As living standards continue to improve, people are increasingly placing greater emphasis on quality of life and aesthetic enjoyment. One area that has gained significant attention is the rapidly growing decoration and renovation industry. Through continuous product upgrades and quality improvements, combined with the domestic price advantages of leveling machines, manufacturers are able to compete more effectively in the market. For leveling machines, there are several key requirements for their castings: ensuring the accurate fluidity of the alloy, preventing the casting walls from being too thick, maintaining uniform wall thickness throughout the casting, ensuring rational connections between walls with proper fillet structures, avoiding large horizontal surfaces wherever possible, and preventing any obstruction during casting shrinkage.
