CYLINDER BLOCK

“The production process steps depands on material and manufacturing method. The general production process for cast iron cylinder block is as follows:

1. Pattern Making: The design is created by a pattern or model, including wood, metal, or plastic materials.
2. Sand Mold Making: Packing a mixture of sand, clay, and water around the pattern to created a sand mold. The sand mold must be evenly packed, without any voids or defects.
3. Melting and Pouring: Molten iron is poured into the sand mold at a temperature 2,600℉ to 2,800℉. The molten iron flows through runners and gates into the mold.
4. Solidification and Cooling: The molten iron cools and solidifies within the sand mold, keeping mold in place until adequately cooled and solidified.
5. Shakeout and Cleaning: Broke the mold to get the casting, then clean the casting to remove the excess sand and impurities.
6. Machining: Machine by milling, drilling, honing, and other processes to achieve the final shape and dimensions.
7. Finishing: The cylinder block is finished by polishing, painting, and any other necessary treatments to improve the appearance and durability of the block.

Throughout the process, quality control measures are implemented to ensure the cylinder block meets all required specifications and standards.”
