TM-50 Trickle Impregnating Machine


The Broomfield TM-50 trickle impregnating machine is designed to apply resins or coatings to small motor armatures and other products.

The operator is responsible for simply loading and unloading parts. The machine is automatically controlled by a programmable logic controller (PLC) that provides for multiple program storage.

The machine status and set up information is displayed on a terminal. Program changes can be easily made in response to menu-driven prompting.


The Broomfield TM-50 trickle impregnation machine features a rotary table with collets to hold 32 armatures. These collets are machine tool grade to ensure that the armatures are held firmly for accurate positioning. In its standard configuration, the machine has one trickle station with dual applicator tubes positional along the armature axis.

During a typical machine cycle, a door automatically opens when the machine is ready to be loaded. The armature then goes into the Preheat Oven which raises the temperature of the part for proper resin application. This temperature may be displayed in either Celsius or Fahrenheit.

After heating, the temperature of the armature is automatically measured. If the part is not at the correct temperature, no coating is applied. This operation also senses if no part is present. In either case, the machine remembers the location of the empty or bad part and turns on a reject part light when that part is ready to be unloaded. After the part is trickled, the resin cures as it indexes toward the unload position where the door opens for removal.

The TM-50 may be configured with a cure oven for resins requiring additional heating after trickle application if required. The temperature of this oven is controlled independently from the Preheat Oven. Armatures are rotated during the preheat, trickle and cure operations to ensure an even distribution of the resin or coating.
