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 -
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 -
Radiographic Inspection of Castings
Radiographic Inspection of Castings 1. The basic principle of radiography In the process of penetrating the casting, X-ray or γ-ray interacts with the material, and its intensity is attenuated by absorption and scattering. Images with varying degrees of blackness ...Read more -
Silica Sol Binder In Investment Casting
The choice of silica sol coating will directly affect the surface roughness and dimensional accuracy of investment castings. Silica sol coatings generally can directly select silica sol with a mass fraction of silica of 30%. The coating process is simple and the operatio...Read more -
Chills for Metal Casting
Chill is the chilled material placed inside the cavity, the surface of the cavity and the inside of the mold in order to speed up the local cooling rate of the casting. The chills are used in conjunction with the gating system and the riser system to control the solidifi...Read more -
