After receiving a customer order Butler Winding will purchases the cores, bobbins, winding tubes, terminals, magnet wire, lead wire, and/or insulation needed to build the customer’s parts.  Then Butler Winding winds the coils; terminates the coil windings to pins, pads, terminals, or lead wires as required (including soldering and/or crimping); assembles (or stacks) the core(s) into the coils; tests the parts; bakes the parts if required; varnishes or encapsulates the parts; labels the parts; and then ships the parts.  Yes, Butler Winding also sends a bill for the parts to the customer.

Manufacturing can do any of the above processes as a “value added” process.  One of our customers sends transformers to Butler Winding to encapsulate (pot) in epoxy.  Manufacturing makes every reasonable effort to meet the customer’s delivery dates.

Manufacturing can vacuum impregnate varnishes and encapsulate (potting) under vacuum.  Manufacturing also has the capability to temperature cycle parts if needed.  Butler Winding has one coil winder capable of winding with single digit wire gauges.  For toroids #12 A.W.G. is the largest single conductor wire size our machines can handle.  Manufacturing equipment available for use includes:

• Tanac AX3 automated (programmable) winding machine.
