Cleaning • After the metal has solidified and cool in the mold. • These molds go to a shake out station where the sand and casting are dumped from the flask. • The casting are shaken free from the molding and some dry sand cores are knocked out. • This process of shake out is called the cleaning of castings.
The casting is broken out of the mould (or ejected) and cleaned. This is finished with the help of a process known as fettling that trims the excess metal out of the casting and caters to the precise dimensions to form the finished product. Based on the casting specs, fettling can be simple and quick, or intricately detailed work.

Approximately 20% of the cost to produce a 10kg ductile casting comes from shakeout, fettling, and cleaning. By combining shakeout, sand screening, casting cleaning, and casting cooling, ferrous foundries can easily reduce these costs by 50% and save $80.00/ton, claims the company.

Extraction and separation of fine metal oxides. After blasting, the cast parts are released from the riser and feeder. The very fine metal oxides emitted by angle grinding, sawing or cutting must be thoroughly extracted to protect personnel and product. For larger castings, flame cutters are used. This requires a large air supply, and the
Cleaning or Fettling of Castings. The series of operations performed in cleaning shop may be grouped as follow: decoring, removing of gates and risers, flow-offs, stripping off adhered sand from the castings, trimming burrs, ribs, and scale after heat treatment, straightening and painting of the castings if necessary, and inspecting for acceptance after cleaning and cutting.
The fettling process. Fettling turns a raw casting into a functional component. After removing the molds, the process starts with degating and surface cleaning to remove excess material and achieve the desired basic shape. The part can then be heat treated depending on requirements of the final application.
Mary McMahon "Fettling" is a term commonly used to describe the maintenance of railroad tracks. Fettling is a word that is used in several different senses. Most of the uses of the word relate to cleaning, polishing, and maintaining systems so that they will be functional or will remain functional. The word itself is derived from a root word referring
Fettling Shop . Fettling Shop. The Fettling shop is designed for finishing of the castings. Final treatment of castings covers removal of the gating system and the risers and repair of the casting defects. Final cleaning of the castings in Shot Blasting chamber and heat treatment for stress relief are accomplished there.
1. _____ is the name given to the removal of cores from the casting. a) Fettling b) Pouring c) Molding d) Machining Answer: a Clarification: Fettling is the name of the process to cover all those operations which help to give the casting a good appearance after the casting has been shaken on a vibrator and then taken out of the sand mould.

Fettling and Cleaning. Cleaning comprises the essential process of removal of sand, scale, and excess metal from the casting. The procedure entails separating the casting from the mould and transporting it to the cleaning department, where, burned-on sand and scales are eradicated, improving the surface appearance of the casting.

Keller''s Clean Casting brings air filtration to every step of the casting / metal forming process. With increasing focus on improving air quality standards and the explosive properties of light alloy metals, it has never been more important to ensure the solution and process match.
Processes Fettling and Final Finishing. Fettling: Our final finishing department deals with the removal of runners and risers which are surplus to the casting process. The department is well equipped with both hand and air-operated tooling and also deals with any straightening or final dressing which may be necessary prior to Heat Treatment or CNC Machining for example.
