An apparatus and process for manufacturing insulation for metallic rod which includes a mechanism for housing a plurality of ingredients, scales for weighing a predetermined quantity of each ingredient, a blender for blending predetermined amounts of each ingredient into one material, a mixer to mix the dry blend of ingredients, a mill to form the blended material into strips, a dicer to transform the strips into pellets of insulation, an extruder for placing insulation around the metallic rod, a conveyor to transport the ingredients and/or material between each of the above steps, a controller for outputting commands to the blender and receiving inputs from the scales to obtain the predetermined amount of each ingredient, and a computer for verifying that the correct amount of each ingredient has been obtained. The ingredients used in the manufacture of this insulation material include plasticizers, fillers, a resin, and modifiers. In the step of obtaining the correct weight of each ingredient, the controller employs multiple setpoints to gradually obtain the required ingredient weight through what is known as a dribble feed function.
