Fluidize / Bed Coating

We offer hot-dipping powder coating using a variety of electrical resins, including 3M 260, 262, 263, 5230N, and others.

Hot dipping provides several advantages, including a controlled environment with homogeneous surfaces as well as better finish and overall appearance.

Thickness ranges from a few mils up to 0.030” (or more depending on specific material), with high precision for critical applications. Custom masking and post-machining are also offered for complex or tight geometries.

Compatible components include laminated stack/cores, stators, rotors, aluminum parts, steel parts, etc.

Painting/Coating

General coatings are also offered at Windtech, such as primers, anticorrosion and dielectric protection materials. Our experience includes air-dry and oven-cured coatings. Our team works with most paints, can/spray materials and air-pressurized coatings.

Dedicated booths to avoid cross-contamination available for critical applications.

Highly skilled personnel to ensure production consistency; thin-layer coatings up to 0.0003” thick (for special applications).

100% dimensional and visual inspection to ensure quality.

 

Welding Types

Windtech offers a wide variety of welding options. A few applications include laminated-core welding, induction rotors (copper or aluminum), winding connections (lead-wires, WYE, busbars, etc.) and custom parts.
