Good casting design basic rules is critical to producing high quality, functional and durable castings during the manufacturing process. Here are some basic rules for good casting design.
- Simple geometric shapes
- Prioritize graphics
- Material Selection
- Avoid sharp thickness changes
- Avoid sharp corners and edges
- directed solidification
- Setting of risers and gating systems
- Consider manufacturing and assembly
- Reduce internal defects
Good casting design basic rules
Simple geometric shapes
- Castings should consist of geometrically simple bodies, such as cylinders, cones, cubes or spheres.
- This helps to simplify the mold design and manufacturing process.
Prioritize graphics
- Use prioritize graphics in preference to curved surfaces that follow simple curves.
- This reduces the risk of stress concentrations and deformation.
Material selection of good casting design basic rules
- The most suitable casting material is selected according to the type of stress expected.
- For example, for shock or vibration stresses, “brittle” flake graphite cast iron should not be used.
Avoid sharp thickness changes
- The wall thickness of the casting should be as uniform as possible, avoiding sudden thickness changes, which can lead to uneven cooling and defects.
Avoid sharp corners and edges
- Avoid Sharp corners and edges in the design as they can become stress concentration points that can lead to cracks and fractures.
Directional solidification
- The design should take into account the solidification direction of the casting to ensure that the liquid metal can fill the mold smoothly and reduce defects caused by shrinkage.
Setting of risers and gating systems
- Properly set up risers and gating systems to ensure a smooth flow of metal and to provide the necessary make-up contraction during solidification.
Consider manufacturing and assembly
- The design should consider the convenience of manufacturing and assembly in order to reduce production costs and improve product quality.
Reduce internal defects of good casting design basic rules
- Reduce the internal defects of castings, such as porosity, shrinkage holes, etc. through optimized design, so as to improve the overall quality of castings.
