The use of wooden pattern technology is particularly suitable for the production of large-sized castings such as large gear rings. 

The advantages are as follows: 1. Optimized casting fluidity: The wooden mold design takes into account the flow characteristics of the molten metal, reduces pores and shrinkage defects, and increases the service life of the gear ring by more than 20%.
2. Good surface treatment performance: The surface of the wooden mold can be coated with paint or other protective layers to improve the surface finish and service life.
3. Flexible design modification capabilities: The wooden mold can be adjusted and modified at any time according to the special requirements of the customer to ensure that the final product fully meets the customer's application environment requirements.
4. Mature process: The technicians are experienced and the process is stable and reliable.
5. Model flexibility: For large gear rings, segmented mold making is often required. Wooden molds are easy to split and assemble, which is more suitable for the needs of casting processes.
6. Shorter delivery cycle: The short production cycle of wooden molds can shorten the delivery time by 15-25 days, helping customers speed up equipment maintenance or new project commissioning.
