One such device that solves people’s problems is the ejector pin. Often considered a commodity, they are nonetheless critical to the successful function of a mold. The list of what can go wrong due to problems with them is endless. […]
Managing heat and delivering resin at a consistent temperature is the role of the nozzle. There are several features that one should consider before making a nozzle choice. It is important to maintain consistent heat due to the temperature processing window unique to today’s highly engineered resins. […]
Ion Nitriding: Ion nitriding is a surface treatment method of diffusing nitrogen in the surface of the steel to enable the nitrogen to react with alloying elements that will readily form stable nitrides. […]
Isothermal Transformation Temperature: The isothermal transformation temperature is commonly known as the Triple T Diagram (TTT). […]
Intergranular Cracking: Intergranular cracking is a condition in the steel that that will occur between the grain boundaries of the steel. […]
Induction Hardening: Induction hardening is a method of steel surface heat treatment. In order to be able to induction heat treat (harden) the surface of a steel, […]
Hardness: Hardness is the measurement of the steel’s resistance to indentation by pressing into the surface of the steel a specific object—such as a steel or molybdenum ball or diamond indenter—using very specific loads. […]
Hardenability is the ability of the steel to produce the appropriate hardness in relation to the amount of martensite when quenched for its austenitizing temperature into the appropriate quench medium. The resulting hardness will be according to its cross-sectional area and chemistry (composition). […]
Water Hardening Tool Steels: Low hardenability, water quench necessary to form martensite.Oil Hardening Tool Steels: High wear resistant steels. […]
In order for tool steels to be identified by a toolmaker, it is necessary for the toolmaker to understand the method of identification and classification of tool steels. The purpose of gaining this understanding is that there are so many different tool steel manufacturing companies that will produce a very high grade of tool steel [...]
