aluminum electrical enclosures
Aluminum enclosures are ideal for protecting sensitive electronic components in both indoor and outdoor environments. They offer inherent EMI/RFI shielding and are available in a range of sizes and styles, including waterproof models that meet NEMA 4X, 6, 6P, 12, 13 and IP67/IP68 standards. Commonly used in industries like transportation, manufacturing, and electrical, these enclosures are valued for their:
✓ Excellent corrosion resistance for long service life
✓ High impact resistance for industrial durability
✓ Effective heat dissipation for thermal management
✓ Lightweight and machinable design for easy handling and customization

Diecast Aluminum Enclosures
Diecast aluminum enclosures are specially designed protective housings used to safeguard sensitive electrical and electronic components. These enclosures are made through a diecasting process, where molten aluminum is injected into a mold to form a strong, lightweight, and durable casing. They are ideal for applications that require high durability, excellent corrosion resistance, and protection against physical impacts, dust, and moisture.
Effective Heat Dissipation: The material's excellent thermal conductivity allows for efficient heat dissipation, which is crucial for preventing overheating of sensitive electrical equipment.
EMI/RFI Shielding: Diecast aluminum enclosures are ideal for applications where electromagnetic interference (EMI) or radio-frequency interference (RFI) needs to be minimized, offering inherent shielding to protect electronic components.
Waterproof Options: Many diecast aluminum enclosures come with waterproof ratings like IP67 or IP68, making them suitable for environments exposed to rain, splashes, or temporary submersion.

We offer a wide range of aluminum enclosures, including:
Extruded Aluminum Enclosures – Ideal for lightweight, customizable housings with excellent heat dissipation.

Perguntas frequentes
What is an aluminum electrical enclosure?
An aluminum electrical enclosure is a protective box made from aluminum, designed to house electrical or electronic components. It shields equipment from dust, moisture, and environmental damage, especially in industrial and outdoor settings.
What are the benefits of using aluminum enclosures?
✅ Lightweight – Easier to install and transport than steel.
✅ Corrosion-resistant – Ideal for outdoor or marine environments.
✅ Good heat dissipation – Aluminum conducts heat efficiently.
✅ EMI shielding – Provides natural protection against electromagnetic interference.
✅ Durable and strong – Withstands tough conditions while being easy to modify.
Are aluminum electrical enclosures waterproof?
Yes, many aluminum enclosures are rated IP65, IP66, or IP67, meaning they are dust-tight and resistant to water jets or temporary submersion. Always check the IP rating for your specific use case.
Where are aluminum enclosures commonly used?
Industrial control systems
Outdoor electrical panels
Renewable energy installations (solar, wind)
Marine environments
Telecommunications
Automation equipment
É possível personalizar as caixas de alumínio?
Sim! A maioria dos fabricantes oferece:
Recortes personalizados para conectores e ecrãs
Revestimento em pó ou anodização
Gravura ou serigrafia
Opções de montagem interna (trilhos DIN, suportes, etc.)
As caixas de alumínio são adequadas para utilização no exterior?
Sem dúvida. Com uma vedação adequada e um tratamento de superfície (por exemplo, anodização ou pintura a pó), as caixas de alumínio apresentam um bom desempenho em ambientes exteriores adversos.
As caixas de alumínio requerem ligação à terra?
Sim, o alumínio é condutor. Uma ligação à terra adequada garante a segurança elétrica e contribui para a blindagem eletromagnética.
Que classificação IP devo procurar?
IP54 – Poeira e salpicos leves
IP65 – À prova de poeira e resistente à água
IP67 – À prova de poeira e submersível até 1 metro durante 30 minutos
Escolha em função da exposição à chuva, ao pó ou à imersão.
