High Speed Milling of Hardened Steel Moulds and Press Tools

Abstract. The paper outlines the use of high speed ball nose end milling for the manufacture of hardened steel moulds, dies and press tools. Information on suitable machine tools and cutting tools is given, together with relevant machinability data. The industry is characterised by large numbers of small companies (typically <50 employees) and How to Avoid Tool Steel Corrosion MoldMaking TechnologyJan 24, 2019 · A mold builder should consider corrosion resistance, hardness, machinability, processing, polishability, operational environment and wear resistance during tool steel selection. This pre-hardened free machining stainless steel mold base material resists corrosion associated with high humidity environments and when corrosive resins are used in

P20 Mould Steel - Harrison Special Steels

P20 MOULD STEEL. P20 is an alloy tool steel which delivers and superb polished finish. As a result this is widely specified for machined plastic moulds. Supplied in the hardened condition P20 offers excellent wear resistance. We can supply P20 in flats, and squares in metric or imperial. We can also cut to order.

P20 (1.2311) Pre hardened to approximately 300 B.H (65 t.s.i) P20 requires no further heat treatment therefore avoiding risk of distortion or cracking. Although pre-hardened P20 is still capable of being machined and of giving a good polished finish. Typical applications:Plastic moulds, backers, bolsters, die holders.

    TOOLING:How to Select the Right Tool Steel for Mold

    Aug 25, 2016 · Its a very durable, impact-resistant tool steel that can be hardened up to 56 RC. This steel also is much more stable through the heat-treating process, shrinking or expanding less than H-13 or stainless steel. In most cases, cavities are hardened to 50-52 RC. S-7 can also be used for slides or lifters and hardened to 54-56 RC. Tool Steel Pipe and Round Bar - ACE MetalMay 28, 2018 · These tool steels are low carbon and moderate to high alloy that provide good hot hardness and toughness and fair wear resistance. 6) Special purpose group/plastic mould steel P-type tool is short for plastic mould steels. Common steel grades like P20, 420 etc. L-type tool steel is short for low alloy special purpose tool steel. Tool Steel Suppliers - Tool Steel Grades Delivered P20 tool steel offers outstanding machinability and can be machined into complicated and broad moulds. As a result, it is one of the most commonly accepted grades for plastic moulds and die holders. Furthermore, P20 is capable of leaving a polished finish.
