What Is Gravity Casting Service

Our Gravity Casting Service leverages the natural force of gravity to produce high-quality metal components with excellent surface finish and structural integrity. Ideal for low-pressure, cost-effective casting of complex geometries with reduced energy consumption.

Benefits	Key Features
Cost-Effective Production	Gravity Casting offers an economical production method with reduced tooling costs and lower energy requirements. This process enables efficient high-volume batch production, minimizing overall manufacturing expenses while delivering competitive pricing for high-quality cast components.
Superior Surface Finish	Die cast parts exhibit a smooth and detailed surface finish that minimizes the need for secondary finishing. This efficiency reduces production time and cost while enhancing the aesthetic and functional quality of the component.
Enhanced Structural Integrity	Gravity Casting minimizes turbulence during the metal’s flow, which results in a refined grain structure and mechanical properties. The method yields cast components with strength, durability, and uniformity, ensuring reliable performance under demanding conditions.
Eco-Friendly Process	Operating at lower temperatures and pressures, Gravity Casting consumes less energy and produces reduced emissions compared to high-pressure alternatives. This method minimizes material waste and supports environmentally responsible manufacturing practices while ensuring superior efficiency.

Anodizing Cast Aluminum

Custom Parts Surface Finishing Available

Our Surface Treatment Service offers specialized finishes for custom parts, enhancing durability, aesthetics, and performance. We provide a range of processes, including Electroplating, Anodizing, Powder Coating, and Thermal Barrier Coatings, tailored to improve corrosion resistance, wear properties, and visual appeal of metal and plastic components across industries.

Design Element	Suggestions (Industry Standard Values)	Reasons and Benefits
Wall Thickness	Typical range: 3 - 8 mm (ideal ~5 mm)	Ensures proper metal flow, solidification, and reduces risk of shrinkage and porosity.
Corner Radii	Minimum internal radii: 2 - 4 mm	Reduces stress concentrations, improves flow characteristics, prevents cracking.
Draft Angles	Draft angle: typically 2° - 4° per side	Facilitates easy part removal from the mold, reduces mold wear and surface imperfections.
Fillets	Minimum internal fillet radii: 2 mm	Promotes metal flow, reduces stress concentration, and improves structural integrity.
Hole Sizes	Minimum hole diameter: 3 - 5 mm	Ensures mold filling, prevents incomplete castings, and reduces defect risks.
Undercuts	Avoid or minimize undercuts	Simplifies mold design, reduces complexity, and minimizes production costs and defects.
Surface Finish	Typical gravity casting roughness: Ra 6.3 - 12.5 µm	Provides a balance between achievable surface quality and cost efficiency.
Tolerances	Typical linear tolerance: ±0.5 mm per 25 mm	Represents achievable accuracy; tighter tolerances typically increase cost.
Text and Logos	Minimum text/logo depth/height: ≥ 1 mm	Ensures visibility and clarity in casting, suitable for gravity casting surface finish.
Ribs and Gussets	Thickness approximately 60 - 80% of adjacent walls	Adds structural strength without excessive shrinkage, porosity, or stress concentration.
Parting Line	Position at widest cross-section, simple and flat	Reduces flash and defects, simplifies mold construction, and improves cosmetic quality.
Machining Allowance	Typical allowance: 1.5 - 4 mm	Allows sufficient material for accurate machining and achieving final dimensions.
