FAQs

Machine selection depends on the substrate, product dimensions, coating type, required finish, production capacity, application method, and available factory space. SENLIAN evaluates these factors before recommending a suitable coating machine or a complete production-line configuration.

Yes. The working width, conveying height, machine dimensions, feeding direction, and selected process parameters can be customized according to the product size, workshop layout, and production requirements. Final specifications are confirmed after technical evaluation.

Yes. SENLIAN can configure a complete automatic coating line according to the required production process. Depending on the application, the line may integrate surface preparation, dust removal, roller or spray coating, leveling, drying or curing, conveying, and other supporting equipment.

In many projects, yes. Before proposing an integration solution, we review the existing line layout, conveyor height, production speed, equipment interfaces, available space, and upstream and downstream processes. This helps determine how the new equipment can be incorporated without unnecessarily changing the existing production flow.

Please provide the substrate, maximum and minimum product dimensions, coating type, required surface finish, target production capacity, current process, available workshop space, and desired level of automation. Product photos, coating specifications, layout drawings, and production videos can also help us evaluate the project more accurately. You can also send your project requirements to SENLIAN for technical review.

The choice mainly depends on the product shape, coating material, finish requirements, and production target. A roller coating machine is generally more suitable for flat substrates that require consistent film application and efficient continuous production. Spray coating is better suited to shaped components, edges, profiles, and surfaces that cannot be coated effectively with rollers.

The process is determined by the substrate properties, surface condition, coating viscosity, required finish, application method, curing requirements, and production capacity. Different substrates may require different preparation, coating, and drying processes, which is why SENLIAN develops dedicated coating solutions rather than applying one standard process to every material.

Consistent coating thickness depends on stable coating supply, controlled application parameters, uniform conveyor speed, and proper machine adjustment. In roller coating, roller pressure, roller gap, rotational speed, and coating viscosity are critical. In spray coating, coating flow, atomization pressure, gun settings, spraying distance, and conveyor speed must remain properly controlled.

A coating line can often be designed with adjustable parameters to process a defined range of product sizes and production conditions. However, process compatibility depends on the substrates, coatings, drying methods, product shapes, and required finishes. For compatible flat-panel applications, a customized UV roller coating line can combine multiple coating, sanding, leveling, and curing stages within one continuous process.

Coating compatibility depends on the substrate, coating viscosity, application method, curing method, and required finish. Depending on the machine and application, SENLIAN equipment can work with coatings such as UV, PU, PE, NC, AC, water-based coatings, fluorocarbon coatings, adhesives, and other application-specific materials. The coating should be evaluated together with the substrate and process before the final machine configuration is confirmed.

Yes. When process verification is required, sample testing can be arranged before the final equipment configuration is confirmed. Customers can provide representative substrates, coating information, and target finish requirements so that application parameters, drying or curing conditions, and finished-surface results can be evaluated.

Please provide representative substrate samples, coating samples or technical data sheets, target finish requirements, and information about the current production process. Product dimensions, expected production speed, and known coating problems are also useful when determining suitable test conditions.

Production capacity is evaluated based on product dimensions, working width, conveyor speed, number of coating passes, drying or curing time, process sequence, and daily operating hours. Each process must be balanced so that one machine does not become a bottleneck within the complete coating line.

Yes. For customized projects, a production-line layout can be prepared after the coating process, main equipment configuration, and workshop conditions have been confirmed. The layout is used to verify equipment arrangement, line direction, operating space, maintenance access, and connections between machines before manufacturing begins.

The drying or curing method depends mainly on the coating formulation, substrate, film thickness, required curing time, production speed, and temperature sensitivity of the workpiece. Depending on the process, options may include UV curing, LED UV curing, infrared heating, hot-air drying, or high-temperature drying. The appropriate paint drying oven should therefore be selected together with the coating process rather than as an independent machine.

The process depends on the wood species, board type, coating system, and required finish. A typical wood coating process may include sanding, dust removal, coloring, sealing, primer application, sanding, topcoating, leveling, and drying or curing. Solid wood, MDF, plywood, particleboard, and veneered panels may require different process combinations.

A glass coating process should be designed around glass type, surface cleanliness, coating formulation, required finish, application method, drying conditions, and production speed. Cleaning and drying before coating are particularly important because surface contamination can affect coating adhesion and finish quality.

A fiber cement board coating line is configured according to board dimensions, surface condition, coating system, required decorative or functional performance, production speed, and drying method. Depending on the application, the process may include surface preparation, roller or spray coating, leveling, drying, curing, and conveying.

Yes. Installation and commissioning support is arranged according to the project scope, equipment configuration, and destination. Support may include installation guidance, machine adjustment, process commissioning, trial production, and verification of the complete line before normal operation.

Yes. Operator training can be provided as part of the commissioning process. Training typically covers machine operation, parameter adjustment, routine inspection, cleaning, maintenance procedures, and basic troubleshooting for the supplied equipment.

Technical documentation is prepared according to the supplied machine or production line. Depending on the project, the documentation may include operating instructions, electrical diagrams, equipment drawings, maintenance guidelines, component information, and other documents required for installation and operation.

After-sales support covers equipment operation, technical troubleshooting, process adjustment, maintenance guidance, and spare-parts requirements. When technical assistance is needed, customers can provide the machine information together with photos, videos, alarm messages, or operating parameters so that our engineers can identify the issue more efficiently.

When requesting replacement or spare parts, please provide the machine model, component location, available part number, and clear photos of the component. For electrical or mechanical parts, photos of the nameplate or specification label can help us identify the correct replacement more efficiently.
