Lost Foam Casting
Lost foam casting, also known as full-mold casting, involves bonding foam patterns into clusters that resemble the dimensions and shapes of the final castings. These clusters are coated with refractory material and subsequently utilized in the casting process. Cha...Read more -
Riser Design in Casting
Riser design is a crucial aspect of the casting process, ensuring that castings are free from defects such as shrinkage cavities and porosity. Risers, also known as feeders, act as reservoirs of molten metal that feed the casting as it solidifies and contracts. Riser ...Read more -
Design of Chills in Casting
In the casting process, chills are critical components used to control the solidification of molten metal. By promoting directional solidification, chills help minimize defects such as shrinkage cavities and improve the mechanical properties of the final casting. Chills ...Read more -
Sand Core Design in Shell Mold Casting and Sand Casting
Sand core design is a critical aspect of the casting process in foundries, where intricate shapes and internal cavities are formed in metal parts. Understanding the different types of sand cores, the principles of setting them, their fixation and positioning is essential...Read more -
Shrinkage in Castings
Shrinkage in castings is a crucial aspect that significantly impacts the quality and integrity of the final product. Understanding the different types of shrinkage associated with various materials, such as cast steel and cast iron, as well as the factors contributing to...Read more -
Solidification of Metal Castings
Solidification Mechanisms During the casting process, the solidification of castings occurs when the molten metal transitions from a liquid to a solid state. This process can be broadly categorized into three mechanisms: nucleation, dendritic growth, and grain structure ...Read more -
Low Alloy Cast Steel Used for Casting Parts
Low alloy cast steel refers to alloy cast steel with a carbon content of less than 0.45% and a total content of other alloying elements not exceeding 5%. Low alloy cast steel has high strength, good toughness and hardenability. Low alloy cast steel generally contains all...Read more -
Application Fields and Properties of Ductile Cast Iron
Wide range of applications With its excellent physical properties and significant economic advantages, ductile iron is gradually becoming the material of choice in many industrial fields, widely replacing traditional materials such as forged steel, stamped steel, weldmen...Read more -
Quality Inspection of Castings
Visual Inspection Visual inspection is the first and most straightforward method of quality control for castings. It involves a thorough examination of the casting's surface to identify any visible defects such as: Surface Cracks: Small fissures on the surface that coul...Read more -
Introduction to Casting Cleaning
Casting cleaning is an essential process in the manufacturing of metal components, particularly in industries such as automotive, aerospace, and heavy machinery. After the metal has been cast, the resulting product, known as a casting, often requires further processing t...Read more -
Ferritic Stainless Steel Casting
Ferritic stainless steel refers to stainless steel with body-centered cubic ferrite as the matrix structure at high temperature and normal temperature. Ferritic stainless steel has iron and chromium as the main elements, generally does not contain nickel, and some contai...Read more -
Magnetic Particle Inspection of Casting Internal Defects
Magnetic particle inspection is a detection method that uses the properties of ferromagnetic materials (such as steel, iron, cobalt, nickel, etc.) to be magnetized. When the metal casting is strongly magnetized by the magnetic field, if there is a defect perpendicular to...Read more
