ADI (Austempered Ductile Iron) Casting News & Technical Articles – SMEMACH

Metal castings can range in size from a few grams to several tones, shape complexity from simple to intricate and order size one-off to mass production.

Does the name of Austempered Ductile Iron (ADI) sound a bit difficult to pronounce? It doesn't matter, you can think of it as the "Iron Man" in the material world - not only has high strength and high toughness, but also wear resistance and shock absorption, it is simply "proficient in all kinds of martial arts". After being treated by the isothermal quenching process, the microstructure of ADI is like a specially trained super soldier, ready to show its prowess in various industrial fields at any time. Now, let's take a look at the wonderful performance of this "Iron Man" in various industries!

Europe also has a deep foundation in the formulation of ADI standards. Before the introduction of the EN 1564-1997 standard, each European member state had its own ADI standard, which to some extent hindered the circulation and application of ADI materials in Europe. In order to break this situation, the European Committee for Standardization (CEN) took a key step in 1997 to unify the standards of 19 European member states and formulate the EN 1564-1997 ADI standard.

Coated sand casting in the foundry field has a long history, casting production is also quite large; Shandong Province is currently China's casting film sand manufacturers are more concentrated areas, Sinostar MACH professional film sand casting parts has been more than 15 years of history, the basic technology has been very mature, the current use of film sand casting production of precision steel castings face a number of problems that need to be solved, such as sand sticking (scars), cold barriers, porosity, etc., how to solve these problems remain to be our further exploration and Solve these problems.

Casting is an indispensable and important part of the development of equipment manufacturing industry, in machine tools, automobiles, instruments, shipbuilding and aerospace and other fields have a wide range of applications.

Casting and forging are common metal processing methods used to manufacture a wide variety of metal parts. However, the defects may occur during casting and forging processes, such as porosity, slag entrapment and cracks, which may......

Casting Defects: The "Hidden Reef" of Quality Risk in Industrial Manufacturing In the field of industrial manufacturing, castings are core basic components, and their importance is self-evident. From the key transmission components of large-scale mechanical equipment to the tiny functional components in precision instruments, castings are present in all kinds of mechanical products and engineering structures. The quality of castings directly determines the performance, safety, stability and reliability of the entire system, and is a key link that cannot be ignored in industrial production.

In the casting industry, those of us who've been around for a while know that controlling the composition of metal materials is the cornerstone of product quality and safety. Positive Material Identification (PMI) testing is a crucial means for us to maintain quality control, ensuring that cast components meet design standards. Among the myriad testing technologies available, Optical Emission Spectroscopy (OES) has emerged as an indispensable core detection method for casting enterprises due to its high precision and efficiency. Today, let's delve into the four major types of PMI testing technologies for casting components, with a special focus on the advantages, applicable scenarios, and detection contents of OES technology.

​In the application field of metal materials, whether it is a foundry or a forging plant, the performance of metal materials is directly related to the quality, safety and service life of the products. Among them, the impact test of metal materials plays an indispensable role as an important means to evaluate the performance of materials under sudden impact loads.

In various fields where metal materials are widely used in industrial manufacturing, hardness, as one of the important mechanical performance indicators of metal materials, is like a precise ruler, measuring the quality and applicability of materials. Especially in scenarios with strict requirements for heat treatment, hardness testing has become the core means of evaluating the mechanical properties and performance of metal materials, providing a key basis for companies focusing on casting and forging products to control product quality.
