The CSM filling machine for flat electrical heating elements is designed to fill oval tubes with magnesium oxide, ensuring precise compaction and perfect centering of the resistive wire.
Built on CSM MACHINERY’s proven filling technology, including the patented three-tube filling system and the electromechanical vibration system, the machine brings these established processes to a new generation of equipment capable of working oval tubes for flat and oval electrical heating elements, available in both through-pin and single-tube (one open end) versions.
The result: high-performance heating elements suited to high-temperature environments, used in the food, aerospace, chemical-pharmaceutical and energy sectors.
The concrete advantages that make the difference

The filling machine uses CSM’s tested oxide filling systems, adapted to the unconventional geometry of the oval tube. This ensures a quality standard equal to that of traditional tubular heating elements, with no compromise on process precision and reliability.

One machine, two production options: by simply changing the production cycle, the system switches between filling standard flat tubular heating elements and single-tube flat tubular heating elements. This flexibility helps optimize investment and adapt production to different market needs, without requiring separate dedicated machines.

Even in complex configurations with up to three output pins, the machine ensures perfect filling and uniform compaction of magnesium oxide on single-tube heating elements. The result is a resistive wire that stays consistently centered and a flat electrical heating element with reliable long-term performance.
The machine is designed to fill oval single-tube (or through-pin) tubular electrical heating elements with magnesium oxide, in a configuration of 10 tubes (Ø24.1×8.25 mm) or 15 tubes (Ø10.8×8.8 mm) per cycle. It is suited to manufacturers who need precision, repeatability and high productivity in the filling stage.
Precise, efficient filling
At the core of the machine is the magnesium oxide dispensing unit, designed for high filling speeds while keeping the process fully under control: dispensing opens and closes without material dispersion, for a clean, consistent result over time.
To optimize compaction, the machine can keep the upper part of the heating element in vibration at the end of filling, for an adjustable period, increasing filling density. The oxide-free space at the top of the tube is also adjustable, to suit different production specifications.
Electromechanical vibration system
Vibration is handled by an electromechanical system that maintains symmetrical, stable oscillation regardless of the set frequency. Movement is generated by a DC motor, whose rotation speed directly determines the vibration frequency, allowing fine, repeatable process control.
