Effect of Carbon Content on the Process Properties of Iron–Carbon Alloys
Machinability The machinability of metallic materials is a highly complex issue, generally evaluated from aspects such as allowable cutting speed, cutting force, and surface roughness. Factors including the material’s chemical composition, hardness, toughness, thermal co...Read more -
Hot Working of Metals
Hot Working and Cold Working of Metals Plastic deformation processing is a method of forming and modifying metals by applying pressure. However, when plastic deformation is performed at room temperature, work hardening occurs, which increases the resistance to def...Read more -
Investment Casting
Investment casting is a process in which several layers of refractory coatings are applied to the surface of a wax pattern. After hardening and drying, the wax pattern is melted and removed by heating, forming a mold shell with a cavity corresponding to the shape of the ...Read more -
Application of Casting Process Equipment – Core Boxes and Flasks
Core Boxes In foundry production, except for a few simple castings that do not require cores to form the internal cavities or holes, most castings use cores to form their inner structures. A core box is the necessary mold for manufacturing cores. Its dimensional accuracy...Read more -
Application of Casting Process Equipment — Patterns and Pattern Plates
Patterns A pattern is one of the essential tools in the molding process. Its function is to form the mold cavity, and therefore, the pattern directly determines the shape and dimensional accuracy of the casting. To ensure casting quality and improve molding productivity,...Read more -
Repair of Casting Defects
stings with defects are not necessarily scrap. With necessary repairs to remove the defects, as long as the technical requirements of the casting can be met, most repaired castings can still be used as finished products. The purpose of repairing casting defects is to avo...Read more -
Design of Cores
The core is an important part of the mold. Its function is to form the inner cavity and holes of the casting, to shape undercuts, and to produce parts of the mold that have special requirements. A core should meet the following requirements: the shape, dimensions, and po...Read more -
Filling Ability of Liquid Metal
Concept of Filling Ability of Liquid Metal (1) Filling Ability of Liquid Metal The ability of liquid metal to completely fill the mold cavity and form a casting with complete shape and clear contours is referred to as the filling ability of liquid metal. In most c...Read more -
Lost Foam Casting
Lost foam casting, also known as full mold casting, is a casting process in which a foam pattern coated with a refractory material is placed into a sand mold. Dry sand is then compacted around the pattern. During pouring, the high-temperature molten metal causes the foam...Read more -
Common Methods for Testing and Sampling Mechanical Properties of Castings
The mechanical properties of castings are important indicators of the quality of most castings and are often used as the basis for acceptance. However, it is very difficult and usually impossible to apply the same load to the castings as the working conditions to measure...Read more -
Gray Cast Iron Performance – Service Properties
Machines operating under different conditions require gray cast iron components to have service properties that cannot simply be characterized by conventional mechanical properties. Designers and manufacturers must give this due attention. Wear Resistance Gray cas...Read more -
Gray Cast Iron Performance – Mechanical Properties
The mechanical property data of gray cast iron is generally obtained from separately cast ⌀30mm test bars. Since the microstructure and mechanical properties of gray cast iron are significantly affected by the cooling rate during the solidification and eutectoid transfor...Read more
