Investment Casting for Pump & Valve Components Applications

In the manufacturing of pumps and valves, lost wax casting process plays an important role as it enables itself readily to produce the very complex shapes of pump and valve components. When valve castings and pump castings are made by Lida steel foundry, the additional advantages of very close tolerances and consistent quality are obtained — important factors if the ever increasing demands of modern industry are to be met. Our range of investment casting materials permits selection of the appropriate grade of metal for each type of service, and thus pump & valve castings from our company offer the perfect combination of economical manufacturing and a high standard of service performance. As a consequence, many im­portant valve and pump manufacturers throughout the world cooperate with us for their casting needs.

Lida utilizes precision casting technology to manufacture a wide range of precision casting parts  for pump & valve application for hydraulic and pneumatic equipment including:

• Impellers
• Covers
• Cap Regulators & End Caps
• Valve Bodies
• Valve Discs
• Coil Housings
• Bonnets

Lida is the top lost wax casting supplier in China with rich experience, we can pour various types of casting materials including stainless steel casting, carbon steel casting and high alloy casting to serve wide range of industries including building hardware. Please contact us at: info@lidalostwaxcasting.com to consult our experts to give you a professional answer to your specific questions for your project.

Versatile Types of Casting Options:

Stainless steel, carbon steel, low alloy steel, medium alloy steel, high manganese steel, nickel base alloy, cobalt base alloy, non-ferrous alloy, etc. Please see the following attachment for details.

Capable of Manufacturing Both Small Parts and Large Parts in Size

Our metal parts can be achieved single weight 0.001-300KG,  minimum size at 5mm*3mm*1.5mm, maximum size 1000mm*1000mm*500mm with weight no more than 300kg.

High Dimensional Accuracy : GB/T6414 or ISO 8062, please see the invesment casting tolerances as below:

High Surface Quality:  Surface Roughness before machining: ≤Ra6.3, ≤Ra3.2 after special processing.

Rapid Manufacturing Capacity: By developing lost wax casting 3D printing technology of shell mold, we can rapid prototype samples within 7 days. This technology eliminates the need for pattern tooling production, speed up casting process design and validation, and reduce overall development time when a hard tool is desired for scalable mass production, and thus provides an advantage for market fast promotion and process trial production.

Vacuum Casting Capacity: With vacuum melting furnace, we can produce nickel based and cobalt based alloy casting parts, product weight range: 0.001-25Kg. Part surface made by vacuum casting is more smooth, no air vent and oxidization, which can meet customer's requirements with higher standards Product surface finish is smooth, no air vent and oxidization, which can meet customer's requirements with higher standards, such as aeropace and petrochemical industries.

Lida is good at manufacturing investment casting parts in complex structures: With the aid of the advanced casting simulation software to facilitate product process design, we can use the melt core, ceramic core, salt core, C-1 sand and other special processes to achieve complex structures to meet customer's higher requirements for challenging projects.

Production Process of Lost Wax Casting

FAQ

1. What is the difference between sand casting and lost wax casting?

Lida: With lost wax casting process, it can make as more as 1000 types of parts in varieties of materials with smooth surface, tight tolerance, it can also make very small size parts, and suitable for precise or parts with high requirements on surface smoothness.  

Sand casting can only make limited materials and it has limitation on material, with poor surface and big size tolerance, hard to make small size parts or accessories.

2. What are Lida Green Energy Technology's part size capabilities?

Lida: Maxium size 1000mm*1000mm*500mm with weight no more than 300kg Minimum size 5mm*3mm*1.5mm
