DongAn Group Solutions for the Machinery Manufacturing Industry

【Background】

In the machinery manufacturing industry, control enclosures serve as the core electrical control unit for all types of mechanical processing equipment and production lines. Their durability, vibration resistance and protection performance directly determine the operational stability, processing accuracy and service life of mechanical equipment.

Supported by robust structural design, premium material selection and customized protection solutions, Dong'an Group control cabinets are widely applied in the machinery manufacturing sector, including heavy machinery, construction machinery and general machinery. Featuring outstanding impact resistance, wear resistance and corrosion resistance, they meet the stringent operating requirements of machinery manufacturing scenarios and have earned the trust of numerous machinery manufacturers.

【Case Introduction】

Impact Resistance and Load-bearing Optimization of Control Enclosures for Heavy Machinery

A heavy machinery manufacturer producing large excavators, cranes and other heavy equipment was confronted with intense vibration and strong impact during equipment operation. Conventional control enclosures featured fragile structures prone to deformation, with internal components easily damaged, resulting in frequent equipment failures, delayed construction progress and shortened equipment service life.

1、High-load and Impact-resistant Structural Design

The enclosure is made of high-quality 2.0mm cold-rolled steel plate, adopting a double-layer reinforced frame and rib structure with high overall rigidity. It withstands severe vibration and impact generated by heavy machinery operation and prevents enclosure deformation. Internal electrical components are mounted with shockproof fixed brackets, and wiring terminals adopt anti-loosening design, effectively avoiding component damage and wire falling off caused by vibration.

2、High Protection Grade Configuration

Adopting a fully sealed structure with IP65 protection rating and fitted with oil-resistant and wear-resistant sealing strips, the cabinet effectively blocks the intrusion of dust, oil stains and muddy water in construction environments and prevents internal electrical components from moisture and corrosion. A drip-proof eave is designed on the enclosure top to avoid rainwater infiltration, perfectly adapting to outdoor construction scenarios.

3、High-temperature Resistant Heat Dissipation Design

Heavy machinery operates with high load and large heat generation. The control enclosure is equipped with high-efficiency cooling fans and large-area heat sinks, and adopts an independent air duct design to rapidly dissipate internal heat. Compared with ordinary control enclosures, the internal temperature can be reduced by 15℃~20℃, preventing failures caused by overheating of components and ensuring continuous and stable equipment operation.

Application Effect

After adopting DongAn Group control enclosures, the failure rate of the heavy machinery has been reduced, with zero cabinet deformation. The continuous operation time of equipment is extended to more than 2,000 hours, and operation and maintenance costs are greatly lowered. The solution effectively guarantees construction progress and has gained wide recognition from construction enterprises.
