Who We Are

Built for Durability and Precision Color Matching

Our powder coating services support product teams and manufacturers who need protective, professional finishes without managing their own coating line. From single prototypes to production batches, we coat brackets, panels, enclosures, chassis, frames, and finished assemblies using electrostatic spray application, controlled pre-treatment, and calibrated cure cycles that deliver consistent adhesion, film thickness, and color across every part.

Our Process

From Bare Metal to Finished Coating in Five Steps

A structured coating process designed to deliver durable, consistent finishes with full traceability and no surprises between quote and final inspection.

01

Submit Your Parts

Send CAD files, samples, or finished parts with color specification (RAL, Pantone, or sample), finish type (gloss, matte, textured), quantity, and application requirements. We review substrate material, geometry, and masking needs.

02

Color Matching & Sample Approval

Custom colors are formulated and verified through spectrophotometry. Sample panels are coated and cured to specification, then shipped for approval before production coating begins, ensuring exact color and finish match.

03

Surface Preparation & Masking

Parts are cleaned prior to coating. Threads, holes, and critical surfaces are masked with high-temperature plugs and fixtures.

04

Electrostatic Application & Curing

Thermosetting powder is applied via electrostatic spray with controlled film thickness. Parts enter the convection oven where calibrated cure cycles achieve crosslinking, flow-out, and peak metal temperature per powder manufacturer specifications.

05

Inspection & Delivery

Film thickness is measured with mil gauges, adhesion is verified through cross-hatch testing per ASTM D3359, and visual inspection confirms uniform coverage and color. Parts ship with coating certifications and full traceability documentation.

Why Cusack Electronics

What Sets Our Powder Coating Services Apart

The advantages of working with a coating shop that treats powder coating as part of a complete product development and manufacturing workflow, not a standalone finishing service.

Same-Day Turnaround Available

Rush powder coating services deliver single parts and small batches in 24 to 48 hours. Standard production runs ship in 3 to 5 business days with no minimum order quantities, supporting tight timelines without premium pricing.

Custom Color Matching Expertise

Our spectrophotometry system formulates custom colors to exact RAL, Pantone, or sample specifications with delta E verification. Metallic, candy, and textured finishes are dialed in before production coating to eliminate rework and delays.

Prototype to Production Continuity

Start with sample coating and color approval, refine the finish, then scale directly into low-volume or high-volume production with the same powder formulation, cure cycle, and quality standards already validated.

Integrated Manufacturing Workflow

Powder coating services integrate with CNC machining, wire harness assembly, UV printing, and full product assembly in the same facility, eliminating shipping damage, finish contamination, and handoff delays between vendors.

No Outgassing or Blistering

Pre-treatment protocols and controlled cure cycles prevent outgassing, blistering, and adhesion failure on castings, welded assemblies, and porous substrates. Parts are inspected before coating to catch surface defects early.

Full Testing & Documentation

Film thickness measurement, cross-hatch adhesion testing per ASTM D3359, impact testing per ASTM D2794, and salt spray testing per ASTM B117 are available on request with certificates of conformance supporting ISO and customer-specific quality systems.

Common Questions

Frequently Asked Questions

What powder coating services do you offer?

We offer electrostatic spray powder coating for metal parts and assemblies using thermosetting epoxy, polyester, polyurethane, and hybrid powder formulations. Our custom powder coating services cover gloss, matte, textured, metallic, and wrinkle finishes with custom color matching to RAL, Pantone, or sample.

Aluminum, steel, stainless steel, galvanized steel, cold-rolled steel, hot-rolled steel, cast iron, zinc-plated parts, and MDF (medium-density fiberboard). Non-conductive substrates require special pre-treatment or alternative coating methods.

Powder coating delivers superior impact resistance, abrasion resistance, corrosion resistance, and UV resistance compared to wet paint. Thermosetting powder crosslinks during the cure cycle, creating a harder, more chemically bonded film that resists chipping, fading, and chemical exposure.

We stock 1000+ standard RAL colors and can custom-match any Pantone, RAL, or physical sample. Finish options include high-gloss, semi-gloss, matte, textured, metallic, candy, wrinkle, hammer tone, and clear coat with gloss levels from 5 to 95 GU.

Yes. Our spectrophotometry system formulates custom colors with delta E verification to ensure exact match. Sample panels are coated and shipped for approval before production coating begins, eliminating color variation and rework.

What is your lead time for powder coating?

Rush service delivers single parts and small batches in 24 to 48 hours. Standard production runs (10 to 100 pieces) ship in 3 to 5 business days. High-volume production is quoted based on quantity, masking complexity, and cure schedule.

Yes. We mask threads, holes, mating surfaces, grounding paths, and critical dimensions using high-temperature silicone plugs, tapes, and custom fixtures. Selective coating protects areas requiring bare metal contact or post-coating machining.

Film thickness measurement, cross-hatch adhesion testing per ASTM D3359, impact testing per ASTM D2794, salt spray testing per ASTM B117, and hardness testing per ASTM D3363. Certificates of conformance support AAMA 2603, AAMA 2604, AAMA 2605, Qualicoat, and customer-specific quality requirements.

Yes. Every part is sandblasted or media blasted to remove oils, oxides, and contaminants, then treated with iron phosphate or zinc phosphate conversion coating to promote adhesion and corrosion resistance. Pre-treatment is included in our powder coating services.

Yes. Parts move from CNC machining, wire harness assembly, or product assembly directly into our powder booth without leaving the facility. Integrated workflow eliminates shipping damage, finish contamination, and vendor coordination while compressing lead times.
