More Details
The outdoor unit housing serves as the protective enclosure for heat exchangers, compressors, and other critical refrigeration components.
Initial sheet metal cutting is performed via shear or laser to define panel shapes.
Stamping and bending using precision dies form the box structure and include mounting and ventilation features.
Welding or riveting joins individual panels into a rigid and stable assembly, typically using spot welding or TIG/MIG methods.
Surface treatment includes degreasing, phosphating, and coating via spray or electrocoating, followed by curing to produce a durable protective layer against corrosion and environmental exposure.
Key Features & Advantages
1️⃣Structural Reliability
Stamped and welded metal panels provide strong protection against mechanical and environmental stress.
2️⃣Corrosion and Weather Resistance
Surface treatment ensures long-term durability and resistance to UV, moisture, and temperature variations.
3️⃣Precision Assembly
Cutting, bending, and welding processes maintain dimensional accuracy for proper component fit.

FAQs
Q1: Why choose sheet metal over plastic for outdoor units?
Sheet metal provides superior strength, heat resistance, and durability in harsh outdoor environments.
Q2: What surface treatments are used for corrosion protection?
Degreasing, phosphating, painting or electrocoating, and curing provide a long-lasting protective layer.
Q3: Can small-batch prototypes be produced using this process?
Yes. Sheet metal cutting, bending, and welding can be applied to prototype or small-batch units.
Q4: How is assembly accuracy maintained?
Precision dies and controlled welding/riveting processes ensure consistent fit and dimensional stability.
