Industry Coating Challenges

Each industry faces unique coating challenges. MUSI's solutions are designed to address these pain points directly:

Oversized & Heavy

Heavy equipment can weigh several tons and span over 10 meters — beyond standard line capacity.

Heavy Oil & Rust

Raw steel structures often have cutting oil, anti-rust oil, and oxide layers — strict pretreatment is essential.

Outdoor Durability

Outdoor-use equipment must resist UV, salt spray, acid rain — coating life targets 10+ years.

Small Batches, Many Variants

Typically single-piece or small-batch custom production — difficult to use flow lines, mostly spray booth + drying booth.

MUSI's Targeted Solutions

To address these challenges, MUSI provides industry-specific coating solutions:

1. Large Auto Spray Booths

Standard spray booth 12×6×5 m, with drive-through doors for forklift access. Air supply 60,000-100,000 m³/h with three-stage filtration.

2. Heavy-Duty Pretreatment

High-pressure spray degreasing + shot blast derusting + multi-stage phosphate or silane treatment for excellent coating adhesion.

3. Heavy-Duty Anti-Corrosion Coating

Three-layer system: epoxy primer + epoxy intermediate + polyurethane topcoat — passes 2,000+ hour salt spray, 15+ year outdoor life.

4. Multi-Fuel Curing Ovens

Natural gas, diesel, or electric heating options — adapts to local energy availability.

Recommended Equipment

Typical projects in this industry use the following MUSI products in combination — exact selection depends on workpiece specifics:

Frequently Asked Questions

How large a workpiece can a heavy machinery coating line handle?

Workpieces up to 12 m long and 6 m wide. The standard spray booth is 12 × 6 × 5 m with drive-through doors for forklift access and an air supply of 60,000-100,000 m³/h with three-stage filtration.

What pretreatment does heavy machinery need before painting?

Raw steel structures often carry cutting oil, anti-rust oil and oxide layers. MUSI uses high-pressure spray degreasing, shot blast derusting and multi-stage phosphate or silane treatment to give the coating good adhesion.

Which paint system is used on heavy machinery?

A three-layer heavy-duty anti-corrosion system: epoxy primer, epoxy intermediate coat and polyurethane topcoat, which passes 2,000+ hours of salt spray.

Is heavy machinery coated on a flow line or in a booth?

Heavy machinery is usually built as single pieces or small batches, which is difficult to run on a flow line, so most shops use a spray booth plus a drying booth.

Which fuels can heat the drying booth?

Natural gas, diesel or electric heating, chosen to suit local energy availability.

Questions 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.
