Steel casting manufacturers tend to use wooden molds in the production process of large steel castings, despite the existence of various mold materials in the market, such as metal, plastic, rubber, etc. Why is this?

The cost-effectiveness of wooden molds is very significant. Compared to other materials such as metal, wood has much lower raw material costs and is easy to process and shape, which helps to reduce overall production costs. Especially for large cast steel parts that are not frequently reused in single piece or small batch production, this disposable mold material has a significant cost advantage.

2. Wooden molds have good processing flexibility. Wood is easy to cut, carve, and polish, and can be quickly processed and modified by steel casting manufacturers according to the design requirements of castings. At the same time, the lightweight nature of wooden molds is more conducive to workers' handling and installation, improving work efficiency.

3. Wooden molds have good natural gas release properties. During the casting process, the gas inside the mold needs to be discharged to avoid the formation of bubbles or defects, which helps to improve the internal quality of the castings.

4. Using wooden molds can help complete the production of molds in a short period of time, especially in urgent order requirements and production needs that can be quickly responded to.

5. Wooden molds have a shorter service life than metal molds and are not suitable for large-scale continuous production. They have significant advantages in terms of variable demand, speed, cost, and for single or small batches.

Steel casting manufacturers choose wooden molds based on comprehensive considerations such as cost, flexibility, gas release, and production cycle.
