Industry Overview
Heavy-duty robotic coating solutions for shipping containers (20ft/40ft ISO), refrigerated display cabinets, reefer trailers and large industrial enclosures. C5 marine corrosivity rating, 15-20 year outdoor service life, food-grade compatible topcoats available for cold-chain applications.
Typical Workpieces
MUSI has served the Shipping Containers & Refrigerated Cabinets industry with workpieces including:
- ISO shipping containers (10ft / 20ft / 40ft / 45ft / HC)
- Reefer containers and refrigerated trailers
- Energy storage containers (ESS housings)
- Refrigerated display cabinets (retail / commercial)
- Cold storage room panels and doors
- Insulated transport boxes and pallets
- Marine and offshore enclosures
- Modular building units and site offices
- Tank container frames and end-walls
- Container chassis and structural frames
Industry Coating Challenges
Each industry faces unique coating challenges. MUSI's solutions are designed to address these pain points directly:
Marine Corrosion Protection
Containers and reefer equipment work in marine and coastal service. Coating systems are specified to C5 marine corrosivity with a 15-20 year outdoor service life, and a full repaint in service is often contractually excluded.
Three Coats and Waiting Time
A three-coat system needs curing between coats. Without forced curing, between-coat waiting limits how many boxes a line can finish per day.
Strict Durability Tests
Container coatings must pass salt spray, UV, thermal cycle and other tests — placing high demands on both coatings and process.
Large, Heavy Workpieces
A loaded 40 ft box sets the size of everything on the line: rails, transfer cars and lifting stations must carry it, and operators need access platforms at roof height.
MUSI's Targeted Solutions
To address these challenges, MUSI provides industry-specific coating solutions:
1. Blast Cleaning Before Primer
Boxes and panels are blast-cleaned in a blast room or on a roller conveyor blast line with media recovery before the primer coat.
2. Three-Coat Booths with Roof-Height Access
A primer booth with stripe-coat access platforms at roof height, followed by intermediate and topcoat booths or a combined spray-and-bake cell. Food-grade compatible topcoats are available for cold-chain equipment.
3. Forced Curing at 60-80 °C
A forced-cure zone at 60-80 °C shortens between-coat waiting, so the line finishes one to four boxes per day.
4. Strict Process Control
Full-line MES integration — real-time monitoring of temperature, humidity, pressure, flow at every station with full traceability of every part's process parameters.
5. Handling and Exhaust Sized for the Box
Rails and transfer cars are sized to a loaded 40 ft box, and solvent exhaust treatment is sized to the three-coat load.
6. Written Performance Specification
Line speed, cure profile, film build and emission level are stated in the contract and demonstrated at the factory trial run before shipment.
