Shaanxi Rongbao Machinery Electronics specializes in manufacturing Cast Motor Housing using advanced sand casting technology and A356 aluminum alloy material. Our motor housing components are engineered to 3.7kg weight specifications with flange applications, delivering production capacity of 500 pieces per batch. Each product undergoes CNC machining and shot blasting surface treatment, meeting ISO 9001:2015, ISO 14001, and ISO 45001 certification standards. With 14 utility model patents and over 20 years of manufacturing expertise since 2003, we export 70% of products to the United States, Europe, and Japan. Our integrated manufacturing capabilities cover mold development through final surface treatment, ensuring dimensional accuracy and structural integrity for equipment manufacturers worldwide.

Motor enclosures require exceptional durability and thermal management properties. Your equipment depends on housings that protect internal components while dissipating heat efficiently.
Sand casting delivers distinct advantages for motor housing production. This process accommodates complex geometries and customized specifications that your applications demand.
A356 aluminum alloy provides optimal strength-to-weight ratios. The material offers excellent corrosion resistance and thermal conductivity, extending motor service life in challenging environments.
Our product components undergo rigorous CNC machining to achieve tight tolerances. Shot blasting creates uniform surface finishes that enhance protective coating adhesion.

Our one-stop production workflow eliminates coordination challenges. You work with a single supplier from initial design through finished component delivery.
Mold Manufacturing (15-25 days): Proprietary core preparation methods support closed twisted blade designs and complex internal structures.
Sand Casting Operations: Molten A356 aluminum flows into precision molds, creating your Cast Motor Housing's foundational shape with consistent material properties.
CNC Precision Machining: Multi-axis equipment achieves your specified dimensional tolerances and mounting interface requirements.
Shot Blasting Finishing: Uniform surface preparation removes casting residue and creates ideal conditions for your protective coatings.
Our multi-process capabilities include high-pressure die casting, low-pressure die casting, and gravity casting. We select the optimal method based on your component's structural demands and production volume.

The motor housing you need depends on your industry and operating conditions. We offer versatile OEM and ODM services based on your technological requirements.
Provide your 3D models, engineering drawings or application parameters. Our technical team reviews the manufacturability and recommends design optimisations to decrease cost without compromising performance.
The normal minimum order size of 100 pieces can handle prototype development or manufacturing runs. Some configurations enable 5,000-10,000 piece capacities . Larger batch sizes benefit from economies of scale .
With export experience to the United States, European and Japanese markets, we know what quality means internationally. We've passed severe SSBM assessments from the world's technological giants like ABB.
Uncompromising quality control is needed to protect your motor's internal components. We have ISO recognised management systems for each step of the production process.
Material verification indicates alloy A356 composition is within mechanical property standards. Dimensional inspections confirm machined features are within your specifications.
Sustainable manufacturing methods are supported by environmental management systems (ISO 14001) and health and safety systems (ISO 45001). These certifications are proof of our dedication to responsible production.
Being named a National High-Tech Enterprise is a reward for our continuous investments in industrial innovation. Ongoing R&D programs lead to enhanced casting techniques and efficiencies.

Q: What makes sand casting suitable for motor housing production?
A: Sand casting excels at producing medium to large housings with complex internal passages. The process offers design flexibility for customized flange configurations and mounting features. You achieve cost-effective tooling compared to die casting, particularly for moderate production volumes.
Q: How does A356 aluminum compare to iron motor housings?
A: A356 provides superior thermal conductivity, dissipating motor heat more effectively than iron alternatives. The reduced weight simplifies installation and reduces shipping costs. Corrosion resistance extends service life in moisture-prone environments without additional coatings.
Q: Can you modify housing designs for specific mounting requirements?
A: Absolutely. Our technical team collaborates on design adjustments to accommodate your mounting systems. We evaluate modifications for casting feasibility and structural integrity before finalizing production specifications.
Q: What delivery performance can international customers expect?
A: Regular orders ship within 20-30 working days after order confirmation. We maintain transparent production schedules and provide progress updates throughout manufacturing. Customer feedback confirms our on-time delivery prevents production delays for equipment manufacturers.
Q: Do you provide technical documentation with shipments?
A: Complete material certifications, dimensional inspection reports, and quality documentation accompany each order. We supply the technical records your quality assurance processes require for incoming component verification.
