Standard lead times range from 20-30 working days, with a minimum order quantity of 100 pieces. Each product meets ISO 9001:2015, ISO 14001, and ISO 45001 certification standards.

What Is Aluminum Gravity Cast Flange?

A product is a circular connector component manufactured by pouring molten aluminum alloy into a permanent mold using only gravitational force.

This method produces lightweight flanges with excellent corrosion resistance. The A356 aluminum alloy provides optimal strength-to-weight ratio for cover applications.

Unlike high-pressure casting methods, gravity casting creates parts without external pressure application. This results in reliable dimensional accuracy and good mechanical properties.

The process suits medium-volume production where quality matters more than speed. Each flange undergoes CNC machining to achieve precise specifications.

Technical Specifications

Manufacturing Process Advantages

Rongbao's gravity casting technology is accurate and cost-effective. Under specified temperature settings, molten A356 aluminium flows naturally into metallic moulds.

This does not require high pressure equipment for permanent mould casting. All your parts have a constant density of material throughout their structure.

CNC machining of crucial mounting surfaces guarantees dimensional correctness. Shot blasting treatment gives a homogeneous surface texture and removes any residual casting material.

Ready-to-install flanges are the result of multi-process integration. No dealing with a bunch of vendors for different stages of manufacturing.

Material Properties and Performance

A356 aluminum alloy offers superior characteristics for flange applications. The material density of approximately 2.70 g/cm³ provides 40-60% weight reduction compared to steel alternatives.

Thermal conductivity reaches about 167 W/m·K, preventing localized heat accumulation. Excellent corrosion resistance ensures long service life in various environmental conditions.

Non-magnetic properties make these Aluminum Gravity Cast Flanges suitable for applications with electronic sensors. The alloy maintains structural integrity across temperature fluctuations.

Your equipment benefits from reduced inertia and lower energy consumption. The material's ductility also absorbs vibrations more effectively than cast iron.

Customization Capabilities

Rongbao can be customised according to your drawings, 3D model or specifications. The integrated workflow spans from mould fabrication to delivery of the finished component.

It takes about 15-25 days to get a mould for a new design. After mould approval, batch manufacturing runs are completed in 7-20 days.

You can select specific dimensions, mounting hole patterns or surface treatment requirements. Technical consultation is provided by the engineering team to optimise designs for gravity casting.

ODM services help you when you design new items without finalised drawings. The prototype creation process confirms the design principles before mass production.

Quality Assurance System

ISO 9001:2015 accreditation ensures standardised quality control throughout the manufacturing process. Dimensional checks ensure that your criteria are met at various points during production.

Material tests revealed the composition of the A356 alloy, which fulfils international requirements. Surface quality inspections identify any casting defects before machining operations.

The company has passed ABB's difficult SSBM assessment, demonstrating its capabilities to meet strict international supplier criteria. Environmental management is based on the ISO 14001 standard.

Workplace safety meets ISO 45001 standards. Every batch has quality documentation for traceability.

Application Scenarios

These flanges are used in the making of various equipments. Typical applications include mechanical covers, housings and structural connectors.

The lightweight design is appropriate for applications where reducing weight enhances overall system performance. Their resistance to corrosion makes them suitable for outdoor or humid locations.

You'll find these parts in industrial machinery, automation equipment and specialised manufacturing systems. It is non-magnetic which is why it is used in precision measuring equipment.

Custom specs for individual application requirements across many industries. Gravity casting can be adaptable to many design challenges.

FAQ

Q: What is the minimum order quantity for custom flanges?

A: The standard MOQ is approximately 100 pieces. This quantity balances tooling costs with production efficiency for customized projects.

Q: How long does production take from order confirmation?

A: Regular orders require 20-30 working days total. This includes mold preparation if needed (15-25 days) and batch production (7-20 days).

Q: Can you manufacture flanges from materials other than A356?

A: Yes, Rongbao works with various aluminum alloys based on your application requirements. The technical team recommends suitable materials during the consultation phase.

Q: What tolerances can gravity casting achieve?

A: Standard gravity casting tolerances combined with CNC machining achieve ±0.1mm for critical dimensions. Tighter tolerances are possible through additional machining operations.

Q: Do you provide sample parts before full production?

A: Sample production is available to validate design and quality before committing to batch orders. Sample lead times are typically shorter than full production runs.

Q: What surface treatments are available besides shot blasting?

A: Additional options include anodizing, powder coating, and polishing. Surface treatment selection depends on your application environment and aesthetic requirements.

Q: How do you handle quality issues if they occur?

A: Quality documentation enables traceability for any issues. The company works with you to identify root causes and implement corrective actions promptly.
