The Wire Trough
Design Intent
The Wire Trough shares many of the same overall principles of operation that the Multipass does. Both are designs spawned from the wire and cable industry. But while both are basically temperature control units used to cool wire jacketing, the primary difference between the two devices is the manner by which they control/reduce jacket temperature.
The Multipass sprays temperature controlled water onto the jacketing of the wire inducing more of a mist. This approach is extremely efficient from a heat removal standpoint. The method by which the Wire Trough removes heat is much more primitive but still effective. The trough accepts the wire into its center and submerges the wire below a body of temperature-controlled water. The water is damned at the intersection of each trough section, typically every 10’, so that the water does not build up at one end. Each trough is plumbed to receive water supply and return piping and the devices are typically not provided with the cooling loop.
Design Variability
The Wire Trough is divided into 10 foot sections and can be constructed to fit the customer’s required spatial/heat extraction needs. There are three required components to the design with the remaining design elements variable and optional. Among the required components is the entrance or fill box. This is the portion of the trough nearest to the discharge of the extruder die. It takes in the wire from the extruder and mixes it with the cooled supply water, initiating the hardening process. The trough section, typically done in ten foot lengths and featuring a bolt on flange on opposing ends, is the next required section. The trough can be baren and simply hold water or it can feature spigots, drains, misters, hold downs, covered/not-covered, and many other features to enhance or modify the process to better suit the customer's needs. There are three basic formats by which the trough is referred to (Square Bottom, Vee Bottom, and Round Bottom) with each designation referring to the approximate shape of the trough’s cross section. The final required portion is the discharge box. This unit is nearly identical to the intake box but can be configured to feature a telescoping portion to provide additional cooling capacity to the unit.
