Shell moulding is a process for producing simple or complex near net shape castings, maintaining tight tolerances and a high degree of dimensional stability. Shell moulding is a method for making high quality castings. These qualities of precision can be obtained in a wider range of alloys and with greater flexibility in design than die-casting and at a lower cost than investment casting. The process was developed and patented by Croning in Germany during World War II and is sometimes referred to as the Croning shell process.
Advantages
· Better surface finish
· Better dimensional tolerances.
· Reduced Machining.
· Less foundry space required.
· Semi skilled operators can handle the process.
· The process can be mechanized.
Disadvantages
· The raw materials are relatively expensive.
· The process generates noxious fumes which must be removed.
· The size and weight range of castings is limited.
Applications
- Crankshaft fabrication
- Steel casting parts, fittings
- Moulded tubing fabrication
- Hydraulic control housing fabrication
- Automotive castings (cylinder head and ribbed cylinder fabrication)
ABOUT KEVA
Keva Casting is a professional casting company that focuses on Construction, Machinery, Automobile, Hardware, Pipeline and many other industries.
We provide top quality products with the best service based on our complete production chain including our own mold design, advanced production techniques, and full management of the supply chain. Keva Casting has two factories located in Zhucheng, China's Shandong province.
We use "shell molding", which is a new technique that has been developed in recent years.This new technique has simplified production procedures and reduced air pollution compared with traditional sand casting and investment casting. Shell making and core making are faster to ensure production in enormous quantities. The dimensions and surface finishing are satisfactory for all kinds of industrial requirements. Besides supplying our own formwork & scaffolding systems, our casting products also supply OEM services in various industries.
