02 Exhibits good wear resistance with high hardness (3000HV) due to Si as dopant. 03 Exhibits stable tool life for cutting materials such as plastic injection molds, etc. where tool seizure often occurs. (2x the tool life compared to conventional products.) Realizes longer tool life in cutting prehardened steel such How to choose mould steel?Topworks plastic mold company Mar 27, 2021 · The requirements vary depending on the structure of the mould, the service life of the mould, the plastic used for moulding, and the performance, appearance, and dimensional accuracy of the moulded product. A mould steel should possess qualities or attributes relevant to the intended application.
Mar 11, 2019 · After thermal treatment, the 2311 pre-hardened plastic mold steel possesses a great processing and polishing performance, and is more suitable for EDM. Generally, it can be used for production of large plastic molds and plastic mold bases. Influence of nickel content on machinability of a hot-work Feb 01, 2011 · In the present study, the influence of nickel content on the machinability of a prehardened hot-work tool steel was investigated. The machinability with varying nickel content from 1 to 5 wt.% was characterized in end milling and drilling by evaluating tool life, cutting forces, and tool/chip interface temperature.. Nickel content showed to have a positive effect on the
Oct 01, 2000 · Plastic parts are usually molded in their final shape with very few secondary operations required, if any. Except for some small, precision die cast parts, very few metal parts that will be part of assemblies can be used as-cast or as-struck. Most will need some type of secondary machining operations.
