core structure and processing characteristics
The spray-painted motor housing is not merely a simple "box". Its value lies in providing structural protection and functional decoration for the precise electrical components. The core advantage stems from the close integration of the following structures and processes:
Strong base
Made by high-quality aluminum alloy die-casting for one-piece molding, the structure is complete and contains reinforcement ribs, ensuring high strength and excellent heat dissipation performance.
Precise Structure
Features precise installation columns, interface openings and sealing grooves, facilitating the fixation of internal components and achieving excellent dustproof and waterproof (IP rating) performance.
Precise Coating
Through pre-treatment such as degreasing and phosphating, the adhesion of the coating is ensured. Automated spraying and high-temperature curing are employed, resulting in a uniform paint surface that is both wear-resistant and corrosion-resistant.
Strict quality control
The adhesion is tested through the grit test, and the corrosion resistance is verified through the salt spray test, ensuring the reliability of the product's appearance and performance.
Performance Advantage Details
It integrates the functions of robust protection, aesthetic decoration, environmental durability and heat dissipation, and is a key component for enhancing the quality and reliability of electrical products.
Outstanding protection
The sturdy metal die-cast base combined with a dense coating layer offers excellent resistance to impact, corrosion, rust, and chemical substances, effectively protecting the internal precision components.
Long-lasting appearance
The surface paint film has a rich and uniform color, is scratch-resistant and does not fade. It can maintain its beauty for a long time, significantly enhancing the overall texture and brand image of the end product.
Excellent environmental adaptability
Through rigorous salt spray, high and low temperature, and grit blasting tests, it can withstand harsh environments such as high humidity and large temperature variations, ensuring the stable operation of the electrical appliances in various scenarios.
Efficient heat dissipation
The metal material itself has good thermal conductivity, which helps to promptly discharge the heat generated by the internal electronic components, thereby extending the lifespan of the equipment.
Flexible customization
Products can be flexibly customized in terms of strength, color, texture (such as matte, glossy, metallic finish), etc., according to customer requirements, achieving product differentiation.
Reliable sealing performance
The precise die-casting structure enables the easy realization of high-standard dustproof and waterproof (IP rating) designs, meeting the sealing requirements of various devices.
Application scenarios
In summary, any electrical equipment that requires robust protection, efficient heat dissipation, electromagnetic shielding, and a sleek and elegant appearance is a typical application scenario for spray-painted electrical casings.
Appliances
Outdoor and indoor units of air conditioners, control panels of washing machines, control modules of refrigerators, exteriors of microwave ovens.
Kitchen Appliances
Panels and exteriors of ovens, dishwashers, range hoods, induction cooktops, rice cookers, and air fryers.

Medical Equipment Sector
The outer shells of various medical monitoring devices, diagnostic instruments, and medical instrument operation panels have extremely high requirements for cleanliness, corrosion resistance, and appearance texture.
Consumer Electronics and Outdoor Equipment
Commercial display screen enclosures, POS machines, outdoor surveillance camera enclosures, LED outdoor lighting fixture housings, etc. - products that need to withstand harsh environments.
FAQ
Q: What materials are mainly used for the casing of your electrical appliances?
A: We mainly use high-quality materials such as ADC12 aluminum alloy for die-casting. This material has excellent fluidity, strength and lightweight characteristics, and is very suitable for manufacturing complex-structured and high-demand electrical appliance casings.
Q: What colors and effects can surface painting provide?
A: We offer a wide range of color options (supporting Pantone color code matching), and can achieve various surface effects such as matte, glossy/high gloss, metallic texture, sanding texture, rubber paint (hand touch paint), etc., to meet the different appearance and touch requirements of your products.
Q: How is the wear resistance and corrosion resistance of the paint surface?
A: We have a strict quality control process. The paint surface has passed the grit test (adhesion test) and the neutral salt spray test (usually requiring more than 48 hours), ensuring strong adhesion, wear resistance, scratch resistance, and excellent corrosion and rust prevention capabilities, which can adapt to various harsh environments.
Q: Can waterproof and dustproof functions be provided?
A: Yes, it is possible. Through the precise die-casting structure design (such as sealing grooves, stop-fit connections) and subsequent sealing processes (such as installing sealing rings), we can make the housing reach IP54, IP65 or even higher protection levels. The specific design can be carried out according to your product requirements.
Q: How long is the production cycle?
A: The production cycle depends on the complexity and quantity of the order. For new projects, time for mold development needs to be reserved. During the mass production stage, usually after sample confirmation, batch delivery can be arranged within 2-4 weeks. We will provide you with a detailed production plan based on your specific requirements.
Q: Do you support small-batch customization and prototyping?
A: Yes, we do. We can provide small-batch trial production and prototyping services for our clients, allowing you to conduct tests and validations. We have a one-stop service capability covering mold design and manufacturing, die-casting production, surface treatment, and assembly, and can efficiently respond to your customized requirements.
Q: How can we ensure the consistency of quality during mass production?
A: We achieve this through the following methods: Automated production line: Utilizes robot spraying and automated equipment to minimize human errors. Full-process quality control: From the warehousing of raw materials to the final shipment, multiple inspection procedures are carried out (such as first-piece inspection, patrol inspection, and final inspection). Standard process: Strictly follow the standardized operation procedures (SOP) and the quality management system (such as ISO 9001).
Q: Besides painting, are there any other surface treatment methods?
A: Yes. Besides spraying, we also offer other common surface treatment processes, such as anodizing, electrophoretic coating, metal polishing, sandblasting, etc. You can consult our sales engineers to get recommended the most suitable solution for you.
