Case 29 - Hot Melt – Cable Fill

Type of User:

Copper or fiber optic cable manufacturer

Application:

Multiple strands of wire are twisted together (typically around a center core) to form a cable.  The cable then passes through a die where it is filled with a sealant or waterproof material.  The cable fill material is pumped from a 55-gallon drum into the die.  Some customers require flow control tied to the line speed of the cable machine.

Material Used:

Hot melt cable fill material manufactured by companies such as Cas Chem, Unigel, National Starch, and Henkel

Equipment/Solution:

Configured TOF 200 with heated fluid hose and automatic heated dispense valve.

Gear Pump Metering Unit with variable flow control.

Options for flow control are the air-operated mastic regulator or the heated PrecisionFlo LT. 

Either option requires an electric signal from the line to control the regulator, the PrecisionFlo LT, or the Gear Metering Unit.
