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 -
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 -
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 -
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 -
Rust Prevention of Castings
Investment castings often require mid-term rust prevention. Rust prevention methods generally use rust prevention liquid treatment or oil seals. Castings must be cleaned before rust prevention. Casting cleaning The formula, temperature and use of commonly used cleaning l...Read more -
Welding Repair of Castings
Principle 1. Usually refers to castings that do not meet the acceptance technical conditions or order agreement, have casting defects but can be repaired. 2. The area and number of castings allowed for welding repair are specified. The defect type is usually specified in...Read more -
Shelling and Surface Cleaning of Castings
Shelling and surface cleaning of castings Casting group shell cleaning Cooling of castings After the shell is poured, the cooling time of the casting in the mold is related to the material, shape, size and production conditions of the casting. Generally, for alloy castin...Read more -
Incomplete Annealing & Spheroidizing Annealing of Metal Castings
Incomplete annealing of Metal Castings Definition: Incomplete annealing is a heat treatment process for steel castings, which involves heating the steel to a temperature range between Ac1 and Ac3 (for hypoeutectoid steel) or Ac1 and Accm (for hypereutectoid steel), cooli...Read more -
Mold Assembly in Castings
Mold assembly includes core setting, installation of chillers, core supports, and venting facilities, as well as securing the mold after assembly. The mold assembly for stainless steel investment castings focuses on wax pattern assembly and shell making, omitting the tra...Read more -
Full Annealing for Metal Castings
Definition The heat treatment process of steel refers to the specific heating, insulation and cooling process parameters of steel during heat treatment, which are formulated according to the structural transformation law of steel during heating and cooling. Classificatio...Read more -
Residual Stress in Castings
Residual stress in metal castings is a significant issue that can affect the performance and longevity of metal components. Predicting and managing these stresses is crucial for ensuring the quality and durability of the final product. Prediction of Residual Stres...Read more
