About Casting Iron Parts
Product Features
Casting iron parts can exhibit different characteristics depending on the type of material chosen (e.g., Ductile Cast Iron, Gray Cast Iron, White Cast Iron, etc.). In this module, I will focus on the common characteristics of casting iron parts from different materials.
Good Shock Absorption
Because graphite is present in the composition of various cast iron materials, and graphite can effectively absorb mechanical vibration energy, the shock absorption performance of casting iron parts is better than that of other casting parts.
High Compressive Strength
Casting iron parts have a high compressive strength, with compressive strength close to that of steel, and are suitable for structural parts that are subjected to pressure.
Good Wear Resistance
Because the graphite in the material is a good lubricant, the graphite chips generated during the friction process can play a role in reducing friction, so the overall wear resistance of casting iron parts is better.
Material Selection
We at Sango customize casting iron parts for customers There are two main materials, namely Gray cast iron and Ductile cast iron. Below I will briefly introduce the grades, differences and most suitable application scenarios of these two types of materials that we use most often in Sango.

Common Applications
|
It is suitable for medium-strength structural parts and wear-resistant parts, commonly used in machine beds, bases, cabinets, etc.
|
It is used in structural parts and wear parts with high strength requirements, such as heavy machine tool beds, cylinder blocks of large engines, large gearboxes, etc.
|
It is commonly used for parts that need to withstand impact, bending or deformation, such as automobile wheels, chassis parts, valve bodies, gears, crankshafts, etc.

Casting Process Selection
There are many casting methods to produce casting iron parts, such as sand casting, investment casting, lost foam casting, etc. Choosing the right casting process can solve our production problems while saving costs. Below I will briefly describe the casting process suitable for cast iron.
Sand Casting
Sand Casting first makes the same pattern as the shape of the part, then puts the mold into the upper and lower sand boxes for molding, then takes out the mold to align and fix the upper and lower sand boxes, and slowly injects molten metal liquid through the pre-designed gate, and after cooling, the sand can be obtained by falling the sand.
Investment Casting
Investment casting, also known as lost wax casting, has a core difference in the use of wax molds to prepare molds. First, a wax mold consistent with the part is made, and then the wax pattern is coated with a refractory coating to make the mold shell. After the shell is prepared, it is dewaxed, that is, the wax mold is melted, and a cavity is formed inside the shell that is consistent with the part. After roasting, molten metal can be injected into the mold shell, and the finished product can be obtained by crushing the mold shell after cooling.
Lost Foam Casting
Lost foam casting is to use EPS to make molds, coat the foam molds consistent with the product with a layer of refractory material, dry them into the sand box and fill them with sand and press them, and then inject molten metal liquid into the gate, after the metal liquid touches the foam mold, the foam quickly vaporizes, and then the metal liquid fills the space of the foam mold, wait for cooling and solidification to dig out the dry sand, and clean up to obtain the finished product.
