What Is Normalizing?
Normalizing is a process that makes the grain size normal. This process is usually carried out after forging, extrusion, drawing or heavy bending operations. […]
What Is Annealing?
Annealing is the process of heating the steel to a particular temperature in the austenite region and cooling down the steel very slowly. There are many derivatives of the annealing process, but generally the process is a slow cool process. […]
Introduction to Principles of Heat Treatment
If we consider the primary metal of steel, which is iron, there are a number of features that we can observe immediately about the metal: […]
What Is Heat Treatment as Applied to Steel?
Heat treatment – as applied to steel – can be defined as the application of heat to change a characteristic or condition of the steel. […]
How to Polish Mold Steels
Polishing, the final step in the mold building process, is highly dependent on the experience and technique of the polisher. However, if the material is not a “mold quality steel,” it may be virtually impossible to bring it up to the required finish. […]
How to make a mold with high added value?
Moldmakers in today’s competitive environment are called upon many times to be more than skilled professionals at building quality tooling for a customer. Because they are asked at times to be a plastics expert (“What shrink should we use?”), process technician (“What mold temperatures do we need to run and how fast?”) and automation inventor [...]
A good mold is based on a well making process
Molders are constantly looking for ways to produce consistent, high-quality parts while maximizing output and uptime. One of the best ways to achieve this is through the use of an effectively engineered mold base. […]
Graphite is very important to EDM Performance
EDMing thin ribs is a difficult application. High-speed machining of the elec-trodes has made it possible to fabricate these electrodes from grades that are not capable of maintaining the detail in the cavity. […]
Making Graphite in High-Speed Machining
High-speed machining centers have made it possible to machine intricate detail into almost any grade of graphite, a task that would have been impossible using manual or CNC machining equipment. […]
How to grade within Classifications in graphite
The physical properties of each grade of graphite determine the ranking within classifications. The properties that influence performance are particle size, flexural strength and shore hardness. […]
