Case Study: Lighting Hardware Powder Coating Line
Summary
A 50 m modular quick colour-change powder coating line for a lighting manufacturer in Egypt producing street, garden and landscape lights across 500+ SKUs in batches of 200–2,000 pieces. Four automatic stations with two manual touch-up stations and eight independent powder hoppers give a 10–15 minute colour change, poles up to 6 m and bases to 800 × 800 mm run on an overhead chain at 0.6–2 m/min, and annual capacity is 800,000 pieces. Colour-change efficiency improved fourfold and small-batch lead time fell 50%, as reported after commissioning in 2023.
Project Background
The client is a known lighting manufacturer in Egypt, producing street lights, garden lights, and landscape lights. Small order batches and many varieties — the traditional flow line lacked flexibility.
The Challenge
Lighting industry: 500+ SKUs, small order batches (200-2,000 pieces typical), frequent color changes needed. Lighting structures are complex (poles, heads, decorative parts) — coating uniformity is challenging.
MUSI's Solution
MUSI proposed a quick color-change powder coating solution: modular line + fast color-change booth (10-min change) + auto + manual touch-up combination spray stations. Total length only 50 m, but flexibility is exceptional.
Equipment Configuration
| Line type | Overhead chain + modular powder coating |
|---|---|
| Color change time | 10-15 minutes |
| Spray stations | Auto 4 stations + manual touch-up 2 stations |
| Powder hoppers | 8 independent hoppers |
| Chain speed | 0.6-2 m/min (VFD) |
| Max workpiece | Pole 6 m, base 800×800 mm |
| Annual capacity | 800,000 pcs |
| Min batch size | 200 pcs |
Equipment used on this line
- Automatic spray coating lines — overhead chain, floor belt and robotic flexible lines
- Powder coating systems — electrostatic booths, vertical lines, quick colour change and powder recovery
Implementation
60-day delivery. The client's existing line had been running for 12 years; the new line was installed in the same workshop, requiring careful scheduling around ongoing production.
Results
Color change efficiency improved 4x, small-batch order delivery time reduced 50%. The client won several premium lighting projects in Middle East landmark developments.
Client Feedback
"Fast color change is the hardest part of lighting manufacturing. MUSI's solution lets us produce lighting like clothing — orders no longer constrained by batch size."
— Project Manager, Client Side
Selection logic: why this configuration
A quick colour-change booth with eight dedicated hoppers was chosen over a standard booth because the client changes colour several times a shift; the booth is cleaned in 10–15 minutes instead of an hour. Combining four automatic stations with two manual touch-up stations, rather than a fully automatic booth, covers the decorative heads and brackets that guns on reciprocators miss. The line was kept to 50 m so it fitted the existing workshop beside a line that had run for 12 years.

Typical programme
The durations below are typical for equipment of this class and are given for planning; they are not the recorded schedule of this project. A complete line usually runs 90–180 days from contract to acceptance, a single unit 30–60 days.
| Stage | Typical duration | What happens |
|---|---|---|
| Site survey and workpiece review | 5–10 days | Remote review of drawings and photos, or an engineer visit |
| Layout and detail design | 15–30 days | Layout drawing, utilities list and specification sign-off |
| Manufacturing | 45–90 days | Booths, ovens, conveyor, pretreatment and controls built and pre-assembled at the works |
| Shipping | 20–45 days | Sea freight; equipment shipped in sections for on-site assembly |
| Installation | 15–40 days | MUSI supervision with the client's installation crew or MUSI crew |
| Commissioning, training and acceptance | 7–15 days | Trial runs on the client's parts, operator training, acceptance record |

Applicability and limits
The 10–15 minute colour change applies to a plastic-wall booth with cyclone recovery and one hopper per colour. Plants running metallic or bonded powders, or more colours than hoppers, will see longer changes, and a 6 m pole capacity depends on hanging tooling and oven length being sized together.
Results shown in this case study reflect the stated operating conditions and should not be interpreted as guaranteed performance under different feed, production, environmental, or site conditions.
After-sales and spare parts
Warranty on a MUSI coating line runs from acceptance: 12 months on the complete line excluding consumables, 36 months on critical components such as motors, drives and the PLC, and 60 months on structural parts such as steel structure, ducting and oven bodies. Failures within warranty, excluding misuse, are repaired free of charge.
Support starts remotely: the service line is staffed around the clock, a preliminary diagnosis with recommendations is given within 2 hours, and where a site visit is needed an engineer reaches any major city within 72 hours. A spare-parts inventory is held at the Changzhou headquarters with same-day shipping, and customers can keep a dedicated parts stock at MUSI for emergencies. Details are on the after-sales service page.
FAQ
How fast can a powder booth change colour? Ten to fifteen minutes on this line with a quick-clean booth, cyclone recovery and a dedicated hopper per colour, compared with about an hour on the previous line.
What is the smallest batch that makes sense? The client runs batches from 200 pieces; with a 10–15 minute change the cleaning time is small against even a short batch.
How are 6 m light poles handled? On the overhead chain with long-part hanging tooling; the booth openings and oven length were set for 6 m poles and 800 × 800 mm bases.
Why keep manual touch-up stations? Decorative lamp heads and brackets have faces that reciprocating guns cannot reach; two manual stations after the automatic guns cover them without slowing the chain.
How long was delivery? Sixty days, with installation scheduled around production on the client's existing line in the same workshop.

QQuestions buyers ask before ordering
quotation · price · lead time · installation · warranty
What information do you need to prepare a quotation?
Send part drawings or photos, the largest part size and weight, the material, the required output per shift, the paint or powder type and number of colours, and the available floor space, ceiling height and power or gas supply. MUSI engineers reply within 24 hours; a recommended configuration and quotation follow once your part data is complete.
How much does this equipment cost?
Budget depends on part size, throughput and the level of automation. Indicative ex-works ranges are published in our complete coating line cost guide; a configured quotation is prepared from your part data. Published indicative ex-works ranges: a complete powder coating line is roughly USD 75,000–230,000 semi-automatic, USD 200,000–600,000 for a standard automatic line and USD 600,000–2,000,000 for a high-throughput automated plant.
What is the lead time?
Standard configurations ship in 30–60 days from contract signing and down payment; custom configurations take longer. The delivery date is fixed in the contract.
Do you install and train operators overseas?
Yes. MUSI engineers carry out on-site installation and commissioning and give 3–5 days of operator and maintenance training. MUSI has delivered 800+ coating lines to customers in 36 countries.
What warranty and after-sales support are included?
12 months full-machine warranty, 36 months on critical components and up to 60 months on structural parts. International customers get 24-hour phone response and 72-hour on-site arrival; spare parts ship from the Changzhou headquarters.
Can the environmental equipment be supplied with the line?
Yes. VOC treatment (RTO, RCO, activated carbon, zeolite rotor), dust collection and paint wastewater treatment are supplied with the coating line under one contract; MUSI has equipped 50+ coating facilities whose projects all passed local environmental compliance reviews.
