Advantages
They are widely used in industries such as petrochemicals, machinery manufacturing, power generation, shipbuilding, metallurgy, and water supply systems, and are indispensable connectors in industrial piping systems.
As industrial equipment evolves toward high pressure, large diameters, and highly corrosive environments, flanges are increasingly demanding in terms of material strength, corrosion resistance, and sealing precision.
In this context, high-quality casting processes have become a core component of flange manufacturing. Leierwo provides flanges with a solid structural foundation and guaranteed performance.
Application of Casting in Flange Manufacturing
Casting plays a crucial role in Flange Manufacturing, enabling the formation of complex structures in a single step. This ensures high strength, dimensional stability, and reduces machining costs. Common flange casting types include slip-on flanges, butt-weld flanges, threaded flanges, and blind flanges, which can be produced through sand casting or precision casting.
Key Advantages of Cast Flanges in Flange Manufacturing
Flexible material selection: carbon steel, alloy steel, stainless steel, and other materials can be selected according to pressure level, operating temperature, and media properties.
Dimensionally stable, excellent performance: meets the requirements of high-pressure, high-temperature, and corrosion-resistant operating conditions.
Through precision casting technology, we are able to produce high-precision, high-density flange castings to provide customers with reliable connection solutions.

FAQ
We are a factory with over 20 years of experience in casting and machining. We have rich expertise in this industry. If you come across suppliers claiming to produce castings in a wide range of materials (such as steel, iron, stainless steel, copper, etc.), they are likely trading companies. If you see workshops actively producing parts, you can be assured that we are a genuine manufacturer.
Yes, as long as we receive CAD files or compatible 3D models that can be viewed with software like First Quote or Firstcut browser, we can provide a quotation. Please note that 2D drawings alone are insufficient for manufacturing precision components.
We support 3D CAD models from SolidWorks (.sldprt), ProE (.prt), and other CAD systems, commonly in IGES (.igs), STEP (.stp), ACIS (.sat), or Parasolid (.sat) formats.
We have an internal service system that responds to emails within 4 hours. If your request is urgent, please specify it in your email so we can prioritize your inquiry.
For rapid prototyping:
Silica sol casting: 20โ30 days
Sand casting: 7โ10 days
For mass production with machining included, the typical lead time is 45โ60 days.
More complex parts may require a different delivery schedule.
Yes, we provide samples based on your drawings for you to confirm structure and quality. If the sample does not meet your requirements, we will replace it free of charge until it is qualified.
We accept T/T (bank transfer), Alipay, credit card, etc. Typically, we require a 30% down payment upon order confirmation and the remaining 70% before shipment. For custom parts with complex requirements, additional pricing terms may apply.
We have a comprehensive quality control system that covers every step, from raw material procurement to machining processes and final inspection. For critical components, we strictly follow drawing standards and customer specifications.
All customer data is kept confidential. Only trained engineers are authorized to handle production orders. Third-party inspection or factory audits are welcome, or you may use our in-house quality team for final inspection.
Yes, we guarantee that all materials used are 100% genuine and as specified.
We value long-term cooperation and support our customersโ production needs.
We believe every honest customer is a friend, and we treat our partnerships sincerelyโbuilding friendships and strong teams regardless of where our customers come from.
