Cable Molds
We design and machine two different types of molds for use in our vulcanizers. Molds are CNC machined from 6061 aluminum. All CV molds are fitted with hardened pins and bushings for alignment.
Splicing molds are used to join two cables together or repair damaged wires within a multi-conductor cable.
Splicing molds open up to a larger diameter in the center of the mold to accommodate the extra space required for the splice.
Repair molds are used to repair damaged outer jackets only. Repair molds have the same diameter of the cable being repaired all the way through the mold.
