What is a casting mold - the types of casting molds and the differences between them
Casting of steel parts is a process in which various and complex structures can be made.
Molds that are frequently used in the manufacture of castings are called permanent molds. The material of these molds is metal and is usually made of cast iron, steel and bronze. The choice of mold material is based on such things as the high melting point of the mold material compared to metal or cast alloy, having the least dimensional changes and the desired abrasion resistance. Permanent molds may be made by casting and then machined and polished to achieve the final dimensions. These molds are commonly used to make parts from metals and non-ferrous alloys such as aluminum, magnesium, zinc, lead, copper and their alloys, as well as to make parts from cast iron.
High production speed, dimensional accuracy and also creating desirable metallurgical specifications.
Molds that break down after each casting as the piece is removed are called temporary molds. These molds, whose constituents are generally in the form of a mixture of refractory sand particles; Adhesives and other materials can be made in three ways:
By pounding and compacting a wet mixture around the model; By applying a free-flowing mixture to the dry around the shell molding model; By freely releasing the mixture as a liquid slurry around the precision molding model.
