Cast Iron vs Cast Steel | Metal Casting Blog

Cast iron is often cheaper than cast steel because of the lower material costs, energy, and labor required to produce a final product. Raw steel is costlier to purchase, and it requires more time and attention to cast. When designing cast products, however, it is worth considering long …

Defects and electroplating - SlideShare

Hot Tearing • Begins along inside corners of casting if thermal contraction is hindered • Occurs when an outside corner of the die is over-heated • Solidification of the corner is retarded, freezing & contraction of metal on either side applies stress, resulting in cracks to semi-solid metal 45. Hot Tearing (Cont'd.)

Classification of Manufacturing Costs and Expenses

After some costs have been classified as manufacturing, they are normally further classified as direct and indirect. Materials used in the manufacturing process are either used directly or indirectly. Direct material is material that becomes part of the finished product and, therefore, significantly adds to the weight or size of the product.

Pig iron - Wikipedia

Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.

For this reason, semi-permanent mold castings are also available. These molds have expendable cores, making them more manageable and less costly to remove. The final casting process is sand casting. With sand casting, castings are made by pressing a pattern into a fine mixture of sand. This forms a mold for the molten metal to be poured into.
