Tensile testing refers to a test method that measures the process characteristics of a material specimen under axial tensile load until it deforms or breaks. The data obtained from the tensile test can be used to determine the material's elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, yield strength and other tensile performance indicators. Creep data can be obtained from tensile tests conducted at high temperatures. The steps for metal tensile testing can be found in ASTM E-8 standard...

As a common technology for metal material forming, casting achieves efficient manufacturing of complex components by injecting molten metal into the mold cavity and solidifying it. This technology integrates the principles of material solidification, fluid dynamics and thermodynamics, forming a complete scientific chain from microstructure control to macro process optimization. Based on the ASTM A802 casting quality standard and the ISO 8062 tolerance system, this paper systematically analyzes the technical characteristics and application boundaries of mainstream casting processes, and reveals the technical logic of its industrial evolution.
Casting tolerance: the art of balancing precision and cost In the manufacturing industry, casting is the core process of metal forming, and its tolerance control directly affects the dimensional accuracy, assembly performance and manufacturing cost of parts. Casting tolerance is not a simple stacking of numbers, but a systematic engineering that requires comprehensive consideration of process characteristics, material properties, size scale and economy. This article will systematically analyze the key points of casting tolerance from basic concepts to practical applications. I suddenly thought of this topic today because last year a British customer wrote the accuracy as ±0.1% when inquiring for a quote, and specifically told us that it was not ±0.01%. This detail made us feel that the customer's needs are the key to our correct work. Next, let's take a look at some standards for casting tolerances.
In the "magical world" of metal material processing and heat treatment, normalizing, annealing, quenching and tempering are like four magicians with different personalities but super powers. They can give metal materials completely different "super powers" by waving their magic wands. However, for those who have just entered this field or have only a superficial understanding of heat treatment processes, these four magicians are often difficult to distinguish. Don't worry, today we will unveil their mystery and make them clear!
On May 18, 2025, during the "21st Annual Meeting of China Foundry Association", China Foundry Association released the "2024 China Foundry Industry Data". Wang Dongsheng, Executive Vice President and Secretary General of China Foundry Association, released the data and interpreted it in detail. The release of this data is like a mirror, clearly reflecting the complex changes in China's foundry industry in terms of output, imports and exports, an
At Sinostar MACH,we specialize in producing Austempered Ductile Iron castings tailored to meet the demanding requirements of industries such as automotive, construction, agriculture, rail, mining, and heavy machinery. Our expertise in advanced heat treatment ensures that our ADI castings deliver exceptional performance and durability under harsh operating conditions.
The Beijing International Marine Engineering Technology and Equipment Exhibition (CM for short) was held at the Beijing China International Exhibition Center (New Hall) from March 26 to 28, 2025.
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.
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.
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.

ISO 17804:2005 "Classification of Cast Austempered Ductile Iron" is an ISO standard rather than a standard from a single country. This standard specifies the grades and corresponding requirements for austempered ductile iron, and classifies austempered ductile iron based on the mechanical properties measured from machined test pieces. These test pieces may also be made from separate cast samples, cast sample(s), or cut from castings. And it also sets up two levels according to the division of hardness function. ISO 17804:2005 has been replaced by ISO 17804:2020, which is the current version. But ISO 17804:2005 still has a certain historical significance and reference value in the foundry industry.
