Filling center

The filling center is made up of three types of machines produced by CSM MACHINERY: the tube presetter, the filling machine and the plug up unit.

These machines are placed side by side, thus allowing a continuous cycle that makes the most of both the level of automation and the advantages of the individual machines. For this reason, only one operator is sufficient to manage the filling center.

The cycle in the filling center consists of a series of repeating steps:

• Preparation of the tubes with the automatic tube presetter thus they are ready to be transferred in the filling machine.
• Loading of tubes in the filling machine in order to be filled with the magnesium oxide (MgO).
• After the filling cycle, loading of the tubes in the plug up unit for the assembly of the plastic plug on the top terminal pin of the filled heating elements.

 The repetition of these steps depends on customer's production needs. 

Depending on customer needs, the filling centre can be completed with the roll reducing mill including the automatic feeder and the automatic unloading device. Doing this, in a filling centre is not only possible to fill with MgO heating elements and to mount the upper plug but it is also possible to reduce the diameter of the filled heating elements. Despite the addition of the roll reducing mill, only one operator is still necessary.

In both cases, the main advantages of the filling centre are:

• The need of only one operator to set and manage the machines.
• The possibility to make the most of the automation systems of the machines.
• The reduction of time production processes without losing the quality of the final product.
• The production of up to 600 tubes per hour 

Tube presetter

The tube presetter prepares all the tubes that have to be filled with magnesium oxide (MgO). By doing this, using the appropriate clamp, the tubes are ready to be moved all at once to the filling machine.

In the automatic version, it is the device that autonomously arranges the tubes. Moreover, the hopper-like feeder of the automatic tube presetter has a capacity of 200 tubes and the length of tubes loaded into the presetter shall be between 260 mm and 2000 mm.

Both the automatic version and the manual one can load 30 tubes or 24 tubes.

Filling machine

The filling machine for double-side heating elements is used to fill heating elements with magnesium oxide (MgO) in such a way that they can be processed in the subsequent production stages.

CSM filling machines can fill up to 30 tubes, instead of the traditional 24.

Moreover, the filling MgO for heating elements can fill tubes ranging from 7.5 millimetres up to 19 millimetres with patented system for MgO flow control for greater filling speeds and leak elimination. The electromechanical vibration system guarantee a uniform MgO compaction.

Plug up unit 

The plug up unit is a device that automatically assemble the plastic plug onto the upper terminal pin of the filled heating element. This is an essential step in order to prevent the magnesium oxide from flowing out. 

Once the operator loads the filled heating elements into the machine, the plug up unit starts working autonomously.

Roll reducing mill with automatic feeder and unloading device

The roll reducing mill reduces the diameter of filled heating elements, increasing the internal compaction of the magnesium oxide. This step is fundamental for the subsequent production processes. 

The rolling mill is equipped with high-quality rolls of same diameter and rotation speed in either tool steel or tungsten carbide.

To enlarge the automation of the machine it is possible to integrate the automatic feeder and the unloading device. The first one ensures a constant feed by automatically introducing heating elements into the roll reducing mill; the second one collects the heating elements exiting the rolling mill and conveys them to a container.
