are made with just one heating wire spring shaped that has more quantity of wire than any other model of cartridge heater. We obtain, this way, a uniform heating throughout the whole perimeter, with no kinds of cold areas or with different temperatures.
The Expandable Heaters consist of a compressed cartridge heater a high performance and made with the best materials with the particularity of being able to expand itself because of the fork-shaped tensioned in a point that allows the expansion and retraction of the cartridge heater.
At the contraction process the Expandable Heaters returns to its original shape, helping for easy removal of the bore, with the subsequent advantages like not having to drill the mold, reuse them in other locations, reducing the stock since it will have the same diameter for different bores, etc.
In the expansion process the expandable cartridge fits the walls the bore, providing the correct transference of the temperature, and avoiding the “oven effect” that occurs in other types of cartridge poorly dimensioned with respect to diameter and room. The drills that for any other circumstances are oversized have the best solution to allow more adjustament tolerance.
More Nickel/Chrome 80/20 heating wire at the Expandable Heaters than in a bipartite heater or a compressed cartridge heater with the same compression. The Expandable Heater has more heating wire (nickel / chromium80/20) than the bipartite heaters or compressed cartridges with the same compression. The main key is the more heating wire, the larger diameter for the sameamount of watts. The larger diameter reduces fatigue and use of the heating wire, resulting into a longer service life.
Expandable heaters will not bend, which is the main problem with conventional cartridges, due to the shape of its tubes which perform the function to reinforce the structure of expandable heaters longitudinally, helping for its removal, by expanding equally throughout the perimeter, heat transference will be uniform not creating curvatures which produce cavities resulting overheat breaking the heater.
Compressed Cartridge heaters
Split Sheath Expan
Expandable heaters, for its unique construction, allow the easy removal when the cartridge is cold saving time and considerable effort, minimizing the time that the machine is stopped and human resources. Needs no adjustment paste and you will not have to drill, destroy or undertake the costly operations to remove the cartridge, you can quickly use the Expandable Heaters in other moulds that need heating.
Please note that you must provide us with exact hole diameter in order to start EXPAN production with the right tolerance. It is important to get harmony between the hole and heating element for a perfect working. Tolerance for EXPAN heaters is -0,0039” / -0,006”. For example, if the hole you will insert the EXPAN element is Ø 1/2” we will produce the split elements between 0,496” – 0,494”. You must inform us about the exact diameter for the hole you will place the heater and we will produce with the right tolerance.
The expansion around the perimeter of the cartridge make of the Expandable Heater the best solution for large diameter holes, wear and tear caused by expansion or not made to very close tolerances.
Maximum adjustment Better heat transfer Adjustment toleranceThe adjustment tolerance of the heater is called the distance obtained between the surface of the cartridge and the inner wall of the hole, which must be uniform throughout its lineal perimeter.
Clearly shows the absence of cold zones due to its unique construction, which allows more heating wire in the whole area of the cartridge included in the connection areas.
It is observed cold spots at the end of the connections. This does not uniformly heated mould or application.
It is observed various cold areas, especially in the center of the heater from 250mm.
Intermediate sizes can be made in diameter and length, voltage, watt distribution, cold zones, special attachments, exits, etc.

The cartridge heater can be made with a built in sensor, at any position of the heater as customer request. The advantages of incorporating sensors are countless, for example long life durability, localized temperature accuracy, energy saving, where you cannot accommodate a conventional sensor due to room problems.See thermocouples
The Expandable Heaters are manufactured with an internal compacting system of all its components in order to increase their lifetime. The Nickel/Chrome 80/20 conductor wire is introduced into the cavities of a ceramic core which focuses the suitable separation in order to obtain a better isolation. Fully coated with magnesium oxide of high purity grain sized controlled to ensure the complete cartridge Expan filed. Later a compacting process and surface rectification until calibrated the desired size. Finally, a rigorous quality control that guarantees the best performance of the cartridge.
