To select automatic powder spray equipment for a production line, start with the parts you coat, the required line speed, the coating changeover pattern, and the space available for the booth and conveyor. Then compare spray guns and controls, powder recovery, part presentation, integration needs, and supplier support as one system—not as isolated equipment. We recommend preparing representative parts and a clear production brief before requesting a quotation, so suppliers can assess the application and identify information that still needs confirmation.

This guide is for production managers, process engineers, and purchasing teams evaluating a new line or upgrading an existing one. It provides a practical framework for defining requirements, comparing system options, planning costs and lead times, and preparing for a technical discussion with Changjiu Coating or another equipment supplier.
Automatic powder spray equipment applies coating powder to prepared workpieces, typically using controlled spray guns within a defined application area. A complete production solution may include an automatic booth, guns and controllers, powder feed equipment, recovery components, and interfaces with the conveyor and curing process. The exact scope varies by project, so distinguish equipment included in the quotation from plant utilities, pretreatment, ovens, and installation work.
Document the range of parts rather than describing only the most common item. Record material, shape, largest and smallest dimensions, hanging orientation, areas that must remain uncoated, and any recesses or Faraday-cage-prone features that may be difficult to coat. Provide drawings or photographs when available, and identify the powder type and finish requirements if they have already been defined by your process team.
Suppliers need to understand how parts move through the line and what production output means for your operation. State the target line speed in metres per minute, or provide required parts per hour and the planned part spacing. As an illustrative planning example only, a buyer might assess a target of 1.0 m/min; this is not a recommended or guaranteed equipment speed.
Also explain the operating pattern, including shifts per day, planned product mix, and expected changeovers. For example, “2 shifts/day” is more useful than simply saying the line will run continuously, but this example does not establish a capacity requirement. The supplier must assess actual output against part dimensions, hanging density, conveyor layout, coating process, and other project conditions.
Automatic systems are commonly designed around a conveyor passing through a spray booth, with guns positioned to coat parts as they travel. The number and arrangement of guns depend on workpiece geometry, required coverage, line configuration, and process validation. Some projects may need a combination of automatic application and manual touch-up access, particularly where parts include complex features.
Powder recovery and booth arrangements should be considered alongside color strategy. A production line with frequent color changes may have different cleaning and recovery priorities from a line dedicated to a single color. Ask how the proposed design handles powder collection, cleaning access, changeover procedures, and the intended treatment of recovered powder; do not assume that every system handles these tasks in the same way.
Ask suppliers to state equipment configuration and relevant operating requirements clearly. Depending on the project, this may include the number and type of guns, controller functions, powder feed arrangement, booth dimensions, conveyor interface, electrical supply, compressed-air requirements, and recovery method. A sample part envelope such as 600 × 400 × 300 mm can help start a discussion, but it is only an illustrative value and must not be treated as your equipment limit.
Confirm how the automatic spray system will interface with upstream preparation and downstream curing. Powder application equipment does not, by itself, define the complete coating process: substrate preparation, powder characteristics, film requirements, and curing conditions also matter. Identify which party is responsible for process trials, oven settings, line controls, guarding, ventilation, and compliance with applicable local requirements.
Prepare a part list that covers routine production as well as the largest, smallest, and most challenging shapes. Include available drawings, material details, coating specifications, and masking or appearance requirements. If requirements are not finalized, mark them as open questions instead of allowing suppliers to make unspoken assumptions.

Share target output, conveyor speed expectations, operating hours, product mix, and color-change frequency. Explain whether the priority is steady high-volume production, flexibility across multiple products, or a balance between the two. These operating priorities can influence booth configuration, gun positioning, recovery choices, and the amount of manual intervention required.
Provide available floor space, ceiling height, conveyor direction, utility information, and the location of existing equipment. Clarify whether the project is a greenfield installation or a retrofit, since existing layout constraints can affect both equipment scope and installation planning. Ask the supplier to identify any assumptions that require a site check before final design.
Use a common comparison sheet covering included equipment, exclusions, capacity assumptions, utility requirements, installation scope, commissioning support, documentation, spare parts, and warranty terms. Compare technical fit before comparing headline price. If one proposal omits recovery equipment or assumes customer-provided installation, its total project cost may not be directly comparable with a broader package.
Automatic powder spray equipment is usually quoted according to configuration and project scope rather than a single universal specification. Price can depend on booth size, number of guns, recovery design, controls, conveyor integration, customization, and service requirements. Ask for a breakdown of the proposed scope, optional items, packing, delivery terms, and any site work that is excluded.
For a production-line system, minimum order quantity may be less useful than confirming the minimum commercial scope for your specific project. Lead time should be discussed against the approved configuration, manufacturing schedule, required documentation, and shipping arrangements. Request a written schedule with the events that start the lead-time clock, and confirm how design revisions or delayed customer inputs could affect it.
During discussions with Changjiu Coating, we recommend sharing the same application brief with each supplier you are evaluating. This helps us understand your part range, line layout, throughput goals, and integration needs before discussing a suitable equipment configuration. Where a requirement remains unclear, ask for it to be recorded as a design question or a condition for final confirmation.
Choosing equipment based only on the number of spray guns or the lowest initial quotation can leave important process needs unresolved. A system that appears suitable for one part may not provide the same coverage or operating flexibility across a broader product range. Review representative parts and changeover requirements before treating a configuration as final.
Another common mistake is overlooking the boundaries between the spray system and the rest of the line. Confirm responsibilities for pretreatment, oven integration, conveyor controls, utilities, installation, and site safety. Also avoid relying on verbal performance expectations; request the assumptions and acceptance criteria in writing, and agree how any trial or validation will be conducted.
The right automatic powder spray equipment is the configuration that fits your parts, output targets, layout, coating process, and support expectations—not simply the system with the most components. Start by documenting representative workpieces, measurable production goals, color-change needs, site conditions, and the desired project scope. Then compare supplier proposals against the same checklist and resolve exclusions before purchase.
As a next step, prepare a part list, drawings or photos, target throughput, operating pattern, and available site information for a technical review. Changjiu Coating can use these inputs to discuss your application and assess a suitable equipment proposal. If key process details are still being developed, identify them early so they can be confirmed before final configuration and scheduling.
