Solidification Under Extreme Conditions — Solidification in Microgravity
Under normal conditions, when the ratio of an object' s acceleration to gravitational acceleration is less than one or even equal to zero, the object is considered to be in a microgravity or weightless state. Under such conditions, the solidification characteristics of m...Read more -
Characteristics of Clay Sand Molds for Iron and Steel Castings
According to the different types of casting alloys, it can be divided into casting sand for cast steel, cast iron, cast copper, aluminum alloy castings, and magnesium alloy castings. Different casting alloys have different pouring temperatures and casting properties, and...Read more -
Classification and Characteristics of Pores in Castings
When the concentration of gas in metal exceeds its solubility, or when the invading gas is not dissolved by the metal, it will exist in the liquid metal as bubbles in molecular state. If the bubbles do not have time to float up and be discharged before the solidification...Read more -
Casting Deformation
Castings with residual internal stresses are in an unstable state—thicker sections are subjected to tensile stresses, while thinner sections experience compressive stresses. In such a state, the casting will spontaneously deform to reduce internal stresses and achieve a ...Read more -
Classification of Coated Sand
Overview Before molding and core making, the molding sand and core sand with a layer of solid resin film on the surface of the sand particles are called coated sand. Coated sand was originally a kind of thermosetting resin sand. The process is to mechanically mix powdere...Read more -
Applications of Shot Blasting
1. Surface cleaning of various castings Shot blasting equipment is first used to remove sand and oxide scale on the surface of steel and iron castings. Almost all steel castings, gray iron castings, malleable cast iron castings, ductile iron castings, etc. need to be sho...Read more -
Shot Peening & sand blasting
Shot peening Shot peening, also known as shot peening, is one of the effective methods to improve the fatigue life of parts. Shot peening is to spray a high-speed stream of projectiles onto the surface of the workpiece, causing the surface of the workpiece to undergo pla...Read more -
Causes of Shrinkage Cavities and Shrinkage in Cast Iron Castings
Formation of shrinkage cavities and shrinkage After the molten iron fills the mold, liquid shrinkage occurs immediately. At this time, shrinkage can be compensated from the pouring system. When the surface temperature of the cast iron part drops to the solidification tem...Read more -
Negative Pressure Casting
Negative pressure casting, also known as vacuum-sealed casting, reduced pressure casting, or V-method casting, is a process that uses vacuum pressure to cover a heated, plasticized plastic film over the pattern and template. Dry sand without any binder is then filled int...Read more -
Gray Cast Iron HT250 Used for Castings
HT250 is a widely used gray cast iron material, which occupies an important position in the industrial field with its excellent mechanical properties and good casting processability. As a classic casting material, HT250 plays an important role in many industries such as ...Read more -
16MnCr5 Alloy Steel Used for Castings
16MnCr5 alloy steel is a commonly used alloy structural steel, belonging to case hardening steel. Due to its excellent strength, wear resistance and hardenability, it is widely used in the manufacture of custom steel gears, shafts and other mechanical parts that require ...Read more -
Detection of Castings Weight Deviation
Related Terms 1. Nominal Weight of Castings This includes the machining allowance and other process allowances, serving as the reference weight to measure the weight of the inspected casting. 2. Weight Tolerance of Castings The allowable range of variation in the wei...Read more
