Robotic Spray Painting Systems: Cost Drivers and Specs

What a Robotic Spray Painting System Costs

Ask ABB or FANUC what a spray painting cell costs and you get a quote back instead of a published figure. At The Bot Scout, we read both makers' own product documents for this guide.

FANUC's P-250iB product page ends at a "Get a Quote" button. ABB's IRB 5500-22 FlexPainter datasheet lists payload, reach, controller size and color-change performance, with no price among them.

The cell around the arm moves the quote more than the arm itself does. The booth, the atomizer stack, the color-change hardware, the air handling and the explosion-rated enclosure are what move it.

ABB's datasheet shows how much process equipment rides on a paint arm. The IRB 5500-22 integrates color change valves for up to 32 colors with circulation, plus two pumps driven by integrated servo motors and 64 pilot valves. It also integrates atomizer control with dual shape air, closed loop regulation of bell speed, and high voltage control.

Ask for each of those items as a separate line in the quote. You can then compare two bids item by item instead of comparing two totals.

The controller takes its own floor space. ABB's IRC5P is a separate cabinet measuring 1450 x 725 x 710 mm and weighing 180 kg, and it serves a 600 kg robot on a 500 x 680 mm footprint. Add the 600 kg robot and the 180 kg cabinet and you are placing 780 kg of equipment, so plan the floor, wall or overhead structure before the quote arrives.

The hazardous-area rating is the line item a general-purpose arm does not carry. FANUC's P-250iB catalog prints a US rating of Class I, II, III Div. I Group C, D, E, F, G T4 (Gas, Dust), and ABB lists an Ex certified (explosion-protection certified) FlexPaint Pendant. Write the rating your booth needs into the request so every bid prices the same certification.

Send each maker a written spec instead of a general inquiry. The table below lists what to put in it, line by line.

Return any bid that skips one of these rows, and ask for the missing line before you compare totals.

How a Paint Robot Differs from a Standard Industrial Arm

A paint robot is certified for hazardous areas and built to carry paint process hardware on the arm. FANUC documents the P-250iB hazardous-area rating, and ABB documents the process equipment integrated in the IRB 5500-22 arm.

FANUC prints the P-250iB rating as Class I, II, III Div. I Group C, D, E, F, G T4 (Gas, Dust) for the US. If your plant sits outside the US, get the applicable rating from FANUC in writing, using the P-250iB catalog as the reference document.

ABB rates the IRB 5500-22 at IP67 with an IP54 wrist. Its FlexPaint Pendant is Ex certified.

FANUC says its patented hollow wrist and through-arm hose routing support a clean application environment.

FANUC names the P-50iB alongside the P-250iB in its hollow-wrist section and shows the P-40iA in a video caption. Request specifications for those two models through the FANUC paint robot series page.

ABB mounts paint regulation equipment, like the pumps, as close as 15 cm from the wrist. The color change valves, pumps and pilot valves are integrated in the process arm itself.

Compare a paint robot only against another paint robot. A general-purpose arm, like the ones in our manufacturing robots guide, does not carry the explosion-protection rating, so its price gives you no fair baseline.

ABB IRB 5500-22 vs FANUC P-250iB Specifications

The ABB IRB 5500-22 FlexPainter and the FANUC P-250iB are the two paint robots whose own documents supply every figure in the table below. Use the table to shortlist on mounting, reach and certification, then take the shortlist to quotes.

The two makers do not publish every figure on a common basis. ABB prints static repeatability of 0.15 mm and FANUC prints repeatability of ±0.20 mm, and the two are not stated on a common basis, so do not read a winner from those numbers.

Reach is printed on two different bases too. ABB's drawing prints R 2975, while FANUC lists a maximum reach of 2800 mm and a swing arm variant that extends the work envelope to 3,575 mm.

Payload has the same problem. ABB lists 13 kg of handling capacity at the wrist, and FANUC lists 15 kg maximum payload.

Pick the ABB IRB 5500-22 if you want color change valves for up to 32 colors integrated in the arm and a published color-change measurement. Pick the FANUC P-250iB if you want the 3,575 mm swing arm envelope or rail mounting inside the booth.

Color-Change Waste on a High-Mix Line

ABB prints one measured example for the IRB 5500-22. With 26 colors, a 6 cc pump and the IPS "push-out" function in use, ABB reports paint loss under 15 cc and a color change time of 8 seconds. ABB calls the measurements "real life" and says they include the atomizer.

ABB ties that small loss to where the hardware sits. It mounts paint regulation equipment, like the pumps, as close as 15 cm from the wrist, and says the placement "reduces paint and solvent waste during color change significantly."

Run the arithmetic on your own schedule. If your line changes color 100 times a shift, ABB's example works out to under 1,500 cc of paint (100 x 15 cc). Change time comes to 800 seconds (100 x 8 s), about 13 minutes.

Measure your current paint loss and time per change, then multiply by the same count. The gap between your number and ABB's is the saving to weigh against the quote.

ABB's figure comes from one configuration. Ask ABB to state paint loss and change time for your color count, pump size and atomizer, using the example in the IRB 5500-22 datasheet as the template.

ABB also says its RB1000 atomizer family "significantly reduces the number of robots needed in a spray booth." Ask every bidder how many robots your booth needs, and compare bids on that count.

Neither the ABB datasheet nor the FANUC material cited here prints a transfer-efficiency percentage. Treat any transfer-efficiency figure in a sales presentation as unverified until the bidder writes it into the contract.

Solvent-Borne, Water-Borne and Powder Coatings

ABB states that solutions for both solvent-borne and water-borne paint are available for the IRB 5500-22. Name your paint chemistry in the quote request so ABB prices the matching solution.

Ask FANUC in writing which paint chemistries the P-250iB is configured for, through the P-250iB product page, and attach the answer to the bid.

FANUC's US rating line for the P-250iB reads Gas, Dust. Ask FANUC, citing the P-250iB catalog, whether that rating covers your powder booth.

If your plant runs liquid paint and powder, request the two quotes separately. Separate quotes keep the powder hardware from disappearing inside the liquid line's total.

Neither document read for this guide covers a powder configuration, so treat every powder claim in a bid as unsourced until the maker puts it in writing.

When a Robotic Spray Painting System Is the Wrong Choice

A paint robot is the wrong purchase for a line with low color mix, low volume, very large or occasional parts, no booth, or no budget for hazardous-area compliance. Each of those conditions removes part of the case for the quote.

The documented saving sits in color change. ABB's example is under 15 cc and 8 seconds per change, so a line that changes color a few times a week leaves little waste for a robot to recover.

Very large parts can exceed the work envelope. Compare your part against ABB's printed R 2975 and FANUC's 2800 mm reach or 3,575 mm swing arm variant. If the part is longer, ask about FANUC's elevated and in-booth rails.

A paint robot's certification has to match the booth it works in. If you have no booth, scope and quote the booth first, then bring that rating to the robot quote.

We recommend a paint robot for a high-mix line that changes color many times per shift, already runs a booth, and can fund a certified cell. Keep the current method on a low-mix, low-volume line.

Two things would change that recommendation. A published list price from ABB or FANUC would let you run payback math before a quote. A measured manual color change that already wastes less than ABB's example would shrink the saving.

If your plant has other cells to automate first, compare the options in our robotic automation overview and the robotic welding guide.
