Shaanxi Rongbao Machinery Electronics Co., LTD. specializes in manufacturing high-precision Casting Lamp Holder Assembly components using advanced gravity casting technology. Our lamp holder assemblies feature A356 aluminum alloy construction with an impressive 25kg weight capacity, engineered specifically for Roman column architectural lighting applications. With 14 utility model patents and recognition as a National High-Tech Enterprise since 2003, we deliver integrated manufacturing solutions that combine gravity casting, CNC machining, and shot blasting surface treatment. Our production capacity reaches 5,000-10,000 pieces per product line, supported by ISO 9001:2015, ISO 14001, and ISO 45001 certifications. Exporting 70% of our products to the United States, Europe, and Japan, we provide reliable OEM/ODM customization with a standard MOQ of approximately 100 pieces.

Our product is the building block of the architectural lighting systems. The system provides electrical connections and mechanical stability for large decorative fixtures.
Units are precision gravity cast to provide dimensional accuracy. The A356 aluminium alloy composition has outstanding corrosion resistance and heat dissipation qualities. This will make your lighting systems safer and more robust in outdoor conditions.
The 25 kg weight enables large lamp structures. This heavy load bearing capacity will assist your Roman column lighting designs. The assembly is structurally adequate for demanding architectural applications.

Gravity Casting Method
We use gravity casting for your lamp holder assemblies giving you higher material density. This treatment removes the internal porosity which affects the structural strength.
A356 aluminium is free-flowed molten into precision moulds. The controlled cooling cycle creates a homogeneous grain structure throughout the casting. You get consistent mechanical qualities across batches of your completed parts.
CNC Milling Precision
After casting, every assembly is treated with CNC machining. This additional technique ensures tight dimensional tolerances to electrical fitting connections.
Thread specs conform to worldwide lighting standards. Your installation teams appreciate the easy assembly with compatible electrical systems. Mounting surfaces are manufactured to flatness specifications to ensure proper fixture attachment.
Shot Blasting Surface Finishing
Shot blasting prepares the aluminium surface for long term environmental exposure. It removes casting scale and produces consistent surface texture.
This procedure improves paint adherence for your unique finish requirements. The surface obtained shows very good resistance to air corrosion. Your outdoor lighting installations will continue to look good throughout their service life.
Key AdvantagesMulti-Process Integration
Our facility combines casting, machining, and surface treatment under one roof. You eliminate coordination delays between multiple suppliers.
The integrated workflow reduces your total procurement time by 30-40%. Quality control occurs at every manufacturing stage. This comprehensive approach ensures your Casting Lamp Holder Assembly meets exact specifications.
Customization Flexibility
We manufacture according to your drawings, 3D models, or technical specifications. Our engineering team supports design optimization for castability and cost efficiency.
Custom modifications accommodate unique architectural requirements. Whether you need specific mounting configurations or modified weight distributions, we adapt our manufacturing process. Your project receives components engineered for exact application needs.
Quality Assurance
Our ISO 9001:2015 certified quality management system governs every production step. Dimensional inspections verify conformance to your tolerance requirements.
Material testing confirms alloy composition and mechanical properties. We maintain full traceability from raw material receipt through final shipment. Your purchase orders receive documentation supporting quality verification.
Global Supply Experience
With 70% export volume to international markets, we understand global compliance requirements. Our team navigates international shipping logistics and customs documentation.
We've successfully supplied components to equipment manufacturers across three continents. Your cross-border procurement benefits from our established export procedures. Communication occurs in professional English with technical accuracy.
Roman column lighting systems represent the primary application for these assemblies. The substantial weight capacity supports large decorative fixtures characteristic of classical architecture.
Historical building restoration projects utilize our components for authentic period lighting reproduction. Modern architectural designs incorporate Roman column elements where our assemblies provide structural lighting foundations.
Commercial properties, including hotels and civic buildings, deploy these assemblies in entrance lighting. The corrosion-resistant A356 alloy withstands coastal and industrial atmospheric conditions. Your maintenance intervals extend significantly compared to alternative materials.

Q: What is the minimum order quantity for custom specifications?
A: Our standard MOQ is approximately 100 pieces for customized product orders. This quantity balances tooling costs with your project requirements while maintaining competitive unit pricing.
Q: How long does production take from order confirmation?
A: Regular orders require 20-30 working days. If new mold manufacturing is necessary, add 15-25 days to the timeline. Batch production of repeat orders completes within 7-20 days.
Q: Can you modify the weight specification for different applications?
A: Yes, we customize weight and dimensions according to your technical requirements. Our engineering team evaluates your specifications and recommends optimal casting parameters during the quotation phase.
Q: What certifications support quality claims?
A: We maintain ISO 9001:2015 for quality management, ISO 14001 for environmental systems, and ISO 45001 for occupational safety. Material certifications and dimensional inspection reports accompany each shipment.
Q: Do you provide samples before bulk production?
A: We offer sample production following mold completion. Sample evaluation allows you to verify fit, finish, and performance before authorizing full production runs.
