1. **Classification by shape**
- **Square mold**: used to make standard-sized floor tiles, suitable for areas such as courtyards and corridors.
- **Long strip mold**: often used for paving roads or decorative borders.
- **Special-shaped mold**: including round, polygonal or other special shapes, suitable for complex architectural design needs.
2. **Classification by material**
- **Wooden mold**: commonly used in traditional crafts, with the advantages of easy processing and low cost, but poor durability.
- **Metal mold**: such as steel mold, durable and high precision, suitable for large-scale industrial production.
- **Plastic mold**: light and easy to shape, but usually used for small or temporary projects.
3. **Classification by process**
- **Dry pressing mold**: the soil is compressed and formed by high pressure, suitable for floor tiles with higher hardness.
- **Wet mold**: the mold is injected with mud with high water content, suitable for floor tiles with strong flexibility.
