What is a Large Part Powder Coater?
Choosing a large part powder coater requires more than finding a shop with a spray booth and curing oven. Part dimensions, weight, substrate, finish specifications, and order quantity must fit the shop’s equipment and production process. Comparing those requirements with a coater’s capacity can be difficult.
At AFUSA, we match the coating system and application method to the part’s substrate and operating conditions. Our equipment and production controls support the specified appearance and surface protection on oversized components. Read on to learn more about our large part powder coating services, powder options, assembly, storage, and shipping.
Why Large or Oversized Parts Are Hard To Coat
Most shops size their booths, ovens, and racks around their typical job size. A large or heavy part falls outside that range, and problems can show up in cleaning, application, or curing.
Common Failure Points On Large Components or Assemblies
There are several reasons why this happens:
- Oven and Booth Size: Spray booths, curing ovens, and overhead conveyors match a shop's usual part size. A part that exceeds the booth opening or the oven interior won't go through that line.
- Pretreatment Coverage: Pretreatment cleans the metal and adds a thin conversion coating under the powder. Weld seams and internal channels block the cleaning solution, so those spots carry powder over bare or contaminated metal.
- Film Coverage: Electrostatic spray guns charge the powder and pull it onto a grounded part. The charge pushes powder away from recessed and shadowed areas, so those surfaces often end up thin or bare.
- Cure Time: Curing sets the coating by holding the part in an oven at a target temperature. A heavy part absorbs oven heat slowly through its mass, so the coating reaches cure temperature late and the cycle runs long.
- Handling and Racking: Oversized parts need racks and hoists sized to their weight. The wrong equipment lets a part scrape a rack or another load, and that scrape can ruin a finish already applied.
How One Bad Part Multiplies Costs
A coating problem on a large part rarely stays contained to that one part. Rework means stripping and recoating the piece, and that piece has already used hours of oven time and material. Coating failures discovered during installation can trigger warranty claims and delay the project.
Quality Large Part Powder Coating Services From AFUSA
AT AFUSA, we provide large part powder coating services for oversized industrial components and high-volume orders. Our facility near Erie handles powder application, curing, and final inspection.
Facility and equipment: Our facility near Erie, Pennsylvania, covers 80,000 square feet. Large curing ovens, fluid bed equipment, and spray booths accommodate oversized components and production runs of hundreds or thousands of parts.
Large part experience: We have provided powder coating services since 1970. Our completed projects include pump systems for large fountains, municipal water treatment components, and an entire stadium’s seating.
Application methods: Two application methods let us match the process to your part instead of forcing your part through one line. Our fluid bed dip tanks lay thick epoxy films on complex shapes, and our electrostatic spray booths coat broad surfaces evenly.
Curing Capacity: Expansive curing ovens hold oversized parts at target temperature for the full cure cycle. Heavy components reach cure temperature completely, so the film sets hard across the piece.
Powder Selection: We stock epoxy and polyester powders from major manufacturers and match the chemistry to your part's exposure conditions. Potable water applications may require epoxy coatings certified to NSF/ANSI/CAN 61, while outdoor parts often use polyester formulations for color and gloss retention under UV exposure.
The Large Part Powder Coater Manufacturers Trust
Poor coverage or improper curing can force our customers to strip and recoat large components. Our process controls reduce that risk and help keep production orders on schedule.
Powder Coating Options for Large Parts
Powder coating selection depends on the substrate and operating environment. We also review finish requirements and applicable standards before recommending a system.
Project Requirements Determine Powder Coating Selection
- Epoxy powder coatings: Epoxy powder coatings provide strong chemical and corrosion resistance. Their limited UV resistance makes them better suited to indoor applications or parts protected from sunlight.
- Polyester powder coatings: Polyester powder coatings provide better UV stability than epoxy and retain color and sheen during exterior exposure. We use polyester on outdoor steel and aluminum parts such as architectural systems, stadium seating, and playground equipment.
- Hybrid powder coatings: We use epoxy-polyester hybrids on indoor products with moderate durability requirements. These formulations do not match pure epoxy for corrosion resistance or exterior polyester for UV stability.
- Wood grain powder coatings: Our Decoral process typically uses a polyurethane-based powder coat. Dye sublimation transfers the wood pattern into the cured coating on steel or aluminum substrates up to 24 feet long.
- Standards and finish requirements: Potable water projects may require an epoxy coating certified to NSF/ANSI/CAN 61. Architectural aluminum projects may require an AAMA 2604-compliant wood grain finish with specified color, gloss, texture, and film thickness.
Coating Selection Affects Part Performance
Powder coating systems respond differently to UV exposure, chemicals, moisture, and abrasion. The selected system must provide the specified appearance and corrosion protection for the intended service life.
Powder Coating With Assembly, Storage and Shipping
We can add assembly, packaging, storage, and shipping to a powder coating project. Customers can select the services required for their finished products.
Preparing Finished Parts for Delivery
- Product reassembly: Some products arrive as complete assemblies and need disassembly before coating. We reassemble the coated components before shipment or distribution.
- Secondary operations: Gasketing and hole tapping can be completed after coating. We can also label or stencil the finished products.
- Packaging: Packaging can include specified skids and shrink wrap. We can discuss other packaging requirements for each project.
- Inventory and storage: Finished parts can remain in temporary storage until pickup or shipment. We negotiate dedicated warehouse space on a project-by-project basis.
- Shipping and distribution: Completed products can ship back to the manufacturer or directly to end customers. We can also ship stored inventory in scheduled batches.
Assembly and Shipping for Coated Products
Using separate vendors can add part transfers between facilities. Keeping assembly, packaging, storage, and distribution with us can reduce those transfers.
Large Part Powder Coating FAQs
Q: What information about large parts should I include for my powder coat RFQ?
A: Send us the part material, quantity, overall dimensions, weight, coating specification, and requested delivery date. Include the part drawing with the request.
Q: Are there areas that should remain uncoated?
A: Threads, mating faces, bearing seats, and electrical contacts may require masking. Mark each no-coat area and coating boundary on the part drawing.
Q: Is it okay to leave seals, bearings, or other components attached to the assembly?
A: Powder coating requires the metal part to reach the powder manufacturer’s specified cure temperature. Seals, lubricated bearings, electronics, and other heat-sensitive components may require removal before the assembly enters the oven.
Q: Is Advanced Finishing capable of matching an existing color?
A: We can match a color from existing equipment or a published color standard. Project documents can list the applicable RAL or Federal Standard code.
Q: Is the thickness of powder coating on large parts adjustable based on the end application or part design?
A: Yes. Electrostatic polyester commonly produces a film from 2 to 4 mils. Fluid-bed epoxy typically ranges from 5 to 25 mils, and specialized applications can require thicker films.
