Shaanxi Rongbao Machinery Electronics Co., LTD specializes in manufacturing the Cast Instrument Box, a precision-engineered aluminum alloy protective housing designed for industrial measurement equipment. This product utilizes ADC12 aluminum alloy through high-pressure die casting, achieving an optimal weight of 0.8kg per unit. With production capacity reaching up to 5,000 pieces per batch and certified under ISO 9001:2015, ISO 14001, and ISO 45001 standards, Rongbao delivers enterprise-grade protective solutions backed by 14 utility model patents and over 20 years of manufacturing excellence. Your equipment demands reliable protection that combines lightweight durability with precision dimensions.

Your industrial equipment demand rugged protection from the environment and lightweight portability. Our protective housings provide just that balance.
The manufacturing procedures combine high pressure die casting with the precision of CNC machining. The dual method assures dimensional precision with tight tolerances. Shot blasting surface treatment offers an evenly textured finish that improves both the look and durability of a part.
The ADC12 aluminium alloy material has good corrosion resistance. It can survive in tough industrial conditions with minimum weight. Your installation crews will enjoy the reduced burden of carrying equipment for setup.

Rongbao's integrated production process simplifies your supply chain management. One trustworthy partner from early mould development through to delivery of final components.
We house several casting methods under one roof. Your instrument boxes are made in high pressure die casting in constant quality. Gravity casting and sand casting are still available for particular purposes.
After casting, the machining centers carry out the processes. The mounting holes, sealing grooves and connection ports are also precisely defined by CNC equipment. Assembly teams set up the components for immediate integration.
The manufacturing cycle is completed by facilities for surface treatment. Shot blasting cleans and creates the perfect surface texture. And we can add other treatments such as powder coating or anodising depending upon your environmental needs.
A custom solution is required for each individual application. Rongbao takes custom orders with a minimum order of around 100 pieces to make special projects worthwhile.
Send us your technical drawings, 3D models or specification sheets. Our engineering team assesses your needs and suggests the most suitable manufacturing methods. Every feature is carefully thought out, from wall thickness to reinforcement ribs to mounting configurations.
Prototyping services are used for validating designs before full-scale production. The mould manufacture is usually 15-25 days and then the batch production is 7-20 days. We continue to offer regular orders from 20-30 working days to ensure your project deadlines are met.

International certification is evidence of our consistently high quality. ISO 9001:2015 – Quality management system in production cycles ISO 14001 ensures that all activities are environmentally responsible.
ISO 45001 certification ensures worker safety and keeps productivity high. These management methods offer structures for continual improvement and defect avoidance.
The composition of the aluminium alloy is confirmed by material testing before casting. Dimensional checks are performed at several stages throughout production. Pressure testing is used for applications needing sealed enclosures to maintain structural integrity.
The Cast Instrument Box serves diverse measurement and control equipment. Gas meter manufacturers utilize these housings to protect sensitive metering components from weather exposure and physical impacts.
Utility companies benefit from corrosion-resistant properties during outdoor installations. Chemical processing facilities appreciate the housing's ability to withstand aggressive environmental conditions.
Water treatment systems, HVAC controls, and industrial automation sensors all require protective enclosures. Your specific application receives the same attention to detail regardless of industry sector.
About 70% of our production is sold into overseas markets including the United States, Europe and Japan. Our considerable export experience means we understand your documentation requirements, packing standards, and shipping methods.
Your instrument housings are protected in wooden box packaging for foreign delivery. Container loading optimisation ensures safe arrival at your site while minimising freight expenses.
All shipments are accompanied by compliance documents. Traceability across your supply chain Material certificates, dimensions reports and quality inspection records.

Q: What materials can you use besides ADC12 aluminum?
A: We work with various aluminum alloys including A380, ADC10, and custom specifications. Material selection depends on your mechanical property requirements, corrosion resistance needs, and budget considerations.
Q: Can you modify existing designs?
A: Absolutely. Provide your current design files and describe desired modifications. Our engineering team assesses feasibility and recommends manufacturing approaches that minimize tooling costs while achieving your performance goals.
Q: How do you ensure consistent quality across large batches?
A: Statistical process control monitors critical parameters during production. Automated measurement systems check dimensions continuously. Random sampling triggers additional inspections when variations approach tolerance limits.
Q: What surface finishes are available?
A: Beyond shot blasting, we offer powder coating, anodizing, chromate conversion, and polishing. Each finish provides different aesthetic and protective properties suited to specific environmental conditions.
Q: Do you provide technical support after delivery?
A: Yes. Our technical team remains available to address installation questions, performance optimization, or design refinement for future orders. Long-term partnerships benefit from accumulated knowledge about your specific applications.
