Characteristics of steel based on its melt process and inclusions.

Different polishing techniques include stroke burnish, gloss finish, and mirror finish.

A polishing technique that results in a matte finish.

Polishing technique that gives a shiny but not reflective surface.

A highly reflective polishing technique achieving a perfect shiny surface.

Enhances surface finish, aids demoulding, improves appearance, and prevents corrosion.

Degree of irregularity on a surface measured in micrometers.

Polishing can account for 10-30% of total mould costs, impacting overall pricing.

Materials applied to moulds to enhance life and reduce wear.

Wear caused by hard particles scraping against surfaces.

Wear due to chemical reactions, such as acidic outgassing.

Wear that occurs from sliding contact between parts during operation.

A manufacturing process for creating parts by injecting material into a mould.

A coating process that uses physical processes to deposit materials as vapor.

A coating process using chemical reactions to deposit solid films.

The ease with which a part is removed from its mould.

The ease of shaping steel using processes like turning, drilling, or milling, influenced by carbon content and alloying elements.

Compounds like manganese sulfide that reduce friction during machining and improve hardenability of steel.

Steel with low carbon and up to 1.5% manganese that enhances chip shape during machining.

Low concentrations of phosphorus improve chip breaking and surface quality during machining.

Lead added to low-alloy steels lowers melting point and forms a lubricating film, enhancing chip breaking and reducing tool wear.

A machining method where materials are removed using electrical discharge, producing high precision results.

A type of eroding where a wire electrode cuts through a workpiece with high precision without contact.

A process where sparks generated by electric discharge remove material, used for tight tolerances.
