The cost of an automatic powder coating line depends on more than the spray booth and coating guns. A complete project may include pretreatment, material handling, curing, controls, installation, and factory-specific utilities, so the total price changes with your product dimensions, production target, finish requirements, and project scope. To compare supplier quotations accurately, separate equipment costs from installation and operating costs, then confirm exactly what each quotation includes. At Changjiu Coating, we recommend starting with a defined process and production brief rather than requesting a price for an unspecified “standard line.”
You can find more information on our web, so please take a look.
Use the categories below as a checklist, not as a fixed percentage allocation. Suppliers may package equipment differently, and a lower equipment price may exclude items needed to make the line operational. Request a scope-by-scope quotation so you can identify omissions before comparing totals.
| Cost category | What it may include | What to confirm |
|---|---|---|
| Pretreatment | Cleaning, rinsing, drying, and related process equipment | Process stages, water handling, and compatibility with the substrate |
| Conveyor and handling | Overhead or floor conveyor, hangers, drives, and loading points | Part weight, spacing, route, speed, and return arrangement |
| Booth and powder application | Spray booth, guns, reciprocators where required, and powder recovery | Color-change needs, part geometry, and recovery scope |
| Curing oven | Heating system, insulated enclosure, circulation, and controls | Part temperature requirements, oven capacity, and energy source |
| Controls and integration | Electrical cabinets, line controls, safety devices, and system interfaces | Included control functions, local standards, and connections to plant systems |
| Project and delivery costs | Engineering, packing, freight, installation, training, and commissioning | Site responsibilities, travel, taxes, and exclusions |
Pretreatment is selected according to the workpiece material, surface condition, coating requirements, and applicable process specification. The equipment may range from a simpler cleaning arrangement to a multi-stage system with rinsing and drying. These choices affect equipment, water management, heating, and the space required for the line.
Ask suppliers to state the proposed process stages and the assumptions behind them. Confirm whether water treatment, wastewater handling, chemicals, and any required building connections are included or supplied by your facility. A quotation that lists only a pretreatment “unit” may not make the boundary of supply clear.
Conveyor design affects both the initial investment and how parts move through the process. Relevant inputs include maximum part dimensions and weight, hanging orientation, spacing, production rate, line layout, and the amount of accumulation required. Longer routes, heavier loads, complex turns, or multiple loading and unloading points can change the equipment configuration.
Define capacity in measurable terms, such as required parts per hour, instead of relying on a general description like “high output.” The necessary conveyor speed depends on part spacing and process dwell time, including the time required for curing. Ask the supplier to show how the proposed speed and layout meet your target.
The booth and powder application package should match the part shapes, coating coverage, color-change frequency, and production plan. Equipment scope may include manual or automatic guns, gun movers, powder feed components, filters, and recovery equipment. The right arrangement depends on how parts enter the booth and which areas are difficult to coat consistently.
Discuss overspray handling and cleaning procedures before selecting a system. If your production uses frequent color changes, ask how the proposed booth and recovery arrangement supports changeover and what tasks remain manual. Confirm whether spare parts, installation materials, and operator training are included.
Oven sizing is influenced by workpiece dimensions, conveyor throughput, required time at temperature, insulation, heat source, and the temperature distribution needed for the process. The coating powder supplier’s technical information should guide cure requirements; the oven air temperature alone does not establish that a part has received the required cure. Ask how the supplier plans to verify and control the process during commissioning.

For an illustrative planning brief, a buyer might specify a target of 100 parts per hour, a 20 m conveyor route, and a powder cure condition of 180°C. These are example inputs only, not a recommended line design or Changjiu quotation; actual requirements must be checked against part geometry, powder data, and production conditions. Changing any one of these inputs can affect oven length, conveyor arrangement, energy demand, and the overall project scope.
The quoted equipment price may not include building modifications, foundations, ventilation, gas or electrical connections, compressed air, or local exhaust provisions. Installation labor, travel, unloading, lifting equipment, and commissioning may also be separate line items. Confirm who is responsible for each connection and site task before approving a purchase.
Request a utility schedule that identifies expected electrical supply, fuel or heating requirements, compressed air, and any water or drainage needs. Have your plant team review these requirements alongside the proposed layout. Early review can reveal space or infrastructure constraints before equipment is manufactured or shipped.
Purchase price is only one part of the financial evaluation. The line may also require energy, compressed air, powder, filters, pretreatment chemicals, routine maintenance, and replacement components. These costs vary with operating hours, process settings, material use, and maintenance practices, so ask suppliers to state their assumptions rather than relying on unsupported savings estimates.
When comparing alternatives, consider the equipment’s intended service and the availability of technical support and spare parts. Ask which components are consumables, what maintenance tasks are expected, and whether troubleshooting support is available after installation. A supplier’s response should be specific enough for your maintenance and purchasing teams to evaluate.
Send each supplier the same information so that their proposals address comparable requirements. Include product drawings or representative samples, maximum dimensions and weight, material, desired finish, production target, operating shifts, available floor space, and preferred heating energy. Also explain current pretreatment conditions and any plant standards the line must meet.
Ask each supplier to provide a layout, process description, equipment list, utility requirements, project schedule assumptions, and a clear list of exclusions. Request separate prices for optional items where possible. This makes it easier to distinguish a genuine equipment difference from a difference in quotation scope.
An automatic powder coating line budget should account for pretreatment, conveying, application and recovery, curing, controls, integration, delivery, installation, and ongoing operation. The most important cost drivers are the product envelope, throughput, process requirements, plant layout, and the boundary between supplier and buyer responsibilities. There is no reliable single price for every line without these project details.
To move forward, prepare a concise production brief, request itemized quotations, and compare scope, utilities, exclusions, and service arrangements alongside the purchase price. At Changjiu Coating, we can review your product and process requirements to help define a suitable line configuration and clarify the information needed for a project quotation. Share your part dimensions, target output, coating requirements, and facility constraints to begin a practical discussion.
