To choose a paint line conveyor system, start with the parts you need to coat, the required production rate, and the full process route—including loading, pretreatment, painting, curing, cooling, and unloading. Then use those requirements to determine the conveyor type, operating speed, hanger or fixture design, load capacity, and layout. The right system is not simply the fastest option; it is one that moves each part reliably through the required process conditions while fitting your floor space and operating plan. At Jingzhongjing Group, we recommend defining these details before comparing equipment proposals.

A conveyor affects how parts are presented to the coating process, how consistently they travel through each stage, and how operators access loading and unloading points. If the line speed, part spacing, or carrier design does not match the product mix, bottlenecks or handling difficulties may result. A useful selection process therefore begins with actual production requirements rather than a preferred conveyor type. Gather information from production, coating, maintenance, and plant-layout teams before requesting a design.
List the smallest and largest parts, their dimensions, weight, shape, and coating surfaces. Include how parts will be oriented and whether they need a dedicated jig, hook, rack, or other fixture. If product sizes vary, identify the usual mix as well as the heaviest or most difficult items, since these can influence carrier clearances and loading practices.
Next, establish the expected output and schedule. Separate target output from maximum theoretical capacity, and note planned shifts, changeovers, and periods when the line may be stopped. This information helps the system designer consider practical operating conditions instead of sizing only for an ideal continuous run.
Write down each process stage in sequence, including manual work areas and any required accumulation or inspection points. Note where parts enter and leave the line, where operators need access, and where the conveyor must change direction or elevation. The route should account for the space needed around ovens, spray areas, maintenance access, and safety provisions, subject to the project’s applicable requirements.
For each stage, confirm the conditions the part and carrier must tolerate. These may include heat exposure, moisture, chemical contact, overspray, or cleaning requirements. Do not assume that a carrier suitable for one section is automatically suitable for every section; ask the supplier to review materials, clearances, and operating conditions across the whole route.
Use the target output and carrier spacing to estimate a starting speed. For a simple continuous flow, the relationship is: speed in meters per minute = carrier spacing in meters × required carriers per minute. If one carrier holds multiple parts, convert the required part output into the number of carriers needed, and account separately for loading efficiency, changeovers, and process constraints.
For example, an illustrative layout with carriers spaced 1.5 m apart and a target flow of 4 carriers per minute gives a nominal speed of 6 m/min. This is a calculation example, not a recommended speed for every coating line. Confirm the actual value against the process, product handling, operator tasks, and equipment limits before specifying a drive system.
Some coating stages require a defined time in a zone, so compare the proposed conveyor speed with the usable process length. A basic planning relationship is: dwell time in minutes = process-zone length in meters ÷ conveyor speed in meters per minute. For instance, a 30 m zone at 6 m/min corresponds to 5 minutes of travel time; this example does not establish that five minutes is appropriate for a particular coating or curing process.

Obtain the required time and operating conditions from the coating-material supplier, process engineer, or equipment specification. If line speed changes, the time spent in a fixed-length zone changes as well. Consider this relationship early, because changing oven length or production rate later can affect layout, energy use, and throughput planning.
Overhead conveyors can keep parts above the floor and may suit routes that pass through multiple process zones, but they require appropriate building clearance and support planning. Floor-mounted systems can be considered where overhead structure or part suspension is unsuitable, although they need floor space and must work with the handling and cleaning plan. Power-and-free arrangements may be useful where sections need different movement or accumulation behavior, but their control and layout requirements should be evaluated for the application.
These are general selection considerations, not a substitute for a project-specific design. The right configuration depends on part geometry, loading method, process sequence, desired flow, available building structure, and maintenance access. Ask the supplier to explain why the proposed arrangement fits your actual route rather than relying on a type name alone.
Determine the expected load per hanger or carrier, including the fixture and all parts. Confirm how the supplier treats maximum load, load distribution, curves, inclines, and any accumulation points in the proposed design. Uneven or shifting loads can create handling and operational concerns, so describe the real part orientation and loading pattern.
Review controls and interfaces with the rest of the line. Identify whether the conveyor needs variable speed, zone coordination, interlocks, or integration with existing equipment, and define who is responsible for specifying these interfaces. The required functions should be written into the scope so that design, installation, and commissioning teams share the same expectations.
| Decision area | Information to confirm | Why it matters |
|---|---|---|
| Product and load | Part dimensions, weight, orientation, and product mix | Influences carrier design, clearances, and handling |
| Required output | Target parts per hour, carrier quantity, and shift plan | Provides the basis for speed and capacity estimates |
| Process route | Zone sequence, dwell requirements, and access points | Connects conveyor layout with coating requirements |
| Plant conditions | Available footprint, building clearances, and utilities | Helps assess installation and layout feasibility |
| Project scope | Equipment boundaries, controls, installation, and support | Reduces gaps between supplier and buyer responsibilities |
Prepare a concise technical brief that includes part drawings or representative samples, weights, target output, process stages, available floor plan, and known utility or building constraints. Mark required operating conditions separately from preferences, and flag any information that is still unconfirmed. This helps suppliers identify assumptions and ask focused questions before finalizing a proposal.
Request a layout drawing and a written explanation of the proposed conveyor route, speed basis, carrier concept, load assumptions, and project scope. Compare quotations on the same basis, including included equipment, exclusions, documentation, installation support, and commissioning responsibilities. If a supplier uses different assumptions, ask for a revised comparison rather than treating the quoted price as directly equivalent.
As a paint line conveyor system manufacturer and supplier, Jingzhongjing Group can review your production brief and discuss a configuration for your application. Useful starting information includes part dimensions and weights, expected output, process sequence, available layout, and any existing equipment the conveyor must connect with. Where details are not yet settled, we can identify the questions that need confirmation before a final specification is prepared.
The best paint line conveyor system for your production needs is the one designed around your actual parts, target flow, coating route, and site constraints. Begin by mapping the process, documenting product and load details, and estimating speed and dwell time with clearly stated assumptions. Then verify the conveyor type, carrier design, controls, maintenance access, and project responsibilities with the supplier. Contact Jingzhongjing Group with your production requirements to start a practical equipment discussion and identify the next information needed for a project-specific proposal.
