Shell Moulding Process

2023-09-15
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)
