Cutting Tools
Cutting processes involve using hard materials to cut soft materials, and pressure-resistant materials to cut brittle materials. Metal materials, depending on their grade, are classified as hard or soft, and as tough or brittle. Metal cutting tools are made of very hard ...Read more -
Analysis and Prevention of Common Casting Defects（2）
Cold Shut Causes: The molten metal has a low pouring temperature and poor fluidity; the gating system design is unreasonable — the number of ingates is too small, the cross-sectional area is insufficient, and the sprue height is too low, resulting in inadequate metal hea...Read more -
Analysis and Prevention of Common Casting Defects（1）
There are many types of casting defects. The following mainly introduces the causes and preventive measures of common ones. Blowholes and Pinholes Blowholes can be classified into three types according to their formation mechanisms: entrapped blowholes, precipitat...Read more -
Casting Quality Technical Inspection
Tasks of Technical Inspection The main task of technical inspection is to promptly detect defects in the inspected objects and to prevent the production of castings that do not meet the specified requirements. According to the stage of production in which the inspection ...Read more -
Shrinkage Cavities and Porosity in Castings
During the solidification process of castings, due to the liquid shrinkage and solidification shrinkage of alloys, cavities are likely to appear in the last solidified regions of the casting. Large and concentrated cavities are referred to as shrinkage cavities (commonly...Read more -
Applications of Ductile Cast Iron
Ductile cast iron has been widely used across various industrial sectors. Due to its many excellent properties and economic advantages, it has replaced — and continues to replace — other materials. Since its discovery, ductile cast iron has primarily competed with forged...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 -
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 -
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 -
304 Stainless Steel
304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. Among all stainless steel materials, 304 stainless steel is almost the most common grade. The density of 304 stainless steel is 7.93 g/cm³. The professional name of 304 st...Read more
