Alongside its solutions for double-sided tubular heating elements, Oakley Industrial Machinery also manufactures advanced filling machines for heating elements, specifically designed for cartridge heating elements and monotube heating elements.
A monotube heating element consists of two wound wires positioned side by side inside a steel tube and insulated with magnesium oxide (MgO). The OIM filling machine for monotube heating elements is engineered to handle this structure, efficiently filling tubes that have one closed end and an open end where two or more terminal pins are inserted.
The concrete advantages that make the difference
New-patented 3-tube system for MgO flow control, which allows for greater filling speeds. The system is fitted with a mechanical closing/opening device that allows higher MgO flow rates and keeps it from flowing, once closed.
The electromechanical vibration system, delivers stable and symmetrical oscillations across all vibration frequencies and operators can easily set different vibration levels. During filling, a travelling vibrator moves from the bottom to the top of the tube, ensuring uniform MgO compaction. After filling, the machine can keep the upper section of the heating element vibrating to further improve powder compaction in that area.
Motorized set up when changing the length of the tubes to be filled. Motorized adjustment of the top terminal pin protrusion from the tubes after being filled.
Two pairs of facilitate fixing the filling machine to the wall.
A simple and intuitive operator interface facilitates more intuitive operation and allows for quick setting and control of the main machine functions.
An encoder monitors the vibrator group’s position, stopping the carriage at a precise point when the tubes reach the bottom. This prevents the pins from colliding with the lower bar and allows the use of special plugs, such as pull-type plugs.

UPPER HOPPER
The hopper is designed to contain magnesium oxide (MgO) for insertion into the tubes.
TUBE CRIMPING GROUP
Hydraulic tube pressing unit to lock the inner coil in place.
CONTROL PANEL
The operator interface is simple and intuitive, enabling straightforward operation and allowing quick setting and control of all main machine functions.
FILLING SET
New patented 3-tube system for MgO flow control, allowing for higher filling speeds. The system is fitted with a mechanical opening/closing device that not only increases MgO flow rates, but also prevents MgO from flowing once closed.
TANK MOTORIZATION
Motorized adjustment when changing the length of the tubes to be filled. Motorized adjustment of the top terminal pin protrusion from the tubes after filling.
MOVING HOPPER
Working hopper that travels together with the filling set.
ADJUSTABLE BOTTOM BAR FOR TUBE SUPPORT
The position of the bottom bar is easily adjusted from the panel to accommodate different tube lengths.
VIBRATION GROUP
Electromechanical vibration system driven by a DC motor. The system delivers stable, symmetrical oscillations even when the vibration frequency is varied. Different vibration frequencies can be achieved by adjusting the motor speed. The traveling vibrator moves from the bottom to the top of the tube during the filling process.
