Frequently Asked Questions

Ketu is a Chinese manufacturer focusing on complete powder coating lines, curing ovens and related equipment. We design, fabricate and test full systems in our own factory, and we also operate in-house powder coating lines. Every proposal is based on real production experience, not only catalog data.

We mainly serve B2B factories and OEM manufacturers: metal furniture producers, electrical cabinet and enclosure factories, aluminum profile plants, and job-shop coating plants. Most of our contacts are owners, production managers, plant engineers and project teams responsible for capacity, quality and ROI.

Our core strength is complete powder coating lines, including pretreatment, drying, powder booth, curing oven and conveyor. However, if you already have part of a line and need to upgrade ovens, booths or conveyors, we can also provide key equipment and integrate it into your existing system after a technical evaluation.

Yes. Many projects start from upgrading old liquid painting or outdated powder lines. We can evaluate which parts can be reused and which parts must be replaced to meet your new capacity, quality and environmental requirements.

Our equipment has been exported to markets such as Turkey, India, North Africa and Southeast Asia, and we are open to cooperation worldwide. For each market we consider local regulations, power standards, gas availability and environmental requirements during design.

Yes. We are happy to cooperate with local agents, installers and engineering companies. In many cases, a local team supports civil work and installation, while Ketu provides equipment, drawings, technical guidance and process know-how.

The basic data we need includes: product types and photos, maximum dimensions and weight, daily/shift output, current coating process, available workshop size and layout, preferred heating source and target quality level.

Manual lines are suitable for small batches, many colors and frequent changes. Semi-automatic lines are ideal for growing factories that need stable flow but still want flexibility. Automatic lines fit large-scale, repeatable production.

Yes. We design line layouts around existing columns, doors, forklift paths and loading areas. U-shaped, L-shaped and multi-level layouts are all possible.

Our curing and drying ovens can be designed for natural gas, LPG, diesel, electricity or a combination, depending on your local energy cost and availability.

Yes. We supply pretreatment tanks, spray tunnels, pumps, filters and heating systems according to your substrate and corrosion resistance requirements.

For furniture and job-shop customers, we can design powder booths and powder feeding systems for faster color change: smooth interiors, optimized suction and optional quick-change powder centers.

Usually the buyer arranges civil work, foundations, platforms and on-site installation teams. Ketu provides detailed layout drawings, loading lists, assembly drawings and technical guidance.

It depends on line size and local conditions. A simple manual line may take a few weeks, while a large automatic line with pretreatment can take several months.

Yes. During commissioning we train your operators and maintenance staff on start-up, shutdown, safety checks, parameter settings, cleaning routines and troubleshooting.

Daily tasks usually include checking temperature and pressure, cleaning filters, removing powder build-up in the booth and inspecting conveyor lubrication.

Yes. Conveyor speed, oven temperature, curing time and some pretreatment parameters can be adjusted when your product mix or paint specifications change.

We first troubleshoot via video calls, photos and data logs. Many issues can be solved by simple adjustments or replacement of standard parts.

During design we calculate airflow and duct positions, and during testing we check actual temperature distribution with multiple sensors placed in the oven.

For corrosion resistance, the key factors are pretreatment, powder selection and curing control. We work closely with your powder and chemical suppliers so the whole system meets your requirements.

For key sections we do pre-assembly and dry runs in our factory. We check doors, fans, burners, conveyor drives and safety interlocks.

We control incoming materials, welding quality, panel machining, insulation, wiring and final assembly with internal checklists.

Main cost drivers include line length, automation level, type and size of pretreatment, oven dimensions and heating method, conveyor type, number of colors and required capacity.

Lead time depends on project size and current workload. Small manual lines can often be produced faster, while large automatic systems may require several months.

We usually work with FOB, CIF or CFR terms from Chinese ports. Payment terms are commonly T/T with down payment and balance before shipment.

Yes. Based on your local energy prices, line configuration and expected output, we can provide reference calculations for gas/electricity consumption, powder usage and labor requirements.

We normally offer a standard warranty period for main equipment components. Details will be specified in the contract.

Many basic components can be sourced locally using the specifications we provide. For custom parts, we can supply them from China.

Yes. We support customers via email, messaging and video calls for process adjustment, troubleshooting and future upgrades.

You can send your product photos, basic dimensions, expected output and workshop layout to us. Our team will review your data and reply with initial ideas, concept layout and quotation direction.
