Precision Casting for Stainless Steel Castings
Precision casting is also called investment casting. This casting process minimizes or does not cut during the casting process. It is a casting method with a wide range of applications, high dimensional accuracy of the casting, and excellent surface quality. It is not in...Read more -
Heat Treatment of Austenitic Stainless Steel Castings
The as-cast structure of austenitic stainless steel castings is austenite + carbide or austenite + ferrite. Heat treatment can improve the corrosion resistance of austenitic stainless steel castings. Equivalent Grade of Austenitic Stainless Steel AISI ...Read more -
Heat Treatment of Martensitic Stainless Steel Castings
Martensitic stainless steel refers to a type of stainless steel whose microstructure is mainly martensite. The chromium content of martensitic stainless steel is in the range of 12% - 18%, and its main alloying elements are iron, chromium, nickel and carbon. Martensitic ...Read more -
Chemical heat treatment of steel castings
The chemical heat treatment of steel castings refers to placing the castings in an active medium at a certain temperature for heat preservation, so that one or several chemical elements can penetrate the surface. Chemical heat treatment can change the chemical compositio...Read more -
No-Bake Sand Casting Process
Sand molds used in sand casting are classified into three types: clay green sand, clay dry sand, and chemically hardened sand according to the binder used in the sand and the way it builds its strength. No-bake sand is foundry sand th...Read more -
Normalization Heat Treatment for Steel Castings
Normalizing, also known as normalization, is to heat the workpiece to Ac3 (Ac refers to the final temperature at which all free ferrite is transformed into austenite during heating, generally from 727°C to 912°C) or Acm (Acm is In actual heating, the critical temperature...Read more -
Description, Reasons and Remedies of Common Sand Casting Defects
There are many reasons for sand casting defects in real sand casting process. But we can find the exact reasons by analyzing the defects inside and outside. Any irregularity in the moulding process causes defects in castings which may sometimes be tolerated. Usually the ...Read more -
Industrial Electrocoating Surface Treatment for Metal Castings and Machining Products
Industrial electrocoating is a widely used surface treatment for protecting the metal castings and CNC machining products from the corrosion with nice finish. Many customers ask questions about the surface treatment of metal castings and precision machined parts. This ar...Read more -
Cast Iron Castings VS Carbon Steel Castings
Cast iron castings have been used widely in industries and machineries since the modern foundry estabilished. Even in current times, the iron castings still play an important role in trucks, railroad freight cars, tractors, construction machineries, heavy duty equipment....Read more -
Advantages of Lost Foam Casting Process
Lost Foam Casting, which is also called LFC for short, uses the patterns remaining in the compacted dry sand mould (full mould). Therefore, the LFC is considered to be the most innovative large-scale series casting method for the production of complex metal castings of t...Read more -
Coated Sand Casting VS Resin Sand Casting
Coated sand mould casting and resin sand mould casting are two casting methods that are more and more widely used. In actual casting production, they are increasingly used to replace clay green sand casting. Although there are some similarities between resin sand and coa...Read more -
Resin Coated Sand Mold Casting Process
Resin sand is the molding sand (or core sand) prepared with resin as a binder. The resin coated sand casting is also called shell mold casting because the resin sand mold could be solid into a strong shell after heating of just at the room temperature (no-bake or self-ha...Read more
