Thin - Walled Castings
★ Mass & Stable Production for Thin-Walled Castings
• Thin-walled ductile iron is the direction of light-weight solution.However, thin-walled molds will increase the follow resistance of molten iron in narrow spaces, resulting a rapid drop in temperature of molten iron and thus difficult for molten iron to fill the casting shape. As a result, castings are prone to have many defects including cold shut , inside cut, thickness error and mechanical properties changes.Achieving mass and stable production of thin-walled castings has always been a challenge in the foundry industry.
★ Core Strength
• By using self-innovated process design, HXW has achieved stable and mass production of a series complex differential carriers with the thinnest wall thickness of less than 5mm, and less than 2.6% overall defects rate.Total 200,000 pieces have been successfully exported, and their end-customers are all fortune 500 companies.
